Nutrition know-all Michael Mosley has helped many shed weight with his famous plans such as the 5:2 diet.
The expert has appeared on various TV shows explaining his methods, introducing the 5:2 diet in a 2012 documentary Eat, Fast and Live Longer. The diet requires slimmers to limit calories to around 500 to 600 for two days of the week, with the remaining five of seven days routine food days.
The diet expert has also released another intermittent fasting-based diet called the Fast 800 that permits slimmers to eat around 800 calories per day. To find out whether the diet really works one WalesOnline reporter decided to give it a bash for a week, documenting the results.
