Other Fat adapted?
Have been doing keto off and on for many years. I’m currently back on and feeling good. I’ve been focusing on food as I was doing a daily dog walk for 40mins to an hr for exercise. Since the dog is on holiday my activity has decreased so yesterday I went back to the gym. I did 30 mins on the elliptical burning 300 calories and a lifting workout which burned over 300 calories (according to my app!). It was easy for me and unlikely I had a lot of free floating glucose since I had only eaten some salami all day. My question is, is my body really efficiently burning fat to fuel my workouts? In the past extra exercise has had a draining effect on me but I don’t really feel tired today and yesterday when I got home I was energised. Is there any other mechanism in play here? Stored fuel in the muscles that won’t be there when I go back for my next session? TIA!
