Why is weight control important?

If you are struggling with your weight, you are not alone. In the United States, more than 70 percent of adults are overweight or have obesity. Having this extra weight raises your risk for many health conditions, such as type 2 diabetes, heart disease, kidney disease, and certain cancers.

Reaching and staying at a healthy weight can be challenging. But having a healthy lifestyle, including healthy eating patterns and regular physical activity, can help you lose weight. It can also lower your chance of developing weight-related health conditions.

What factors affect weight and health?

You gain weight when you take in more calories (through food and drinks) than you use up from physical activity and daily living. But there are many different factors that can affect weight gain, such as:

How can I get to and stay at a healthy weight?

Getting to and staying at a healthy weight involves finding a balance of food and activity. To lose weight, you need to take in fewer calories than you use up. Some ways to do this are:

You may decide to do these lifestyle changes on your own, or you may decide to try a weight-loss diet or program. Before you start, it's important to check with your health care provider first. Your provider can tell you what a healthy weight is for you, help you set goals, and give you tips on how to lose weight.

What are weight management medicines?

If making lifestyle changes or doing a weight-loss program are not enough to help you lose weight, your provider may prescribe medicines. These medicines are meant to help people who have weight-related health conditions and should be used along with healthy eating and physical activity. The prescription medicines to treat overweight and obesity work in different ways. Some may help you feel less hungry or full sooner. Others may make it harder for your body to absorb fat from the foods you eat.

Another treatment is weight loss surgery. Your provider may recommend the surgery if you have severe obesity or serious obesity-related health problems and you have not been able to lose enough weight.

How can I maintain my weight loss?

Maintaining weight loss can be challenging, and it's normal to slip back into old habits sometimes. The key is to keep a healthy balance of food and activity that works for you. Checking your weight regularly can help you notice small changes early and stay on track. And if you have a setback, don't be discouraged, simply refocus on your healthy habits and keep going.
