Episode notes
Fat Burning vs. Fat Loss
- Burning fat doesn't equate to losing fat; energy balance determines fat loss.
- High-carb diets may store less fat because carbs are primarily oxidized or stored as glycogen, not fat.
Carbs and Fat Storage
- A metabolic tracer study revealed that under 2% of stored body fat comes from carbs.
- A meta-analysis of 20 calorie and protein-matched diets found no significant fat loss differences between high-carb and high-fat diets.
Short-Term vs. Long-Term Responses
- Be cautious of equating short-term responses with long-term outcomes, especially with continuous glucose monitors.
- Short-term insulin spikes may actually improve long-term insulin sensitivity.
