Low testosterone, extra weight, less muscle. Treat them as one problem, not three.
A plain-language guide for men roughly 40 to 65 who feel their energy, strength and drive slipping while the scale goes the wrong way: how testosterone and a GLP-1 each work, why Dr. Miranda treats them together, and what we test first.

Why this page exists
These problems feed each other
Excess body fat is associated with lower testosterone, and low testosterone is associated with less muscle, more fat, lower drive and lower energy. A man can end up in that loop with one clinician for the weight, another for hormones, and nobody looking at both.
Testosterone falls
Levels drift down with age, and carrying extra weight tends to push them lower. Symptoms such as low drive, low energy and loss of strength are common, but they are not specific, so the number has to be measured.
Muscle is at stake
When weight comes off on a GLP-1, some of what is lost can be muscle, not only fat. Muscle is what keeps you strong, mobile and metabolically healthy as you age.
One physician, one plan
Dr. Paul Miranda reviews your labs, your GLP-1 and your testosterone question together, so the two treatments are judged as one plan and not as two separate prescriptions.
What each treatment does
Two treatments, two different jobs
- Testosterone therapy is for men who have both symptoms and a confirmed low testosterone level. In trials of men with low levels, treatment increased lean body mass and improved sexual desire and function. Effects on mood and energy were smaller and less consistent from man to man. (Endocrine Society guideline, 2018; TRAVERSE trial, 2023.)
- A GLP-1 medication is a weight and metabolic medication. Its job is to bring body weight and blood sugar down. It is not a testosterone treatment.
Why Dr. Miranda treats them together
Dr. Miranda’s view is that for a man with both problems, treating both together works better than treating either one alone: the GLP-1 takes the weight and metabolic strain off, testosterone supports muscle, drive and energy, and the strength and protein plan keeps what you build. Here is what we work toward.
Keep your muscle
Lose fat while holding on to lean mass, with testosterone, protein and strength training behind it.
Energy and mood
Feel like yourself again: steadier energy through the day, a better outlook, better sleep.
Drive and sex life
Bring back interest and function, which low testosterone and extra weight both take from men.
Weight that comes off
A GLP-1 for steady, physician-paced weight loss, with your labs watched the whole way.
This is Dr. Miranda’s clinical approach. Studies that compare testosterone plus a GLP-1 against either one alone are still early, so results vary and are not promised. Testosterone is not right for every man: it lowers sperm production, can raise red blood cell count, and needs prostate monitoring. Dr. Miranda decides after your labs and history.
Test first
The labs we check, and how often
We do not guess at testosterone. Dr. Miranda orders your labs and reads every result. You get your blood drawn at a Quest, LabCorp or local lab near you, and results come back to your Healthie patient portal, where he reviews them and messages you. The labs in this schedule are included in your Summit Men membership. This is Summit’s standard schedule, and Dr. Miranda adjusts it to your history and your results.
At the start
Metabolic baseline
Comprehensive metabolic panel (kidney, liver, electrolytes), HbA1c, a lipid panel (fasting preferred), and fasting insulin when we recommend it.
Hormones
Total and free testosterone. Drawn in the morning, when levels are highest. We test first, and Dr. Miranda reads the result alongside how you feel. Estradiol, plus DHEA-S and a morning cortisol when your picture calls for them.
Safety labs
A complete blood count, including hematocrit, because testosterone can raise red blood cell count, and a thyroid test (TSH). A PSA for men over 40.
How often we repeat them
- At month 3: repeat the metabolic panel, HbA1c and lipids.
- At month 6: repeat the metabolic panel and HbA1c, as your care calls for.
- Once a year: repeat the full panel.
- If you start testosterone: repeat the hormone panel 6 to 12 weeks after you start, then about every 6 months.
If you have had labs recently through your own physician, send them to us. Dr. Miranda decides whether they are enough or whether something needs repeating.
The rest of a complete plan
What else we look at, so nothing is missed
Testosterone is rarely the whole story. These are the questions a good men’s health physician asks, and the options Dr. Miranda can discuss with you. Each is prescribed only after an evaluation, and most men will not need all of them.
Estrogen
Some testosterone converts to estradiol in the body. We check estradiol with your labs. If it runs high and you have symptoms such as breast tenderness or swelling, we adjust the testosterone dose first. An aromatase inhibitor such as anastrozole is an off-label option, used sparingly.
Fertility and testicle size
Testosterone therapy lowers sperm production and can shrink the testicles. If you want children now or later, tell us before you start. Clomiphene and hCG are options that keep your own production going, and Dr. Miranda will go through which fits your goals.
Hair
Testosterone can speed up thinning in men who are genetically prone to it. If your hair matters to you, raise it at the start. Finasteride is FDA-approved for male pattern hair loss, and dutasteride is used off-label for it. Both have side effects worth a conversation.
Sexual function
For many men, treating low testosterone and weight is enough. If erections are still a problem, tadalafil or sildenafil, which work through the nitric oxide pathway, are FDA-approved options and can be added. They are not for men who take nitrate medicines.
Prostate and blood count
PSA and hematocrit are tracked on the schedule above, so a change is caught early.
One list of everything
Dr. Miranda keeps your GLP-1, testosterone and any add-ons on one medication list, so nothing is added without checking how it fits the rest.
Clomiphene, hCG, anastrozole and dutasteride are used off-label in men, meaning for a purpose the FDA has not approved them for. Medication decisions are individual and made with your physician.
Muscle
Protect what you are not trying to lose
A 2025 joint advisory from the American College of Lifestyle Medicine, the American Society for Nutrition, the Obesity Medicine Association and The Obesity Society lists muscle loss among the challenges of GLP-1 therapy and calls for nutrition and lifestyle support alongside the medication. Two habits carry most of the weight.
Protein, every day
Summit’s working target is roughly 1.2 to 1.5 grams of protein per kilogram of body weight per day, spread across meals. This is Summit’s own working target, not a guideline, and it is adjusted for your health (for example, kidney disease). Ask your clinician for your number.
Resistance training
Federal guidelines say adults should do muscle-strengthening activity of moderate or greater intensity, involving all major muscle groups, on 2 or more days a week. Start light, learn the movements, and build slowly.
Sleep and alcohol
Poor sleep and heavy drinking both push testosterone and recovery the wrong way. Untreated sleep apnea is common in men with excess weight, and it is worth asking about.
Muscle is “preserved,” not guaranteed. No habit on this page promises a result, and individual results vary.
Lift with Fit Life Training.
Strength training is the part of this plan no medication can do for you. Dr. Miranda sends men who want to keep muscle while the weight comes off to Fit Life. It is a personal training team in the Chattanooga area.
What to track
A simple self-tracking checklist
Keep this in your own notes or on paper. This page does not collect, store or send anything.
Every week
- Your medications, doses and the days you took them, and any dose change
- Protein: about how many days you hit your target
- Strength sessions completed
- Side effects: nausea, constipation, reflux, fatigue, dizziness, and how long they lasted
- Energy, mood, drive and sleep, in one line each
Every month
- Weight, waist and one strength marker (for example, how many push-ups or chair stands you can do)
- Morning blood pressure, if you have a home cuff
- Any change to supplements, other medications or alcohol
Whenever your care changes
- Which clinicians know about your GLP-1, and which know about your testosterone
- Date of your last labs, including PSA and hematocrit
Get urgent care for chest pain, shortness of breath, swelling or pain in one leg, sudden vision or speech changes, or severe belly pain that does not go away. Tell your clinician promptly about trouble passing urine, a painful or swollen breast, or an erection that will not go away.
Questions to bring to a provider
Ask these at your next visit
- Has my testosterone, total and free, been measured in the morning, and what do the results mean for me?
- Is testosterone appropriate for me, given my history, my prostate and whether I want children?
- How often will you check my red blood cell count, PSA and testosterone while I am on treatment?
- What protein target and strength plan fit me, and how will we check that I am keeping muscle?
- How will my GLP-1 dose be paced, what is the plan if side effects get in the way, and what is the plan if I want to stop?
- Do I need a sleep apnea test?
- Who is the one clinician coordinating my GLP-1, my testosterone and my labs, and how do I reach them?
Who coordinates it
Summit Men: one physician, one plan
Summit Men is Summit’s monthly membership for men in midlife: testosterone when your labs and symptoms qualify, GLP-1 management, labs, and a structured plan for protein and strength, with Dr. Miranda as your physician at every visit. Medication is prescribed only after a physician evaluation determines it is appropriate. Summit is telehealth only and licensed in the states listed in the footer. Current pricing is on the pricing page.
Testosterone is a controlled substance, so telehealth eligibility depends on your state and federal rules. Dr. Miranda confirms this with you first.
