To lose weight without feeling hungry all the time, which is the easiest method, I found eating three small meals and two small snacks (like an apple, popcorn or handful of almonds) helped me healthfully drop weight. I also found having one daily single serving of a sweet (piece of pie, candy bar, etc) contributed to my body automatically slimming to my optimum weight that was right for my age and height. This way my body did not have cravings for I still in moderation ate what I liked.
Most overweight is caused by bad eating habits like eating more than a single serving of something; especially comfort foods like French Fries. I know people who found if they ate one single serving for each food item they ate in their meals this contributed to weight loss. Healthy eating habits and dining organically can also contribute to weight loss. Salads like a Chef Salad are a meal; less fattening than a hamburger meal.
Non-organic foods may have food additives like a chemical taste enhancement to make people want to eat the food product again (or more) - per 60 Minutes, aired beginning of September 2012. It is further recommend to discuss a weight loss program with your regular physician or a certified nutritionist to make certain the chosen diet is perfect for your health (advice from the official Mayo Clinic website).
