Diet fads come and go, but when it feels like there’s a new “secret” to weight loss every week, how do we know what will really help us shed pounds? This question is examined in AsapSCIENCE’s video, “Which Diets Actually Work?”

In a world where 97 percent of diets fail within three years, there is a necessity to debunk rumors about the body's nutritional requirements and how it breaks down fat.

For example, carb-restricting diets like South Beach, Atkins, and Zone suggest that sugar and gluten are enemies. But, in reality, different kinds of carbs are broken down differently, and following these restrictions can lead to constipation, dry mouth, bad breath, fatigue, dizziness, and nausea, according to the video.

“The truth is most diets focusing on quick, dramatic results also have a yo-yo effect where you lose initial weight, but slow down your metabolic rate so your body starts burning less calories, and then, when you start eating again, there’s all the weight back and more,” the host states in AsapSCIENCE’s video.
