Hello!! I'm reaching out for advice. I'm not an athlete on any kind of way, but I do keep a pretty busy schedule. My friend and I like to do some running and we will do a half marathon here and there. So, it's been two years since our last half and we decided to start training. I was doing fine but I have gained about 30 lbs since the last half marathon and I was feeling it on my knees. So, I needed desperately to loose some weight and help out my joints. I started Keto two weeks ago. First week, i did my usual run and things were fine. Week two on Keto, I can barely move my legs. My legs feel so heavy and I'm exhausted. I went from 12 min mile to 14 and 17. I just need to know that there is hope at the end of the road. I don't expect overnight to go back to my glory days of 10 min miles-that was 30lbs ago. But I hope I can at least go back to 13 and have more energy. My runner's high/ burst of energy after my run is gone . Any advice or experiences would be greatly appreciate it.
