Final answer:
The approach to weight loss with the highest rate of long-term success is typically Low-calorie, low-fat diets combined with exercise. Therefore, the correct option is B.
Step-by-step explanation:
This strategy incorporates regular physical exercise with a balanced diet that is lower in fat and calories, with an emphasis on sustainable lifestyle modifications. These all-encompassing approaches encourage slow, steady weight loss, increasing the likelihood that people will keep the weight off in the long run.
Over-the-counter diet pills, anti-obesity medications, and commercial weight loss programmes that promise quick weight loss may provide immediate benefits, but they frequently fall short of providing the lifestyle integration and sustainability needed for long-term success.
Exercise and a nutritious diet together address all facets of weight management and promote general wellbeing.
Therefore, the correct option is B.
