There are quite a few things in the above so I won't touch on them all. Though, I must ask...what is your goal? My belief is that nearly everything in how someone eats, worksout and approaches fitness and health should be decided AFTER they understand what their goal is. Nearly all the studies above seem to have no idea what they are actually testing (the goal). Right now I am an amateur powerlifter and bodybuilder. I play sports like hockey, basketball and flag football. In the past I did triathlons and ultramarathons with friends. Do you think I approach the different phases in my life EVEN REMOTELY the same in terms of diet and exercise? So what is your goal? I'll provide a quick handy guide for some I read above. Trying to maximize your years on this earth? Only known way is to calorie restrict. Like extreme calorie restrict. Say, around 1000-1200 cals a day. Trying to maximize athletic performance in power sports (hockey, football, basketball, baseball etc)? Sprints+heavy weights for a workout. Carb cycling for food (high carb days post working out, low carb days when you don't work out). Trying to maximize athletic performance in enduro sports (distance cycling, distance running)? Know your carb maintenance level, eat for that + protein and lower(ish) fat (fat + carbs leads to weight gain almost universally. So, if you NEED to eat carbs as your main source of fuel, you'll need to lower fat if you don't track your carb intake very closely). * *Note: there are plenty of people that perform enduro sports on VLC (very low carb) and use fat as their fuel. However, I haven't found studies on this yet so I don't recommend it wholesale. If someone wants to try it and can work through the re-acclimation period in their body, give it a shot. I can go on, but I need to know what people have in terms of goals. I personally wasted too many years middling around without knowing what I actually wanted to achieve. I know others do as well. Know your goals, then you can set your approach to achieving those goals....persist and you'll hit 'em!

>Trying to maximize your years on this earth? Only known way is to calorie restrict. Like extreme calorie restrict. Say, around 1000-1200 cals a day. Hardcore males doing CR for health and longevity, pushing it as far a they can go, average about 1700 - 1900 a day. At 6+ foot and 120 pounds. 5 foot female might hit 1100 or 1200, sure. Keep in mind that's an average though. If you cheat once a week or two weeks you could easily eat a 1200 calorie diet on the other six days and have it work out the same.

  > Hardcore males doing CR for health and longevity, pushing it as far a they can go, average about 1700 - 1900 a day. At 6+ foot and 120 pounds Picking a calorie calculator at random on the internet seems to suggest otherwise. http://www.freedieting.com/tools/calorie_calculator.htm http://www.freedieting.com/tools/calorie_calculator.htm I put in 6'0", 120lb male, age 30 and just looking for basal metabolic rate gives 1500cals. Sedentary gives 1850cals. I've read elsewhere (can't find source) that most CR advocates are recommending AT LEAST 20% reduction in cals to actually qualify as CR, some saying 30%-40% are more appropriate. Those numbers from above cals are 1200 and 1480. If using 30% reduction they are 1050 and 1295. There is emerging evidence that while CR is effective, an alternate approach that is less extreme could also be just as effective: intermittent fasting[1]. I believe the IF approach warrants more research, but I'm doing it anyway b/c it also aligns with my current goals for powerlifting and bodybuilding. Hoping the research pans out in the longevity department as it will be a bonus ;) [1] - http://en.wikipedia.org/wiki/Calorie_restriction#Intermittent_fasting_as_an_alternative_approach http://en.wikipedia.org/wiki/Calorie_restriction#Intermitten...

    >I put in 6'0", 120lb male, age 30 and just looking for basal metabolic rate gives 1500cals. Sedentary gives 1850cals. I've spent a bit of time researching CR and I can tell you those numbers are way too low. As an anecdote, one of the most dedicated and extreme practitioners in the world is at about 6 foot 120 pounds and his diet: >Tonight’s calculations are based on Michael’s caloric requirements, and those requirements are as strict as they come. Unlike April’s daily average of about 1,300 calories, which really is an average (she likes to go out drinking and dining with friends on weekends, and doesn’t mind enduring a few 1,000-calorie weekdays to save up for the splurge), Michael’s regimen of 1,913 calories a day is exactly that: 1,913 calories every single day http://nymag.com/news/features/23169/index1.html http://nymag.com/news/features/23169/index1.html >There is emerging evidence that while CR is effective, an alternate approach that is less extreme could also be just as effective: intermittent fasting[1]. There are a lot of controversial things in CR research (high protein vs low protein for example) but one thing that has been pretty much conclusively established is that IF only gives CR benefits to the degree that it ends up lowering calories. Many people do find that IF makes it easier to stay on a restricted diet, but ultimately, it comes down to calories.

I know it has been found to be true in rats, non-human primates, etc, but humans already have abnormally long longevity for mammals (http://skeptics.stackexchange.com/questions/5701/does-every-species-get-around-a-billion-heartbeats-on-average http://skeptics.stackexchange.com/questions/5701/does-every-...). The types of changes calorie restriction triggers in other animals may have already be part of a regular human.
