A fitness fanatic who admitted becoming unhealthily obsessed with counting calories has co-founded a new online grocery business to help others.
Sonny Drinkwater had reduced his daily intake to around 1,000 calories while exercising 20 times a week, until he realised something was wrong.
He said it took a "massive toll" on his mental health while at university.
After learning about nutrition, he co-founded WellEasy to help make healthy food affordable to anyone.
"I've had quite obsessive traits from a young age," said the 24-year-old.
"I looked at food, and started to cut calories. I had a six-pack, it was a competition, an achievement. It looks great on Instagram but you don't realise what you are doing.
"I started getting ill and colds, and couldn't go out with people eating at a restaurant as I'd get anxious about what I was eating."
Mr Drinkwater, a former student at the University of Bristol, said he realised something was wrong when his mum confronted him on a family holiday.
"I didn't share a protein powder with my dad as I'd rationed it all out for my meals.
"That was a big moment for me, I remember being upset at the time. But it's one thing realising something, the big part is doing something about it."
In January 2021, Mr Drinkwater co-founded WellEasy from his parents' garage. The aim is to sell healthy food online at wholesale prices for a membership fee.
"The biggest issue for us was that as students we couldn't afford the nutritionally-complete foods we wanted.
"Our big mission is to make it accessible to everyone, through education and pricing."
Every new customer sponsors a free membership for a low-income family, NHS worker, teacher, student or armed forces veteran.
"I now understand about the difference between the calories in a burger and the calories in an avocado," said Mr Drinkwater.
"Calories are a good thing to be aware of, a good measurement to keep in mind, but I think for a lot of people, especially young people today, it can go too far and be all-consuming.
"It's a completely different relationship with food for me now. I love food, I look at it now for what it gives me, not something that it takes away."
