The biggest nutritional mistake people can make is getting rid of all the fat in their diets for weight loss. Not all fats are bad, and some are required for good health. This is surprising when you consider some basic facts about fat. It is a fact that 1g of fat contains 9 calories, compare with 4 calories in 1g of carbohydrate or protein. And it is also a fact that the body stores energy from fat more efficiently than from protein and carbohydrates.
Monounsaturated and polyunsaturated fats may actually help to keep blood sugar and insulin levels burning instead of fat storage. New England Journal of Medicine and elsewhere have found that the Atkins diet, rich in protein and saturated fat, may promote more weight loss and better cholesterol levels than high carbohydrate, low fat diets.
It appears that, rather than clogging arteries and packing on the pounds, the monounsaturated and polyunsaturated fats improve cholesterol ratios and help with weight loss. Monounsaturated fats have been shown to help to raise levels of high density lipoprotein (HDL or ‘good’) cholesterol and lower levels of low density lipoprotein (LDL or ‘bad’) cholesterol. They also seem to be involve in the controlling of hunger and burning of fat.
Experts agree that the Trans fats in many processed and fried foods are particularly bad for you and your health. Most also agree that the saturated fats in animal products are less beneficial than unsaturated fats. Researchers now believe that monounsaturated and polyunsaturated fats are essential to good health. These good fat foods are good for your heart and waistline.
