Answer:
Limiting calorie intake and increasing the energy needs.
Step-by-step explanation:
The energy that is required to carry out the various metabolic process of the body is gained by the food we intake.
The macromolecules that provides energy are carbohydrates, fats and proteins.
The energy is first derived by carbohydrates then fats and at last the proteins of the body is used.
If one will increase the requirement of energy without calorie intake, it will lead to breakdown of fat molecules to provide energy as all the carbohydrates are used.
