It’s impossible to count the number of weight loss and fad diets that have emerged over the years as the next quick fix for shedding pounds.

However, few, if any, of these fad diets actually work on a long-term basis. When approximately 35.7% of American adults are obese, it’s easy to see that few of these headline-grabbing weight loss solutions actually remove unwanted fat and lead to healthy lifestyles.

That’s because these diets often advocate for removing one or more crucial food groups from your diet, leading to a number of harmful physical and mental effects. And if you don’t qualify for a liposuction procedure, you might just be making things worse for yourself.

Want to make sure you don’t accidentally try out one of these fad diets? Here’s a look at the three worst weight-loss plans that you should strive to avoid:

The low-fat diet

Eliminating fat from your diet might seem logical — since you’re trying to lose fat, you should stop eating foods with fat, right? In reality, your body needs healthy fats in order to survive. Foods that are marketed as “low-fat” tend to have higher levels of sugar, which is no better for you. Instead, focus on eating healthier fats like olive oil, avocado and flax seeds. While these fats are calorie-dense, they’ll help you stay fuller longer.

Extremely low-calorie diets

Lowering your daily calorie intake can be a great way to lose weight — as long as you don’t restrict your intake to dangerous levels like some fad diets advocate. Slashing your calorie intake too much can cause you to have an unhealthy relationship with food, and can even lead to dangerous nutrient deficiencies.

The juice cleanse

Another super-trendy fad diet? The juice cleanse, which involves consuming nothing but juice for a few days in order to shed fat. However, many juice cleanse drinks are nothing more than sugar water, meaning you miss out on the proteins, carbohydrates and fats that your body needs to survive. Even if you do lose weight during a juice cleanse, it’s likely you’ll end up gaining it back once you go off the cleanse.
