I’m not doing Keto rather low carb. Best thing I’ve done. I have lost 54lb since Mid March.
I’ve limited my alcohol intake significantly and make all my meals using fresh ingredients every day.
It’s been 10 years since I last weighed under 20 stone and currently 18 and a half. I now can walk well over 4-5 miles per day where before I couldn’t walk half a mile without chronic back ache. So for me this is a lifestyle change.
Great going mate, that’s a huge loss and has to be good for you no matter how you do it. I was pretty much the same as you at nearly 22st and struggling to walk far etc, I’ve lost over 5st with SlimmingWorld and feel fantastic, just going out now to do a 5K walk with the dog whereas before I’d struggle to do 1 K, good luck mate.
