Macros do not significantly affect metabolic rate. Exercise does though.
Glycogen (carbs) is the preferred fuel for almost every cell in our bodies. All the fat & protein we eat that ends up used as metabolic fuel will first be converted into carbs. Now granted the thermal effect of these macros are different (it takes more energy to turn protein into fuel than it does to convert table sugar) but the idea that "you need to eat fat to burn fat" is a myth.
- cschmidt 12y agoMany people think that ketones are the preferred fuel for every cell in our bodies.
- jp555 12y agoeveryone is entitled to their own beliefs, but not their own facts. Glycogen is the preferred fuel, which are giant chains of glucose (carb) molecules. I've done keto, and you have to be very careful as even a small amount of carbs will quickly shift the body out of ketosis and back into using glycogen. Doesn't the fact that ketosis is so fragile indicate to you that it's not the preferred state? Homeostasis reigns, and the body gets away from ketosis whenever it can. It's an extreme state.
- tomp 12y agoDo they? Everything I've read about keto diet is that it will make you less "short-term energized" - you're lacking glycogen, i.e. you won't be able to sprint as much.
