How can I maintain a healthy body weight?

By eating a balanced diet and regular exercise. You should consider consulting a nutritionist to know the best diet for you.

Eat healthy. Stay away from unhealthy food. Plus exercise. Try to make a schedule for exercise. More than anything, stay motivated. Just believe you can do it. Don't let anyone bring you down. My love and best wishes.

By eating a healthy, balanced diet. There are many videos on the internet (e.g. on youtube) showing you how to prepare nutritout means. You can also exercise 3 times a week, but make sure you talk to your doctor about what exercise plan suits you best.

I find my fitness pal really helpful. It calculates how many calories you can eat a day to maintain your weight. It takes some time at first to log all the food your eating but eventually you will have a pretty good idea of how much you can eat in a day. Also accounts for how many calories you're burning through exercise.

Eat smaller portions but get full by healthy, food snacks that does not have many calories such as vegetables. Slice your favorite vegetables such as sweet peppers or radishes and put a little lemon and spices and enjoy them slowly with a glass of water with a touch of lemon to make it interesting. Have friends that have the same healthy eating and exercise goals. Find exercises that you enjoy.

By eating well, and exercising regularly. Eat a balanced diet, enough calorically, but not too much. A good website I use is chronometer, it tracks your calories as well as your nutrients. Try cooking at home, and look up recipes online. It should be fun. Make healthy alternatives to your favorite meals, for example, make lasagna with eggplant instead of meat. Also, try steaming veggies, and putting your favorite sauces on them. Eat multiple smaller meals, instead of 3 large ones. This will make you feel less hungry in between. As Ash said, stay away from the unhealthy food, but don't be afraid to eat something a bit unhealthy once in a while. Moderation is key :) As for exercising, to whatever you enjoy. Dancing, yoga, running, karate, the list is endless. Just remember to have some off days so you can rest, and not strain yourself. Ask your doctor what they think will work best for you. Good luck

There are just a few things in place to have: How much you're eating? What you're eating? When you're eating? How much do you move? How do you manage stress? That's it. Find the right answers. Follow them and enjoy yourself. You might be chubby by nature - learn to embrace yourself, and love yourself. But only after you figured those questions above. Yes. Because it's also about your health, not just your looks. Big Love!

The best you can do is work towards following a physical health routine that fits what you have been taught (by nutritionists, teachers, or through guidelines). Diet is something that shifts with us as we go through changes and often depends on the habits we set, among other factors. The same goes for being active. The best is to work on progressive and well-meant changes that are not too much to take on. Just do your best, most of the time, and you will be okay! And seek medical advice if you're concerned about factors that may be outside of your control & mental health advice if you require support.
