Your friends on low fat diets are obviously fat because they consume too many calories.If you eat a diet that has only 10% of it's calories from fat, you will be hungry all the time and get fat because you overeat. You should have at least 20% of your calories from fat but no more than 30%.
Our ancestors a million years ago probably did'nt have meat every day
.Maybe different people do better on different diets because of blood type and other genetic factors. While Asains ,Mexicans and Central americans eat grain , they don't eat much wheat so maybe wheat is worse than rice etc.I can't believe that a diet of meat eggs and fat provides adequate nutrition Bex.
