I have done keto for several years. I ran into a problem when about 2 years ago hubby brought home a kid who was a psychopath with real bad ADHD. He lived with us for almost a year. It was like living in hell. Even tho my food choices didn't change, I probably ate more. Not too much more tho' because I track my diet on chronometer. I gained back about 20-25 of the 70lbs I'd lost. I developed adrenal fatigue and had to stop doing I.F. I'm getting better but still have days of total exhaustion and weepyness. I am back to doing I.F. I take some natural heart health stuff in the morning, then water with ACV, then tea with 2 tbsp MCT and stevia. I eat lunch around 12.and use various supplements recommended for me. I also battle chronic lymes.I know that My Creator made us to heal. I know that 1 of God's names, which show who and what He is, is Jevohah Rophe, that is the Lord God who heals. I know that God is a God of love and life, not nasty like most religion makes Him out to be. So I can totally believe that this too shall pass!
