GLP-1s + HRT: Metabolic Health for Men and Women Over 40 in Chattanooga

If you’re over 40 and feeling like your body has quietly changed the rules, you’re not imagining it. The weight that used to come off with a little effort now hangs on. Energy dips in the afternoon. Sleep feels less restorative. For many adults in the Chattanooga and Signal Mountain area, two things are happening at once — and treating only one of them leaves results on the table.

At Summit Metabolic Health, we look at the whole picture. That means addressing both the hormonal shifts that come with age and the metabolic slowdown that drives stubborn weight gain.

After 40, hormones decline. In men, testosterone gradually falls — see our physician’s guide to TRT for men in Chattanooga for what that looks like in practice. In women, perimenopause and menopause bring shifting estrogen and progesterone, which is its own driver of menopause-related weight gain. At the same time, metabolic rate tends to slow and appetite regulation changes, so weight creeps up even when habits haven’t.

These are different problems, and they respond to different tools:

– Hormone replacement therapy (HRT) addresses the hormonal side — supporting how you feel day to day when labs confirm a genuine deficiency. – GLP-1 medications (semaglutide, tirzepatide) address appetite and weight by reducing hunger and slowing gastric emptying.

Used together, under physician supervision, they can support energy, body composition, and overall metabolic health more completely than either alone — we go deeper on exactly why neither one alone gets the job done in a separate breakdown.

The weight-loss data on GLP-1 medications is strong. In the STEP 1 trial (NEJM, 2021), semaglutide produced a mean body-weight reduction of about 14.9% at 68 weeks. Tirzepatide, in SURMOUNT-1 (NEJM, 2022), showed about 20.9% at the 15 mg dose over 72 weeks. A head-to-head trial, SURMOUNT-5 (NEJM, 2025), found tirzepatide (~20.2%) outperformed semaglutide (~13.7%). Individual results vary.

These are appetite and metabolism tools — not hormone tools. That distinction is why a combined, individualized plan matters.

HRT is not for everyone, and it isn’t an anti-aging shortcut. It requires lab work, appropriate screening, and ongoing monitoring. The right candidate, the right dose, and the right follow-up are all individualized decisions — and the benefits and risks differ from person to person. Specific hormone-outcome figures should be discussed with your physician based on your own labs and history [VERIFY].

This is exactly where physician oversight earns its keep. At Summit, Dr. Paul Miranda, MD, MBA — board-certified and an ER physician by training — personally reviews every patient’s chart. Not a software questionnaire. Not a nurse queue. A physician who reads your labs, weighs your history, and builds a plan around you.

We serve patients across Tennessee, Florida, Washington, Ohio, and Georgia — in person at our Chattanooga office and by telehealth. For neighbors here on Signal Mountain and across the Scenic City, that means real, physician-directed care close to home.

Two things set the program apart:

1. Custom-dosed therapy. We use custom-dosed compounded GLP-1 medication and tailor HRT to your labs, rather than a one-size-fits-all script. 2. A plan that gets cheaper as you get healthier. Our program is designed with a descending price and a physician-directed maintenance and exit strategy — so the goal is durable health, not endless dependence.

GLP-1 side effects are predominantly gastrointestinal, concentrated during dose escalation (typically over about 16–20 weeks), and mostly mild-to-moderate and transient. These medications carry a boxed warning regarding thyroid C-cell tumors, which is part of every candidacy conversation.

It’s also worth knowing that stopping the medication tends to lead to substantial weight regain (STEP 4; SURMOUNT-4), while a lower maintenance dose holds results far better than stopping outright (SURMOUNT-MAINTAIN, Lancet 2026). And because significant weight loss includes some lean mass, we emphasize adequate protein and resistance training to protect muscle.

If you’re over 40 and tired of treating one symptom at a time, let’s talk about whether a combined, physician-supervised approach makes sense for you.
