Extreme diets are often appealing because they promise rapid weight loss. However, they are not sustainable and can cause health problems. These diets are usually very low in carbohydrates or fat, making them unbalanced and potentially dangerous. While they may lead to short-term weight loss, the weight is often regained when people go off the diet. Instead of extreme diets, a more balanced approach with a healthy, nutritious, and low-calorie diet combined with physical activity is recommended for sustainable weight loss and the prevention of health issues. Before starting any drastic diet or calorie restriction, it is important to consult a healthcare professional.

What You'll Learn
The dangers of extreme diets
Extreme diets are associated with several health risks and side effects. They are often unsustainable and can lead to a cycle of weight loss and weight gain, also known as "yo-yo dieting". This can contribute to insulin resistance and potentially Type 2 diabetes.
One of the main dangers of extreme diets is malnutrition, which can lead to atrophy of muscles throughout the body, including the heart. Extreme diets can also cause a range of side effects, including low energy, fatigue, irritability, bad breath, constipation, diarrhoea, and flatulence. In addition, extreme diets can increase the risk of developing gallstones due to changes in fat metabolism.
Another concern with extreme diets is their potential impact on bone health. For example, the paleo diet, which excludes dairy products, can make it difficult to get enough calcium, increasing the risk of osteoporosis. Similarly, avoiding starchy carbohydrates can lead to a lack of fibre and B vitamins, which can have negative consequences for digestive health.
Extreme diets can also be emotionally and mentally challenging. They may lead to feelings of restriction and deprivation, which can be difficult to sustain in the long term. This can contribute to a negative relationship with food and potentially lead to disordered eating behaviours.
Furthermore, extreme diets may not provide the expected results. While they may lead to initial weight loss, this is often due to a loss of water and muscle rather than fat. In the long term, extreme diets can set individuals up for metabolism problems, rebound weight gain, and life-threatening medical conditions.
It is important to note that weight loss should be approached with caution and under the guidance of a healthcare professional. Sustainable and healthy weight loss is typically achieved through balanced, nutritious diets and regular physical activity.

The military diet
The diet provides a set meal plan for breakfast, lunch, and dinner for the first 3 days, without snacks between meals. The total calorie intake starts at 1,400 on the first day and decreases to 1,100 on the third day. The diet is high in protein and low in fat, carbohydrates, and overall calories. It includes specific food combinations that are claimed to boost metabolism and burn fat. For example, it emphasizes the consumption of animal-based protein foods and grapefruit or baking soda mixed with water, which are said to reduce body fat. However, there is no scientific evidence supporting these claims.
During the 3-day phase, the military diet permits drinking water, herbal teas, and caffeinated coffee or tea twice per day without any sugar or creamers. The diet is flexible and allows substitutions as long as portions match the calorie count. For the remaining 4 days of the week, there are no strict rules, but a 1,500-calorie menu is provided for those who want to continue losing weight.
While the military diet may be beneficial for short-term weight loss, it may be challenging and potentially unsafe to maintain. It is not recommended for long-term weight loss as it does not promote positive habit changes. Most of the weight loss experienced is due to the loss of water, and severe calorie restrictions may lead to health issues. Before starting this diet, it is crucial to consult a healthcare professional.

The paleo diet
Protein Sources: Lean meats are a cornerstone of the paleo diet. Opt for grass-fed, organic beef, poultry, and pork. Game meats like venison and bison are also great choices. Fish and seafood should be wild-caught and varied, including salmon, tuna, trout, and shellfish. These provide essential omega-3 fatty acids.
Fruits and Vegetables: Fill your plate with a variety of colorful fruits and vegetables. Leafy greens like spinach, kale, and Swiss chard are packed with nutrients. Include other veggies like broccoli, cauliflower, carrots, and squash. For fruits, focus on lower-sugar options like berries, apples, citrus fruits, and melons.
Healthy Fats: Nuts and seeds, such as almonds, macadamia nuts, walnuts, sunflower seeds, and flaxseeds, are excellent sources of healthy fats and fiber. Avocados are another great option. Use olive oil, avocado oil, or coconut oil for cooking, as these are stable fats that can withstand higher temperatures.
Exclusions: Grains, legumes (including beans, peanuts, and soy products), and dairy are excluded from the paleo diet. These foods are considered to be modern inventions that our ancestors did not consume. Additionally, avoid processed foods, added sugars, and artificial sweeteners.
Meal Planning and Preparation: Success with the paleo diet often relies on careful meal planning and preparation. Stock your pantry and fridge with paleo-friendly foods. Prepare large batches of meals in advance so you always have something healthy and compliant to eat.
Snacking: When it comes to snacks, opt for paleo-friendly options like fruit with nut butter, hard-boiled eggs, sliced vegetables with guacamole, or homemade trail mix made with nuts and dried fruit.
Dining Out: When dining out, opt for grilled or broiled meats and seafood. Choose salads and vegetable sides. Avoid breaded or fried foods, and be mindful of sauces and dressings that may contain non-compliant ingredients.
Remember, while the paleo diet promotes a return to ancestral eating habits, it is still essential to prioritize variety, moderation, and overall nutritional balance. Consult with a healthcare professional or nutritionist to ensure that your diet meets all your nutritional needs and aligns with your specific health goals and restrictions.

The egg diet
There are several versions of the egg diet, including an egg-only or boiled egg diet. In the boiled egg diet, you eat a minimum of two to three eggs per day, along with lean proteins, some fats, and non-starchy fruits and vegetables. In one variation of the diet, all fruit except grapefruit is eliminated. In other variations, other fruits are acceptable. Starchy carbohydrates from grains or vegetables are avoided in most versions of the egg diet.
The boiled egg diet is extremely restrictive, incredibly low-calorie, and faddish. It is not a balanced, healthy diet. Eggs are healthy in moderation but not as your only or main food. The American Heart Association (AHA) says that healthy people can enjoy up to one egg per day, and older people with healthy cholesterol levels can have two.

The importance of exercise
While it may be tempting to drastically cut calories and restrict food groups to lose weight quickly, this approach can be dangerous and is not sustainable. Extreme diets can lead to a range of health issues, including muscle loss, bone density loss, anaemia, constipation, fatigue, and low energy.
Instead, a balanced approach to weight loss that includes both dietary changes and regular exercise is recommended. Exercise is crucial as it helps burn calories, preserve lean muscle, and improve overall health. It is particularly beneficial for heart health, building muscle, and enhancing mental well-being.
To build muscle, for example, it is not enough to simply consume a high-protein diet. Progressive overload resistance training is necessary to challenge the muscles and promote growth. Similarly, adequate protein intake is essential for those engaging in strength training to support muscle repair and growth.
Additionally, physical activity, especially regular exercise, improves brain-related functions and outcomes. It also plays a significant role in maintaining weight loss. Engaging in exercise helps to create a calorie deficit, which is necessary for weight loss, and it supports the maintenance of a healthy weight by increasing the body's energy expenditure.
It is recommended to aim for at least 150 minutes of moderate to vigorous exercise each week to promote overall health and well-being. Combining dietary changes with exercise optimizes health, enhances quality of life, and helps to prevent future health problems associated with obesity, such as type 2 diabetes, cardiovascular diseases, and certain cancers.
