you are NOT going to be depleted from lifting weights at the gym lol.. i always find it hilarious how people think that. go run a half marathon and then when you quit 1/4 of the way through you will know what really being depleted is!
if you are trying to lose weight let the wave run longer. don't eat for a bit.
that is 'extreme' but it will help you lose more weight..
the worst thing you can do is workout, burn 300 calories.. then go to chipotle and get a burrito that is 1000 calories with a soda and chips. you just ruined your entire workout
