As with all diets, find out if it works for you.
Me, personally, I die on this diet. But, I am seemingly rare body type.

What I have learned from watching friends on this diet is that it works really well. The number one important thing is consuming good fats. McDs fats will kill you.

Your kidneys are made up almost entirely of fat. And your body cannot tell if it is a good fat or a bad fat. Your kidney gets slowly replaced by the fats you consume. So, bad fat equals bad blood cleansing and leads to poor health.

Also, on a high fat, low carb diet, do not forget that you are going to be eating lots of vegetables.
