Summary
Your glucose response to foods is highly individual - some spike to potatoes, others to grapes - making CGM data essential for personalized nutrition. Post-meal brisk walks (15-20 min), soleus pushups, and exercise snacks effectively blunt glucose spikes. If you have muscle insulin resistance, morning workouts improve next-day glucose control better than evening sessions.
Key Points
- People spike blood glucose differently to identical foods—some are "potato spikers" while others spike to grapes, making personalized measurement via CGMs essential
- Post-meal brisk walks (15-20 minutes), soleus pushups, and exercise snacks effectively reduce glucose spikes without requiring full workout sessions
- Type 2 diabetes isn't monolithic—muscle insulin resistance, beta cell defects, and incretin defects require different lifestyle and drug interventions
- People with muscle insulin resistance benefit from morning exercise for next-day glucose control, contrary to general recommendations
- GLP-1 drugs work best when combined with consistent resistance training to preserve muscle mass during weight loss
- Consistent bedtimes, eating earlier in the day, and post-dinner walks correlate with better glucose regulation and sleep quality
- Individual responses to different fiber types vary dramatically; some experience inflammation while others see decreased inflammation
Key Moments
A 20-min walk after eating blunts glucose spikes, plus the soleus push-up trick
A brisk 20-minute post-meal walk visibly flattens glucose spikes on a CGM.
"You will spike your glucose, but if you take a brisk 20-minute walk, you can just see that spike is much, much less."
Resistance training may be better than cardio for blood glucose in insulin-resistant people
For people with muscle insulin resistance, resistance training may be more effective than cardiovascular exercise for improving blood glucose.
"For many people, in particular people with muscle insulin resistance, doing resistance training would be preferable to doing cardiovascular training for blood glucose."
Strength training on GLP-1 drugs prevents muscle mass loss
People on GLP-1 drugs who do resistance training can significantly reduce muscle mass loss. Dr.
"It's pretty clear that people do do strength training. Again, larger studies would be nice, but it's pretty clear they can reduce their muscle mass loss."
