There are many known causes of weight gain but the fact is we gain weight due to lack of self control.

Many factors contribute to obesity, one of the chief reasons being junk food and lack of exercise.

Be Physically Active
The most common way to prevent obesity is to live an active lifestyle.

Simple activities, such as climbing the stairs instead of using lifts, walking to the store, morning and evening walk in the park and swimming, can bring about tremendous changes in your lifestyle.

Such activities will not only help you burn excess fat, but also help you stay active. Start doing light to moderate exercises for thirty minutes, five times a week. Switch over to the tough exercises, once you have gained stamina and strength.

You may also join a health club or gym. A local health club membership can be a wonderful way to stay active and socialize with other like-minded individuals

Eat healthy and Stay Away From a Junk Food
The FDA recommends that the average person consume 2,000 calories per day in foods such as dairy, meats, breads, fruits, vegetables and legumes. Tailoring your diet to meet these FDA standards is the most effective way to prevent obesity. One of the prerequisites of staying healthy is avoiding junk foods. The smart way to stay away from junk food is not to buy them at all! Keep junk food out of your house as well. If you really like stuff like pizza and burgers, indulge in them not more than once or twice a month.

Watch your weight and Keep A Check On it
Monitor your weight regularly. You should weigh yourself once a week to monitor your health. This will help you figure out how much extra flab you have lost by doing simple activities or workout. If you notice that you are starting to gain some weight, you should take appropriate measures to stop weight gain and lose the excessive pounds at an early stage.

Drink Plenty Of Water
Water is good for you and your well being! Drinking lots of water will help your body detoxify all the impurities present in the system. The FDA recommends drinking eight to 10 glasses of water per day. Having a glass of warm water in the morning, with half a lemon squeezed in it, is also a good idea. Remember, water cleanses and detoxifies all the impurities in your system, and rejuvenates your skin as well.

Get a physical at least once a year
Doctors advise that adults receive a medical physical on a yearly basis to prevent any health complications. Doing so, you can catch any early complications, and treat yourself accordingly.

Eat Slowly & Only When You Are Hungry
Studies have shown that those who are naturally thin only eat when they are hungry.
Do not cut any of the three meals per day. Rather, divide them into small meals, stretched over a gap of 2-3 hours. At the same time, cut off high-calorie snacks in between the meals. Eat small portions of food and do not gulp them down. Do not stuff yourself with food when you are not hungry. Only eating when your body signals you to eat can be a great way to prevent obesity. Eat slowly because the stomach takes about 15 minutes to feel ‘full’.

Diet
Build and eat well balanced diet – The more fruits, vegetables and whole grains in diet, the better. An obese adult should have at least five servings of low-sugar fruits and vegetables on a day. Include in your diet one cup of raw or one and half cup of cooked vegetables. One food serving includes — One piece of fresh fruit and one and half cup of canned fruit. Try to avoid fruits and vegetables that are high in calories, like mango.
