What are Fats in Human Body?

High-Fat foods for keto diet are the fundamental ingredients of Keto diets. When we use the word “Keto diet” it means low-in-carbohydrates, moderate-in-protein, and high-in-fats. The fats are also nutrients just like carbohydrates and protein.

Fats play a vital role to protect brain functioning and heart-healthy by providing HDL cholesterol. Furthermore, high-fat foods keep HDL level high and LDL level very low which protects us from various heart diseases and strokes.

From an earlier era, unless proved by medical science nowadays, we’ve been told that fats aren’t good for health. Eating high-fat foods raises cholesterol levels and causes various health issues i.e. health diseases, weight gain, high blood pressure, and cholesterol level and strokes. But today medical science proved that fats have both aspects i.e. good and bad, depending on the types of fats.
