Finding the diet that fits you best can make all the difference to your health and weight control goals. To work on your weight, first try asking yourself: What kinds of foods are the hardest for me to give up? What’s my optimal, healthiest weight? Diets aren’t just about losing weight, however. Changing what you eat can also support the treatment of many types of health conditions.

While advocates say that the following diets may help control or prevent certain conditions, these claims may or may not be supported by controlled clinical studies or published scientific articles. For more complete information, go to the full article on the health concern or diet that interests you. You should always consult your doctor before changing your treatment (including diet) for any health concern.

Whatever your goals, if you aren’t sure which diets best fits your self-care needs, this list can be a place to start.
