In a 68-week clinical trial of 1,961 adults, people taking semaglutide lost an average of 14.9% of their body weight, compared with just 2.4% for those on placebo [1]. More than 86% of the semaglutide group lost at least 5% of their weight [1]. Those numbers changed how doctors think about weight loss. They also explain why so many people who “did everything right” on a diet never saw lasting results.
Medical weight loss is a provider-led program that combines prescription medication, such as a GLP-1, with metabolic lab testing, a personalized nutrition plan and regular check-ins. It treats the hormonal and metabolic reasons your body holds on to weight. At Simone Medical in Matthews, NC, 12-week programs combine all of these with ongoing support.
You are far from alone if you have struggled. About 41.9% of U.S. adults have obesity, up from 30.5% two decades earlier [2]. That rise did not happen because millions of people suddenly lost their willpower. It happened because modern life works against the systems that control hunger, energy and fat storage.
Why Traditional Diets Stop Working
The hormones behind hunger and fat storage
Your weight is not only a math problem of calories in and calories out. Hormones such as insulin, cortisol, thyroid hormone, estrogen and testosterone decide how hungry you feel and where your body stores fat. When those signals are out of balance, eating less and moving more often stops working.
Ghrelin, often called the hunger hormone, is a good example. It rises when your stomach is empty and tells your brain it is time to eat. It also promotes the storage of body fat [3]. Even more frustrating, ghrelin levels increase after you lose weight by restricting calories, which may explain why dieting gets harder over time [3].
How stress and sleep sabotage your progress
Cortisol, your main stress hormone, releases sugar from your liver for quick energy. When stress becomes chronic, cortisol stays high. This can lead to weight gain, especially in your face and belly, and to high blood sugar that can turn into type 2 diabetes [4].
Sleep plays a role too. Poor sleep raises cortisol, creating a cycle that is hard to break [4]. Cleveland Clinic recommends seven to eight hours of sleep each night to help keep ghrelin and other hormones in a healthier range [3]. Learn more in Can Lack of Sleep Cause Hormonal Imbalance?
Why willpower isn’t the problem
Many of our patients arrive frustrated and blaming themselves. They have counted points, cut carbs and tried every new plan. The problem is rarely discipline. A body with insulin resistance, poor sleep or shifting hormones sends strong signals to eat more and move less, and willpower rarely outlasts biology.
Addressing those signals directly is what makes medical weight loss different. You stop fighting your body and start working with it.
Signs Your Weight Has a Metabolic Cause
Insulin resistance and prediabetes
More than 2 in 5 American adults have prediabetes [5]. Many don’t know it, because early insulin resistance often causes no symptoms at all [6]. Extra fat around your belly and organs raises your risk [6].
The encouraging part is how much a modest change can help. Losing just 5–7% of your body weight, about 10–14 pounds for a 200-pound person, can sharply lower your risk of type 2 diabetes [5]. In the CDC’s National Diabetes Prevention Program, that level of weight loss plus regular activity lowered diabetes risk by 58% [5].
Hormonal shifts with age
For many women, weight changes begin during perimenopause, when estrogen and progesterone start to fluctuate. For many men, a slow drop in testosterone leads to less muscle and more belly fat. If either sounds familiar, your plan may pair with women’s hormone therapy or men’s hormone therapy.
Common red flags
Your weight may have a hormonal or metabolic driver if you notice:
- Belly weight that won’t budge
- Strong cravings, especially for sugar and refined carbs
- Energy crashes in the afternoon
- Weight gain that began during a hormonal transition
- Poor sleep or high stress that lines up with weight changes
- Labs that come back “normal” even though you don’t feel normal

How GLP-1 Medications Support Weight Loss
What GLP-1 does in your body
GLP-1 is a hormone your gut releases after you eat. It triggers insulin release, blocks glucagon, slows how fast your stomach empties and increases how full you feel after a meal [7]. GLP-1 medications such as semaglutide mimic this hormone and bind to the same receptors [7].
The result is less hunger, fewer cravings and steadier blood sugar. Most patients find they feel satisfied with smaller portions without feeling deprived. For a deeper dive into the science, read How Does Semaglutide Work?
What the research shows
The STEP 1 trial followed adults with overweight or obesity for 68 weeks. Participants who took weekly semaglutide alongside lifestyle changes lost 14.9% of their body weight on average, while the placebo group lost 2.4% [1]. That is roughly six times more weight loss than lifestyle changes alone in the same study.
Results vary from person to person. Your dose, your consistency and your daily habits all shape your outcome, which is why medication works best inside a full program.
Side effects and safety
The most common side effects are loss of appetite, nausea, vomiting and diarrhea. They are most likely when you first start or when your dose goes up [7]. In STEP 1, 4.5% of people stopped semaglutide because of digestive side effects [1].
Rare but serious side effects include pancreatitis and kidney problems [7]. GLP-1 medications are not safe during pregnancy, and people with a history of medullary thyroid cancer should avoid them [7]. This is why a careful medical review before you start matters so much.
What a Medical Weight Loss Program Includes
Comprehensive metabolic testing
Every medical weight loss program at Simone Medical starts with comprehensive labs. Testing looks for hormonal imbalances, thyroid issues and metabolic barriers that make weight loss harder. Your results shape your plan, so you are not guessing.
A personalized nutrition and lifestyle plan
Your plan supports fat loss without extreme restriction. It focuses on protein, fiber and whole foods that keep your blood sugar steady. It also targets the habits that drive weight gain, including sleep and stress.
Movement is part of the plan as well. The CDC recommends 150 minutes of moderate activity each week plus two days of muscle-strengthening exercise [9]. Strength training is especially important on a GLP-1, because it helps you keep muscle while you lose fat. Adults also need at least seven hours of sleep each night [8]. Want to start now?

Ongoing monitoring and support
You are never left on your own. Your program includes:
- Weekly GLP-1 injections shipped to your home in 5–7 business days
- Video visits, or in-person visits at our Matthews office
- 24-hour messaging with your care team
- Regular check-ins and dose adjustments
GLP-1 microdosing
Simone Medical also offers GLP-1 microdosing. This approach uses lower, carefully adjusted doses. Some patients choose it to limit side effects. Others use it to maintain results after reaching a goal weight. Your provider monitors you closely and pairs every dose change with lifestyle recommendations.

What the program includes
Twelve-week programs include medication, labs, visits and messaging. Simone Medical does not bill insurance, but many patients use HSA or FSA funds. See all options on the Services page.
Your first steps

- Complete your intake and comprehensive labs.
- Review your results and personalized plan.
- Start treatment and check in regularly as you progress.
Conclusion
Diets fail because they ignore the hormones that control hunger, stress and fat storage. GLP-1 medications, paired with testing, nutrition, movement and steady support, address those drivers directly. The research shows this approach produces far greater weight loss than lifestyle changes alone, and even modest results can lower your risk of diabetes. If you are ready to stop guessing, book a consultation and find out whether medical weight loss is right for you.
