00:00 A new and more extreme diet is gaining popularity in order to manage weight and keep fit.
00:06 The one meal a day or OMAD diet is a form of extreme fasting in which a person eats
00:12 all their calories in one single large meal.
00:15 Science Alert reports only one study has been done on the effects of OMAD in humans, and
00:20 the conclusion was although participants saw a greater reduction in their body weight and
00:25 fat mass, they also had greater reductions in lean mass and bone density when eating
00:30 just one meal a day.
00:32 Meaning that if the diet was to be followed for a long period of time, there would be
00:36 a greater risk of bone fractures and reduced muscle function.
00:40 There's also a risk that the person only having a meal a day is not meeting all their nutritional
00:45 requirements like enough protein, fiber, key vitamins and minerals.
00:50 If you read about celebrities successfully losing weight on OMAD, remember they have
00:54 easier access to nutritionists, high quality diets and supplements where needed.
00:59 Science Alert concludes that for most of us, this kind of diet could be unsustainable and
01:04 potentially harmful in the long run.
