But there is another meaning of this word. Diet can also refer to the food and drink a person consumes daily and the mental and physical circumstances connected to eating. Nutrition involves more than simply eating a “good” diet—it is about nourishment on every level. It involves relationships with family, friends, nature (the environment), our bodies, our community, and the world.
That’s why many health experts are concerned about people on the keto diet, especially those who try it without the guidance of a doctor or nutritionist. Doctors say that high-fat diets like this one may raise cholesterol levels, and some studies suggest that they increase the risk of diabetes. Some have even called it a “cardiologist’s nightmare.”
Make sure that the diet has been studied extensively for safety — and discuss any changes with your physician or registered dietitian before beginning a new diet. (If you don’t have a dietitian, find one in your area at the Academy of Nutrition and Dietetics website.) And do a self-check to ensure the diet fits with your own values and preferences.
It seems like an easy diet win: Skip breakfast and you'll lose weight. Yet many studies show the opposite can be true. Not eating breakfast can make you hungry later, leading to too much nibbling and binge eating at lunch and dinner. To lose weight -- and keep it off -- always make time for a healthy morning meal, like high-fiber cereal, low-fat milk, and fruit.
