I hear a lot about the benefits of a low calorie diet, but I love training hard in the gym and on the track. I want to extend my life and have good health, and I know that eating a low calorie diet(1600-200k for me) will do that, but I also want to continue to make training part of my life. Can I have both? Is this an example of 'trying to have you cake and eating it too'?
Also I want to note that if I go through with the low calorie diet I'm also going to significantly reduce the amount of protein I get, probably to 50-70g(I'm at about 190g a day now). I want to know if it's possible to gain muscle or stay fit(fit not in the T-Nation sense of the word, but fit in the wider cultures sense of the word) with 50g of protein a day.
Lastly,I would rather this not turn into a debate about the efficacy of a low calorie diet for longevity and general health.
