Obesity is a condition characterized by the presence of excess body fat. A person who is obese has a body mass index (BMI) of over 30.

The United States currently ranks as the most obese high-income country in the world.1 19 out of 50 U.S. states have obesity rates over 35 percent as of 2022.2

Obesity puts you at risk for multiple chronic conditionsÑsuch as type 2 diabetes and heart disease. But it can be treated and prevented with weight management.

One way to reduce your calorie intake and lose weight is to eat more fruits and vegetables.3 Regular exercise can enhance the effects of a calorie-restricted diet.4

Why Obesity Is A Problem

People who are obeseÑwhen compared to people with normal weightÑhave a higher risk for many serious diseases and health conditions.

Studies show obesity increases your risk for the following:5,6

  • Breathing problems (e.g., sleep apnea)
  • Coronary heart disease
  • Gallbladder disease
  • High blood pressure (hypertension)
  • High LDL cholesterol
  • Osteoarthritis
  • Some types of cancer
  • Stroke
  • Type 2 diabetes mellitus
  • Death

Obesity also reduces your quality of life. YouÕre more likely to experience mental health problems, body pain, and difficulty functioning in your daily life.7,8,9

Why Eating Fruits & Vegetables Matters

Decreasing your calorie intake is an important step when youÕre trying to lose weight. However, this doesnÕt mean you have to eat less.

Eating more fruits and vegetables allow you to decrease your calorie intake without depriving yourself. This is because they are rich in fiber and water.3

Fruits and vegetables can make you feel full without the calories. They can also provide you with other essential nutrients for maintaining good health.

The recommended dietary intake for American adults is 1.5 to 2.5 cups of fruit per day and 2.5 to 3.5 cups of vegetables per day.10,11

How Regular Exercise Helps

The Physical Activity Guidelines for Americans recommends 150 to 300 minutes of moderate activity per week and at least two days of muscle-strengthening activities.12

While exercising contributes to good health, exercise alone has very little effect on a personÕs weight.13

Studies show you have to exercise for more than the recommended 150 minutes weekly to lose and maintain a healthy weight.13 
If you want to lose weight more efficiently, most experts recommend combining exercise with a calorie-restricted diet and a healthy lifestyle.4
