Calorie restriction is still a rather uncharted territory for science. Researchers have found conflicting data on whether calorie restriction might increase longevity for humans, based on studies in insects, mice, and primates. However, it does seem fairly certain that
15-25% calorie restriction from the norm/free eating is definitely helpful for health at least. This would make sense, because our ancestors would not have had such easy and prolific calorie intake as we do now.
I think also there may be more to it than just calories. I think that maybe a combination of calorie restriction and
moderate exercise is the real answer to longevity and health. As well as maintaining a
low bodyfat percentage, well under what is considered "normal" today. For example, for females of my age, 23% bodyfat is considered "normal", but to me, 14-15% feels much better and more natural.
Some people may practice calorie restriction by doing
intermittent fasting: skipping meals once a day or two days a week. I've experimented a bit with it, but it caused me digestive upset. What currently works better for me is just three very small meals per day. I weigh my foods to keep my caloric intake under control. Maybe sometime later I can experiment more with fasting, because it does seem very natural for humans to have to fast from time to time. But I will most certainly continue with calorie restriction. It's easier than you'd think, because when following a ketogenic diet, ketosis naturally curbs hunger. Studies are showing that a
restricted calorie ketogenic diet is extremely helpful for treating a variety of diseases! And it certainly has worked for me!
