How do high-carb and low-carb diets affect continuous glucose monitoring in athletes? 🧐
And can these trends influence our diet?
Low-Versus High-Carbohydrate Isocaloric Diets on Continuous Glucose Monitoring Metrics in Healthy Trained Cyclists: A Randomized Crossover Trial
Study Details
This new study recruited 15 trained male cyclists to complete 2 x 7-day diets…
1️⃣ High-carb (> 5 g/kg carbs per day)
2️⃣ Low-carb (< 26% of total energy)
Glucose data was continuously across each diet using CGM technology 🩸
Key Findings
The low-carb diet led to significantly reduced…
🩸Mean glucose levels
📈 Glycaemic variability
Mean glucose values were significantly higher during exercise vs wake and night phases irrespective of diet 🚴♂️
Exercise intensity was positively associated with higher glucose concentrations, also irrespective of diet 🫀
Nocturnal glycemia was significantly lower after exercise days…
…suggesting an influence of prior physical activity on overnight glucose regulation 💤
Substantial interindividual variability in glucose responses was observed, highlighting the necessity of personalised dietary strategies for athletes🚨
Conclusion
Dietary carbohydrate content and exercise timing significantly influences glucose response‼️
What does this mean long term? Difficult to say at present. This will need to be studied 🔍
