Doctors generally disapprove of diets that promise rapid weight loss and lack nutritional balance. They warn that strict, exotic, or mono-diets and unnecessary food restrictions can be harmful.
Break the Monotony
Relying on a monotonous diet, typical of mono-diets (like apple, egg, or beet diets), can lead to a deficiency of essential micronutrients in the body. Missing vital nutrients can cause problems with nutrient absorption, appearance, and organ function. Mono-diets are particularly dangerous for people with chronic illnesses or a predisposition to them—conditions that affect more than two-thirds of adults. For instance, an apple diet can exacerbate gastritis and lead to ulcers, a citrus diet may trigger allergies, a carrot diet can cause carotenemia, and a high-protein diet can result in colitis.
Metabolic Disruption
A personalized diet that accounts for an individual’s metabolism is the safest way to lose weight. Such plans should be created by a qualified dietitian. When choosing a diet independently, select an option that allows for gradual weight loss—up to two kilograms per month. Sudden fluctuations in body weight can do more harm than good. With steady weight loss, the metabolism can adjust without negative effects, and muscles and skin are less likely to sag. In that case, the body will naturally tone up and overall well-being will improve.
Temporary Effects
The most popular modern diets attract new followers with their promise of immediate results: they claim to help you lose weight right away. However, quick results often produce only temporary outcomes. Losing 5 to 7 kilograms in a week or two can easily be followed by regaining the same amount (or more) within the same timeframe. Additionally, you may experience hormonal disruptions and metabolic disorders. It’s unlikely that a short-term improvement in appearance is worth potential health problems such as liver and bile duct disease, diarrhea, bloating, dark circles under the eyes, and facial wrinkles.
A Blow to Well-Being
A starving body lacks essential salts, vitamins, and minerals. Reducing the fat content in dairy products can hinder calcium absorption, which is crucial for healthy teeth and bones. Moreover, the active fluid loss promoted by many diets can wash away potassium and sodium through the kidneys, leading to physical ailments, low energy, reduced heart function, and cardiovascular problems. A lack of iron can result in anemia and cause issues with the skin, hair, and nails, often caused by restricting meat.
At-Risk Groups
Diets lasting more than five days can deplete the body of water-soluble vitamins, which the body cannot store. As a result, vision may decline, digestion may suffer, sleep can be disrupted, and the nervous system may weaken. People on such diets often show aggressive or depressed behavior. A shortage of carbohydrates can lead to decreased cognitive function, reduced productivity, and a generally low mood. To boost brain activity and cope with persistent headaches, people may need to compensate for dietary deficiencies by increasing glucose intake.
To Avoid Crashing
The secret to a successful diet is that it should be enjoyable. Base your meals on foods you like rather than foods your body dislikes. If you’re not fond of buckwheat, don’t make it a staple of your diet. Similarly, if root vegetables aren’t your thing, don’t force yourself into raw-food diets. To prevent binge eating during hunger pangs, stick to small, frequent meals so your efforts to manage weight don’t go to waste.
