Final answer:
A person who has failed restrictive dieting can try making sustainable, lifelong changes to their eating habits and incorporating regular exercise.
Step-by-step explanation:
When someone has failed restrictive dieting, another strategy they can try is to focus on making sustainable, lifelong changes to their eating habits rather than following a strict, short-term diet. This approach involves changing the way they think about food and making careful choices about what they eat. Instead of crash dieting or following fad diets, they can opt for a long-term, balanced eating plan that includes a variety of nutritious foods. Physical activity, such as regular exercise, can also be incorporated into their lifestyle to support weight management.
