5 Reasons why Crash Diets are Harmful to Your Health

Weight loss is one of the most common fitness goals among people. Though there are plenty of ways to lose weight, many of them are not always safe for you.

Crash diets are diets set up to help people drop weight quickly, these extreme dieting methods can cause many issues and even ruin your efforts once you stop the specific crash diet.

Everyone wants to lose weight as fast as possible because, let’s be honest, the quicker the better, but check out these 5 reasons why crash diets are harmful to your health and you might change your mind about the speed of weight loss.

  • Nutrient Deficiencies

Most crash diets involve eliminating certain foods from the diet for a given amount of time. After a while, your body can become deficient in essential nutrients causing an array of health issues and side effects.

For some crash diets, you might only be drinking a special juice blend daily or a specific strict menu such as eggs, grapefruit, and water, or perhaps the diet consists of only eating 3-4 apples per day for 1 week. These types of diets are dangerous and do not provide the body with essential fats, proteins, or carbohydrates that are needed for proper brain function and other functions that go on in the body.

Our bodies need a wide variety of nutrients in order to perform and function properly, so it’s important not to omit these from your diet for any length of time, but to ensure that you are eating various healthy whole foods so that your body will have exactly what it needs for good health.

Not many realise that losing weight can be rather simple. A good diet, lots of exercise and invest in an effective fat burner like Ultra Omega Burn.

  • Slower Metabolism

Metabolism is the rate at which your body burns/utilizes energy (Calories), after going on an extremely low-calorie diet, the metabolism is slowed down in order to conserve energy for functions such as digestion, respiration, brain function and much more.

All humans need a certain number of calories each day just to complete these functions, this does not include any type of activity such as exercise, the number of calories a person needs for these bodily functions is known as your BMR (Basil metabolic rate). Eating too few calories can not only slow down the metabolism, but it can also make a person feel weak, dizzy, fatigued, and lead to more health issues over time.

  • Muscle Loss

With crash dieting, it not only comes with losing body water and nutrients, but by eating a limited amount of protein, it can come with loss of muscle as well.

According to recent studies, crash dieting can deplete as much as 3 times more muscle than a long-term healthy diet plan. That’s pretty scary considering muscle is needed for a strong and healthy body.

Loss of muscle mass also leads to a slower metabolism as the more muscle a person has, the more calories will be burnt, even while at rest, so this can then lead to taking even more effort to lose weight and keeping it off.

Losing muscle mass too quickly can lead to irreverisible stretch marks. Not something you want showing when you’re in your beach wear.

  • Extreme Fatigue

When your body and brain is not getting the proper nutrition as it doesn’t with crash dieting, this can make you feel extremely weak and fatigued during the day. Fatigue can be dangerous for many people, especially if you have a job that requires you to operate heavy equipment, if you are a parent taking care of a little one, or if you need to drive somewhere, it’s just not safe to do so under these circumstances.

  • Heart Issues

Studies show that people who take part in yo-yo dieting are 3 times more likely to encounter a heart attack.  The reason being, is that if a person cuts too many calories from their diet for too long, not only is skeletal muscle lost, but the heart can also lose muscle, causing tears and weakness in the heart which can lead to a sudden heart attack.


As you can see, crash diets can cause a lot of health issues, they can even lead to weight gain as well, ruining all of your efforts and wasting time. The best way to lose weight and keep it off is through a healthy diet including a variety of nutrients, drinking plenty of water, getting sufficient rest and ensuring that you are keeping active. Slow and steady always wins the race when it comes to weight loss.
