Final answer:

The weight-set-point hypothesis explains why it is difficult for individuals dieting to lose weight when the set point is 'stuck' at a higher level. The body defends this higher set point through compensatory changes in energy intake and expenditure, making weight loss challenging.


Explanation:

The weight-set-point hypothesis suggests that when too many fat cells are present due to earlier weight gain, the set point may get 'stuck' at a higher level. This can make it challenging for individuals dieting to lose weight because the body tends to defend this higher weight set point through compensatory changes in energy intake and expenditure.

During weight loss efforts, the body perceives the decreased fat stores as a threat to survival and responds by lowering basal metabolic rate to conserve energy. Additionally, physical activity may decrease as there is less mass to move, leading to fewer calories burned, further hindering weight loss progress.
