Final Answer : D, Explanation :  Fat tissue can be maintained by fewer calories than can other body tissues, so John may need to reduce calorie intake even further to lose weight. Additionally, while a low-sugar, low-carbohydrate diet can be effective for some individuals, it may not be sustainable or effective for everyone. Maintaining a consistent calorie deficit through a healthy and balanced diet and regular exercise is often the most effective way to achieve and maintain weight loss.
