Weight Loss Success Statistics

Can people successfully lose weight and keep it off? It's a decades-long (and sometimes contentious) question. What's more, researchers still don't have a definitive answer. Here are some weight-loss facts that fuel the debate.

Long-Term Weight Loss Success Rate

Many experts define "successful weight loss" as a 10 percent reduction in body weight, maintained for at least a year. (According to the CDC, if you have overweight, losing 5 to 10 percent of your total body weight can improve your blood pressure, cholesterol and blood sugar levels.)

That said, an August 2023 study in ‌JAMA Network Open ‌followed individuals with overweight and obesity and found that the annual probability of 5 percent or greater weight loss in these people was low (1 in 10). But chances for weight loss increased in patients with a higher initial BMI. The study concluded that more public health efforts should be aimed toward encouraging clinically meaningful weight loss for anyone with overweight.


Weight Regain Statistics

People who initially lose weight on a diet or exercise program often gain the weight back over time, according to a January 2018 research review in Medical Clinics of North America. Here's a closer look at the numbers:

  • Within 2 years, people tend to regain more than half the weight they initially lost
  • Within 5 years, people tend to regain about 80% of the weight they initially lost

  • 78% of NWRC members eat breakfast every day

Here's a look at popular weight-loss strategies, diets, supplements, and more.


Some of the most common types of weight-loss strategies are dieting, exercising and/or eating healthy foods, according to the 2018 report from the CDC. Here's a breakdown of how people are trying to shed pounds:

Americans spend about $2.1 billion a year on diet and weight-loss pills (including tablets, capsules and softgels).

Drugs and Medications for Weight Loss

There are four drugs that have been approved by the FDA for weight loss, including Contrave, Saxenda, Xenical and Qsymia, according to the Mayo Clinic. Many of them work by decreasing a person's appetite or increasing a person's satiety levels.

Surgery for Weight Loss

Weight-loss surgery — also known as metabolic and bariatric surgery — is a procedure that can help many people lose weight, either by making the stomach smaller or altering the small intestine to limit the number of calories a person can absorb. Here are a few facts about weight-loss surgery, according to the National Institute of Diabetes and Digestive and Kidney Diseases:

  • People who have weight-loss surgery lose an average of 15 to 30% of their original weight
  • Weight-loss surgery can cost between $15,000 and $25,000, depending on the type of procedure you have and your insurance plan (Medicare and Medicaid may help cover the costs)
