Forms of a low-fat diet have been the mainstay of government nutritional guidelines around the world for years. Low fat diets often pop up in famous weight management plans like Slimming World and Weight Watchers, which are in essence calorie controlled diets, which limit fatty foods primarily as they are more calorific in nature.
A low fat diet encourages plenty of fruits and vegetables, alongside plenty of wholegrains. These foods are generally nutrient dense and help easily meet nutrient requirements and fibre goals. Fat also in comparison to protein and carbohydrates has a higher calorie density attached, therefore a high fat food is often higher in calories. Both low fat diets and higher fat diets seems to work equally well, with neither outperforming the other. The thing that makes the biggest difference is someone’s preference and therefore the increase in likelihood of them remaining on the diet.
