Is A Calorie Just A Calorie?

Does it really matter what you eat as long as you're not over-consuming calories?

Like...what's the difference between eating 100 calories of pizza and 100 calories of spinach? It's the same amount of calories...

GREAT QUESTION! I'll tell you:

Some topics include:

> How metabolism works and what the energy balance equation is

> How different foods are metabolized and used by the body

> How you can use the energy balance equation to lose weight or gain weight
