--

Your "healthy" low-carb diet might be secretly working against you by elevating your stress hormones and slowing your metabolism.

Beyond the immediate effects of energy crashes and stalled weight loss, emerging research reveals a deeper, more concerning connection between carb restriction, stress hormones, and metabolic health.

If you've been experiencing (or want to avoid) energy crashes, stalled fat loss, or feeling unusually stressed, there could be a physiological connection between your carbohydrate intake and cortisol levels that's sabotaging your results.

This episode reveals the research-backed connection between low-carb diets and elevated cortisol, and how this hormonal response can trigger a cascade of metabolic effects that make fat loss harder, not easier.

Discover the optimal carb approach that supports your metabolism, thyroid function, and training performance while keeping stress hormones in check.

Main Takeaways:

• Low-carb diets trigger a stress response that elevates cortisol, even without a calorie deficit
• Chronically elevated cortisol can suppress hormones and slow your metabolic rate
• Carb timing can help manage cortisol levels
• Carbs should be reintroduced gradually if you've been on a very low-carb diet
