Age: 29

Weight: down from 139.4 kg (307 lbs) to 110.2 kg (243 lbs)

Height: 6'1"

Body Fat % (BIA Scales): 42% down to 29.1% - and obviously these readings aren't worth much

Waist (belly button): 48" shrinking to 43"

Commencement / 1st pin: a split 2 mg dose on March 16th 2026

Titration Schedule: Accelerated (stepped to 4 mg at the 2 week point, 8 mg at 4 weeks, 12 mg at 5 weeks, and settled on one weekly dose from week 6)

My lifestyle did a complete 180, so I can't put all of this progress down to reta. After a decade on cigarettes, for instance, I went cold turkey 341 days ago (yes, I'm tracking 😅), so there's obviously a great deal of repair happening underneath, which muddies which change is doing what.

On top of that, I mean to keep adding and sharpening lifestyle measures, which makes it even harder to isolate what reta is contributing going forward.

Even so, while the appetite suppression does not feel the way I'd pictured, my logged calorie intake (tracked religiously in Snap Calorie for the last 64 days) does look like someone who is responding.

As before, pulling apart whether the tracking itself made me aware of calories and thus eat less, versus the suppression quietening the food noise enough that a low-calorie day stops being miserable, is no easy thing; I also weigh myself every morning, so how much of this is behaviour and how much is the substance is hard to say.

Diet:

My macros are not being hit (largely a protein deficiency), but the shift has been towards whole foods almost entirely. Processed junk now disgusts me in a way it never used to, and the reta is the only thing I can connect that to. Then again, getting macros right is tough when a normal day for me is ~800 calories. Buying 5 kg of chocolate whey powder from Bulk was a mistake — since starting reta I can barely get it down; unflavoured next time.

Supplements & Other Meds:

1 pill of Healthspan Multivitamin Gold

1 pill of Nutrition Geeks Vitamin D3 4000 iu & Vitamin K2 100μg

2 capsules of Nutravita Omega 3 Fish Oil 2000 mg capsules w/ 660 mg EPA & 440 mg DHA

2 capsules of WeightWorld NAC 600 mg

2 capsules of SportsSupplies Magnesium Glycinate providing 315 mg Elemental Magnesium & Vitamin B6

3 scoops (~15 grams) of Nutrition Geeks Creatine Monohydrate

1 capsule of Dutasteride 0.5 mg

1 pill of Minoxidil 2.5 mg

Fitness:

A heavily modified GZCLP 3-day program (only the T1 & T2 movements, rep schema and periodization are retained; T3s run as giant sets/circuits with less bodybuilding and more functional work using ATG standards, isometrics, kb stuff, etc.), done on Mondays, Wednesdays and Fridays, about 100 mins end to end. Home gym.

Boostcamp was my tracking app, but I've let it slide, since the free tier won't take more than a couple of custom T3s; I need to pick it up again and possibly pay for the subscription.

That's about the whole picture, aside from steps. Stacking every training modality at once struck me as a fast route to burnout, so this will be built out considerably — dedicated zone 4/5 cardio and so on.

Brilliant progress! Really encouraging to read. I also rate that your d3 supp comes with k2 alongside it. Plenty of people have no idea that k2 is what makes d3 absorbable, and they take d3 on its own with next to no benefit.
 
Wow. You're doing great — a perfect example of diving in with both feet. Normally I'd say you're shedding weight too fast, but that doesn't apply here. You're attacking this from every direction at once.

Do you have a goal weight in mind?

And do you have a plan for which of these big lifestyle changes you'll ease off once the goal is reached? Given how well you're doing, that exit strategy will be needed before long.

Thanks!

I'd have to agree. I know I came down far too quickly, but I'm a bit reckless and I get a kick out of pointless risk. Moderation isn't really my thing.

On exit strategy — I'm assuming you mean calories and reta use? I want to land at 12% bf (no particular reason), and once I'm there the plan is to move to maintenance calories and get the macros sorted.

Stopping the reta isn't part of it, though... I want to experiment and work out my minimum effective dose (something I skipped during titration because I hurried it), and maybe try stretching the gaps out to every 2 weeks.

I've read about therapeutic effects of glp1s that have nothing to do with weight. Chondroprotection, tendon matrix remodelling, anti-inflammatory action generally.

Don't want to miss out on any of that.

Sounds like our thinking runs along the same lines.

To me, exit strategy covers whatever you plan to change once you get there. For a lot of people I'd assume that means dropping the glp's entirely. But I'm with you. Chances are I'll be on reta in some form for good, for the same reasons you listed. My plan is to keep training, keep the reta, and probably start adding things back into what I eat.

You're doing great — thanks for sharing
 
Nice work. As you get closer to target the rate of loss will taper off, unless you cut calories further, and that may not be tolerable enough to be worth it. Much the same happened to me: 6kg/month for the first 55kg or so, going from 145 down to 90kg, and then it slowed.

Mine was done without reta and with very little exercise, both of which help hold energy expenditure up as the weight comes off.

A BMI of 25 at 6' is about 80kg, which I'm guessing is roughly where you're aiming, so 59kg less, or about 44% down from 135kg. That's more than the 29% average in the best reta study, but you're doing well enough so far that you may still get there before the plateau arrives, and then you can work out what comes next.

Amazing, well done 👍

What did your weight loss trajectory look like once you started? When did the drop begin to slow?
Thanks!

I didn't track consistently through last year, but I do have a few entries — the lowest being 126.2 kg on November 22nd 2025.

I quit smoking in the summer (mid-August) of last year and put on a good chunk of weight, though I've no figures for it; safe to say I was under 120 kg before I stopped.

The peak came in March this year at 139.4 kg, the same month I began the reta.

The line graph I posted shows my weight climbing through last year, with nothing recorded for January or February, and then a sharp month-on-month fall from that point on.

Cheers mate.

Congrats to you too! 55 kg with no glp1 can't have been easy.

Ye, I fully expect a plateau to arrive sooner rather than later. I'll deal with that when I reach it...

Cheers mate — the smoking is another one I'll have to deal with! I've managed it before, though that was a fair while ago. Best to wait until my weight is somewhere near, since I tend to go all in and try to fix everything at the same time, and then of course fail at the lot of them 😆
