Fad diet

A fad diet is a type of diet that becomes really popular and everyone wants to try it out. People think it's a quick fix to lose weight or get healthy. Fad diets usually have weird rules that are not easy to follow, and they promise quick results, but they're not healthy in the long run. Imagine your mom made you eat only carrots for a week. Sure, you might lose weight quickly, but you would never want to eat carrots again, and it wouldn't give you all the energy and nutrients you need to grow big and strong. Fad diets can be like that, but with different foods or different rules. Some fad diets say you shouldn't eat any carbs, just protein and fat. Other fad diets tell you to only eat certain foods like grapefruits or smoothies. These diets usually don't work, and they can even be harmful to your body. It's better to eat a balanced diet that includes lots of different foods, like fruits and vegetables, whole grains, lean protein, and healthy fats.
