How Are Injectable Weight Loss Medications Changing and Impacting Traditional Dieting?

Injectable weight loss medications

Injectable weight loss medications are proving far more efficacy than traditional dieting or exercise. Clinicals trials using Wegovy showed an average of 15% body weight loss. Comparing these numbers to traditional dieting showed the drug to provide five times more weight loss. Injectable weight loss drugs are able to prevent hunger and cravings making it easier for patients to make changes to their lifestyles. Telling a patient that is obese to make lifestyle changes is often ineffective. Injectable weight loss drugs help the brain change lifestyle habits that are necessary to make a diet work. These injectable medications show that the metabolism and hormones in the body plays a large role in weight loss. Traditional dieting does not alter hormones to curb a person’s appetite or cravings. Injectable weight loss drugs provide effective weight loss to prevent unwanted diseases associated with obesity.

How do patients lose weight?

The injectable weight loss medications are effective, so how do they work? There are 2 ways GLP-1 receptor agonists can help a patient lose weight. It causes the stomach to empty slower. This means patients will eat smaller amounts. GLP-1 receptor agonists also signal to the brain that the stomach has food. It is shown to decrease appetite and cravings.
