Losing weight is a common goal, but it rarely comes easy. Fast weight loss is possible, but it is important to do it in a safe and sustainable way. Fad diets are often unsustainable and can lead to regaining weight later on. Instead, a permanent shift towards healthier eating habits and lifestyle changes is recommended. This includes eating a healthy, balanced diet with a variety of fruits and vegetables, plant-based dishes, drinking plenty of water, and increasing physical activity. Intermittent fasting and low-calorie diets can also aid weight loss, but it is important to proceed with caution and consult a healthcare professional. Ultimately, a combination of dietary changes, exercise, and healthy habits will help achieve weight loss goals and improve overall health.
Characteristics of Fast Weight Loss Diets
| Characteristics | Values |
|---|---|
| Calorie Intake | Very low-calorie diets (VLCD) are recommended for adults with obesity and are often used before weight-loss surgery. VLCDs allow 1,200 to 1,500 calories for women and 1,500 to 1,800 for men. |
| Time Period | Fast weight loss diets are typically short-term and not recommended for more than 12 weeks. |
| Health Risks | Rapid weight loss may not be safe for everyone and can lead to health complications like gallstones, dehydration, and nutritional deficiencies. |
| Regain Weight | People who lose weight quickly are more likely to regain the weight over time compared to those who lose weight slowly. |
| Intermittent Fasting | Intermittent fasting involves short-term fasts and eating within a shorter daily window. Popular methods include the 5:2 diet, alternate-day fasting, and the 16/8 method. |
| Physical Activity | Increasing physical activity is recommended alongside dietary changes to burn more calories and promote weight loss. |
| Sustainable Habits | Embracing permanent healthy eating habits and lifestyle changes is more effective for long-term weight loss than restrictive fad diets. |
| Food Choices | Diets for fast weight loss often emphasize natural, unprocessed, and plant-based foods, with a focus on fruits and vegetables, healthy oils, and water. |

What You'll Learn
Intermittent fasting
There are different forms of intermittent fasting, some more extreme than others. The 16:8 method involves fasting for 16 hours and eating only during an 8-hour window, typically from noon to 8 pm. Another method is the 5:2 diet, where you eat normally for five days of the week and fast for the remaining two, eating only 500-600 calories on those days. Alternate-day fasting is another option, where you fast every other day and eat a typical diet on non-fasting days.
During a fast, water and zero-calorie beverages such as black coffee and tea are permitted. It is important to eat healthily during non-fasting periods, focusing on whole foods over packaged and processed ones. While intermittent fasting can be a useful tool for weight loss, it may not be suitable for everyone, and it is always best to consult a doctor before making drastic changes to your diet.

Low-calorie diets
To maintain a balanced diet while reducing calories, it is recommended to fill half of your plate with non-starchy vegetables, such as leafy greens, cucumbers, and bell peppers. Include a lean protein source like grilled chicken, turkey, tofu, or fish to stay satiated and maintain muscle mass. Add healthy fats like avocado, olive oil, or nuts for essential nutrients and flavor. Keep carbohydrates to a quarter of your plate, opting for whole grains, quinoa, or sweet potatoes to provide steady energy levels.
It is important to note that low-calorie diets may not be more effective than more modest approaches in the long run. While they can lead to initial weight loss, it is essential to prioritize gradual improvements and lifestyle changes to maintain a healthy weight. Additionally, low-calorie diets should be complemented with physical activity, such as 30 minutes of moderate-intensity exercise most days of the week, to promote overall health and well-being.
Some people may find success in combining low-calorie diets with other methods such as intermittent fasting, where you consume meals within a shorter time window during the day. However, it is always recommended to consult with a healthcare professional or nutritionist before starting any diet to ensure it is safe and suitable for your individual needs.

Fad diets
- Atkins Diet: This is the most famous low-carb weight loss diet in the world. It claims to produce rapid weight loss without hunger. The modern Atkins program allows you to choose your carbohydrate goals, from 20 grams (mimicking the ketogenic diet), 40 grams, or 100 grams per day.
- Ketogenic Diet: This is a very low-carb, high-fat diet that aims to put your body into a state of ketosis. While it can be effective for weight loss, it may lead to an excess intake of saturated fat, which can increase the risk of heart disease.
- Paleo Diet: The paleo diet, short for the Paleolithic diet, is based on the diets that hunter-gatherers ate thousands of years ago. It restricts many foods, including dairy, legumes, grains, and processed foods, and encourages the consumption of a wide variety of plant and animal foods.
- Zone Diet: This diet claims that a strict ratio of protein, fat, and carbs is required for optimal weight loss and overall health. It specifies that your calorie intake should be made up of 30% lean protein, 30% healthy fat, and 40% high-fiber carbs.
While some fad diets may produce weight loss, they are often not sustainable long-term. They can be extremely restrictive, causing followers to miss out on certain food groups or nutrients, which can deplete the body. Additionally, they may lack physical activity guidelines, promote short-term changes instead of lifelong sustainable goals, and have questionable nutritional adequacy.

Mediterranean diet
While the Mediterranean diet is not a weight loss system, it is associated with decreased weight and a smaller waist circumference. The Mediterranean diet is based on the eating habits of people living in countries bordering the Mediterranean Sea. It is recognised as one of the healthiest and most delicious ways to eat.
The Mediterranean diet is rich in healthy fats, fruits, vegetables, whole grains, legumes, and nuts. It also includes moderate amounts of red wine, coffee, and tea. The diet discourages refined grains, added sugar, trans fats, and processed foods.
- Lunch is the main meal of the day and is consumed between 1 pm and 3 pm. Eating a larger meal earlier in the day reduces the risk of overeating later.
- A vegetable dish cooked in olive oil and tomato is a satisfying and healthy option.
- The Mediterranean diet is not restrictive, but you need to be mindful of portion sizes and calories. For example, one teaspoon of olive oil contains 80 calories.
- The Mediterranean diet pyramid can be a helpful guide. It recommends eating smaller amounts of meat and desserts compared to other food groups.
- The diet can be adapted to be vegetarian, vegan, or gluten-free.
- The Mediterranean diet may be better for weight loss than a low-fat diet. Research has shown that people lost slightly more weight on the Mediterranean diet compared to a low-fat diet.
- The diet has also been associated with a healthy weight in children and pregnant women.

Healthy eating and lifestyle changes
Losing weight in a healthy way involves a combination of healthy eating and lifestyle changes. It is important to remember that there is no one-size-fits-all plan for healthy eating, and the best approach is one that works for you specifically, makes you feel good, and keeps you motivated.
A good place to start is to eat more good-for-you foods like vegetables, fruits, whole grains, and lean protein. The Mediterranean diet, for example, may support weight loss and bone health. It consists of natural unprocessed foods and plenty of plant-based dishes. It is also beneficial to cut back on carbohydrates and alcohol, as alcohol use could contribute to dementia by damaging the brain.
Mindful eating is another practice that can aid weight loss. This involves paying attention to how and where you eat food, such as sitting down at a table without any distractions. This can help you enjoy the food and increase your awareness of what you are eating.
In addition to healthy eating, physical activity is important for weight loss and overall health. Even simple devices like a pedometer can be useful for tracking physical activity. However, it is important to consult a doctor or registered dietitian to determine the right exercise routine and diet plan for your specific needs and to ensure you are getting the necessary nutrients.
Finally, getting enough sleep is crucial when trying to lose weight. Research shows that poor sleep can lead to snacking on foods high in fat and carbohydrates and consuming more calories overall. Therefore, getting adequate, good-quality sleep can support your weight loss journey.
