Never really been all that chunky, I'm slim by nature, but I piled on the pounds from the first lockdown and it was really shit. However, I'm coming to the end of my usual start of year fast (completely cut out any treats - no chocolate, no crisps, no donuts, no sweets, no cake, etc) and the weight is tumbling off. Lost over 2 stone in around 3 months.
Haven't been exercising at all, just going for a few long walks to the supermarket a couple of times a week. It really is all about diet and knocking those calorie counts down, though I admittedly started from an easier situation as I'd put the weight on pretty quickly too.
