It is a fact that low fat diets do not help with weight loss. The consumption of more meat and a little more fat than previously, especially if you've been consuming a low fat diet, can help you feel fuller longer and therefore eating less frequently to allow the body to find the fat stores to use the fat for energy resulting in fat loss.
Doing some exercise, like walking for a start can help. Caffeine in moderation can also help as an appetite suppressant.
