People placed on low-fat diets start preferring low-fat foods over fatty options.66 Your tongue may actually become more sensitive to fat, and the more sensitive your tongue becomes, the less butter, meat, dairy, and eggs you eat. On the flip side, if you eat too much of these foods, you may blunt your taste for fat, which can cause you to eat more calories and more fat, dairy, meat, and eggs and ultimately gain weight.67 This can all happen in just a matter of weeks.68
