I notice that days where I don't eat much, I sometimes fail to get up big lifts with weights.
On days when I sometimes get big surpluses, such as big feasts/etc., I feel powered and like there's lots of more driving force/energy in completing lifts. It's like a big surplus gives you more power.
Is there any explanation for this? Is this why a lot of heavy/obese people can get some big weights moving (like perhaps bench, deadlifts, presses, etc.), despite them not having too much training/etc.?
It's like there's a correlation between intake and outward energy from the foods/etc.
