Answer:
The answer is set-point theory.
Explanation:
This theory, as the paragraph explains, states that our body weights are unikely to change unless there is an extreme change in diet or exercising habits. This way, our "set-point" resists any changes and compensates them with a difference in the energy intake and expenditure.
However, this theory has not received much support in the scientific community, as no metabolic changes were observed in subjects who suffered a considerable weight-loss.
