Yeah, I have been pushing my body towards ketosis but I keep carb loading every other day so till I finally stop doing that I won't be lol. I just started lifting weights as I use to lift weights back in the day before I got fat! I usually walk/jog/hike 5-6 miles daily but I kinda got bored of it lol. But, low impact would be ideal because through out like 30 plus days I had forced myself to walk/jog on blisters lol. I don't think my body is burning muscle though as all the muscles I had under my fat is pretty much still there and a little bigger now strangely lol. Expect my arms they never were that big. Yes, fasting is hard! It's day 40 now and I kinda keep forgetting that I have gone that far! At this very point it's starting to feel like I have been doing it for months! Kinda crazy lol. That is only because I can't really remember a day without fasting over 18hrs.
