The phrase "fat intake" refers to the amount and type of fat consumed in one's diet. Fats are an essential macronutrient that provide energy, support cell growth and development, and help with the absorption of certain vitamins. The body needs a balance of different types of fats: saturated, unsaturated, and trans fats. A healthy fat intake is important for overall well-being, but too much can lead to weight gain and other health issues.
