Before & After on GLP-1s: What to Expect

Hi everyone! I'm still pretty new to all this, but I've been reading a ton of posts and progress threads and wanted to put together something helpful about BEFORE & AFTER expectations on GLP-1 medications (semaglutide, tirzepatide, retatrutide, etc.). I see so many people say "I don't see a difference" even when they've lost a lot, and others wondering if certain add-ons actually work because there aren't clear photos.

So this is a big summary of what I've learned from our community and what people commonly experience.

1. THE MENTAL SIDE: "I DON'T SEE IT" IS COMMON

One of the most repeated themes in before/after posts is this:

- Person loses 40, 60, even 100+ pounds
- They post comparison photos
- They say: "I still don't see much of a difference"

Meanwhile, everyone else sees a dramatic change.

Why does this happen?

  • We look at ourselves every day, so changes feel gradual.
  • We are often our own harshest critics.
  • Body dysmorphia and perfectionism can distort progress.
  • We focus on what is still "wrong" instead of what improved.

I've seen someone go from 276 lbs to 129 lbs at 4'10" and still talk about the last 7 pounds. I've seen people lose 50-60 lbs and still fixate on their thighs or stomach.

The takeaway: your brain may lag behind your body.

Practical tip:

  • Take progress photos from multiple angles (front, side, back).
  • Wear the same outfit every 4 weeks.
  • Track measurements (waist, hips, thighs).
  • Compare photos side by side instead of relying on memory.

Clothes fitting differently is often noticed before the mirror "catches up."

2. REALISTIC FAT LOSS EXPECTATIONS

Results vary based on:

  • Starting weight
  • Height
  • Dose
  • Activity level
  • Protein intake and resistance training

Examples we've seen in the community:

- 27-28 lbs lost in about 80 days on retatrutide
- 60 lbs lost over 6 months
- 100+ lbs lost over 18-24 months

A common pattern:

  • Steady fat loss of 0.5-2 lbs per week
  • Faster at higher starting weights
  • Slower as you get leaner

If you're already lean (for example mid-to-high teens body fat), further fat loss becomes slower and more visually subtle. Someone at 17-18% body fat will see much smaller visual changes going to 14% than someone going from 35% to 25%.

This leads to the "I'm lean but not lean enough" frustration.

3. BODY FAT VS SCALE WEIGHT

A big issue in before/after comparisons is confusing scale weight with body composition.

For example:

- Height: 5'10"
- Weight: 144 lbs

At that size, someone may already be relatively lean but still feel they have love handles or lack visible abs. Visible abs for many men require roughly 10-14% body fat (varies individually).

Important: as you approach lower body fat percentages:

  • Progress slows.
  • Hunger may increase.
  • Resistance training becomes more important.
  • Sleep and recovery matter more.

Medication alone won't "sculpt" you. It reduces fat mass. Muscle definition requires resistance training.

4. DOSE MATTERS (AND SO DOES PATIENCE)

GLP-1 medications work differently depending on the molecule:

  • Semaglutide: strong appetite suppression and delayed gastric emptying
  • Tirzepatide: dual incretin effect, appetite + metabolic improvements
  • Retatrutide: triple agonist, less purely appetite-driven for some

Some users switching from tirzepatide to retatrutide report:

- Less immediate appetite suppression
- More gradual hunger dampening as dose increases

It is common for hunger suppression to improve with dose titration.

General principles (always follow your clinician's plan):

  • Start low to minimize side effects.
  • Increase slowly.
  • Do not jump doses based on one hungry week.
  • Stay at a dose that works until it stops working.

Some people stay on very low doses (like 0.25 mg semaglutide) long-term because it works for them. Others require higher maintenance doses.

More is not automatically better.

5. SIDE EFFECTS AND HOW PEOPLE MANAGE THEM

Common:

  • Nausea
  • Early fullness
  • Constipation
  • Fatigue

Community strategies (not medical advice, just commonly reported):

  • Smaller meals
  • Higher protein intake
  • Hydration + electrolytes
  • Ginger for mild nausea
  • Avoiding high-fat large meals early in treatment

Many report that gastric side effects fade over time.

If hunger increases suddenly, consider:

  • Are you under-eating protein?
  • Are you sleeping poorly?
  • Are you at a very low body fat now?
  • Has your body adapted to the dose?

Always discuss dose adjustments with a provider.

6. SKIN, STRETCH MARKS, AND "GLOW" ADD-ONS

A frequent question: where are the before/after photos for skin improvement stacks?

The honest answer: true standardized before/after photos are rare.

Reported benefits from community members include:

  • Lightening of sun spots
  • Reduced under-eye darkness
  • Softer appearance of scars
  • Stretch marks losing red/purple tone (but not disappearing)
  • Improved skin firmness

Important distinctions:

- Stretch marks usually do not vanish.
- They may fade or become less noticeable.
- Effects can be subtle and gradual.

People often say: "I didn't realize it was working until one day I noticed something changed."

If you're trying any adjunct therapy for skin or recovery:

  • Take clear, well-lit baseline photos.
  • Use the same lighting monthly.
  • Track specific spots (scars, sun damage, etc.).

Otherwise you may not perceive incremental changes.

7. INJURY, TENDONS, AND RECOVERY

Some users report improvements in:

  • Chronic tendon pain
  • Bursitis
  • Joint discomfort

This may be related to:

  • Weight loss reducing joint load
  • Reduced systemic inflammation
  • Improved metabolic health

But we cannot assume direct healing effects without stronger evidence. Weight loss alone significantly reduces stress on joints, especially knees, hips, and back.

8. WHEN YOU ARE CLOSE TO GOAL

Common scenario:

- Down 70+ lbs
- Within 5-10 lbs of goal
- Suddenly more critical than ever

At this stage:

  • Loss slows.
  • Small fluctuations feel bigger.
  • You may decide to revise your goal lower.

Be cautious about constantly moving the goalpost.

Ask yourself:

  • Is my blood work improved?
  • Is my mobility better?
  • Is my quality of life better?
  • Am I strong?
  • Can I sustain this long-term?

Maintenance is a skill.

9. COMMON BEFORE/AFTER QUESTIONS

"How long did it take?"

Anywhere from months to two years for very large losses. Slow and steady is common and often healthier.

"Will I look younger?"

Many people report looking younger after significant weight loss due to:

  • Reduced inflammation
  • Better metabolic markers
  • Improved mobility and posture
  • More confidence

"Will cellulite go away?"

Often reduced, not eliminated. Fat loss changes distribution and skin tension.

"Why don't I have abs yet?"

Likely:

  • Body fat still above your personal threshold
  • Insufficient core muscle development
  • Genetic fat distribution patterns

Medication reduces fat; training builds visible muscle.

10. FINAL ADVICE FOR ANYONE STARTING

If you're at the beginning:

  • Take photos now, even if you hate them.
  • Take measurements.
  • Set a health-based goal, not just an aesthetic one.
  • Expect your brain to resist seeing progress.
  • Be patient with dose titration.

If you're mid-journey:

  • Compare photos side by side.
  • Celebrate non-scale victories.
  • Lift weights if possible.
  • Eat enough protein.

If you're near goal:

  • Start planning maintenance.
  • Decide what "enough" looks like.
  • Avoid chasing perfection.

Before & after photos are powerful. But how you feel, how your labs look, and how your life functions matter more than a side-by-side image.

I'd love to hear from people at different stages: early, mid, maintenance, super-lean, skin changes, injury recovery, etc. What surprised you most about your own before & after?
 
Great write up, seriously.

This hit. I'm down about 30 lbs and still grab the same size shirts out of habit. My wife keeps telling me they look baggy. The mind thing is real.

Question for you - do you think hunger coming back automatically means it's time to increase dose? Or could it just be that I'm leaner now and my body is fighting back a bit?
 
Thank you for such a thoughtful overview.

To add a clinical perspective: as body fat decreases, circulating leptin levels fall, which can increase hunger independent of medication dose. So

does not always mean treatment failure.

Before increasing dose, I usually suggest patients review:
- Protein intake (1.2-1.6 g/kg for those resistance training)
- Sleep duration
- Stress levels
- Menstrual cycle phase (for women)

Dose escalation should be individualized and supervised. Appetite returning mildly is physiologically normal during fat loss.
 
Solid post.

I'll add something for the guys chasing 10-12% body fat. When you're already in the mid-teens, the last few % are way more about training and consistency than meds.

I stayed on the same dose for months and focused on progressive overload and steps. That's when abs started showing, not when I bumped the medication.

Also agree 100% on photos. I thought nothing was happening until I compared month 1 to month 4 side by side.
 
I love that you included the skin section.

This was my experience too. The red/purple tone faded a lot after weight loss and some supportive skincare, but the lines are still there. They're just softer and less angry looking.

I wish I had taken proper before photos of my sun spots because they absolutely lightened over time and I almost gaslit myself into thinking I imagined it.
 
Maintenance voice here.

The part about moving the goalpost is so real. I hit my original goal, then immediately decided I "needed" 10 more pounds off. In hindsight, I just wasn't used to seeing myself smaller.

What helped me was shifting from weight goals to performance goals (pull-ups, deadlift numbers, resting heart rate). That stabilized my mindset way more than chasing a lower number.
 
Very balanced post.

One thing I'd emphasize from a physiology standpoint: these medications reduce energy intake primarily, but they do not override adaptive thermogenesis entirely. As weight drops, total daily energy expenditure drops as well.

So when people compare a 30 lb loss phase to a final 5 lb phase, they are not metabolically equivalent situations. Expectations should adjust accordingly.

Appreciate that you framed this around sustainability rather than extremes.
 
These replies are so helpful, thank you all.

That makes so much sense. I hadn't even thought about the hormone side of it beyond "drug suppresses appetite."

Also really appreciate the maintenance perspectives. I'm not there yet, but I'm trying to think long term instead of just "how fast can I get there."
 
Weigh first thing AM, post bathroom, nothing else. Salt adds instant water weight. Log daily, average weekly for patterns.
 
Were the injections at that dose giving you weird dreams? I was thinking of starting at 1mg in late March, after I finish my other protocol first.
 
At 0.5mg for six weeks after four weeks at 0.25mg. Down 12 pounds total. Shot my first 1.0mg dose just hours back. Ate only a quarter of breakfast before stuffed. I'm shocked - wasn't anticipating such a dramatic response.
