A Closer Look at Calories
What Are They?
A unit or measurement of energy
Basal Metabolic Rate
The number of calories you need to sustain basic life activities
3,500 calories= 1 pound of fat
Calorie Surplus
You consume more calories than your body burns a day. Your body stores these calories for another day when calories are scarce.
Calorie Deficit
You consume less calories than your body burns a day. Your body will use calories from your fat cells and glycogen for energy.
Carbohydrate Storage:
The extra calories you consume from carbohydrates are converted into glycogen and stored in your muscles and liver.
Fat Storage:
Once glycogen stores are full, your body stores excess calories in your fat cells. You do not gain fat cells, they just shrink or grow.
