When Diet Becomes a Trend

By Dr. Marian Assaad

In the age of social media, dieting is no longer just a nutrition plan recommended by a doctor or designed by a dietitian after understanding a person’s health, lifestyle, and needs. In many cases, it has become a short video, a dramatic personal story, a “before and after” photo, and one powerful promise: lose weight fast.

The problem is not that people want to feel healthier, lighter, or more confident in their bodies. That is a natural and understandable wish. The problem begins when the body becomes a testing ground for every trend, and when people start believing that any diet that goes viral must be safe, effective, or suitable for everyone.

Many of these diets can lead to fast weight loss, but fast weight loss does not always mean true fat loss or better health. Sometimes it simply reflects water loss, severe calorie restriction, or a temporary form of deprivation the body cannot tolerate for long. The U.S. Centers for Disease Control and Prevention says gradual, steady weight loss of about 1 to 2 pounds per week is more likely to be maintained than rapid weight loss.

One famous example is the Cabbage Soup Diet, which is based on eating cabbage soup for several days with very limited additional foods. Some people may see a lower number on the scale, but the more important question is: what did the body actually lose? Did it receive enough protein, healthy fats, vitamins, minerals, and energy to function properly? Rapid weight loss may look attractive, but it rarely teaches the person how to eat in a way they can continue safely.

Another controversial example is the Carnivore Diet, which relies almost entirely on animal products while excluding vegetables, fruits, grains, legumes, seeds, and nuts. The diet has become popular through influencers who describe personal success stories, but Harvard Health notes that this way of eating removes major plant-based food groups, including foods rich in fiber. That raises concerns about long-term health effects, even if some people lose weight at first.

Then there is the Baby Food Diet, which may sound simple because the portions are small and packaged. But adults are not babies. A grown body needs enough protein, fiber, healthy fats, calories, and nutrients to support work, movement, immunity, hormones, and daily energy. Replacing adult meals with jars of baby food is not a health plan. It is another form of restriction.

Juice diets are especially tempting because they look colorful, clean, and full of fruits and vegetables. But drinking juice is not the same as eating whole food. Juice may contain some vitamins, but it often loses much of the fiber found in whole fruits and vegetables, and it can deliver natural sugars quickly. The U.S. National Center for Complementary and Integrative Health says juice and detox diets may cause short-term weight loss because of low calorie intake, but weight is often regained once normal eating resumes, and there is no strong evidence supporting detox diets for weight management or toxin removal.

More dangerous is the water-only diet, where a person avoids food for several days and drinks only water. This can cause dizziness, fatigue, low blood pressure, and electrolyte imbalance, especially for people with diabetes, kidney disease, heart problems, pregnancy, older age, or those taking regular medication. Electrolyte imbalance is not a small issue, because minerals such as sodium and potassium are essential for the heart, muscles, nerves, and fluid balance.

Even well-known diets such as keto, Atkins, paleo, and intermittent fasting should not be treated as one-size-fits-all solutions. Some may help certain people when followed carefully and under guidance, while others may feel unwell or develop problems. Intermittent fasting, for example, may help some people organize eating times, but it is not suitable for everyone. Mayo Clinic Health System notes that intermittent fasting can cause side effects such as hunger, fatigue, insomnia, irritability, decreased concentration, nausea, constipation, and headaches.

Recently, other plans with attractive names have also gained attention, presenting food as a form of medicine or promising to improve digestion and reduce inflammation. The general idea of eating better and reducing highly processed foods may be helpful when placed within a balanced and safe plan. But the danger appears when the advice becomes a treatment promise, or when patients are encouraged to reduce water, stop medication, or remove many foods without medical supervision.

So why are people attracted to strange diets?

Because tired people want quick hope. Someone who gained weight after pregnancy, medication, stress, long working hours, poor sleep, or reduced movement may feel desperate for a fast solution. Social media knows how to sell that hope: a powerful story, a familiar influencer, a beautiful photo, and a caption saying, “Try this. It changed my life.”

What we often do not see is the exhaustion, headaches, dizziness, hunger, weight regain, or emotional damage that happens when a person feels they failed simply because they could not continue a harsh and unrealistic plan.

A successful diet is not the one that punishes you. It is the one that can live with you. It should fit your day, your work, your budget, your medical conditions, your medication, your activity level, and your food culture. A person with a desk job may need better calorie balance, more fiber, and more movement. An athlete needs enough energy, protein, and meal timing. A person with diabetes needs careful carbohydrate and medication management. Someone with digestive problems should not copy a plan from another person’s experience.

The golden rule is simple: do not remove an entire food group from your life without a clear medical reason. Do not trust a diet that promises dramatic results in a few days. Do not stop medication because of a video. Do not reduce water because someone claims it will “dry out” the body. And do not let the scale be the only judge of your health.

The safer model is not a strange trend. It is a balanced plate. Canada’s Food Guide recommends making half the plate vegetables and fruits, one quarter whole grain foods, and one quarter protein foods, with water as the drink of choice. This may sound ordinary, but it is far more realistic and sustainable than extreme restriction.

The World Health Organization also emphasizes that a healthy diet is based on a variety of minimally processed or unprocessed foods that are low in unhealthy fats, free sugars, and sodium. In other words, health does not need a strange name as much as it needs balance, consistency, and respect for the body.

The conclusion is simple: strange diets may be interesting to watch, but they are not always safe to try. Not everything that goes viral is true. Not everyone who loses weight becomes healthier. And not every diet that works for a friend will work for you.

The human body does not need a war. It needs a plan. It does not need harsh deprivation. It needs awareness. And it does not need a new trend every week. It needs a calmer and kinder relationship with food.

A real healthy diet is not a temporary punishment that helps us hate our bodies less. It is a way of living that helps us feel better, have more energy, protect our health, and keep our dignity beyond any number on the scale.
