Why Fad Diets are Harmful to Overall Health


Fad diets are characterized as popular eating-habit trends that promise immediate results. Beyond a quick fix, a fad diet typically promotes some type of “magic” combination of certain foods that excludes certain essential nutrients and encourages following other unnecessary rules to focus on changing your body chemistry and losing weight fast.

While indeed, such fad diets have helped thousands of people lose excess weight and stubborn pounds, they’re also dangerous. These regimens cut out key nutritional foods that you need for overall health and wellness.

Examples of Fad Diets
While many of these diets are advertised to help you shed pounds seamlessly, most of them are harmful and ineffective. Here are a few examples of fad diets:

1. Low-fat diet – Encourages you to buy products that are labeled “low-fat” but in reality these processed foods are made with more sugar, sodium and other harmful additives.

2. High-protein diet – This regimen proposes that if you eat large portions of meat and eggs for protein, you’ll build maximum muscle and lose excess weight. However, meat and dairy products are loaded with added fats and exceeding your daily protein recommendations can lead to liver and kidney issues.

A high protein diet relies on consuming large quantities of meat and dairy products.A high protein diet relies on consuming dangerous quantities of meat and dairy products.

3. All-cabbage diet –  It’s said that eating nothing but cabbage soup for a week can help you lose up to 10 pounds of excess weight. But these pounds shed are most often just water weight, which means you’ll end up gaining it back as soon as you stop following this regimen. Additionally, this fad diet is high in sodium and low in protein, which could increase feelings of fatigue and weakness.

4. Grapefruit diet – Does restricting yourself to eating only grapefruit sound fun and healthy? Not quite. This diet promises weight loss if you eat nothing but grapefruit, but that means you won’t get the calories, vitamin and minerals you need to thrive.

Why Are Fad Diets So Harmful?
While some of these diets may seem less harmful than others, it all comes back to one main hardship: these dietary restrictions won’t have all of the essential nutrients your body needs to thrive.

“Most fad diets center on eliminating certain food groups or limiting to only specific ‘healthy’ food choices,” Anna King, a registered dietitian at Riley Hospital for Children at Indiana University Health, told Indiana University Health. “Each food group provides its own unique set of vitamins, minerals and energy for the body.”

Because fad diets tend to completely cut out certain food groups, your body may react negatively to the inadequate vitamin and mineral intake. Some of the following symptoms could occur while following a fad diet, according to the Victoria State Government Better Health Channel:

  • Dehydration.
  • Fatigue and sudden weakness.
  • Nausea.
  • Severe headaches.
  • Constipation.

    I agree that some of the fad diets can be dangerous. They also do not teach a person to eat in a healthy way. So when a person stops the fad diet, he or she goes right back to eating poorly and often gains the weight back again.

    I encourage people to follow the Hallelujah Diet to regain their health. When they focus on getting their body healthy, weight loss will be an extra benefit.

  2. I know a lot of my family who falls for the fad diets. I have seen them become very weak and sick from trying to stick with one of those unhealthy diets. The main thing I have also seen is the weight does not stay off when it’s lost through a fad diet. Its great we know how to change our lifestyle to eating healthy and giving our body the fuel it needs to stay fit and healthy.

  3. I love this article, we are always looking for a “quick fix” and a fad diet can look very enticing. However you never seem to be able to keep the weight off. Changing your lifestyle and they way you eat permentaly is the best way to make those changes.

    What about the Keto’s diet ?

    • Melody Hord October 8, 2019

      According to Olin Idol, VP of Health for Hallelujah Diet, “The Keto Diet is not supported by biblical principles of Genesis 1:29 nor is it supported nutritionally by good science. It has produced short-term results in weight loss and some neurological conditions but is not sustainable long-term and in general will not support long term health.”

  5. Great read, thank you for sharing information on the different diets that our there and how they can end up doing more harm than good to our bodies.
