Low-fat diets can be very misleading because they are sending people the wrong message. The label, “low-fat” urges people to stray away from all fats completely, including the good fats that are needed to prevent illness such as heart disease. Also, when food producers take the fat out of a food they have to replace it with something else; which is usually a refined carbohydrate from sugar. These refined carbs can cause a spike in blood sugar and insulin levels because they are digested very fast. Hunger is a result of these high levels dropping down again. The hunger leads to overeating and weight gain.
