Why does eating fast food and snacks often result in weight gain?
The reason for this is that fast food and snacks very often consist of a lot of simple sugar and trans fatty acids. These two ingredients are the two major thickeners. Simple sugar does metabolize in fat more easily than long-chain carbohydrates or protein. Trans fatty acids have twice as many calories as carbohydrates or protein and are simply unhealthy. For this reason you should avoid fast food and snacks altogether, or reduce them to a minimum. Here are some examples of food products which contain a lot of simple sugar and fat: crackers, candies, baked goods, cookies, snack foods, fried foods, salad dressings, many processed foods, sweets, biscuits, cakes, pastries, puddings, ice cream.
