Working around food can make it difficult to keep the kilos under control, a struggle British TV chef Jamie Oliver battled with.
But knowing he needed to make a change, the 44-year-old dad of five revealed that he cut one major thing from his diet, and the results spoke for themselves.
Talking to Radio Times, he said "I pushed meat down, pushed veggie up, got more sleep and more movement."
Looking for vegetarian alternatives to meat-based meals, he says he's adapted to choosing nuts to help get his fat and protein intake where possible.
"They make you half as likely to have a heart attack," he explained, and recommended that kids should look to them as healthy snacks.
His other trick was cutting back on the weekday wines.
"Your average Brit drinks booze. I'm not telling you what to do, but my rhythm now is only to drink at the weekend," he said.
His newest cookbook 'Veg' released last year looks at how meat-eaters or full-time vegetarians can celebrate good, tasty food which happens to be meat-free.
"It's about a consciousness and knowing you're doing something and being more mindful."
"I lost 12 kilos quite quickly and I didn't do it through not eating."
