Eating a healthy, balanced diet is one of the most important things you can do to protect your health. A healthy diet can help lower your risk of heart disease, stroke, diabetes and certain types of cancer. It can also help you maintain a healthy weight. The key to a healthy diet is to eat the right amount of calories for your activity level, so you balance the energy you consume with the energy you use. It's also important to eat a wide range of foods to ensure your body is getting all the nutrients it needs. This includes eating plenty of fruits and vegetables, which are good sources of vitamins, minerals and fibre. Whole grain foods are also a great source of fibre, as well as protein and B vitamins. When it comes to weight loss, some people try intermittent fasting, which involves switching between fasting and eating on a regular schedule. However, it's important to note that a healthy diet is not a fad or a quick fix; it's a permanent shift towards healthier eating habits.
Characteristics of a Healthy Diet
| Characteristics | Values |
|---|---|
| Calorie intake | The number of calories consumed should balance the energy used. Men should have around 2,500 calories a day, and women should have around 2,000 calories a day. |
| Starchy carbohydrates | Should make up just over a third of the food you eat. Choose higher-fibre or wholegrain varieties, such as wholewheat pasta, brown rice, or potatoes with their skins on. |
| Fat | Choose foods with unsaturated fats, such as vegetable oils and spreads, oily fish, and avocados. Meat should be lean, and skinless where possible, to reduce saturated fat intake. |
| Sugar | Regularly consuming sugary foods and drinks increases the risk of obesity and tooth decay. Avoid sugary drinks, and limit fruit juice and smoothies to small amounts. |
| Salt | Adults and children aged 11 and over should eat no more than 6g of salt per day. |
| Dairy | Dairy products are a good source of protein and calcium. Choose lower-fat and lower-sugar options, such as semi-skimmed milk and low-fat yoghurt. |
| Plant-based foods | Eat plenty of fruits and vegetables, aiming for at least 5 portions per day. Choose brightly coloured produce, especially orange and dark green vegetables. |
| Fluids | Drink plenty of water and lower-fat milk to stay hydrated. Avoid sugary drinks. |
| Intermittent fasting | This involves fasting for a certain number of hours each day or a couple of days a week. It can aid weight loss and provide other health benefits, but it is not suitable for everyone. Consult a healthcare professional before starting. |

What You'll Learn
Intermittent fasting
One popular method is the 16:8 method, which involves fasting for 16 hours and restricting eating to an eight-hour window. Some experts recommend females start with a 14-hour fast and gradually increase to 16 hours, while males can begin with a 16-hour fast. People usually finish their dinner by 8 p.m. and skip breakfast the next day, not eating again until noon. Another approach is the 5:2 method, which involves eating normally for five days and restricting calorie intake for the remaining two days.
During eating periods, it is important to make nutritious choices. The Mediterranean diet is often recommended, which includes leafy greens, healthy fats, lean protein, and complex, unrefined carbohydrates such as whole grains. Choosing nutrient-dense foods that are high in fibre, vitamins, and minerals can help keep blood sugar levels stable and prevent nutrient deficiencies.

Eat a balanced diet
Eating a balanced diet is one of the most important things you can do to protect your health. Eating a healthy, balanced diet can help you maintain a healthy weight and lower your risk of heart disease, stroke, diabetes and certain types of cancer.
The key to a healthy diet is to eat the right amount of calories for your activity level. If you eat or drink more than your body needs, you will put on weight, as the extra energy is stored as fat. If you eat and drink too little, you will lose weight. It is recommended that men have around 2,500 calories a day and women should have around 2,000 calories a day. Most adults in the UK are eating more calories than they need.
It is also important to eat a wide range of foods to ensure your body is getting all the nutrients it needs. A healthy diet should include foods from the five main food groups:
- Fruit and vegetables: These should make up just over a third of the food you eat each day. It is recommended to eat at least five portions of a variety of fruit and vegetables every day. They can be fresh, frozen, canned, dried or juiced.
- Starchy carbohydrates: These should also make up just over a third of the food you eat. They include potatoes, bread, rice, pasta and cereals. Choose higher-fibre or wholegrain varieties where possible.
- Protein: This includes beans, pulses, fish, eggs, meat and other protein sources. Eat some form of protein every day and try to eat at least two servings of fish each week.
- Dairy: Milk and dairy foods, such as cheese and yoghurt, are good sources of protein and calcium, which helps keep your bones healthy. Go for lower-fat and lower-sugar products where possible. Dairy alternatives, such as soya drinks, are also included in this food group.
- Fats and oils: All types of fat are high in energy and should be eaten in small amounts. It is important to get most of your fat from unsaturated oils and spreads, as too much saturated fat can increase your risk of heart disease.
In addition to the above, it is important to drink plenty of fluids to stay hydrated. The government recommends drinking 6 to 8 glasses of fluid every day, in addition to the fluid you get from food. Water, lower-fat milk and lower-sugar drinks are healthier choices. Try to avoid sugary soft and fizzy drinks, as they are high in calories.

Exercise regularly
Regular exercise is essential for maintaining a healthy weight and reducing your risk of serious health conditions. It is also important for your overall health and wellbeing. Being overweight or obese can lead to health conditions such as type 2 diabetes, certain cancers, heart disease, and stroke. Being underweight can also affect your health.
The NHS recommends that adults get at least 150 minutes of moderate-intensity activity, such as brisk walking or cycling, every week. You can also do 75 minutes of vigorous-intensity activity, such as running or swimming, or a combination of both. It is also important to incorporate strength exercises that work on the major muscle groups, such as legs, hips, back, abdomen, chest, shoulders, and arms, at least two days a week.
If you are new to exercise, start slowly and gradually increase the duration and intensity of your workouts. It is important to find an exercise routine that you enjoy and can stick to. There are many different types of exercise to choose from, such as walking, jogging, cycling, swimming, dancing, or team sports. You can also try high-intensity interval training (HIIT), which involves short bursts of intense activity followed by brief periods of rest.
In addition to structured exercise, try to incorporate more movement into your daily routine. For example, take the stairs instead of the elevator, walk or cycle to work, or get off the bus one stop early. You can also try standing or walking while taking phone calls or doing household chores during commercial breaks when watching TV.
It is important to listen to your body and not overdo it. Make sure to rest when needed and give your body time to recover. It is also crucial to stay hydrated, especially if you are exercising in hot weather or for extended periods. Drink plenty of water and consider carrying a reusable water bottle with you.
If you have any health conditions or concerns, it is always best to consult with your doctor or a healthcare professional before starting a new exercise routine. They can advise you on the types and amounts of exercise that are safe and suitable for you.

Avoid ultra-processed foods
Intermittent fasting is a popular eating plan that involves switching between fasting and eating on a regular schedule. It is a way to manage your weight and prevent or even reverse some forms of disease.
When it comes to eating healthy, it is important to avoid ultra-processed foods. Ultra-processed foods are industrial formulations with five or more ingredients that are rarely found in a home kitchen. They are heavily processed during production and are often high in salt, sugar, and saturated fat. These foods are typically found in the center of grocery stores, in fast-food restaurants, and gas station mini-marts. They are usually packaged and have a long shelf life.
The overconsumption of ultra-processed foods has been linked to adverse health outcomes, including an increased risk of obesity, heart disease, cancer, and type 2 diabetes. A review published in the British Medical Journal found that the consumption of ultra-processed foods was associated with a higher risk of premature death.
To avoid ultra-processed foods, it is recommended to stick to traditional, unprocessed, or minimally processed foods. For example, buying a block of cheddar cheese and slicing it yourself is healthier than buying pre-sliced cheese, which is likely to be ultra-processed. Similarly, choosing whole-grain cereals and breads is healthier than opting for refined flour products, even though they may fall into the same NOVA category.
It is important to note that not all processed foods are harmful, and some can even be beneficial. For example, pre-chopped vegetables and frozen chopped fruit are forms of processed foods that can be convenient and nutritious. However, it is generally recommended to limit the consumption of ultra-processed foods and opt for more natural, whole food options whenever possible.

Drink water
Drinking water is an essential part of a healthy diet and can also help with weight loss. Firstly, drinking water can help reduce your appetite and make you feel fuller for longer. This is because water takes up space in your stomach, triggering a signal to your brain that you are full and satisfied. In fact, you might think you are hungry when you are actually thirsty, so drinking a glass of water before reaching for a snack is a good way to curb unnecessary eating.
Drinking water can also help you burn more calories. Water has been shown to stimulate thermogenesis, or heat production, in the body, especially when chilled. The body has to expend energy to warm the fluid to body temperature, and the more energy expended, the faster your metabolism. Drinking water can also help your body break down fat without raising your blood sugar or insulin, which also aids weight loss.
Staying hydrated is also key to maintaining your blood's volume and ensuring your body can effectively regulate its temperature. When you are dehydrated, your body cannot correctly remove waste, and you are more prone to heat exhaustion. Drinking water also facilitates the removal of waste as it keeps stools soft, and it helps the kidneys to filter toxins and waste while retaining essential nutrients and electrolytes.
Drinking water is also a healthier choice than many other drinks. Replacing sugary drinks with water will help lower your sugar and calorie intake. However, it is important to note that while drinking water can help with weight loss, it is not a magic solution and should be combined with other healthy lifestyle choices.
