If you’re trying to lose weight, you’ve probably been through the rigmarole of figuring out the pros and cons of all the diets that have been floating around of late, whether it’s, low carb, high protein, cleansing, or calorie-counting.
Of course, everyone responds to dieting in different ways, but once we strip away all the hype and marketing, which ones have the best scientific evidence behind them?
In their latest video, the boys from AsapSCIENCE run through the popular diets and figure out which ones will give you the best chance of losing weight - and not putting it back on.
Dieting and losing weight should be fairly simple - if you want to maintain your weight, don’t eat more calories than you burn, and if you want to lose weight, eat less calories than you burn.
So that would mean calorie-counting diets like Weight-Watchers should be pretty foolproof - eat whatever you want, as long as you stick within the daily calorie guidelines.
While that might sound like cheating - because you could just eat junk food as long as it's within the limits - the video above actually has a much smarter way to do this, so you can cut your calories by an additional 20 percent - and avoid the heightened risk of heart disease.
South Beach, Atkins, Zone - they’re all marketed as different products, but they all follow the same principle: carbs are the enemy.
The rationale is that if you consume more carbs than you can burn off, your liver converts them into fats. But for most healthy people, your carbs are far more likely to be converted into glucose to give your cells energy.
That said, not all carbs are created equal - as the video explains, some do have a higher chance of ending up as fat than others.
So rather than never eating pasta or fruit again (don’t even talk to us about alcohol restriction) you’re better off just being smart about the carbs you eat.
And stop trying to take vitamins to replace all those good carbs you’re not eating - they don’t work.
The rationale behind high-protein diets like the palaeo diet is that high-protein foods are more difficult for your body to break down, meaning you’ll stay full for longer than if you ate the same amount of food in carb-form.
As AsapSCIENCE explains, while some people have found success using these diets, they unnecessarily cut out key food groups, like grains and legumes, that are good for our bowels. They could also seriously mess with your longevity too, so you need to be really careful.
And did someone say terrible farts?
Don’t. Just, don’t.
And while we're on the subject of 'quick fix' diets, know this: there is no 'easy' or fast way to lose weight. The faster you lose it, the faster you tend to put it back on.
As researchers found when they tracked Biggest Loser contestants after the show, intense weight-loss can actually change your metabolism forever, so you'll not only put the weight back on, you'll actually find it even harder to lose it than you did the first time around.
Watch the AsapSCIENCE video above to find out the best way to lose weight - spoiler: 'dieting' as it's been marketed to us is not the way to go.
