Throughout history, the pursuit of weight loss has led people down some bizarre and sometimes dangerous paths. Fad diets, characterized by their short-term focus, restrictive nature, and often outlandish claims, have a long and disappointing history. This article explores some of the weirdest fad diets, from historical oddities to modern-day social media trends, examining their rationales, realities, and potential health consequences.
A Look Back at Historical Fad Diets
The desire for quick weight loss is not a new phenomenon. People have been trying unusual and sometimes dangerous ways to lose weight for centuries. Here are some examples from the 1800s and 1900s:
The First Low-Carb Diet
In the 1860s, William Banting, a London funeral director, followed a diet suggested by his doctor that involved reducing starches and sugars and eating three meals a day of fish or meat with vegetables and some fruit. He avoided bread, beer, sweets, milk, and potatoes. Banting lost a considerable amount of weight and shared his diet in a pamphlet called "Letter on Corpulence," which became hugely popular. While fairly low-carb, the diet allowed for up to seven glasses of wine or sherry daily.
The Great Masticator
In 1898, American businessman Horace Fletcher lost almost 40 pounds by chewing each mouthful of food up to 100 times. "Fletcherism" required chewing food until it became fluid. Fletcher wrote a best-selling book on the topic and traveled the world, spreading the gospel of chewing. He taught people not to eat until they were "good and hungry" and never to eat when angry or worried. Followers could eat anything they wanted as long as they chewed it until the "food swallowed itself."
Arsenic Pills
From the mid-18th century to the early 19th century, over-the-counter medicines containing arsenic were available. Arsenic is poisonous, but at low doses, it acts as a stimulant. However, the line between a slight energy boost and death was thin, and overdosing was a real risk. Some products didn't even mention arsenic on their labels, adding to the danger.

Tapeworm Diet
In the early 20th century, tapeworm capsules were marketed as a weight loss solution. The idea was that swallowing a capsule containing tapeworm eggs would result in the tapeworms hatching and eating some of the food consumed, keeping the person trim. However, tapeworms can cause abdominal pain, discomfort, cramps, diarrhea, nausea, dizziness, vomiting, vertigo, headache, tiredness, malabsorption, anorexia, muscle pain, constipation, vitamin deficiency, anemia, intestinal obstruction, and pancreatitis. Some species can grow up to 82 feet long.
The Alkaline Diet
Dr. William Howard Hay designed the Hay diet, now known as the alkaline diet. The idea is to avoid eating too many foods that become acidic after digestion, as Hay believed this would cause the blood to become more acidic, leading to disease. While it's true that blood pH must be balanced, the foods you eat don't affect blood acidity. Most fruits and vegetables are considered alkaline, while ultra-processed foods are acidic. Whole grains and dairy are considered acidic, and cutting these from your diet means missing out on nutrients.
"Reach for a Lucky Instead of a Sweet"
In the 1920s, Lucky Strike cigarette company launched a campaign encouraging women to smoke cigarettes instead of eating sweets. Nicotine suppresses appetite, so this campaign was aimed at getting more women hooked on tobacco. The candy industry retaliated, distributing information about the dangers of smoking.
The Grapefruit Diet
In the late 1920s and early 1930s, the 18-day diet rose to popularity. It involves eating an entire grapefruit with each meal, along with eggs, meat, and other high-protein, high-fat foods. Also known as the Hollywood diet, it was very restrictive, requiring people to eat only 600-700 calories a day and lacking nutrients.
Modern Fad Diets: A Critical Look
While some historical diets may seem absurd by today's standards, many modern fad diets are equally questionable. Here are some examples of modern fad diets:
Juice Cleanses
These programs involve drinking six or so ready-to-drink fruit and vegetable juices throughout the day, prohibiting solid foods. While this may help reduce calorie intake, the weight loss tends to be water weight from muscles, not fat.
Activated Charcoal
This diet is based on the idea that activated charcoal clings to toxins in the body and removes impurities like pesticides and unhealthy stuff found in non-organic or processed foods. However, there is no evidence to support these claims.
Macrobiotic Diet
This diet promotes optimal health by eating a vegan, whole-grain-based diet plus some beans and vegetables. Some versions allow fruits, fish, seeds, and nuts (but only once or twice a week), and strong spices are discouraged. It's not sustainable and can cause nutritional deficiencies.
Baby Food Diet
This diet involves eating upward of 16 jars of baby food per day instead of regular meals and snacks. While baby food is minimally processed, it doesn't provide enough nutrients for adults.
Colored Food Diet
Based on the idea that red/yellow-colored foods are the most palatable, this diet is designed to make food look less appetizing.
Bland Food Diet
This diet involves eating only bland foods to reduce the stimulation of hunger and prevent weight gain.
Nose-Plugging Diet
This diet involves plugging your nose while eating to reduce the enjoyment of food and decrease appetite.
Intermittent Fasting
This diet involves alternating between periods of eating and fasting. While there is some evidence that intermittent fasting may have health benefits, it is not a magic bullet for weight loss.
Ice Cream Diet
This diet involves eating five pints of special ice cream a day to control calorie intake and produce weight loss. While it may help with short-term weight loss, it can also cause nutritional deficiencies.
Ice Diet
This diet involves eating a liter of ice every day to lose weight. While drinking more fluids is generally a good idea, there is no scientific basis for this diet.
Gluten-Free Diet
This diet involves avoiding gluten, a protein found in wheat, barley, and rye. While it may lead to weight loss, it is not a sustainable long-term solution.
Raw Food Diet
This diet involves eating only plant foods that haven't been heated to more than 116 F. Food safety can be an issue, and people who eat exclusively raw end up with low levels of important nutrients like vitamin B-12.
Cookie Diet
This diet involves eating six to nine special 80- to 90-calorie cookies per day. While it may lead to short-term weight loss, it is not a sustainable or healthy way to lose weight.
The Prayer Diet
This diet involves praying to subconsciously enable you to eat less food or make healthier choices.
The Daniel Fast
This 40-day, multi-phase diet permits organic fruits, veggies, grains, fish with fins and scales, and meat and poultry. It prohibits pork products, processed foods, pastas and breads, and grains.
The Food Combining Diet
This diet involves starting your day with one kind of fruit and eating as much of it as you want. Then, you can wait one hour and switch to eating another kind of fruit in unlimited quantities, or wait two hours and progress to other food groups. You can combine protein and fat or carbs and fat, but no carbs and protein together. You can't mix fruit with any other foods, and you can't eat any artificial foods.
Cabbage Soup Diet
This diet involves eating soup two to three times a day, along with a few other foods depending on the day of the plan. It provides as little as 1,000 calories a day, which can slow down metabolism.
Factors Contributing to the Appeal of Fad Diets
Despite their questionable effectiveness and potential dangers, fad diets continue to attract people seeking quick weight loss solutions. Several factors contribute to their appeal:
Promise of Rapid Weight Loss
Fad diets often promise dramatic weight loss in a short period. This can be very appealing to people who are impatient or feel pressured to lose weight quickly.
Simplicity
Many fad diets offer simple rules and guidelines, making them seem easy to follow. This can be attractive to people who are overwhelmed by the complexity of nutrition science.
Testimonials and Anecdotes
Fad diets are often promoted through testimonials and anecdotes from people who claim to have had success with them. These stories can be persuasive, even if they are not supported by scientific evidence.
Social Media Influence
Social media has played a significant role in the spread of fad diets. Influencers and celebrities often promote these diets, making them seem trendy and desirable.
The Dangers of Fad Diets
Fad diets can be dangerous for several reasons:
Nutritional Deficiencies
Restrictive diets that eliminate entire food groups can lead to nutritional deficiencies. This can have serious health consequences, especially over the long term.
Metabolic Slowdown
Very low-calorie diets can slow down metabolism, making it harder to lose weight and maintain weight loss.
Muscle Loss
Rapid weight loss often results in muscle loss, which can further slow down metabolism and lead to a decrease in strength and energy levels.
Disordered Eating
Fad diets can promote disordered eating patterns, such as binging and restricting. This can lead to eating disorders, which are serious mental health conditions.
Health Risks
Some fad diets involve potentially dangerous practices, such as taking diet pills or consuming harmful substances. These practices can have serious health consequences, including death.
Sustainable Approaches to Weight Management
Instead of relying on fad diets, it's important to adopt sustainable approaches to weight management that focus on long-term health and well-being. Here are some tips for sustainable weight management:
Focus on Whole, Unprocessed Foods
Eat a diet rich in fruits, vegetables, whole grains, lean protein, and healthy fats. Limit your intake of processed foods, sugary drinks, and unhealthy fats.
Practice Portion Control
Pay attention to portion sizes and avoid overeating. Use smaller plates and bowls, and measure your food if necessary.
Exercise Regularly
Engage in regular physical activity, such as walking, running, swimming, or cycling. Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
Get Enough Sleep
Lack of sleep can disrupt hormones that regulate appetite and metabolism, leading to weight gain. Aim for 7-8 hours of sleep per night.
Manage Stress
Stress can lead to overeating and weight gain. Find healthy ways to manage stress, such as yoga, meditation, or spending time in nature.
Seek Professional Guidance
If you're struggling to manage your weight, consider seeking guidance from a registered dietitian or other qualified healthcare professional. They can help you develop a personalized plan that meets your individual needs and goals.
