Consult a doctor or dietitian to determine if you need to lose weight and, if so, how to do so healthily
If you are 12 and thinking about losing weight, it is important to consult a doctor or a dietitian. They will be able to tell you if you need to lose weight and advise you on how to do so healthily.
Your doctor will consider many factors, such as your weight, height, BMI-for-age percentile, and whether you have any weight-related health problems, such as high blood pressure or high cholesterol. They will also take into account your family history of obesity and related health issues.
Based on these factors, your doctor or dietitian will be able to advise you on a safe and healthy weight loss plan, if needed. This may include recommending a weight-loss plan tailored to your needs or referring you to a weight-management specialist or registered dietitian. They may also suggest weight-management medicines or, in some cases, weight-loss surgery for teens over the age of 13.
However, it is important to remember that treatments such as medicines and surgery should be accompanied by lifestyle changes. This includes adopting healthier habits, such as following a healthy eating plan, getting regular physical activity, and getting enough sleep.
A doctor or dietitian can provide guidance on specific dietary and lifestyle changes. This may include increasing your intake of fruits and vegetables, choosing whole grains, reducing your consumption of sugary drinks, and being active every day. They can also advise you on appropriate portion sizes and the importance of home-cooked meals.

Focus on eating whole, unprocessed foods and avoid unhealthy snacks high in fat, sugar, or salt
If you are 12 and thinking about going on a diet, it's important to focus on healthy habits rather than restrictive fad diets. This means eating nutritious whole foods and avoiding unhealthy snacks that are high in fat, sugar, or salt.
Whole foods are those that are minimally processed or not processed at all, such as fresh fruits and vegetables, nuts, seeds, and legumes. They are typically natural and nutrient-rich, providing your body with essential vitamins, minerals, and antioxidants. By incorporating more whole foods into your diet, you can support a healthy immune system, reduce the risk of chronic diseases, and maintain a healthy weight. For example, try to eat more apples, carrots, leafy green vegetables, beans, lentils, and chickpeas.
Processed foods, on the other hand, are often loaded with chemicals, added sugars, unhealthy fats, and artificial ingredients that can be harmful to your body. These include packaged snacks, canned foods, frozen meals, and anything that has been changed from its natural state. Eating a diet high in processed foods can increase the risk of cardiovascular disease, heart disease, and even cancer.
To avoid unhealthy snacks that are high in fat, sugar, or salt, be mindful of the ingredients and nutrition labels. Many snacks marketed as "healthy" or low-fat are actually loaded with salt, sugar, or unhealthy fats. Instead of reaching for processed snacks, opt for whole food options like fruit, nuts, or homemade hummus with carrot sticks.
In addition to the physical health benefits, eating whole foods can also positively impact your mental health. Studies have shown that a diet rich in whole, unprocessed foods is associated with a lower risk of developing depression and other mental health disorders. Cooking and preparing meals with whole, unprocessed ingredients can also be a therapeutic and enjoyable activity, improving your overall mental well-being.

Eat at least five servings of fruits and vegetables a day
If you are 12 years old and considering going on a diet, it is important to focus on healthy habits and not drastically cut calories or nutrients. Eating at least five servings of fruits and vegetables a day is a great way to stay healthy and can help you maintain a healthy weight.
Fruits and vegetables are typically low in fat and calories, provided they are not fried or roasted in large amounts of oil. They are also a good source of vitamins and minerals, including folate, vitamin C, potassium, magnesium, and fiber. These nutrients are strongly linked to good health, especially heart and blood vessel health. Research has shown that eating five servings of fruits and vegetables per day is associated with a lower risk of many health conditions, including heart disease, stroke, and some types of cancer, compared to eating just two servings per day.
To get the most out of your five servings, aim for a variety of fruits and vegetables to ensure you get a good mix of nutrients. For example, green leafy vegetables like spinach, kale, and lettuce are particularly beneficial, as are fruits and vegetables rich in vitamin C and beta carotene, such as citrus fruits, berries, and carrots.
- Keep a variety of fruits and vegetables readily available. Wash, cut, and store them in your fridge so they are easy to grab when you're hungry.
- Include a side of vegetables or a side salad with your meals. If you're making a salad, add some grilled chicken or fish for extra protein.
- Choose fruits and vegetables that you enjoy eating. That way, you're more likely to stick to your goal of five servings per day.
- Get creative with your recipes. Try new recipes or experiment with different ways to cook your vegetables, such as steaming, roasting, or stir-frying.
- Opt for fruits and vegetables as snacks. For example, baby carrots, apple slices, or a handful of berries are nutritious and satisfying snack options.
Remember, it's important to listen to your body and maintain a balanced diet. While five servings of fruits and vegetables are recommended, it's okay to have days where you eat less or more. Focus on overall healthy eating patterns and making gradual, sustainable changes.

Drink low-fat milk and water instead of sugary drinks
If you are 12 and thinking about going on a diet, it is important to remember that diets that drastically cut calories or do not provide enough important nutrients can be harmful. Instead of dieting, it is recommended to focus on healthy habits, such as eating more fruits and vegetables, cutting back on treats, and exercising.
Drinking low-fat milk and water instead of sugary drinks is one way to develop healthier eating habits. Firstly, milk is a great source of calcium and vitamin D, which are vital for bone health. Calcium is needed to build and maintain strong bones, and vitamin D helps our bodies absorb calcium. Milk is also a good source of vitamin B12 and potassium. In addition, milk is a great vegetarian protein source, and the combination of carbohydrates, protein, and fat found in milk can help with weight loss by keeping you full. Research has also shown that including dairy in a calorie-restricted diet can result in greater weight loss and fat loss while reducing the loss of lean muscle.
Water is also an important part of a healthy diet, as it is the body's preferred way to hydrate and is naturally sugar-free. Drinking water instead of sugary drinks can help to reduce your sugar intake and add beneficial antioxidants to your diet. Sugary drinks, such as soda, juice, and sports drinks, are the number one source of added sugars in our diet, and it is easy to consume more sugar than you realize.
There are also other drink options that can provide variety and additional nutrients. For example, unsweetened coconut water is a natural source of vitamins and minerals, including potassium, magnesium, and sodium, and is also low in sugar. Green tea is another healthy option, as it is calorie-free and high in antioxidants. Finally, if you enjoy coffee, drinking it in moderation can be part of a healthy diet, and unsweetened coffee with a small amount of low-fat milk is a good choice.

Get at least one hour of physical activity every day
It is recommended that children and adolescents aged 6 to 17 get at least 60 minutes of moderate-to-vigorous physical activity every day. This can include aerobic activities such as walking, running, or anything that makes their heart beat faster. It is important to note that this 60 minutes of daily activity can be accumulated through several shorter sessions throughout the day, rather than needing to be completed in one continuous session.
- Incorporate physical activity into your daily routine: Try to find opportunities to move your body throughout the day. For example, you can walk or bike to school instead of taking the bus. Take the stairs instead of the elevator. Offer to help with chores around the house, such as gardening, raking leaves, or vacuuming. These activities can all contribute to your daily physical activity goal.
- Join a sports team or club: Consider signing up for a sport that interests you, such as soccer, basketball, swimming, or dance. This is a great way to stay active and make new friends at the same time. Look for local clubs or teams that you can join, and don't be afraid to try something new!
- Make it fun: Find physical activities that you enjoy and look forward to doing. This could be skating with friends, playing tag, jumping rope, or even just dancing in your room. The key is to find activities that you love, so you're more likely to stick with them.
- Be active with friends and family: Invite your friends or family members to join you in your physical activities. You can play outdoor games together, go on hikes, or even just take a brisk walk around your neighborhood. Having company can make being active more enjoyable and help you stay motivated.
- Create a schedule: Plan out your week and set aside time each day for physical activity. By scheduling your workouts or activities, you're more likely to commit to them. Treat your physical activity time as non-negotiable, just like any other important appointment or commitment.
- Try different activities: Variety is key to staying motivated. Each day, try a different activity that you enjoy. This could be a different sport, a fitness class, or even an active video game. By mixing up your routine, you'll not only stay engaged but also work on developing a variety of skills and strengths.
Remember, regular physical activity has numerous benefits for your health and well-being. It can improve your heart health, help you feel better about yourself, and contribute to your overall growth and development. So, find activities that you love, and make them a part of your daily routine!
