Metabolic health is the sum of how efficiently your body converts food into energy, stores and mobilizes fuel, regulates blood sugar, and maintains a healthy body composition. Hormones, your body’s chemical messengers like testosterone, estrogen, human growth hormone, thyroid hormone, insulin, and cortisol are instrumental to all of those processes.
When key hormones like these decline with age or become imbalanced, it can have a direct impact on metabolic efficiency. This can make it difficult to maintain lean muscle and burn fat. It can also have an impact on weight gain by affecting appetite and insulin sensitivity. This is why people with hormonal imbalances such as low testosterone or age-related growth hormone deficiency (AGHD) often notice an increase in stubborn abdominal fat and a plateau in weight loss despite disciplined lifestyle efforts.
Hormone Replacement Therapy (HRT), when medically indicated and responsibly monitored, helps restore hormonal balance so your metabolism can work as intended. For example, in men diagnosed with low testosterone (hypogonadism), evidence shows testosterone replacement therapy (TRT) improves body composition and can reverse insulin resistance. In women, menopause triggers a rapid shift in body fat distribution and energy expenditure; appropriately prescribed menopausal hormone therapy can mitigate central fat gain and support better metabolic parameters.
In both genders growth hormone replacement in adults diagnosed with AGHD has been shown to improve the ability to build muscle and burn fat. HGH Therapy also reduces the risk of metabolic conditions like type 2 diabetes.
At Nexel Medical, our approach integrates evidence-based HRT with nutrition, strength training, sleep optimization, and targeted weight-management tools. This comprehensive strategy is how we help patients improve energy, reshape body composition, and regain metabolic control safely and predictably.
Hormones act like the operating system for your metabolism:
If the levels of any of these hormones are off, metabolism suffers and weight gain, loss of muscle and lack of energy are the results.
Weight management is easiest when you protect or rebuild lean body mass. Muscle is metabolically active, improves insulin sensitivity, and raises your metabolism even at rest. Low testosterone and AGHD are both associated with reduced lean mass and increased visceral fat. Medically-supervised testosterone therapy and/or HGH Therapy paired with progressive resistance training and protein-forward nutrition helps reverse that trend.
Clinically, we see the best results when HRT is used as a metabolic enabler rather than a stand-alone “fix.” That means we target dosing to your individual needs, monitor hormone levels with lab testing, and coordinate with a structured plan for nutrition, training, sleep, and stress management. The outcome: fewer plateaus, better adherence, and more durable fat loss.
Several hormones strongly influence how responsive your cells are to insulin:
Metabolic syndrome is defined as a cluster of conditions including abdominal obesity, hypertension, insulin resistance and impaired glucose regulation. The risk of developing metabolic syndrome rises sharply with age due to age-related hormone loss. Evidence suggests that in men with low testosterone, testosterone therapy can improve several components of metabolic syndrome such as waist circumference, insulin resistance, and cholesterol issues.
In postmenopausal women, estrogen depletion leading to increased belly fat and insulin resistance also increases the risk of metabolic syndrome. Studies have indicated that HRT for women has been associated with a reduction in abdominal fat and also suggest a lower incidence of diabetes.
It is important to point out that HRT is usually not prescribed strictly for weight loss. While it can help people struggling with weight, testosterone or HGH are not considered “weight loss drugs.” Rather, their value is restorative. HRT is designed to normalizes the hormonal conditions that allow the body to respond to diet and exercise better. Patients often notice improved energy and recovery, making consistent training easier, better sleep, which stabilizes hunger hormones, and a shift toward more lean mass and less visceral fat.
Over time, these changes support healthy fat loss and metabolic health. At Nexel Medical, HRT is integrated with nutrition coaching and resistance training to translate those physiological changes into measurable weight-loss milestones.
In men with clinically diagnosed hypogonadism, properly dosed testosterone therapy is associated with reduced fat mass, lower waist circumference, and improved insulin sensitivity, particularly when combined with lifestyle intervention. Testosterone therapy enables fat loss by rebuilding lean mass, enhancing mitochondrial activity, and improving insulin action. When combined with increased physical activity, particularly strength or resistance training, and dietary changes one of the many benefits of testosterone therapy can be significant weight loss.
The two-year T4DM randomized, placebo-controlled trial in older, high-risk men found that testosterone treatment reduced progression to type 2 diabetes by ~40% on top of a structured lifestyle program, while improving body composition. Importantly, therapy required ongoing monitoring (e.g., hematocrit) and individualized risk-benefit assessment.
For appropriately selected men with low testosterone and metabolic risk, these data suggest testosterone can reduce diabetes risk when used with lifestyle modification and medical oversight.
Yes. Adults with HGH deficiency typically present with increased visceral fat, reduced lean mass, dyslipidemia, lower exercise capacity, and impaired quality of life, all of which worsen metabolic risk. Growth hormone replacement therapy in adults who have been tested and diagnosed with GHD improves body composition, decreases insulin resistance, lowers the risk of diabetes and other metabolic conditions associated with obesity.
For adults with confirmed HGH deficiency, HGH replacement therapy often reduces visceral adiposity (belly fat) and increases lean mass, which can visually translate to a smaller waist and better muscle definition.
HGH therapy promotes fat burning and weight loss primarily by stimulating lipolysis—the breakdown of stored fat—and by building lean muscle mass. This shifts the body’s metabolism to use fat for energy instead of glucose. HGH acts on fat cells (adipocytes) to activate an enzyme called hormone-sensitive lipase (HSL). HSL breaks down triglycerides, the stored form of fat, into free fatty acids and glycerol, which the body then uses for fuel. HGH also blocks an enzyme called lipoprotein lipase (LPL) that moves fatty acids from the bloodstream into fat cells. This two-part action—releasing stored fat and preventing new fat accumulation—is particularly effective at reducing visceral fat, the harmful fat that surrounds abdominal organs.
HGH also boosts metabolism. The combination of increased fat burning and muscle development leads to a higher overall metabolic rate, meaning the body burns more calories even at rest.
HGH is intimately linked with glucose metabolism. HGH therapy’s impact on glucose metabolism is complex: it can decrease your risk of diabetes indirectly by improving body composition. As mentioned above, HGH plays a major role in lipolysis, the breakdown of stored fat. In fact, HGH accelerates this process; HGH therapy can result in significant fat loss and helps individuals achieve their weight loss goals. Obesity is one of the main risk factors in the development of type 2 diabetes.
A study entitled Obesity, growth hormone, and weight loss concluded that growth hormone could indeed reduce abdominal fat.
Another found that HGH specifically reduced obesity in post-menopausal women. And yet another on HGH and weight loss in children confirmed that “HGH had [fat burning] properties that resulted in reduction and redistribution of body fat.”
Weight gain around midlife is common, but menopause itself mainly changes where fat is stored. Any woman approaching or going through menopaus will tell you how it all “goes to her belly” rather than dramatically increasing total body weight. Robust evidence shows fat mass rises and lean mass declines across the menopausal transition, which increases cardiometabolic risk even if the scale hardly moves.
However, multiple trials and position statements indicate that properly prescribe HRT for women can blunt central fat accumulation and help preserve lean mass in perimenopausal and menopausal women.
While HRT for women is prescribed primarily for menopause symptom relief such as hot flashes, mood swings and night sweats, its metabolic benefits cannot be overlooked. Studies have found that estrogen replacement therapy can lead to a reduction in belly fat, favorable shifts in body composition, and lower incidence of new-onset diabetes.
Testosterone replacement and HGH therapy in woman has similar weight management benefits as they do for males.
At Nexel Medical, we coordinate HRT with structured medical weight-loss tools to create a cohesive plan:

We’ll assess your hormones, body composition, and cardiometabolic risk, then design a personalized HRT and weight-management plan to help you lose fat, protect muscle, and regain energy safely and sustainably.
Will hormone therapy alone make me lose weight?
No. HRT isn’t a weight-loss drug. It helps correct the hormonal environment, so your body responds to nutrition and training. Most patients see the best results when HRT is combined with resistance training, protein-forward nutrition, and quality sleep.
How long until I notice body-composition changes on HRT?
Many patients notice improved energy and sleep within weeks, with measurable changes in waist circumference and strength by 8–12 weeks—especially when training and nutrition are consistent. Body-fat reductions typically accumulate over several months.
What labs are monitored while on HRT for metabolic goals?
Typically: complete blood count (hematocrit), lipid panel, liver enzymes, fasting glucose and A1c (or CGM), thyroid panel, and—in GH therapy—IGF-1. We also track body composition, blood pressure, and waist circumference.
Can I combine HRT with GLP-1 medications (e.g., semaglutide)?
For selected patients, yes—under physician supervision. We coordinate therapy timing/dose and monitor for hypotension, dehydration, gallbladder issues, and nutritional adequacy while emphasizing resistance training to protect lean mass.
What if I have prediabetes or metabolic syndrome?
We’ll tailor a plan that may include HRT (if indicated), nutrition periodization, progressive resistance training, and possibly anti-obesity pharmacotherapy. Our goal is to reverse risk markers safely and sustainably.
