While I'm no physician, neither will be any others who answer. The prevailing wisdom of the day is that carbohydrate intake should be greatly reduced, and that fats and protein should be eaten instead. It sounds counter-intuitive, but a high fat diet never equated into someone gaining weight unless there were other circumstances involved which were the deciding factors.
Hi Wesman Todd Shaw! Thank you for your speedy response, however can you explain what you mean by other circumstances as it relates to a high fat diet. I'm assuming you are referring to clean eating and an overall healthy life-style.
Yeah - by other circumstances I mean leading a lifestyle where you don't move around much. I was always thin, but for a time I didn't have much to do, I just sat around all day, and ate a lot of pizza. I put on a lot of weight fast.
Muscle 'growth' occurs from stressing muscles at a greater rate than they are accustomed to. Note: That changes with time, even though the time may be months or years. That means exercise with an emphasis on some kind of weight training for different muscle groups. The body converts proteins to muscle. So, a higher than normal consumption of proteins is suggested during that process of stressing the muscles.
