It's pretty obvious that altering ones diet can have profound effects. But a scientific approach to diet is a far safer approach. Ever tried to lower your bad cholesterol?
So a group of friends who are data obsessed tried keto after another group of friends raved on about it like it was a sign from above. The group that took a scientific approach getting blood work before and after noticed their LDLs shoot through the roof. Before keto: LDL 70. After 4 months on keto LDL 190. That's well above the Sutter health recommended LDL 120. Even 120 is well above what heart surgeons recommend to avoid cholesterol in your arteries: LDL below 70.
The other group that raved on about keto claimed to have done blood work but never shared the numbers. They said they felt great etc.. no st, the brain craves fats. You will feel better. You can triple your fish oil intake and experience some of that natural high for those daring.
Anyways some food for thought.
