Do carbs make you fat?
Are spikes in blood sugar and insulin a problem for health or weight loss?
Maybe you've been cutting carbs or tried keto or carnivore, yet your strength training progress has stalled, your recovery feels sluggish, and you're still not seeing the body composition results you want.
The problem isn't your discipline. It's a fundamental misunderstanding of what insulin actually does (especially if you lift weights).
Insulin is not a "fat-storage hormone" but a nutrient-partitioning hormone whose effects depend entirely on context: your training status, muscle mass, and energy balance.
Learn how resistance training changes the way your body handles carbs, why lifters over 40 actually benefit from strategic insulin spikes, and how muscle tissue acts as a "sink" for glucose that determines where your nutrients go.
It's not about eating unlimited carbs but understanding why carb tolerance is built through strength training and how to use that to your advantage, and to stop fearing spikes in blood sugar.
Whether you want body recomp, trying to build muscle while losing fat, or wondering why your low-carb diet isn't working despite consistent strength training, this episode gives you an evidence-based framework to rethink your nutrition strategy.
Plus, get a simple post-workout protocol that can improve your next-day training performance.
