Viewers have seen chef James Martin's weight loss transformation over the years. Not only has he shed five stone, the presenter has managed to keep the weight off.
After competing in Strictly Come Dancing back in 2005, James credited his dramatic weight loss to a heart-healthy protein. It turns out a straightforward meal of salmon and veg helped the TV chef stay trim.
He previously shared: "To say that good food is elitist is just tosh. Good food is simply cooked food - it's not rocket science. What could be simpler than pan-frying a little bit of salmon and serving it with some great new potatoes and seasonal veg?"
Despite being an award-winning culinary master, James' cooking habits were poor, the chef said. He revealed that he used to be partial to a takeaway, Mars Bars and fizzy drinks, the Express reports.
However, he ditched these for home-cooked food, filling up on fruits and veggies.
Oily fish is great for heart health, as it contains long-chain omega-3 fatty acids. With a history of heart disease in his family, the chef prioritised eating this particular food at least twice per week.
He also fronted a national campaign encouraging people to eat at least one portion of oily fish every week, joined by Sports presenter Gabby Logan and Chefs Rick Stein, Brian Turner and Nick Nairn.
For an island nation, Brits aren't known for eating that much fish - much to our detriment.
James revealed: "One of the sad things is that heart disease is actually preventable, and yet nearly 2.5 million people have it and 120,000 of us die of it every year."
The NHS listed examples of oily fish: Herring (bloater, kipper and hilsa are types of herring), pilchards, salmon, sardines, sprats, trout and mackerel. Fresh and canned tuna do not count as oily fish.
"Oily fish contains long-chain omega-3 fatty acids," states the NHS. "Long-chain omega-3 can help to prevent heart disease. Oily fish is the richest source of long-chain omega-3."
Some white fish, such as sea bass, sea bream, turbot and halibut, are also a source of omega-3 fatty acids. The main shellfish sources of long-chain omega-3 are mussels, oysters, squid and crab.
James criticised the nation's general approach to food, explaining that while we might "admire the Mediterranean diet", we do not follow it.
He previously told The Herald: "On holiday, we insist on going to restaurants that serve the full British breakfast, and at home, we just slather on the butter and eat far too many processed foods."
The Mediterranean diet consists of the following: plenty of fruits and vegetables, whole grain bread and cereal, nuts, pulses (peas, beans and lentils), seeds, and high-quality proteins such as chicken and turkey over red meat sources. Foods high in saturated fat should be limited.
In addition to his newfound healthy diet, James explained that exercise also helps "keep the weight off". He told Saturday Kitchen: "I lost so much weight, about four and a half to five stone, it's unbelievable."
