'What is the best explanation for the finding that when people overeat the observed weight gain is generally lower than the theoretical weight gain calculated based on the cumulative energy surplus? The calculation of the theoretical weight gain is based on incorrect assumptions about the energy value of bodyfat As food intake increases people automatically increase their activity pattern As food intake increases larger portion of the energy ingested is undigested and leaves the body in the stools As people become heavier, their energy expenditure increases as well due to increases basal metabolic rate and increased energy cost of physical activity'

Failure to communicate. Leptin inhibits eating and is secreted in amounts in direct proportion to body fat. Moreover, obese people have normal amounts of leptin and leptin receptor. Why, then, do people become obese?
3. People expend energy continuously and eat periodically to refuel. Ideally, their energy intakes cover their energy expenditure without too much excess. Energy intake is stored as fat, and stored fat is used for energy between meals. People who consume more food energy than they expend store the surplus as body fat. To reduce body fat, they need to expend more energy than they take in from food. To manage weight, it is important to understand the body weight components and fat cell development and metabolism a. Explain body weight components and variations in men and women bodies (2) b. Describe how body fat develops and suggest some reason why it is difficult for obese person to maintain weight loss (2 + 2)
