What is medical weight loss? 

Medical weight loss refers to weight loss plans designed and supervised by experienced medical care professionals. This type of closely-monitored weight loss plan is ideal for anyone who wants to drop extra pounds or for people who experience detrimental health effects due to extra weight. 

What happens in a medical weight loss program? 

For many people, particularly those with chronic conditions, such as Type 2 diabetes, weight loss isn’t easy. Factors like insulin resistance can derail your best weight loss efforts. 

At Prosperity Internal Medicine, individual factors are always considered and accounted for as your providers design a personalized weight loss program. Some of the central aspects of most medical weight loss programs include: 


Prosperity Internal Medicine uses a scientifically-based, nutritional plan called Ideal Protein®. This ketogenic weight loss protocol provides plenty of lean protein while avoiding added sugar and other unnecessary additives. 

There are a wide range of Ideal Protein products, including pre-packaged breakfast foods, snacks, entrees, beverages and other ready-to-eat items to make your weight loss program easy to follow. 

The principle of the Ideal Protein program is replacing carbohydrate-heavy foods with tasty high-protein substitutes. This helps you stay full and can also increase your energy. 


Semaglutide is an injectable medicine that treats both Type 2 diabetes and obesity. Wegovy®, the FDA-approved semaglutide formula for medical weight loss, works by mimicking glucagon-like peptide-1 (GLP-1), a hormone that helps regulate your appetite. Ozempic® is the semaglutide approved for Type 2 diabetes. 

Injections, taken once a week, can reduce your appetite and lower your overall food consumption. You administer injections at home but still check in at Prosperity Internal Medicine regularly for support. 

Alongside Ideal Protein and semaglutide, many patients opt for natural weight loss boosters, such as vitamin B-12 shots and intravenous (IV) therapy.  

How long does medical weight loss take?

The length of your medical weight loss program depends on your weight goals and health needs. Prosperity Internal Medicine helps you make true long-lasting changes so maintaining your weight becomes simpler and easier than it’s ever been before.

Good nutrition and the right medication can make your medical weight loss program a big success. You can feel satisfied, motivated, and energized with the individualized weight loss programs at Prosperity Internal Medicine, so call the office or book an appointment online today.
