🔑Calories model: The belief that weight gain is solely determined by calories consumed and calories burned.
🔑Hormonal model: The idea that food not only provides energy but also elicits different hormonal responses that affect weight gain.
🔑Metabolic adaptation: When calorie intake is reduced, the body adapts by lowering the metabolic rate, making weight loss more challenging.
🔑Exercise and hunger: Increased exercise can lead to an increase in hunger, potentially offsetting the calorie deficit created by exercise.
🔑Energy gap: Moderate exercise may not be sufficient to create a significant calorie deficit, making weight loss difficult.
