Eating is for nutrition. This study analyzes weight loss, but not nutrition. I would be interested in which diet meant people had no vitamin or mineral deficiencies. Many people who eat low carbohydrate eat few vegetables and fruit because of their carbo content. I have a difficult time believing that is healthy. The extreme, of course, is the Ketogenic diet.
Talk about heart ache: high blood pressure stresses arteries, and can make you more susceptible to heart disease. To eat to lower your blood pressure, you just need to focus on heart-healthy bites. The American Heart Association recommends loading up on fruits, veggies, whole grains, low- or non-fat dairy, beans, lean meats, and fish. Bonus: no one's ever gotten fat eating more kale and beans.
