This includes fruits, vegetables, legumes, meat, fish, eggs, milk, and staples like cereals and starchy tubers. In addition, consuming healthy fats, avoiding simple sugars, and limiting sodium intake are crucial.

What You'll Learn
Eating a balanced diet
Include Plenty of Fruits and Vegetables
Eat at least 5 portions of a variety of fruits and vegetables every day. They can be fresh, frozen, canned, dried, or juiced. Fruits and vegetables are excellent sources of essential vitamins, minerals, fibre, and antioxidants. Aim for colour and variety, as different-coloured produce provides a full range of nutrients. Dark, leafy greens, in particular, are highly nutritious.
Choose Whole Grains and Starchy Foods
Include starchy carbohydrates and whole grains in your diet. They should make up just over a third of your meals. Examples include potatoes, bread, rice, pasta, cereals, whole wheat, barley, quinoa, oats, and brown rice. Choose higher-fibre or wholegrain varieties, as they contain more fibre and can help you feel fuller for longer.
Incorporate Protein Sources
Consume adequate protein by including foods such as meat, eggs, fish, beans, nuts, and legumes in your diet. If you follow a vegan diet, ensure you get plant-based sources of protein like tofu and beans. Dairy products, such as milk, cheese, and yoghurt, are also good sources of protein and calcium, which is essential for bone health. Opt for lower-fat and lower-sugar dairy options when possible.
Select Healthy Fats
Include some fat in your diet, but focus on unsaturated fats found in oils and spreads. Oily fish, such as salmon, are good sources of omega-3 unsaturated fats, which may help prevent heart disease. Nuts are also high in healthy fats, but eat them in moderation due to their high-calorie content. Limit your intake of saturated fats, as they can increase your risk of heart disease by raising cholesterol levels.
Stay Hydrated
Drink plenty of fluids to stay hydrated. The government recommends consuming 6 to 8 glasses of fluid daily, in addition to the water content of the food you eat. Water, lower-fat milk, and lower-sugar drinks are healthier choices. Avoid sugary soft drinks, fruit juices, and smoothies, as they are high in calories and sugar, which can contribute to weight gain and tooth decay.
Remember, eating a balanced diet is about combining different food groups and nutrients while paying attention to portion sizes and your individual needs. It's always a good idea to consult with a healthcare professional or a registered dietitian for personalised advice.

Intermittent fasting
There are several ways to do intermittent fasting, including daily time-restricted fasting and alternate-day fasting. The 16/8 method, a type of daily time-restricted fasting, involves eating only during an eight-hour window and fasting for the remaining 16 hours of the day. Another daily time-restricted fasting method is the 5:2 approach, where individuals eat normally for five days of the week and restrict themselves to one 500-600 calorie meal for the remaining two days.
Alternate-day fasting involves eating a normal, healthy diet one day and then either completely fasting or consuming a small meal of fewer than 500 calories the next day. This method is about as effective as a typical low-calorie diet for weight loss.
While intermittent fasting may be a useful tool for weight loss and improving certain health conditions, it is not suitable for everyone. It is not recommended for individuals under 18, those with a history of disordered eating, or those who are pregnant or breastfeeding. Additionally, athletes may find it challenging to fuel their active lifestyles with this approach. If you have diabetes or other medical issues, it is important to consult your healthcare provider before starting intermittent fasting.
It is also crucial to maintain a healthy diet during the eating periods of intermittent fasting. Meals should be composed of quality, healthy ingredients, such as fruits, vegetables, whole grains, low-fat dairy, and lean protein. It is important to avoid overeating during the eating windows and to ensure adequate nutrient intake.

Mediterranean diet
The Mediterranean diet is based on the traditional foods of countries that border the Mediterranean Sea, including France, Spain, Greece, and Italy. It is rich in fruits, vegetables, whole grains, legumes, and heart-healthy fats such as olive oil, and it includes a moderate intake of dairy products and seafood. The Mediterranean diet is adaptable and easy to stick to, and it provides a balance of nutrients. It does not include highly processed foods, added sugars, or refined carbohydrates.
There are no concrete rules for following the Mediterranean diet, but some general guidelines can help incorporate its principles into your daily routine. For example, it is recommended to eat an abundance of fruits and vegetables, as well as legumes, whole grains, and seafood. It is also suggested to limit red meat intake and choose smaller portion sizes for meat, using it as a garnish instead of a main course. Additionally, you can drink a low to moderate amount of red wine, preferably with a meal.
The Mediterranean diet has been recognised for its health benefits, including weight management, heart health, and blood sugar stabilisation. It has been named the "Best Overall Diet" by U.S. News & World Report since 2018 and ranked #1 for ease of following, as well as being the best diet for diabetes, high cholesterol, gut health, mental health, and inflammation. Research suggests that people living in Mediterranean regions tend to have a lower risk of chronic conditions compared to those following a standard American diet.
A sample menu for a week of meals on the Mediterranean diet includes Greek yogurt with strawberries and chia seeds for breakfast, a whole-grain sandwich with hummus and vegetables for lunch, and a tuna salad with greens and olive oil, or a Mediterranean pizza made with whole wheat pita bread, cheese, vegetables, and olives for dinner. It is important to consume all foods in moderation and adjust portions according to your needs and preferences.
The Mediterranean diet is a suitable option for those seeking to improve their health and protect against chronic diseases. It offers a well-balanced approach to nutrition, emphasising healthy plant-based foods, moderate intake of dairy and seafood, and the enjoyment of delicious flavours and healthy fats.

Healthy breakfast
Eating a healthy breakfast can help you maintain energy, keep hunger at bay, and lose weight. A nutritious breakfast can also provide important nutrients like vitamins, minerals, and fibre, which play a role in weight control. A healthy breakfast should include a mix of protein, complex carbohydrates, fibre, and healthy fats to keep you full and fuelled for the day.
There are plenty of healthy breakfast options that can help you lose weight. For example, eggs are a true powerhouse of nutrition, rich in protein and important vitamins and minerals such as selenium, riboflavin, B12, and vitamin A. Research has found that eggs may help reduce appetite when eaten for breakfast, giving weight loss a boost. Another easy breakfast option is egg muffins, which can be made by mixing eggs with chopped vegetables and a small amount of cheese, then baking the mixture in muffin tins.
Oats are another healthy breakfast option, as they are low in calories but high in fibre and protein, which impact appetite and weight control. Chia seeds are also an excellent breakfast supplement, as they are high in fibre and can absorb water to form a gel, which expands in the stomach to help you feel fuller for longer.
If you prefer a savoury breakfast, try a wrap stuffed with sautéed veggies and scrambled tofu, providing over 9 grams of plant-based protein per 3-ounce serving. Nuts are another good option to sprinkle on top of oats or yoghurt, as they provide the perfect balance of fibre, protein, and heart-healthy fats. However, remember that nuts are also calorie-dense, so limit your intake to about one ounce (28 grams) at a time.
In addition to these specific food options, it is important to follow general healthy eating guidelines when preparing breakfast. This includes choosing unsaturated fats over saturated fats to lower cholesterol and reduce the risk of heart disease, and limiting added sugars and salt, which can increase the risk of obesity, tooth decay, and heart disease.
