Mindful Eating for Your Body and Mind

Starting a new weight loss treatment can feel like a breakthrough - especially for women who have spent years struggling with PCOS, irregular cycles, or stubborn weight gain. Many people using GLP-1 medication describe renewed energy, steady progress on the scale, and a sense of hope. But alongside these benefits, some also notice unexpected changes in their menstrual cycle - such as new cramping, spotting, or shifts in flow.

It’s natural to wonder: Is this normal? Is it the medication, or just my body adjusting?

If you’ve had similar questions, you’re not alone. As more women turn to Mounjaro for weight management or type 2 diabetes, new conversations are opening up about its impact on menstrual health.

Changes in your cycle can feel unsettling, particularly when they appear alongside a new treatment. Whether it’s lighter or heavier bleeding, unfamiliar cramps, or questions about how Mounjaro may interact with hormones, contraception, or PCOS, it’s important to have clear, UK-specific information.

In this blog, we’ll explore how Mounjaro may affect the menstrual cycle, and share practical ways to manage symptoms and stay informed - so you can feel supported, not confused, as you move forward on your health journey.

The Hormonal Connection: How Mounjaro Might Influence Menstrual Cycles

Mounjaro works by mimicking two naturally occurring gut hormones - GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide). Together, these hormones help to slow down gastric emptying, reduce appetite, improve insulin sensitivity, and lower blood glucose levels. While these effects are primarily targeted at metabolic regulation and weight loss, they also have indirect impacts on the hormonal systems that control the menstrual cycle. 

For women, especially those with underlying hormonal conditions like polycystic ovary syndrome (PCOS), even small shifts in insulin levels, body weight, or inflammation can have a ripple effect on oestrogen balance, ovulation patterns, and menstrual symptoms. This means that although Mounjaro is not designed to act on reproductive hormones, its metabolic actions can influence menstrual health in meaningful ways.

Indirect Effects via Weight Loss

1. Weight and Hormones

One of the most significant ways Mounjaro may influence the menstrual cycle is through weight loss, which has a profound effect on hormonal balance. Body fat is not just stored energy, it’s hormonally active. Excess adipose tissue increases the production of oestrogen through a process called aromatisation. 

When oestrogen levels are too high, it can disrupt the delicate hormonal interplay that governs the menstrual cycle, leading to irregular or absent periods, heavy bleeding, and painful cramps. By promoting steady and sustained weight loss, Mounjaro can help rebalance oestrogen levels, restoring hormonal equilibrium and contributing to more predictable menstrual patterns.

2. Benefits of Weight Loss on Menstrual Health

In addition to regulating oestrogen, healthy weight loss brings broader benefits to menstrual health. Studies have shown that losing weight can lead to more regular cycles, a reduction in PMS symptoms, and a decrease in systemic inflammation, which is a known contributor to period pain. Weight loss also significantly improves insulin sensitivity, a crucial factor for women with PCOS.

A 2025 clinical study in women with PCOS and obesity (n=56) found tirzepatide led to significant weight reduction (mean 9.54%) and improvement in menstrual regularity: irregular cycles decreased from 85.7% before treatment to 32.1% after. There was also a notable drop in prevalence of ovarian cysts and insulin resistance

PCOS-Specific Considerations

For those living with PCOS - a condition that affects up to 1 in 10 women in the UK - Mounjaro’s impact can be particularly positive. By improving insulin resistance, one of the root causes of PCOS, Mounjaro can help restore more regular ovulation, reduce elevated androgen levels (which cause symptoms like acne, excess facial hair, and scalp hair thinning), and potentially enhance fertility. While not licensed specifically for PCOS in the UK, Mounjaro’s metabolic benefits can offer meaningful hormonal improvements for many women living with this condition.

Based on survey data from 1,754 users of GLP-1 medications (including tirzepatide) showed that 27% noticed changes in their menstrual cycles after starting treatment. Respondents with PCOS were even more likely to report changes (43%), with the most common being more predictable, more frequent, or shorter periods. However, rigorous clinical trial data specifically for tirzepatide remain limited

Direct Effects? What the Evidence Says

Despite anecdotal reports, there’s limited clinical trial data on Mounjaro’s direct impact on menstruation. Current studies haven’t flagged menstrual changes or cramps as common side effects. The MHRA and manufacturer’s patient information leaflets for Mounjaro in the UK do not list period changes as a primary or expected adverse effect.

However, real-world experiences from patients on forums and social media have started highlighting menstrual irregularities, delayed periods, or changes in cramp severity - pointing to a potential area for future research.

Mounjaro and Period Cramps: Perspectives and Patient Experiences

What Are Women Reporting?

Although formal studies are currently limited, many women taking Mounjaro have shared a range of personal experiences on social media related to their menstrual cycle. Some report that their periods have become lighter and less painful, while others have noticed delayed cycles, spotting, or even more intense cramps during the initial adjustment phase. These changes may not be due to the medication directly, but rather indirect effects of weight loss, which can influence hormonal balance. 

Fluctuations in oestrogen, insulin, and leptin levels - all of which are sensitive to changes in body weight and metabolic health - could contribute to these menstrual changes. Additionally, some of the side effects commonly associated with Mounjaro, such as nausea or abdominal discomfort, may overlap with or intensify typical menstrual symptoms, making it harder to distinguish the cause.

Potential Reasons for Improvement in Cramps

1. Reduced Inflammation

Mounjaro-induced weight loss can lower systemic inflammation - a major driver of dysmenorrhoea (painful periods).

2. Hormonal Regulation

Stabilising insulin and oestrogen levels may help with:

• Less uterine muscle hyperstimulation
  
  
• Fewer prostaglandin surges (compounds linked to cramping)

Could Mounjaro Make Cramps Worse?

While many women experience improvements in their menstrual symptoms with Mounjaro, it’s also possible for some to notice a temporary worsening of cramps or cycle disturbances. This can happen for several reasons. Rapid weight loss, especially in the early stages of treatment, can place stress on the body and temporarily disrupt hormonal balance, leading to more intense cramps or irregular periods. Additionally, as the body undergoes hormonal fluctuations during weight loss, menstrual cycles may become less predictable for a time.

Another important factor to consider is that Mounjaro slows gastric emptying, which may affect how oral medications are absorbed - including combined oral contraceptive pills and oral HRT. If the absorption of these hormones is reduced, hormone levels in the body may drop, potentially causing breakthrough bleeding, spotting, or a return of menstrual symptoms such as cramping or irregular flow. This is particularly relevant for women who rely on these medications for menstrual regulation or symptom control and highlights the importance of discussing contraceptive or HRT options with a healthcare provider when starting Mounjaro.

Gastrointestinal Side Effects and Menstrual Discomfort

Mounjaro can cause:

• Nausea
  
  
• Constipation
  
  
• Diarrhoea
  
  
• Abdominal discomfort

These may overlap with PMS symptoms, making it harder to distinguish between side effects and menstrual pain.

Important Considerations for Users on Mounjaro

1. Contraception and Mounjaro

For women using Mounjaro, there are several important factors to consider when it comes to menstrual health, contraception, and hormone therapy. One of the key concerns is how Mounjaro may affect the absorption of oral medications due to its action of slowing gastric emptying. This can potentially reduce the effectiveness of oral contraceptive pills, putting users at risk of unintended pregnancy.

Current guidance suggests using a barrier method, such as condoms, for at least four weeks after starting Mounjaro and for four weeks after each dose increase. Alternatively, women may wish to speak to their GP about switching to non-oral forms of contraception, such as patches, IUDs, or implants, which are not affected by changes in digestion.

NHS and Manufacturer Recommendations:

• Use a barrier method (like condoms) for at least 4 weeks after starting Mounjaro
  
  
• Also apply the 4-week barrier rule after each dose increase
  
  
• Consider switching to non-oral forms of contraception (e.g., patch, IUD, implant)

2. Hormone Replacement Therapy (HRT)

Women taking hormone replacement therapy (HRT) during the perimenopausal or menopausal period should be aware that oral HRT may also be impacted. The British Menopause Society advises considering transdermal options, like patches or gels, which bypass the digestive system and maintain more stable hormone levels. In some cases, adjusting the dose of oral progesterone may be necessary, but this should only be done in consultation with a healthcare provider.

3. Track Your Cycle

Tracking your menstrual cycle becomes particularly important while on Mounjaro. Noting changes in cycle length, flow, cramping, mood swings, or energy levels can help identify any emerging patterns or concerns. You should seek medical advice if you experience significant changes, such as missed periods, unusually heavy or light bleeding, persistent or worsening cramps, or unexpected spotting - especially if you're on HRT or haven’t had periods for some time. These could signal hormonal imbalances, medication side effects, or other underlying issues that need attention. Use apps like Clue or Flo, or simply note symptoms in a calendar.

Managing Menstrual Symptoms While on Mounjaro

Managing menstrual symptoms while on Mounjaro involves a holistic approach that supports both hormonal balance and overall wellbeing. 

1. Supportive Lifestyle Habits

Start by focusing on lifestyle habits that naturally ease period discomfort. A balanced diet rich in whole grains, leafy greens, lean proteins, and healthy fats can help stabilise blood sugar levels and reduce inflammation - both of which may play a role in period cramps and mood changes. Including foods high in magnesium (like nuts, seeds, and dark chocolate) and omega-3 fatty acids (like salmon or flaxseeds) may also help reduce cramping.

Staying physically active is another powerful tool - gentle exercises like walking, stretching, or yoga can increase blood flow, reduce tension, and improve your overall sense of wellbeing during your cycle. Hydration and adequate sleep support hormone regulation and can ease fatigue and bloating, while stress-reducing activities like meditation, journaling, or even warm baths may help ease both mental and physical premenstrual symptoms.

2. Pain Relief Options

For pain relief, over-the-counter medications such as paracetamol or ibuprofen can be effective in managing cramps. However, it’s important to use them cautiously if you’re experiencing gastrointestinal side effects from Mounjaro like nausea or constipation. 

3. Complementary Therapies

Some people also find comfort in non-pharmacological methods like applying a hot water bottle to the lower abdomen, using herbal teas like chamomile or ginger, or taking magnesium supplements - though any supplement should be discussed with your GP to ensure it's safe alongside your current medications.

4. Communicate with Your Healthcare Provider

Lastly, open communication with your healthcare provider is essential. If your cycle becomes irregular, if cramps worsen, or if you experience any unexpected symptoms such as spotting, prolonged bleeding, or missed periods, it’s important to seek professional advice. Your doctor can help determine whether these changes are related to Mounjaro, weight loss, hormonal shifts, or another underlying cause, and guide you on the best course of action.

Conclusion

Mounjaro is a powerful medication with proven benefits for weight loss and metabolic health. For many women, these benefits may translate into more regular and less painful periods, especially for those with PCOS or insulin resistance. However, it’s essential to understand that period changes are not officially listed as side effects but do occur anecdotally. Menstrual cramps may improve or worsen depending on your hormonal baseline and weight loss pace. Mounjaro can affect hormonal contraceptives and HRT absorption, which requires additional precautions. Being proactive, tracking your cycle, choosing the right contraceptives, and staying in touch with your GP, ensures that you can reap the benefits of Mounjaro without sacrificing menstrual health.

Weight loss journeys are about more than numbers on a scale. For women, especially, they often involve complex hormonal shifts.

Imagine this: you’re a busy woman juggling work, family commitments, and your own well-being. You’ve decided to try GLP-1 medication to support your weight loss journey and are feeling hopeful about the potential benefits. But despite your efforts, you're wondering—why isn’t the weight coming off as quickly as you’d like? 

Is there something more you could be doing to optimise the medication’s effects? The truth is, while GLP-1 drugs like semaglutide and tirzepatide can significantly help reduce appetite and improve satiety, the way you time your meals plays a crucial role in enhancing these benefits.

Meal timing is often overlooked when it comes to weight loss, but it’s a powerful tool that can work synergistically with GLP-1 medication to maximise its effects. Busy lifestyles can make consistent meal planning challenging, understanding how meal timing influences weight loss could make all the difference. What if you could boost the appetite-suppressing effects of GLP-1 drugs just by making simple adjustments to when you eat? What if those small changes in your meal schedule could help stabilise your blood sugar, enhance your energy, and improve your results?

How GLP-1 Medications Work: A Scientific Breakdown

GLP-1 medications act by engaging specific receptors throughout the body, with three primary mechanisms contributing to their effectiveness:

1. Delayed Gastric Emptying: GLP-1 slows the rate at which food leaves the stomach. This not only promotes a feeling of fullness but also regulates post-meal blood sugar spikes. A clinical trial demonstrated that patients taking semaglutide experienced significantly slower gastric emptying, leading to reduced caloric intake by approximately 20% per meal.
   
   
2. Appetite Suppression: By interacting with brain centres, particularly the hypothalamus, GLP-1 drugs reduce hunger signals. A study found that GLP-1 receptor agonists effectively decrease cravings for high-fat, high-sugar foods, supporting healthier eating patterns.
   
   
3. Insulin Sensitivity and Glucose Control: GLP-1 stimulates insulin release and inhibits glucagon secretion, ensuring stable blood sugar levels. This effect was confirmed in a trial which reported improved HbA1c levels in 83% of participants using liraglutide for 24 weeks.

The Role of Meal Timing in Mitigating Side Effects of GLP-1 Medications

While GLP-1 medications offer substantial benefits, their side effects can sometimes pose challenges. Common side effects include:

• Nausea and Vomiting: The delayed gastric emptying that supports weight loss can lead to discomfort if portions are too large or meals are poorly timed.
• Bloating and Gas: These symptoms often arise when the gut adjusts to slower digestion.
• Diarrhoea or Constipation: Altered gut motility can impact bowel habits, depending on dietary intake and hydration levels.

Practical Ways to Mitigate Side Effects

Meal timing and composition are crucial in minimising discomfort while optimising the benefits of GLP-1 drugs. Here are evidence-based strategies:

1. Eat Smaller, Balanced Meals:
   
   • A study suggested that consuming smaller, nutrient-dense meals reduces nausea and supports better digestion. Meals rich in protein, fibre, and healthy fats are particularly effective.
   • For example, choose a small bowl of Greek yogurt with chia seeds for breakfast instead of a heavy fry-up.
2. Avoid Overeating: Overloading the stomach can amplify nausea and bloating. A clinical trial highlighted that patients who divided meals into smaller portions experienced fewer side effects than those who consumed three large meals daily.
3. Time Meals Around Medication:
   
   • Some individuals benefit from taking GLP-1 medications in the evening to minimise nausea during the day, as suggested in a  review.
   • For others, eating 30 minutes after administration allows the medication’s initial effects to settle before digestion begins.
4. Stay Hydrated and Include Probiotics: Adequate hydration and gut-friendly foods, such as live-culture yogurts, support digestion and combat constipation caused by slower gut motility.
5. Low-Glycaemic Foods: Incorporate foods like lentils, oats, and quinoa to keep blood sugar stable while minimising the risk of nausea or lightheadedness associated with rapid glucose changes.

The Science of Meal Timing: A Key to Effective Weight Management

Meal timing is more than just when you eat—it’s a powerful tool that influences metabolic processes, insulin sensitivity, and overall health. Research has increasingly highlighted the connection between the timing of meals and metabolic flexibility, which is the body’s ability to efficiently switch between burning carbohydrates and fats for energy. For individuals seeking to manage weight, improve blood sugar control, or maximise the effects of medications like GLP-1 agonists, understanding the science of meal timing can make a significant difference.

What Is Metabolic Flexibility and Why Is It Important?

Metabolic flexibility refers to the body’s capacity to adapt its fuel source based on availability. For instance, during periods of fasting, the body shifts from burning glucose to relying on stored fats. When metabolic flexibility is impaired—a common issue in obesity or type 2 diabetes—the body struggles to efficiently switch between these energy sources, leading to insulin resistance and increased fat storage.

A study found that individuals with high metabolic flexibility were more likely to maintain a healthy weight and had lower risks of metabolic disorders compared to those with inflexibility. Moreover, those who adhered to meal timing strategies, such as time-restricted eating (TRE), exhibited enhanced metabolic efficiency and improved fat oxidation.

The Role of Meal Timing in Insulin Sensitivity

Insulin sensitivity fluctuates throughout the day, peaking in the morning and gradually declining by evening. This diurnal rhythm highlights why eating earlier in the day is often linked to better glucose control and weight management outcomes.

A study revealed that participants who consumed the majority of their calories earlier in the day had improved insulin sensitivity and lower fasting glucose levels than those who ate late at night.

Another clinical trial found that individuals who shifted their dinner to an earlier time and avoided late-night eating lost more weight and reported reduced cravings.

Meal Timing and Blood Sugar Control

Meal timing also directly impacts blood sugar regulation. Late-night eating, for instance, can lead to higher post-meal glucose levels, decreased fat oxidation, and increased fat storage. Conversely, strategic timing of meals can promote steady blood sugar levels and reduce the risk of insulin resistance.

Key Findings from studies:

• A study demonstrated that individuals with type 2 diabetes who adopted an early eating window had significantly better glycaemic control and required less medication compared to those following a traditional eating schedule.
• The concept of "circadian eating," which aligns meals with the body’s natural rhythms, has shown promise in reducing HbA1c levels and improving overall metabolic health.

Practical Applications of Meal Timing

1. Start Your Day with a Balanced Breakfast: Research consistently supports the benefits of eating a nutrient-rich breakfast. A study reported that consuming a high-protein breakfast improved satiety, reduced calorie intake later in the day, and enhanced metabolic flexibility. Choose oatmeal topped with chia seeds, nuts, and fresh berries to kickstart the day.
2. Adopt Time-Restricted Eating (TRE): TRE involves eating within an 8-10 hour window and fasting for the remaining hours. Clinical trials showed that overweight participants who followed TRE lost more weight and had improved cholesterol levels without intentionally reducing caloric intake.
3. Limit Late-Night Eating: Avoid heavy meals close to bedtime to support insulin sensitivity and reduce fat storage. Opt for a light snack, such as a handful of nuts or a slice of avocado, if evening hunger strikes.
4. Synchronise with GLP-1 Medications: For those using GLP-1 drugs, meal timing can reduce side effects and maximise satiety. Eating smaller, nutrient-dense meals spaced evenly throughout the day helps prevent nausea and ensures sustained energy levels.

Tailoring Meal Timing to GLP-1 Medication: Optimising Weight Loss and Metabolic Health

Combining effective meal timing strategies with GLP-1 medications can significantly enhance weight loss outcomes. Approaches such as time-restricted eating (TRE), intermittent fasting (IF), and strategic meal timing with a low-carbohydrate diet can complement the appetite-regulating effects of GLP-1 drugs while promoting better metabolic health. This tailored approach is especially beneficial for women seeking to optimise weight management without compromising their nutritional needs.

Time-Restricted Eating (TRE): A Structured Approach

TRE involves consuming all meals within a specific time window, typically ranging from 8 to 12 hours, followed by a fasting period. This pattern aligns with the body's natural circadian rhythms, improving metabolic flexibility and insulin sensitivity.

A study found that individuals following TRE with an 8-hour eating window reduced their body weight, improved fasting glucose, and showed reduced appetite compared to those eating over a 12-hour window. Another clinical trial reported that combining TRE with GLP-1 medications, such as semaglutide, amplified weight loss effects by controlling hunger and reducing calorie intake.

How to Implement TRE Safely

• Start with a 12-hour eating window (e.g., 8 a.m. to 8 p.m.) and gradually shorten it to 8-10 hours as tolerated.
• Schedule meals to coincide with peak GLP-1 medication effects, typically a few hours after administration, to maximise satiety.
• Prioritise nutrient-dense meals to avoid deficiencies during the fasting period.

Begin your day with a high-protein breakfast at 8 a.m., have a balanced lunch at 1 p.m., and finish with a light dinner by 6 p.m.

Intermittent Fasting (IF): Flexible Options for Women

Intermittent fasting offers multiple protocols, making it easier to customise based on individual preferences and lifestyles. The two most popular options include:

• 16/8 Method: 16 hours of fasting followed by an 8-hour eating window.
• 5:2 Diet: Five days of regular eating and two non-consecutive days of calorie restriction (500-600 calories).

A study compared the effects of IF and continuous calorie restriction, finding that IF led to similar weight loss but greater reductions in fasting insulin and inflammation markers. Women using GLP-1 medications, such as liraglutide, reported better appetite control when combining IF with the drug, as shown in a study.

Potential Benefits and Drawbacks

• Benefits: Improved insulin sensitivity, reduced calorie intake, and flexibility in food choices.
• Drawbacks: Women may experience hormonal disruptions with aggressive fasting patterns, especially during reproductive years.

How to Implement IF with GLP-1 Drugs

• Choose a protocol that aligns with your schedule and GLP-1 medication dosing. For instance, if using a once-weekly drug like Wegovy, plan fasting days away from side-effect peaks.
• Ensure meals during eating windows are rich in protein, healthy fats, and fiber to sustain energy levels.

Low-Carbohydrate Diet with Strategic Meal Timing

A low-carbohydrate diet focuses on reducing carb intake while increasing protein, fiber, and healthy fat consumption. When paired with strategic meal timing, this diet can enhance the effects of GLP-1 medications by stabilising blood sugar levels and promoting satiety.

Research found that low-carb diets led to greater reductions in HbA1c levels and body weight compared to low-fat diets. A study showed that combining a low-carb diet with GLP-1 medications significantly reduced cravings for high-carb foods, supporting long-term adherence.

How to Implement a Low-Carb Diet with Meal Timing

1. Morning: Start with a high-protein breakfast to boost satiety and stabilise blood sugar for the day.
   Example: Scrambled eggs with avocado and sautéed spinach.
2. Midday: Plan a balanced lunch rich in lean protein, fiber, and healthy fats.
   Example: Grilled chicken salad with mixed greens, nuts, and a vinaigrette.
3. Evening: Opt for a lighter, low-carb dinner to align with lower insulin sensitivity in the evening.
   Example: Grilled salmon with steamed broccoli and a side of quinoa.
4. Snacks: Include low-carb options such as nuts, seeds, or Greek yogurt to curb hunger between meals.

Practical Tips for Women: Meal Planning and Timing for Weight Loss with GLP-1 Medications

Balancing weight loss goals, GLP-1 medication regimens, and a busy lifestyle can be challenging, especially for women juggling work, family, and personal health. Meal planning and timing tailored to individual schedules can help overcome common barriers and optimise the effectiveness of GLP-1 medications.

1. Align Meals with GLP-1 Medication Effects

GLP-1 medications, such as semaglutide or tirzepatide, are designed to regulate appetite and slow gastric emptying, making meal timing critical to achieving sustained satiety and preventing overeating. A study showed that patients on GLP-1 medications experienced greater appetite suppression and weight loss when meals were timed to coincide with peak drug effects. For example, if a GLP-1 medication is injected in the morning, having the first meal 1-2 hours later ensures maximum appetite control.

Tip: Schedule meals 1-2 hours post-injection to coincide with peak satiety effects. Avoid skipping meals, as this may lead to overeating later in the day.

2. Incorporate Balanced, Pre-Portioned Meals

Designing nutrient-dense meals that balance protein, fiber, healthy fats, and carbohydrates can help sustain energy and manage hunger. A study highlighted the importance of high-protein, high-fiber meals in reducing cravings and enhancing satiety during weight loss interventions.

Example Meal Plan

• Breakfast: A smoothie with Greek yogurt, spinach, chia seeds, and almond butter.
• Lunch: A grilled chicken salad with avocado, nuts, and olive oil-based dressing.
• Dinner: Baked salmon with roasted vegetables and quinoa.

Tip: Use meal prep containers to portion meals in advance for quick access during busy days.

3. Time Meals to Enhance Metabolism and Energy Levels

Eating smaller, nutrient-dense meals at consistent intervals can help stabilise blood sugar and improve metabolic flexibility, especially when taking GLP-1 medications. A study  found that meal timing synchronised with circadian rhythms enhanced insulin sensitivity and reduced weight gain.

Time Your Meals

• Morning: Consume a protein-rich breakfast within 1-2 hours of waking.
• Afternoon: Schedule a balanced lunch around midday to prevent energy slumps.
• Evening: Opt for a light, low-carb dinner at least 2-3 hours before bedtime to align with the body’s natural metabolic rhythms.

4. Simplify Planning with Quick and Family-Friendly Recipes

For women managing family commitments, preparing meals that cater to everyone’s needs can save time and reduce stress.

Quick, Family-Friendly Options

• One-Pan Dishes: Stir-fried chicken and vegetables with sesame oil.
• Batch Cooking: Make a large pot of lentil soup and freeze portions for later use.
• Customisable Meals: Build-your-own tacos or grain bowls with options like grilled proteins, beans, and vegetables.

Tip: Use a slow cooker or air fryer to prepare meals with minimal effort.

5. Overcome Common Challenges

Challenge 1: Lack of Time for Meal Prep

• Solution: Dedicate an hour on weekends to prep ingredients, such as washing and chopping vegetables or portioning proteins.

Challenge 2: Eating Out or On-the-Go

• Solution: Choose grilled or baked proteins, opt for salads with vinaigrette dressing, and avoid fried foods.

Challenge 3: Adhering to a Routine

• Solution: Set reminders on your phone for meals and snack times. Use meal planning apps to track progress and stay organised.

Research found that using reminders and structured meal plans significantly improved adherence to dietary regimens, particularly in women undergoing weight loss treatments.

6. Stay Hydrated and Snack Smart

Drinking water and choosing nutrient-rich snacks can prevent dehydration and keep hunger at bay between meals.

Snack Ideas

• A handful of nuts and seeds.
• Veggie sticks with hummus.
• A boiled egg with a sprinkle of paprika.

Tip: Keep healthy snacks in your bag or car for emergencies.

7. Involve Family Members

Involving loved ones in meal planning fosters a supportive environment and ensures everyone benefits from healthier choices.

Tip: Assign tasks like setting the table or selecting recipes to encourage participation.
