Answer:
The best answer is "C"
Step-by-step explanation:
Restricting food intake normally increases energy expenditure.
When people who are obese decrease the amount of food they eat, metabolic responses vary greatly, with a 'thrifty' metabolism possibly contributing to less weight lost but if the food intake is restricted there will be changes in body size and body composition. In addition, energy restriction induces an adaptive reduction of energy expenditure through a lowering of tissue metabolism and a reduction of body movement.
