Weight loss is not easy to achieve but Dr Michael Mosley has shared handy tips for anyone looking to get started.
The expert told Britons to eat plenty of protein if they are trying to slim down for good.
In fact, he recommended slimmers eat "at least 50 grams of protein a day" to get results "safely and effectively".
Foods high in protein include meat, fish, eggs, dairy, nuts and tofu.

Eating a high-protein diet has been shown to have huge weight loss benefits.
"Protein is the single most important nutrient for weight loss and a better looking body," experts at Healthline explained.
Protein is incredibly satiating which means it will keep Britons fuller for longer and less likely to reach for unhealthy snacks.
A study published in the National Library of Medicine showed a high-protein diet boosts the metabolism.
It found those eating on such a plan burned around 80 to 100 more calories per day while seeing a drop in their appetite.
Eating foods high in protein is particularly important for dieters when they exercise as it helps them to build muscle.
Dr Mosley added the importance of regular exercise as well as healthy eating when trying to lose weight.
"You should also take up regular exercise — particularly resistance exercise, such as press-ups and squats, to help preserve muscles," he told Daily Mail.

If short on time, Dr Mosley shared a hack for fitting in a workout.
He suggested people do what he calls exercise snacking - so, "exercise less, but more often".
The expert continued: "Break your exercise up into bite-sized chunks, perhaps three lots of 10 minutes."
He said short but frequent workouts could have positive effects on the overall health of slimmer.
Dr Mosley is the creator of The Fast 800 plan - a form of intermittent fasting - and he offers advice for achieving quick weight loss.
