Adam Woodyatt has played the role of Ian Beale in EastEnders since 1985. He previously explained a low carb diet plan and exercise helped him lose weight.
In 2019, Adam took to the streets of London once more to complete the 26-mile race.
Running can be a great way to get into shape as the cardio exercise requires little equipment.
Experts at Healthline.com commented: “Running is an excellent choice of exercise for weight loss because it burns more calories than many alternatives.”
A study published in the US National Library of Medicine showed the activity burns more calories than most other exercises as it uses a range of different muscles.
How many calories it burns can change depending on the runners height, weight and speed.
However, the average runner will burn an impressive 80 to 140 calories per mile.
Some slimmers can burn more than 1,000 calories in just one hour of running.
While training for two marathons, it is no surprise Adam managed to shift a few pounds.
When following a low carb diet plan, those hoping to lose weight can tuck into foods including meat, fish, fruit, vegetables, nuts, tofu and eggs.
They will avoid foods that are high in unhealthy carbs such as sugar.
This can include meals such as bread, pasta, rice and sweet treats.
