No, skipping meals is not a good idea. It will lead to more hunger and lead to overeating whenever you eat next. The number of meals in a day does not affect weight loss. So skipping a meal ideally does not. But it is important to follow a routine and stick to it. The routine can be just 2 meals also in a day of you must have good control over your hunger. If you are unable to control hunger then have healthy mid day snacks.
