High-Intensity Interval Training (HIIT) has rapidly gained traction across the UK as one of the most efficient workout methods for weight loss and overall fitness. For women navigating the demands of modern life be it careers, family commitments, or personal pursuits, finding time-efficient and effective ways to maintain health is paramount. HIIT emerges as a solution that not only fits into tight schedules but also delivers impressive results.
According to the NHS, approximately 29% of women in England are classified as obese, and an additional 31% are overweight. These statistics underscore a pressing need for accessible, effective weight loss strategies tailored to women's unique physiological and lifestyle needs. This guide delves into how HIIT can be a transformative tool for women aiming to shed pounds, boost their health, and enhance their quality of life.
What is HIIT?
HIIT stands for High-Intensity Interval Training, a workout methodology characterised by short bursts of intense exercise alternated with periods of rest or low-intensity movement. This training style is designed to maximise calorie burn and improve cardiovascular fitness more efficiently than traditional steady-state exercises.
Core Principles of HIIT
- Intensity: Engaging in exercises at 80-95% of your maximum heart rate. This level of effort pushes your body out of its comfort zone, leading to significant physiological adaptations.
- Intervals: Structured periods of high-intensity activity (typically 20 seconds to 2 minutes) followed by rest or active recovery periods of equal or longer duration.
- Duration: HIIT workouts are concise, generally lasting between 15 to 30 minutes, making them ideal for busy schedules.
Variations of HIIT
Understanding different HIIT variations allows you to select a style that aligns with your preferences and fitness level.
- Tabata Training: Originating from Japan, this protocol involves 20 seconds of maximum effort followed by 10 seconds of rest, repeated eight times for a total of four minutes. It's highly effective for improving aerobic and anaerobic capacity.
- EMOM (Every Minute on the Minute): Perform a specific number of repetitions at the start of every minute. The quicker you complete them, the more rest you have before the next minute begins. This format builds endurance and pacing.
- Circuit Training: Rotate through a series of exercises targeting different muscle groups with minimal rest in between. This keeps your heart rate elevated and muscles engaged throughout the session.
- Fartlek Training: A Swedish term meaning "speed play," this involves varying your speed and intensity at random intervals during activities like running or cycling.
Each variation offers unique benefits. For instance, Tabata is excellent for those looking to improve speed and power, while circuit training is beneficial for full-body conditioning.
How Can HIIT Help with Weight Loss?
HIIT's effectiveness in weight loss is supported by a growing body of scientific research. It combines cardiovascular and strength training elements, leading to comprehensive fitness improvements.
The Science Behind HIIT's Effectiveness
Increased Calorie Burn
HIIT workouts can burn significantly more calories in a shorter time compared to traditional exercise forms. A research study found that HIIT burns 25-30% more calories than other forms of exercise like weight training, cycling, and running on a treadmill.
EPOC Effect (Excess Post-exercise Oxygen Consumption)
One of HIIT's most significant advantages is the EPOC effect, commonly known as the "afterburn." After intense exercise, your body consumes more oxygen to restore itself to its resting state, burning additional calories in the process. This elevated metabolic rate can last for up to 24 hours post-workout, enhancing overall calorie expenditure.
Muscle Building and Metabolism Boost
HIIT stimulates muscle protein synthesis due to the resistance and anaerobic components involved. Building lean muscle mass is crucial because muscle tissue burns more calories at rest than fat tissue. The American Council on Exercise explains that increased muscle mass leads to a higher resting metabolic rate, aiding long-term weight management.
Cardiovascular and Health Benefits
Heart Health Improvement
HIIT has been shown to enhance cardiovascular function by increasing VO2 max—the maximum rate of oxygen consumption measured during incremental exercise. The British Heart Foundation notes that regular HIIT sessions can reduce blood pressure and lower the risk of heart disease.
Blood Sugar Regulation
For women at risk of type 2 diabetes or those with insulin resistance, HIIT can improve insulin sensitivity. A study in Diabetes Care found that HIIT significantly reduced blood glucose levels in participants with type 2 diabetes (Little et al., 2011).
HIIT for Women: Addressing Specific Concerns
While HIIT offers numerous benefits, it's essential to address specific concerns women may have to ensure the training is both safe and effective.
Common Concerns
Intensity Levels
Many women worry that HIIT may be too demanding, especially if they are new to exercise or returning after a hiatus. The high-intensity nature can seem intimidating, but HIIT is adaptable to all fitness levels.
Safety and Risk of Injury
The rapid movements and high-impact exercises in HIIT can increase the risk of injuries if not performed correctly. Concerns about joint health, particularly knees and ankles, are common.
Hormonal Fluctuations
Women's hormonal cycles can affect energy levels, endurance, and strength. Understanding how to adjust workouts during different menstrual phases is crucial.
Modifications for Safety and Comfort
Customising HIIT workouts can mitigate risks and enhance enjoyment.
Beginner-Friendly Adjustments
- Lower Impact Options: Replace high-impact moves like jump squats with bodyweight squats.
- Reduced Intensity: Start with a 1:2 work-to-rest ratio (e.g., 20 seconds of work, 40 seconds of rest).
- Simplified Exercises: Opt for exercises that are easier to perform with correct form.
Exercise Modification Table
Impact of Menstrual Cycle
The NHS suggests that moderate exercise during menstruation can alleviate cramps and boost mood. However, during the luteal phase (post-ovulation), energy levels may dip. Adjusting HIIT intensity during these times can help maintain consistency without overexertion.
HIIT and PCOS
Polycystic Ovary Syndrome (PCOS) affects approximately 1 in 10 women in the UK, leading to symptoms like weight gain and insulin resistance. According to Verity, a UK-based PCOS charity, incorporating HIIT into exercise routines can improve insulin sensitivity and support weight management. A study in the Journal of Clinical Endocrinology & Metabolism found that HIIT significantly reduced insulin resistance in women with PCOS (Harrison et al., 2012).

If you have been using Wegovy® as part of your weight-loss journey, you may have heard some exciting news: a new 7.2mg dose is now available in the UK.
At SheMed, we know that many of our patients make incredible progress but eventually hit a "plateau" - that frustrating point where weight loss slows down or stops. In the past, some patients felt they had to switch to other medications like Mounjaro® to keep seeing results.
That has now changed. With the arrival of the 7.2mg dose, you can achieve powerful weight loss results while staying on the Wegovy medication you already know and trust.
What is the 7.2mg dose?
In the past, the highest dose of Wegovy® was 2.4mg per week. For many people, this works perfectly. However, new research shows that some people benefit from a higher dose to help them feel full for longer and improve their metabolism.
The 7.2mg dose is a "step up" for patients who are already doing well on the 2.4mg dose but need a little extra help to see further results.
Why this is a "Game Changer" for Weight Loss
- No Need to Switch: You no longer have to worry about the hassle of switching brands or starting over with a different medication to get a stronger effect.
- Match the Competition: This higher dose allows Wegovy to offer the same high-level weight loss power that was previously only seen with other leading treatments.
- Beat the Plateau: If your weight loss has stalled at the 2.4mg dose, this "step up" helps restart your progress and keeps you moving toward your goal.
Important Safety Information
It is important to remember that 7.2mg is not for beginners. * Follow the Steps: Everyone must still start at the lowest dose (0.25mg) and slowly work their way up.
- Build Tolerance: You can only move to 7.2mg if you have been on the 2.4mg dose for a while and your body is handling it well.
- Side Effects: Just like with your current dose, moving up can sometimes cause a bit of nausea or an upset stomach. Our team at SheMed will be here to support you and give you tips on how to manage this.

Feeling constantly hungry, battling random cravings, or feeling like your body is “working against you” is not a personal failing. GLP-1, a key hormone that regulates appetite, fullness, and blood sugar, plays an important role in these experiences.
It is released from intestinal L-cells after eating and helps stimulate insulin, reduce glucagon, slow stomach emptying, and promote satiety, making it central to metabolic health and a major target in obesity and type 2 diabetes care.
Medications like semaglutide and tirzepatide are designed to mimic or enhance GLP-1 activity, but everyday dietary choices can also help support your body’s own GLP-1 response.
Research suggests that people with higher natural GLP-1 responses may eat around 20–30% fewer calories after a meal, highlighting how powerful this hormone can be in shaping appetite. The following article focuses on six food categories rich in specific nutrients that may naturally stimulate GLP-1 release and help you feel more satisfied throughout the day.
Six Everyday Foods That May Naturally Boost GLP-1 Levels
Supporting your body’s natural GLP-1 response may be simpler than many people expect. Below are six food categories that research has linked with GLP-1 activity, along with practical ways they are commonly included in everyday diets.
Eggs
Starting the day with eggs is a common dietary choice in many balanced eating patterns. Eggs provide a source of high-quality protein and fats, nutrients that have been studied for their potential role in supporting feelings of fullness after meals.
Some research suggests that meals higher in protein, including those containing eggs, may be associated with improved post-meal blood sugar responses and increased satiety when compared with higher-carbohydrate breakfasts. These effects are thought to involve appetite-regulating hormones such as GLP-1 and peptide YY (PYY), which play a role in signalling fullness.
Including eggs as part of breakfast may help some people feel more satisfied for longer and support overall dietary balance. As with all foods, individual responses can vary, and eggs are best consumed as part of a varied, nutritious diet.
Certain Types of Nuts
Nuts such as almonds, pistachios, and peanuts provide a combination of protein, unsaturated fats, and dietary fibre that slows gastric emptying, supports insulin sensitivity, and is associated with increased GLP-1 release and satiety.
Regular nut intake has been linked with improved glycaemic control, greater fullness, and reduced risk markers for type 2 diabetes and cardiovascular disease in clinical and epidemiological studies.
Fermentation of nut fibre by gut bacteria produces short-chain fatty acids, which can stimulate GLP-1 secretion from intestinal L-cells through dedicated receptors and related metabolic pathways.
If you are not allergic to nuts, include a small handful of nuts as a snack or add them to meals like yoghurt, salads, or porridge as a practical way to support natural GLP-1 activity and promote fullness. Evidence suggests that nut-based snacks can enhance satiety and modulate appetite-regulating hormones, including GLP-1, compared with refined-carbohydrate options.
High Fibre Grains
Whole grains such as oats, barley, and whole wheat are rich in soluble fibre, which helps smooth out post-meal rises in blood glucose and is associated with increased GLP-1 secretion and improved satiety. Soluble fibre forms a gel-like texture in the gut that slows digestion and glucose absorption, providing a more gradual stimulus for appetite-regulating hormones like GLP-1 and PYY.
A key part of this effect comes from fermentation of fibre by gut bacteria into short-chain fatty acids (SCFAs) such as acetate, propionate, and butyrate, which can activate receptors on intestinal L-cells and promote GLP-1 release. Randomised controlled trials have shown that high-fibre, oat-based meals can increase GLP-1 and PYY levels, enhance fullness, and reduce subsequent energy intake compared with low-fibre cereals.
Choosing high-fibre grains like oats and barley in place of refined grains (for example, white bread or sugary cereals) is a practical, research-supported way to support natural GLP-1 activity and appetite regulation. People with coeliac disease or gluten intolerance should select certified gluten-free whole-grain options and seek personalised dietary advice where needed.
Avocado
Avocado is a source of monounsaturated fats and soluble fibre, nutrients that are commonly associated with supporting satiety and digestive comfort. Soluble fibre can contribute to slower digestion and more gradual nutrient absorption, while unsaturated fats are often included in dietary patterns linked with metabolic health.
Some research has explored the relationship between avocado consumption and post-meal hormonal responses, including appetite-regulating hormones such as GLP-1 and peptide YY (PYY). These studies suggest that meals containing avocado may be associated with greater feelings of fullness and more stable post-meal insulin responses in some individuals.
Including avocado in meals such as salads or sandwiches may help support satiety as part of a balanced diet. Individual responses can vary, and avocado is best consumed alongside a variety of other nutrient-rich foods.
Olive Oil
Olive oil is a key component of Mediterranean-style eating patterns and is a source of monounsaturated and polyunsaturated fats. Diets that include higher proportions of unsaturated fats are commonly associated with cardiometabolic health and may influence post-meal satiety responses.
Research examining Mediterranean dietary patterns has explored their relationship with appetite-regulating hormones, including GLP-1. Some studies suggest that meals rich in unsaturated fats, such as those containing olive oil, may be associated with differences in post-meal hormonal responses and markers of glycaemic control when compared with lower-fat dietary approaches. These effects are thought to involve interactions between dietary fats and gut-derived hormones, although the exact mechanisms are still being studied.
Using olive oil in cooking or as a salad dressing can be a practical way to include unsaturated fats as part of a balanced diet. As with all dietary choices, individual responses may vary, and olive oil is best consumed in moderation alongside a variety of nutrient-rich foods.
Vegetables
Non-starchy vegetables such as Brussels sprouts, broccoli, and carrots provide dietary fibre, vitamins, and a range of plant compounds that support overall nutritional quality. Fibre-rich foods are commonly associated with digestive health and may influence feelings of fullness after meals.
Some research has examined how the order in which foods are consumed -such as eating vegetables before carbohydrate-rich foods-may affect post-meal glucose responses and appetite-related hormones, including GLP-1. These studies suggest that prioritising vegetables earlier in a meal may be associated with more gradual rises in blood glucose and differences in satiety signals, particularly in certain populations. The underlying mechanisms are still being explored and may involve interactions between dietary fibre, digestion, and gut-derived signals.
Including non-starchy vegetables as part of the first course of a meal can be a practical way to increase fibre intake and support balanced blood sugar responses as part of an overall healthy eating pattern. Individual responses may vary.
How Food May Actually Trigger GLP-1?
The secretion of GLP-1 is closely linked to nutrient sensing by L-cells in the distal small intestine and colon. Specific nutrients, including proteins, peptides, fatty acids, and monosaccharides, interact with G-protein coupled receptors and transporters on L-cells, triggering intracellular signalling cascades that culminate in GLP-1 exocytosis.
Protein ingestion, for example, leads to the generation of peptides and amino acids that bind to calcium-sensing receptors and other nutrient sensors on L-cells, directly stimulating GLP-1 release. Similarly, mono- and polyunsaturated fats activate free fatty acid receptors (FFAR1 and FFAR4), while fibre-derived SCFAs interact with FFAR2 and FFAR3 to promote GLP-1 secretion.
Overall, protein, healthy fats, and dietary fibre represent the three main dietary triggers for endogenous GLP-1 release. Their combined presence in whole, minimally processed foods accounts for the satiety-enhancing and glucose-lowering effects observed in dietary intervention studies.
Fibre and Gut Health Synergy
The interplay between dietary fibre, gut microbiota, and GLP-1 secretion exemplifies the complex synergy underlying metabolic health. Fibre that escapes digestion in the upper gastrointestinal tract is fermented by colonic bacteria, resulting in the production of SCFAs such as acetate, propionate, and butyrate. These SCFAs serve as signalling molecules that activate FFAR2 and FFAR3 on L-cells, directly inducing GLP-1 release.
This gut microbiota-mediated mechanism not only enhances GLP-1 secretion but also confers additional metabolic benefits, including improved insulin sensitivity, reduced inflammation, and maintenance of gut barrier integrity. The inclusion of high-fibre foods such as whole grains, nuts, vegetables, and legumes thus represents a cornerstone of dietary strategies aimed at boosting GLP-1 and supporting overall metabolic health.
Conclusion
Dietary patterns that include adequate protein, fibre, and unsaturated fats are commonly associated with satiety, balanced blood sugar responses, and overall metabolic health. Foods such as eggs, nuts, high-fibre grains, avocado, olive oil, and non-starchy vegetables provide a range of nutrients that have been studied for their potential association with appetite-regulating hormones, including GLP-1. These foods contribute to feelings of fullness and may support steadier post-meal glucose responses as part of a balanced diet.
Research exploring GLP-1 has primarily focused on its role in appetite regulation and glucose metabolism. While diet alone is not a treatment for metabolic conditions, nutritional approaches that prioritise whole, fibre-rich, and protein-containing foods are widely recommended to support long-term health. Individual responses can vary, and dietary strategies are most effective when tailored to personal needs, preferences, and medical guidance.
For those exploring structured weight-management support, clinically supervised programmes can help integrate nutrition, lifestyle, and medical considerations in a safe and evidence-informed way.
If you would like to learn more about medically supported weight-management options, SheMed offers personalised programmes designed to align with individual health goals. Eligibility assessment is available online to help determine whether a programme may be suitable.
