Answer: (B)

Verified step by step guidance

1. Understand the concept of weight cycling: Weight cycling, also known as 'yo-yo dieting,' refers to repeated cycles of weight loss and weight gain. It often occurs due to physiological and behavioral factors.
2. Analyze the body's response to dieting: When calorie intake is reduced or exercise is increased without proper nutritional balance, the body may slow down its metabolism to conserve energy. This can lead to weight regain when normal eating resumes.
3. Consider the role of fast food consumption: The availability and overconsumption of calorie-dense, nutrient-poor fast foods can contribute to weight gain after a period of weight loss, especially if healthy eating habits are not maintained.
4. Examine genetic factors: Certain genetic variants, such as the FTO gene, have been linked to weight regulation and may predispose individuals to fluctuations in weight. This can make maintaining a stable weight more challenging.
5. Connect the factors: Weight cycling is often a result of a combination of slowed metabolism, behavioral patterns (like overeating fast food), and genetic predispositions. Addressing these factors holistically is key to breaking the cycle.
