AceShowbiz - Lewis Capaldi's vegetarian health kick inadvertently caused him to pile on the pounds as he turned to carbohydrates in place of meat.
The "Someone You Loved" hitmaker, 23, is a renowned fan of British bakery chain Greggs, and notably set up a $6,300 tab for fans to eat there after a gig in Glasgow, Scotland.
However, he blames his rotund frame on his attempts to go vegetarian rather than his enthusiasm for pastries - as cutting out meat led to him feasting on carb-heavy junk food.
"I lost two stone at the end of 2018 and I thought, 'Now I've slimmed down a bit I'll be a vegetarian,' " he tells Britain's Daily Star newspaper. "I'll keep the weight off and I'll be doing good for the environment."
"But oh my God, I got so fat and put all that weight on again because I was substituting meat and veg for the vegetarian option which was pizza and chips."
The Scottish singer hasn't, however, ruled out going veggie again if he can lose a few pounds - something he's trying to do by reluctantly taking up jogging.
"I go on runs," he adds. "I go running every morning and it's been horrible."
