In the 1990s, it seemed as if every second product in the grocery store from low-fat yogurt to low-fat Oreo cookies, were proof that fat was little more than a tasty, bad-for-you four letter word. Fast forward to 2001 and an eight year study funded by the National Heart, Lung and Blood Institute of nearly 50,000 women found that their lives did not improve all that much from eating a low fat diet. They had not lost weight and they did not appear to lower their risk of heart disease. Another study conducted at the Boston Children’s hospital in 2012 analyzed the possible benefits of the low-fat diet for weight loss and found that restricted dietary fat intake slowed metabolism and showed a link to insulin resistance.
