Fad diets may seem like an easy way to lose weight. The problem is that many fad diets often ask you to give up one or more food groups. This might be easy to do for a few days. But it’s not easy, or healthy, to cut out a food group for long periods of time. A healthy diet is not about excluding food groups. It’s more about making healthy food choices. This includes eating a variety of foods in moderate portions. When you focus on whole foods and foods from all the food groups, you’re more likely to stick with your eating plan for the long run.
