"My old skinny jeans fit me for the first time in 13 years.. done 1000 diets and never felt as strong or proud of my weight loss as I do with this"

Karen W., 54Verified Buyer

"I was scared to stop bcos I kept hearing the weight comes back. Watching my strength and muscle hold is why I'm not scared anymore."

Carol M., 61Verified Buyer

"I took the summary page in before we talked about my dose. My doc read the whole thing and asked me where I got it. First time I've had that."

It shows which way your muscle and fat are moving over time.

Why muscle matters on a GLP-1.

Researchers found that a meaningful share of the weight lost on these medications can be lean mass.

1 in 4

pounds lost on a GLP-1 isn’t fat.1

Reviewers have compared the lean mass lost on a 16-month course of GLP-1 treatment to roughly

20 years

of natural aging.2

Nobody’s watching it.

51%

of prescribing physicians in a 2025 Sermo poll said the risk of muscle loss on these medications “warrants better follow-up”.3

Yet, almost nobody is set up to monitor it. A check-in was built to manage your dose and side effects, not to measure your muscle.

Many people on a GLP-1 get little exercise or nutrition guidance for keeping their strength and muscle.4

Orvi Systems are built to protect muscle while the weight comes off, and support muscle growth when your body’s ready.

More muscle means more from life.

  • The more muscle you have, the easier you’ll find everyday tasks.
  • Climbing the stairs. Carrying the groceries. Playing with the grandkids.
  • It all gets easier.

Without muscle, lighter can also mean weaker.

Hit her protein on her worst days

"I can barely eat anything the day after a shot. each chapter works with the good days and the hardest ones, so I hit my protein most days now."

Phase 1

Orvi Protect System: for while the weight is coming off

  • 01 Fuel: Your protein target, and a plan for the days you can barely eat
  • 02 Protect: 3 simple strength sessions a week at home, no gym
  • 03 Measure: 3 progress signals and a review every 4 weeks
  • Built around your energy and appetite, even on the days after a shot.
  • Green, Yellow and Red days replace the calendar.
  • A progression rule tells you exactly when to up the intensity.
  • A baseline, 3 Four-Week Reviews, and a 1-page Clinician Summary.

The check-in: when to switch

At the end of the Protect System, the readiness check tells you whether to start the Grow System: your loss has slowed or settled, you’re eating enough protein most days, and your symptoms are manageable.

If you’re ready, you start the Grow System. If not, you keep your protein target and check again in 4 to 8 weeks. Holding is a good answer, not a failed one.

Phase 2

Orvi Grow System: for once the weight has settled

  • 01 Power: Your protein floor, your build target, and your Power Window
  • 02 Grow: 4 beginner-friendly gym sessions a week
  • 03 Measure: 3 progress signals and a review every 4 weeks
  • 04 Stepping down: For dose reductions, and what to do when the appetite returns
  • Written for all levels, tailored to shot-week cycles and energy.
  • A focus on building strength, not just maintaining it.
  • Guidance on maintenance, stepping down, and stopping. It never sets or alters a dose.

The Measure chapters in both phases are written for an 8-electrode scale. The Orvi Body Scan is the recommended instrument, but it’s not mandatory.

Ships free in 7 to 14 days.

"I joined a gym at 58, which I never thought I would say."
Yvonne T., 58 Verified Buyer

Nobody has a plan for when the weight settles.

  • Researchers found about 60% of the weight lost comes back within a year of stopping.5

  • This system is how you gain muscle, not fat.
The first plan that told her to eat more
Denise R., 50 Verified Buyer

"After a year of being told to eat less, a plan telling me to eat MORE felt wrong. Took me two weeks to trust it. But now I do, and it's all working great."

Built on the research.

Every recommendation is labeled by the strength of the evidence behind it, with all sources referenced at the back.

  • Direct GLP-1 evidence

    Studied directly in people taking these medications

  • Clinical consensus

    Recommended by a multi-society advisory for people on these medications, not yet confirmed by direct trials

  • Broader evidence

    From wider nutrition, exercise or measurement research

  • Practical strategy

    Sensible and field-tested, not a clinical claim

The files don’t set, alter or recommend a dose of any medication. Those decisions belong to your prescriber.

Questions.

Both systems arrive in one PDF: the Protect System first, then the Grow System. It’s 128 pages. Instant delivery to your inbox. Start with the Protect System that evening: the safety check, your protein target, the Week 0 card and your 3 session days take about 20 minutes.

If the weight is still coming off, you start with the Protect System. If it has settled, the Grow System’s readiness check tells you whether to start building. Either way, you have both.

At the end of a Protect block, run the readiness check: if you’re ready, you start building. If you’re not, you keep your protein target and check again in 4 to 8 weeks. Any change to your medication is your prescriber’s decision.

Not for the Protect phase: its sessions run at home, 3 times a week, in about 30 minutes. The Grow System is a beginner-friendly gym plan, machines first, for when you’re ready.

No. Both Measure chapters work with any 8-electrode scale, a tape measure and a sit-to-stand test. The Orvi Body Scan is the recommended instrument, and you can add it above.

Each file opens with a 2-minute safety check, and the Grow System runs its own before the heavier work. Check with your clinician before you start if you have kidney or liver disease, a protein-restricted diet, a history of bariatric surgery or disordered eating, if you’re pregnant, or if you take insulin or a sulfonylurea.

The Grow System’s last chapter, Stepping down, is written for the day a dose decision arrives. It never sets or alters a dose; that’s your prescriber’s decision.

The Protect & Grow System comes with a 100-day guarantee. If it isn’t for you, email hello@getorvi.com and we’ll organize a refund, and you keep the files either way. If you added the Scan, the 100 days run from the day it arrives.

Nobody is watching the muscle.

Not the trial. Not the clinic.

Not the scale in your bathroom.

These files are how you watch it yourself.
