@DetectiveHyde @wowaname Well yes and no. There are twhree factors that go into your carb limit that I can think of. 1) how many calories you burn in a day 2) how strong your insulin response is 3) your ratio of mitochondria to cells in your body.

WRT to #1 the more you exercise the more carbs you can eat. As long as your burning them off fast enough that you don't replenish your glycogen stores you should remain in ketosis.

#2 means if you have a stronger insulin response your body would probably store carbs more readily then burn them. I'm not 100% on this one but that could play a role.

#3 this is the most overlooked one though. People who are very active and physically fit, or people on keto for a long time, have an increased ratio of mitochondria. This in turn means they can break down sugar faster (and tend to feel more energized as a result).

Obviously fatter people are probably not doing too well on any of those three factors...
