Carb Smart: With GLP-1s

Balancing Carbohydrates in Your Diet

‍

‍Nearly 67% of adult women in England were classified as overweight or obese in 2021 【NHS Digital, 2019】. For many, dieting alone isn’t enough - which is why GLP-1 agonists like Wegovy and Mounjaro are changing the game. These medications help reduce appetite, increase fullness, and support fat loss 【Cummings & Overduin, 2015】. But to maximise results, understanding how to balance carbohydrates is key.

How GLP-1 Agonists Support Weight Loss

• Suppress appetite: Reduce hunger by acting on the brain’s satiety centres
• Delay stomach emptying: Keeps you fuller for longer
• Enhance insulin sensitivity: Improves blood sugar control and reduces fat storage
• Curb cravings: Especially for high-fat and sugary foods
• Support fat loss: Help preserve muscle while reducing fat 【NCBI, 2018】
  
  

Evidence: In the STEP 1 trial, semaglutide users lost 15-17% of body weight in 68 weeks, compared to minimal weight loss in placebo 【Kahn et al., 2023】.

Carbohydrates: Quality Over Quantity

Simple Carbs (limit):

• Sugary drinks, white bread, pastries
• Cause rapid blood sugar spikes and hunger crashes

Complex Carbs (prioritise):

• Whole grains (brown rice, oats)
• Legumes (beans, lentils)
• Vegetables (sweet potatoes, leafy greens)

Glycaemic Index (GI):

• High GI foods → spikes + crashes = more cravings

Low GI foods → steady energy + better weight control 【SACN, 2015】

Study Insight: Eating an extra 3.5 oz of low-quality carbs daily linked to gaining 3 lbs in 4 years, while small fibre increases cut weight gain by half 【Kahn et al., 2023】.

Practical Tips for Carbs on GLP-1

• Follow UK guidelines: ~50% of daily calories from carbs (≈267g/day for women) 【Nutrition Society】
• Distribute intake: Eat complex carbs earlier in the day for energy
• Pair carbs with protein/healthy fats: Keeps blood sugar stable
• Avoid extreme restriction: Too few carbs → fatigue, nutrient deficiencies, slowed metabolism

Stay hydrated: Drinking 500ml of water before meals can aid satiety 【Research cited in NHS Digital】

When to Seek Help

Consult a healthcare professional if:

• You’re unsure how to balance carbs with GLP-1 therapy
• You notice persistent fatigue, digestive issues, or blood sugar fluctuations
• You want a personalised diet plan tailored to your activity level and health needs
