Low-fat diet

Low-fat diets are intended to reduce the occurrence of conditions such as heart disease and obesity.

[2] According to the National Academies Press, a high-fat diet can contain "unacceptably high" amounts of saturated fat, even if saturated fats from animal products and tropical oils are avoided.

For this reason, the Institute of Medicine recommends consuming no more than 35% of calories from fat.

[1][4] A scientific panel for the Endocrine Society stated that "when calorie intake is held constant [...] body-fat accumulation does not appear to be affected by even very pronounced changes in the amount of fat vs carbohydrate in the diet.

[5] Saturated fat has been shown to raise total and LDL cholesterol in a large number of studies[6] and has also been correlated with a higher risk of heart disease.
