What is a Fad Diet?

Before we can learn how to spot fad diets, it’s important to know exactly what a fad diet is. If you are unfamiliar with the term, here are a couple of ways Google defines the term fad diet.

• A diet that involves eliminating foods that contain necessary nutrients and sometimes cutting out entire food groups
• A stylish weight loss plan that promises dramatic results
• A diet that is popular for a time, similar to fads in fashion
• Any of a number of weight-reduction diets that either eliminate one or more of the essential food groups or recommend consumption of one type of food in excess at the expense of other foods
• A diet that rarely follows sound nutritional principles
• A diet that makes weight loss seem easy and quick

Are Fad Diets Harmful?

The short answer? Yes. The long answer? Also, yes. This makes learning how to spot a fad diet very important.

Fad diets exist because society has taught us that we need to change our bodies. Society has ingrained in us that the less we weigh and the skinnier we are, the more beautiful and valued we are. Fad diets act as a quick solution to this problem.

Fad diets harm our relationship with food. This is done by demonizing certain nutrients such as carbohydrates or fat. This makes it seem as though these nutrients will cause us harm or make us bad people when we eat them. This thinking leads to avoidance, guilt, shame, and disordered eating patterns.

Fad diets promise quick weight loss, which will most likely lead to weight regain. Not only is this harmful to our self-esteem, but it’s harmful to our bodies. Weight cycling can cause a serious disruption in our body’s metabolic rate and promote poor cardiovascular health.

Fad diets can lead to deficiencies or abnormalities within the body. For example, the Keto Diet, a popular fad diet, focuses on a low carbohydrate, high protein intake. Diets like this are often high in butter, meat, eggs, cheese, and poultry. The majority of these foods are high in fat, specifically saturated fat, which can increase bad cholesterol and triglycerides while also increasing the risk of heart disease and type 2 diabetes. However, Keto is just one example of how fad diets can cause harm to our bodies.
