Yup, I said it.
If your metabolism is such that eating excess dietary fat slows it down, doing paleo could be detrimental to your goals.
Let's keep it on the real here. Most personal trainers do NOT do a paleo diet, and in fact prefer either a cyclical diet or one in which fat intake is kept at a minimum and they instruct their customers to do the same!
My own personal experience is that a higher carb, lower fat diet worked to shed the stubborn body fat. And it is my explicit belief that the only way to shed serious pounds (that is, six pack pounds) on a paleo diet is to do EXTREMELY HEAVY weight training!
But by the above logic, you can gain results on ANY DIET! That's right. ANY diet! And I have seen countless examples of guys on extremely high carb diets losing pound after pound of body fat, and gaining pound after pound in muscle.
What is spoken of on this website mostly is scientific speculation, not macroscopic results. yes, there are those who see results on paleo diets but these are DEFINITELY in the minority.
Most people who try, or who WOULD try a high fat and extremely low carb diet would fail due to energy in being greater than energy out. Why? Because most people who dispense with carbs entirely HAVE NO ENERGY OUTPUT!
Adaptation nothing! Tried it, never adapted. Carbs are needed for energy, period unless you are a genetic exception to the general rule.
Bottom line is this, moderate fat is fine, HIGH FAT isn't, at least for the majority of the population.
Go ahead, negative vote me, I don't care.
