A low fat weight loss program recommends low fat or no fat foods. The underlying principle behind this diet is that reducing fat intake results in lasting weight loss.
We need certain fats (essential fatty acids), so a low-fat diet doesn’t mean a no-fat diet. Also, just because a food is low-fat doesn’t mean it’s healthy or less fattening. It may be high in sugar which is not good for your health or weight. So whenever possible, choose low fat brands that are also low in sugar.
