Adam wants to decrease his current weight, so he should? a. consume the same number of calories as he burns b. decrease his caloric intake so it is less than the calories he burns c. eat foods from only one food group d. increase his caloric intake so it is slightly higher than his caloric output

B. decrease his caloric intake so it is less than the calories he burns

Explanation:

A calorie is the amount of heat required to raise the temperature of a gram of water by 1°C.

Our bodies require a certain number of calories for us to sustain ourselves. However, if we consume more calories than we are using then this leads to the calories being stored in the form of glycogen or fat.

So, Adam needs to consume a lower number of calories so that he can burn the excess away.
