Carbohydrates
We store carbohydrates as glycogen in our liver (120 grams) and muscles (400 grams). You can think of the liver and muscles as limited, short-term gas (energy) tanks. When the gas tank is full, excess fuel (carbohydrates) gets stored as fat, which is our long-term energy storage.
Body composition
The scale and BMI are ineffective tools for gauging your overall body composition, meaning they don’t tell you enough to determine if you are at a healthy weight.
