The 15 Most Popular Crash Diets of 2019

The 15 Most Popular Crash Diets of 2019

by Alex Hirsch (SU)

Many special occasions serve as motivators for rapid weight loss: a wedding, a summer vacation, or a class reunion are just a few prime examples. People trying to lose weight quickly know that crash dieting – while not necessarily the healthiest – can be the most effective option when time is of the essence. 

Crash diets (also known as fad diets) involve reducing calorie intake drastically, such as consuming 800 to 1,200 calories per day, for a short period of time. Crash diets, however effective, are not sustainable for the long-term. But people will continue to turn to them for their short-term weight loss goals. You should remember that frequent crash dieting is actually unhealthy.

The best solution for keeping the excess pounds off would be to think long-term and follow a diet that is healthy and nutritious – one that will banish your cravings for high-fat, high-sugar, processed foods.

With that said, if you've got your heart set on a crash diet – and you don't have any contraindicating medical conditions – it's helpful to know which crash diets are making a smash in 2019. Here’s a roundup of the 15 most popular plans:

Lemonade Diet

Beyoncé famously went on this diet to prepare for a movie. Also known as the Master Cleanse, it entails only consuming a special spicy formulation of lemonade for two weeks. There is no doubt that you’ll lose weight – but you might also lose your mind in the process.

Paleo Diet

The idea behind the Paleo diet is that if you eat like a caveman, you will not suffer from diseases that plague modern humans. It involves shunning refined and processed foods, and eating only red meat, poultry, fish, and vegetables.

Dukan Diet

The Dukan diet is by a French celebrity named Pierre Dukan. It is a high-protein, all-you-can-eat diet that eliminates carbs. It targets your body’s fat storage, and it makes you lose 10 pounds in the first week and anywhere from 2 to 4 pounds in subsequent weeks.

Atkins Diet

The diet created by Dr. Robert Atkins remains popular even now, and will go down in history as one of the most popular diets of all time. It restricts carbs – no bread, pasta, or rice – which leads to fat burning.

Fast or 5:2 Diet 

This diet utilizes intermittent fasting or alternate-day fasting. You fast for two consecutive days per week (600 calories per day from protein-rich food for men, and 500 for women) and eat as you normally would for the five remaining days.


The DASH diet has you eating only foods rich in potassium, magnesium, and calcium. The idea is that these nutrients counteract the effects of sodium, ultimately leading to better heart health. Fatty, sugary, and processed foods are limited, as well as sauces, condiments, sweeteners, jams, and syrups.

Volumetrics Diet

This diet was developed at Penn State and features more vegetables and fruits by experimenting with different ways to eat both. The focus is on high-fiber foods and also water.

It's popular because it makes people feel like they can eat a lot without constantly thinking of limiting themselves. You change your approach to eating rather than prevent yourself from eating.

Ketogenic Diet

The "keto" diet is the most popular diet of 2018, and it remains popular for its effectiveness. It works by decreasing insulin levels through shifting your source to ketones, which are compounds made from fatty acids. In the absence of carbs, your brain and other organs will burn ketones for energy, and you enter a state of ketosis.

Zone Diet

The Zone diet was created by a biochemist and calls for a strict ratio of protein, fat, and carbs, which reduces inflammation and enables weight loss. Your calorie breakdown should be as follows: 30 percent lean protein, 30 percent healthy fat, and 40 percent high-fiber carbs. The foods should be consumed in blocks, whether as meals or snacks.

Vegan Diet

The vegan diet has been criticized for its severity and unbalanced nature. You eat foods that contain no animal products, which has an ethical aspect to it. Your diet consists of whole grains, fruits, vegetables, legumes, nuts, and seeds.

South Beach Diet

Dr. Arthur Agatston aims to help people lose weight in a sustainable manner without experiencing hunger pangs. The South Beach diet is very similar to the Atkins diet but with a lower-carb, lower-fat, high-protein variety. Its restrictive nature decreases as you pass the initial stages.

Grapefruit Diet

This diet has you consuming as much grapefruit as you can for 12 days in a row and then taking time off for another 12 days. On this diet, you risk gaining back all the weight you lost and also passing out from hunger!

17-Day Diet

Four cycles make up the 17-Day diet: Accelerate, Activate, Achieve, and Arrive. Each one of the first three cycles introduces you to new food options, and they last 17 days each. After Achieve, you reach Arrive, where you will have the diet that you should have for life. The good news is that calorie-rich options are introduced as you move along.

7-Day Raw Food Diet

On the raw food diet, you'll eat meals that consist of uncooked foods and juices. The emphasis is on raw, fresh vegetables, sprouts, nuts, seeds, and fruits, along with fresh vegetable and fruit juices. It's meant to reset your system and help you transition to a vegan diet.

Juice Fasting Diet

This diet promises healthy and glowing skin as an added bonus. Juice fasting requires only juice (70 percent should be vegetable-based), decaffeinated herbal teas, fresh fruit, and strained vegetable broth for five days. Avoid caffeinated teas, milk, coffee, and soda. Your body will have the chance to cleanse itself of toxins.
