So I began wondering, there is a lot of information about the longevity effects of CR and Protein Restriction to an extent. However, what is the best age to start this? I am 18 years of age and I was pondering whether it is really wise to start CR and protein restriction (PR) at this age or wait a few years. It would be difficult to integrate such a regimen at my age but if it means it would be beneficial, then I will be willing to start.
Also, is higher protein detrimental at my age? This PR is a real conundrum. 
Thanks! 
It probably depends on your own circumstances. If you are an overweight diabetic 18 year old, maybe it would make sense. For the average 18 year old, I think that is a bit too young. I'd wait until 24-26, after your development tapers off.
This does make sense, development does continue into the mid twenties so I understand what you're saying, thanks. Just for the clarify, I am a healthy, non-diabetic and of a healthy weight haha.
At this time it is best for you to eat as much protein and fat as possible. The brain keeps changing until 21, so you need enough fatty acids and protein to help it through this stage. Protein will also help you with any growth spurt that may come to you. Okinawans, the people who restrict protein heavily, are around 4'11 in height. This is one of the reasons protein restriction does not work. Carbohydrate restriction is safe at all ages. It will help you live longer without the dangers of protein restriction. If you're worried about protein just eat some gelatin and eat more fat than protein. Beware of those who foolishly follow protein restriction without doing research beyond the first result of a pubmed search. Think for yourself and smartly.
Thanks for this! But I feel that PR does have a lot going for it and it does tend to work around the globe. Epidemiological studies from many different parts of the world mostly suggest that limiting animal protein intake is beneficial and reduces cancer rates. I do agree about the fat intake, fat is so beneficial! I do have the majority of my caloric intake from healthy non-animal fat sources.
