Good for you Jim, well done!
Like you my weight had crept up over the years without really realising from 11.5 stone 16 years ago when I left the RAF to 15.5 stone. Found myself visiting the GP for various things more recently.
Started a low carb diet at the beginning of the first lock down, lost 3 stone. Plenty to eat of the right things never felt hungry. All the things that the GP was treating me for have cleared up now. Acid reflux gone, piles gone, loose stools normal now, knees dont hurt....
Keep going mate, keep sharing your success with us.
