Too much food is too much food.
Some people do a good job eating a balanced and nutritious diet of whole grains, beans, veggies, lean meats and dairy, and fresh fruit. They may even limit added sugars and salt. But they will gain weight when they eat more than they expend.
People with bad diets are rarely surprised when they gain weight. Those who gain weight when eating well are understandably disappointed. If you are among these folks, remember that even clean food should be eaten in limited quantities.
There is no way around it — too much of a good thing is still bad.
