A healthy diet is one that does not contain excess calories, free sugars, or saturated fats, and instead contains a balance of nutrients. The exact make-up of a healthy diet varies depending on individual characteristics, cultural context, and locally available foods. However, some diets that constitute no excess are considered unhealthy due to their extreme restrictions, such as the grapefruit diet, the Beverly Hills diet, and the cabbage soup diet. On the other hand, diets such as the Mediterranean diet, the DASH diet, and the MIND diet are considered healthy because they encourage the consumption of health-promoting foods and the avoidance of unhealthy options.

What You'll Learn
Avoid excess calories and sugars
A diet with no excess involves avoiding excess calories and sugars. While calorie counting is not the best way to lose weight, as it does not always yield uniform results, it is still important to be mindful of calorie intake. To lose weight, you need to eat fewer calories than you burn.
To avoid excess calories, it is recommended to watch your portion sizes, as large portions can lead to overeating. You can try weighing and measuring your portions or using smaller plates. When eating out, consider sharing a meal or ordering a half portion. Additionally, be mindful of high-calorie dressings, sauces, and condiments, as they can add significant calories to your meal.
Another way to cut calories is to limit your consumption of ultra-processed foods. Research suggests that ultra-processed foods contribute to a significant amount of the added sugars in the average diet and may spur people to consume more calories compared to eating unprocessed foods. Therefore, try to cook from scratch whenever possible to have more control over the ingredients and avoid added sugars.
To specifically target excess sugars, it is important to read nutrition labels and be aware of the various names for added sugars. The World Health Organization recommends less than 5% of calories from added sugars for optimal health. Instead of consuming sugary drinks, opt for water, unsweetened beverages, or diet drinks. Additionally, curb your sugar cravings by incorporating more protein-rich whole foods into your diet, such as meat, fish, eggs, and nuts.
In summary, avoiding excess calories and sugars involves portion control, reducing processed foods, cooking from scratch, reading nutrition labels, opting for low-sugar beverages, and incorporating more protein into your diet. These strategies can help reduce excess calories and sugars, promoting a healthier diet and potentially contributing to weight loss.

Eat more fruits and vegetables
Eating more fruits and vegetables is a great way to improve your health and maintain a well-balanced diet. Here are some reasons why you should eat more fruits and vegetables:
Nutritional Value
Fruits and vegetables are packed with vitamins and minerals, including vitamins A, C, and E, as well as magnesium, zinc, phosphorus, and folic acid. They are also a great source of potassium, one of the most important minerals for your health. By eating a variety of colourful fruits and vegetables, you can ensure you get a diverse range of nutrients.
Fiber Content
Most fruits and vegetables are rich in fiber, which can help with satiety, boost gut health, and aid in weight management. High-fiber fruits include raspberries, pears, apples, and pumpkin, while fiber-rich vegetables include artichokes, green peas, broccoli, and cauliflower.
Low in Calories and Fat
Fruits and vegetables are typically low in calories and fat, allowing you to eat larger portions without worrying about excess calorie or fat intake. This can be beneficial for those looking to maintain or lose weight.
Protection Against Diseases
Many fruits and vegetables contain phytochemicals, biologically active substances that can help protect against certain diseases. For example, adding more fruits and vegetables to your diet can lower your risk of type 2 diabetes, stroke, heart disease, high blood pressure, and cancer.
Weight Management
The low-calorie, low-fat nature of fruits and vegetables, coupled with their high fiber content, makes them ideal for weight management. They can help you feel fuller for longer without consuming excess calories, supporting a healthy weight.
Reducing Inflammation and Lowering Cholesterol
Fruits and vegetables are low in saturated fat, salt, sugar, and sodium, which can help reduce inflammation and lower cholesterol levels. This can lead to improved heart health and a reduced risk of cardiovascular diseases.
Creative and Delicious Options
Fruits and vegetables offer a variety of flavours, textures, and preparation methods, allowing you to get creative in the kitchen. Whether you enjoy strong flavours like onions and peppers, or milder options like mushrooms and corn, there is something for everyone.
Incorporating more fruits and vegetables into your diet can be easy and enjoyable. You can add fruits to your cereal, yogurt, or oatmeal, or simply eat them whole. For vegetables, try adding them to soups, choosing vegetable sticks and dips instead of chips, or preparing snack bags with dried vegetables and nuts.

Limit saturated and trans fats
A healthy diet helps protect against malnutrition and noncommunicable diseases (NCDs) such as diabetes, heart disease, stroke, and cancer. It is important to note that the exact composition of a healthy and balanced diet varies depending on individual characteristics, cultural context, and locally available foods. However, limiting saturated and trans fats is generally recommended to maintain a healthy diet without excess.
Saturated fats are common in the American diet and are solid at room temperature. They are found in red meat, whole milk, other whole-milk dairy foods, cheese, coconut oil, and many commercially prepared baked goods. Saturated fats can increase total cholesterol and tip the balance towards more harmful LDL cholesterol, which can lead to blockages in arteries. Therefore, most nutrition experts recommend limiting saturated fat to less than 10% of total energy intake or daily calories.
Trans fats, on the other hand, are considered the worst type of dietary fat. They are generated by an industrial process that adds hydrogen to liquid vegetable oils to solidify them and prevent rancidity. Trans fats have no known health benefits, and even small amounts can be harmful. For every 2% of daily calories from trans fat, the risk of heart disease increases by 23%. To reduce the risk of heart disease, the American Heart Association recommends limiting trans fat intake and suggests that adults who need to lower their LDL cholesterol reduce their consumption of saturated fat to 5 to 6% of total calories.
To limit saturated and trans fats in your diet, it is important to read nutrition labels and choose foods without partially hydrogenated or hydrogenated vegetable oils or saturated fat. Look for processed foods made with unhydrogenated oils and use soft margarine instead of butter. Limit commercially fried foods, baked goods, doughnuts, cookies, crackers, muffins, pies, and cakes, as these often contain trans fats. Instead, opt for a dietary pattern that emphasizes fruits, vegetables, whole grains, low-fat dairy products, poultry, fish, and nuts.
It is worth noting that some fad diets, such as keto, may lead to an excess of saturated fat intake due to a high consumption of meat and cheese. Therefore, it is important to consult with a medical team or registered dietitian to ensure a well-balanced and nutritious diet.

Exercise regularly and socialise
A healthy diet is one that helps to protect against malnutrition and noncommunicable diseases (NCDs) such as diabetes, heart disease, stroke, and cancer. However, there is no one-size-fits-all diet that is a panacea for everyone to lose weight or become healthier. A healthy diet should be balanced and diverse, and its exact makeup will vary depending on individual characteristics such as age, gender, lifestyle, and degree of physical activity.
Regular exercise and socialising are important components of a healthy lifestyle, and can help to prevent the development of obesity and NCDs. Physical inactivity is a leading risk factor for NCD mortality, with insufficiently active people having a 20% to 30% increased risk of death compared to those who are sufficiently active. Regular physical activity provides significant physical and mental health benefits for both adults and children. In adults, it contributes to the prevention and management of NCDs such as cardiovascular diseases, cancer, and diabetes, and can reduce symptoms of depression and anxiety, enhance brain health, and improve overall well-being. In children and adolescents, physical activity promotes bone health, encourages healthy growth and development of muscles, and improves motor and cognitive development.
To incorporate more physical activity into your lifestyle, it is helpful to first identify any personal barriers you may have to regular exercise. Common barriers include lack of time due to work, family obligations, and other daily life commitments. To overcome these barriers, try monitoring your activities for a week and identifying at least three 30-minute slots that could be used for physical activity. Select activities that can easily fit into your routine, such as walking in your neighbourhood, climbing stairs at your office, or exercising while watching TV. Joining a group or taking a class can also increase your exercise time and health benefits, and provide opportunities for socialising.
Exercising with others can help to keep you motivated and committed to your fitness goals. Share your fitness and health goals with friends and family, and invite them to participate in physical activities with you. Joining a local club or community group, such as a walking club or beginner group exercise class, can also help you to find people with similar goals and offer support. Socialising with others who share your interests in fitness and health can help to keep you accountable and provide additional motivation to stay active.

Avoid fad diets
Fad diets are typically short-term, weight-loss plans that involve drastic changes to a person's normal eating habits. They are often restrictive, promoting the elimination of certain foods or entire food groups, and can be harmful to your health.
Fad diets are usually tempting because they promise quick and easy weight loss, but they are hard to stick to and can lead to an unhealthy relationship with food. They often involve extreme and rapid changes to your food consumption, such as severe calorie restriction, which can be unhealthy and unrealistic to maintain in the long term. While you may initially lose weight, it is often due to the loss of water or lean muscle rather than fat. Once you return to your normal eating habits, you will likely gain back the weight, and possibly even more.
Fad diets can also cause nutritional deficiencies and lead to a host of health problems, including negatively impacting your hormonal health and metabolism. They can be restrictive, causing cravings and making eating a chore, and can be isolating, making it difficult to dine with others. In addition, marketed supplements that are often recommended with fad diets can cause side effects or interactions with medications.
Instead of following a fad diet, it is important to develop healthy lifestyle choices, including nutritious eating, regular physical activity, and balancing calorie consumption with the number of calories your body uses. Focus on making gradual changes that you can maintain in the long term, such as limiting your consumption of sugary foods and drinks, and eating more fruits, vegetables, legumes, nuts, and whole grains. Seek guidance from a trained professional, such as a nutritionist, to find a diet that is tailored to your unique needs and circumstances.
Remember, there is no magic pill or food to help you lose weight. Healthy weight loss takes time and balance, and it is important to be mindful of your eating habits and develop a healthy relationship with food.
