Fructose promotes triglycerides and the formation of these fatty acids, and is linked to heart disease. The amount of fructose in your diet affects your body weight. The amount of sugar in your diet also affects your body weight. These are all factors that influence the type of fatty acids in your body that are involved in fat metabolism and heart disease. For example, the amount of fructose affects how quickly you start to store fat in your body. So, if you eat enough refined sugars to get more saturated fat, you will have more of the "carbohydrate" in your body. So, to get more saturated fat, you would need to eat more fructose. So, if you eat too much refined sugar and no fiber, your body will be less able to store energy.
