There's enough anecdotal evidence to stir doubt among the medical community that eating "low fat" is actually having the opposite effect.
I know enough people who have dropped carbs and eat "the caveman diet" that it convinced me that sugar is dangerous and fat is not.
Why do you think farmers feed grain and potatoes to animals?
(Hint: it ain't to make 'em skinny)
My friend and I have a chuckle every morning in the cafateria. The most grossly obese are the ones that order the low fat muffins. It is sad actually.
Meat, fish, eggs, nuts, and low glycemic index vegetables are the composition of my diet. I have lost 30 pounds in 5 months and do not seem to have lost any muscle.
On the negative side, I think it was Cassius who was described as having a "lean and hungry look." The diet has filed a bit off my trigger. Not much pull is required.
