The quest for weight loss has led many to try extreme diets, from keto and juice cleansing to the shocking jaw wiring diet, where the jaw is literally wired shut. But do these diets deliver, or do they put health at risk? Let's explore the facts behind these trendy diets.
The keto diet, characterized by low carbohydrate and high fat intake, may lead to short-term weight loss, but its negative impact on gut health and nutrient deficiencies raises concerns. The high fat intake and low carbohydrate consumption can disrupt gut health, while the diet often lacks essential nutrients like fibre, vitamins, and minerals.
Mbali Mapholi, Consultant Dietician in private practice, warns that the keto diet can lead to nutrient deficiencies, kidney problems, increased risk of heart disease, and disrupted gut health, causing digestive issues and other health concerns."
Furthermore, seemingly healthy keto options like sugar-free ice cream, keto protein bars, keto smoothie bowls, and sugar-free energy drinks can be detrimental to overall health due to their high content of artificial sweeteners, highly processed ingredients, preservatives, and artificial flavourings.
The juice cleansing diet, which involves consuming only juice made from fruits and vegetables, has been marketed as a way to detoxify the body and promote weight loss. However, there is no scientific evidence to support these claims, and the diet often lacks essential nutrients like protein, healthy fats, and fibre.
Furthermore, the high sugar content of juice can disrupt gut health, and added supplements can be unnecessary and even harmful. Rather than relying on juice cleansing, a balanced diet that includes a variety of whole foods is a more sustainable and healthy approach to nutrition
The sugar-free diet, which involves eliminating or drastically reducing sugar intake, may seem like a healthy choice, but it can have unintended consequences. Artificial sweeteners used as sugar substitutes can confuse the body's natural ability to regulate blood sugar, leading to metabolic problems.
Sugar-free foods like baked goods, diet sodas, and energy drinks can contain unhealthy ingredients like refined flour, artificial sweeteners, and excessive caffeine. Rather than relying on a sugar-free diet, a balanced diet that includes whole, nutrient-dense foods is a more sustainable and healthy approach to nutrition.
The raw food diet, which consists mainly of uncooked and unprocessed foods, has been promoted as a way to promote weight loss and improve energy. However, there is limited scientific evidence to support these claims, and a raw food diet can be low in certain nutrients and pose food safety concerns.
Foods like raw milk, unsprouted grains, and raw or undercooked meat can contain bacteria and other contaminants that can lead to foodborne illnesses. Rather than relying on a raw food diet, a balanced diet that includes a variety of cooked and raw foods can provide all the necessary nutrients for optimal health.
The jaw wiring diet, which involves wiring the jaw shut to prevent solid food intake, is a highly restrictive and potentially harmful dieting method. This diet can lead to severe calorie restriction, nutrient deficiencies, and dental and jaw problems.
Mbali adds that jaw wiring for weight loss can lead to severe nutrient deficiencies, muscle loss, digestive problems, and mental health issues like anxiety and depression, with long-term effects on oral health and social well-being.
Furthermore, it can contribute to eating disorders like anorexia nervosa. Rather than resorting to such extreme measures, a balanced diet combined with regular exercise and a healthy lifestyle is a more sustainable and healthy approach to weight loss.
