Aggression in GLP-Fueled Weight Loss

Summary

experiences with fast versus moderate weight loss rates on GLP medications and associated side effects

Forum users shared personal accounts of losing 50-100+ pounds on tirzepatide or retatrutide at varying speeds. Many reported 1-2 pounds per week as a common target to limit loose skin, muscle loss, and gallbladder problems, though some achieved faster results with few issues while others regretted rapid drops. Dosing often stayed at standard levels or increased only when hunger returned, and several noted that genetics, age, and prior weight duration influenced skin outcomes more than pace alone. Maintenance after reaching goal weight and whether to stay on medication long-term remained open topics.

What this discussion establishesWhere people disagree

Whether losing weight more slowly meaningfully reduces loose skin or if genetics and age dominate; also whether most people can successfully stop GLP drugs without regaining weight

Still open

Best way to transition off medication while keeping results, and how much individual response can be predicted in advance

Nothing here is advice.

I've come across multiple accounts of people taking a very aggressive route with their weight loss, and it seems this carries more risk of serious side effects plus a greater likelihood of putting the weight back on. I won't pin down an exact definition because that might shut some people out, but I'd really like to read stories from folks who dropped 50 pounds or more without pushing doses up fast or following extreme eating plans.

I dropped around 75 pounds. At first the pounds came off without much effort while I was on 15 mg of tirz. I responded really well. I also did intermittent fasting, eating only after 4 PM until midnight when I felt hungry. A year later I'd reached most of my target, about 65 pounds down, but I still wanted to see my abs, so another 15 pounds remained. I raised the tirz dose to finish that off, going up to 30 mg even though I knew it was high, and that got me the last 10 pounds. I just did that recently and plan to drop back to 15 mg for maintenance. Overall I've lost about 30 percent of my starting body weight. No loose skin so far. I needed the higher dose to move past a plateau, but maintenance at the lower dose is the next test. Happy to answer questions.

My clinic provider mentioned the sweet spot is 1-2 pounds per week. Worth taking lightly, but I've seen that figure come up more than once.

PatientBeacon15archiveJul 8

If I could go back I'd probably move a little slower. Skin needs time to adjust and the whole body takes extra stress. Still, I'm glad I reached my goal weight sooner. Patience isn't my strong suit.

GreyAlder39archiveJul 8

I didn't follow any extreme diet. Several days a week I can barely eat, and sometimes what I do take in doesn't sit right and comes back out.

Rs is nearing 98 pounds lost now. At this stage my stamina and strength are solid enough that I'd have to do something pretty reckless to force more weight off each week. Rs does 20 to 50 miles on an exercise bike plus upper-body work every day while holding an 800-calorie deficit. No soreness, no energy drop, no hunger. It's both good and odd at the same time. The weight seems to come off faster right after I open a new vial.

Why choose 30 mg of tirz instead of adding cagri or Elora or switching to reta? I've only heard of people going to 20-25 mg at most.

PatientMeadow76archiveJul 8

I've lost over 60 pounds since late October and have maybe 10-15 more to go, though belly fat is hanging on. I'm at 4.5 mg twice a week and only raise the dose when uncontrollable snacking starts happening. Early loss was 4-5 pounds the first couple weeks, then settled around 2 pounds, then 1 pound, and lately almost stalled before a 1-pound week again. I think the body is pushing back now that I'm near a normal BMI. I'm resisting the urge to just increase and giving it time instead so I can stay on a lower dose. Calories sit around 1400-1600 on run days. I lift dumbbells and use bands five days a week. I eat lots of chicken, eggs, veggies, salad, and some carbs to keep energy up rather than crash calories and risk muscle.

CopperBeacon14archiveJul 8

I'm at 81 pounds lost since about this time last year. Started naturally, moved to pharmacy tirz, then gray around November 2025. Most of the 70-ish pounds came off after November, roughly 2.3 pounds a week. That feels average to slightly aggressive. I'd suggest going slower because the sides like loose skin, nausea, and fatigue have been rough.

GreyHarbour88archiveJul 8

I've lost about 70 pounds in a year while staying busy with house projects and yard work but without gym time. Average weekly rate came to 1.38 pounds, with big early losses and now sometimes only 3 pounds a month. Started on tirz, added reta, and slowly shifted over. No tesa or cagri. Haven't had the worst sides people mention. Not at goal yet, so sometimes I wonder if I should have pushed harder, though that feeling probably comes from social media. In my 50s I have some loose skin where old stretch marks are. Every body reacts differently so you just have to try and see.

It's the opposite of what you asked, but I can confirm the risk. I lost 33 pounds in four months on reta at 2.33 mg then 4.66 mg per week and ended up with gallbladder trouble I'm trying to handle without surgery. Dropping the dose has helped.

LevelThistle44archiveJul 8

I've lost 70 pounds in 200 days at about 1 percent body weight per week with an average 1100-calorie deficit. Never threw up, just felt off for a couple days when I first tried 0.25 mg sema. Splitting to 0.125 mg twice a week fixed it. Sleep isn't perfect but it's fine. I stopped worrying about the Oura sleep debt number and that helped. I still track it though. I'm on plenty of reta with almost no bad sides and can eat or do whatever I want, so I don't see it as overly aggressive. Faster loss does raise the chance of gallbladder trouble, extra muscle loss, hair issues, or bone density drops. Higher regain risk only makes sense if someone quits the habits that created the loss.

BrightSparrow36archiveJul 8

I'm not dropping weight any faster on GLPs than I did before with just the loseit app and walking. I've usually managed about 10 pounds a month, which for me was often around 1 percent of body weight per week. Some weeks 1 pound, others 3 or 4, but it averages out. On GLPs the process feels far less intense. Without them I needed total focus on calories and movement. Now both feel normal and automatic. I'm down 56 pounds since mid-February on 7.5 mg tirz plus 2 mg reta and want to lose another 25. It seems doable.

KeenPebble33archiveJul 8

You can go slower if you prefer and you'll probably hold on to more muscle. But there's no proof that slower loss changes how skin tightens. That seems mostly down to genetics and age. I've seen 20-year-olds with loose skin after 100 pounds and at 48 I'm at 75 pounds lost with none showing. Genetics appear to matter most from what I've noticed.

KeenPebble33archiveJul 8
↳ replying to @SteadyAnchor13

Tirz worked well for me. Lilly is looking at higher doses. I tried cagri but the effect faded after a couple months. Tracking everything showed no difference once I stopped it, and it made me more tired than tirz so not worth it. Elora wasn't around when I needed it. Low-dose reta actually increased my hunger. Since fasting worked I stayed with tirz. I've seen people here go to 60 mg for big losses. 30 mg got me 30 percent body-weight loss, which is on the high side. I'll drop to 15 mg soon and check maintenance.

PatientBeacon15archiveJul 8
↳ replying to @KeenPebble33

I used to think the same. WebMD lists how fast you lose, the total percentage lost, how long you carried the extra weight, plus genetics and age as factors for loose skin.

I have no patience and felt like a failure for a while because it took a year and a half to lose 90 pounds. Looking back I'm glad I went slow. I probably would have more loose or sagging skin otherwise. Losing only 1-2 pounds a week, sometimes none, helped avoid hair loss, extra muscle loss, gallbladder trouble, and other rapid-loss sides. I kept reminding myself slow and steady wins and it seems to have paid off.

KeenPebble33archiveJul 9
↳ replying to @PatientBeacon15

You're probably right, though I still wonder how much each factor contributes. Genetics and time spent at higher weight seem like the biggest drivers based on what I've seen.

WryHarbour43archiveJul 11

I'm down 41 pounds, 15.5 percent of starting weight, in six months on 10 mg tirz. I tried to stay on the lowest effective dose instead of following a fixed schedule. My average pace stayed in the generally accepted safe range, on the lower side at about 0.6 percent body weight per week. I got frustrated at times and wanted to move faster, but overall I'm happy with how it went. I lost a little off my max bench, which is annoying but minor. No loose skin, good labs, no major sides. I think pushing harder would have cost more muscle.

CopperSignal27archiveJul 12

It's hard to predict how any one person will respond to these drugs for side effects or for appetite and weight-loss benefits. The doses you end up needing depend on your own reaction as you adjust. You can ramp quickly and face higher side-effect risk, or treat it like a regular diet and cut calories hard even without much appetite suppression. Either way, for meaningful loss the key is making the process something you can stick with long term. Maintenance is the toughest part and has to stay tolerable. With GLPs you might only need to lose once if you stay on them. Starting with the standard dosing schedule is straightforward and fairly low risk. If loss is too fast you can slow it to reduce gallstone chances, but mostly it comes down to sustainability.

My mom had surgery for weight loss and it damaged her gallbladder, so that's one risk I'm especially concerned about with aggressive approaches.

ClearPebble66archiveJul 12
↳ replying to @LevelThistle44

I'm not eager to stay on a GLP-1 for life, especially in my 20s, so old habits are a worry. I don't usually struggle with maintenance once the food noise is gone though. Most of my gain happened after I blew out my knee while I was a runner. Using a GLP for 8-12 months as a reset while staying active and watching macros might let me recomp and reach around 200 pounds.

ClearPebble66archiveJul 12
↳ replying to @BrightSparrow36

Congrats on the progress. One thing I've noticed with the non-GLP route is that if weight doesn't come off easily, every single decision has to serve the goal. Helpful story.

The odds don't look great, but good luck anyway. Some people keep losing after they stop. One small study looked at dosing every other week and it worked for many. Surmount-Maintain compared staying at max dose, dropping to 5 mg weekly, or stopping completely. AI summary of the discontinuation data:

BrightThistle70archiveJul 12

I'm on a long path to lose 160 pounds total. Started at 386 and now at 345 after 66 days, which is very fast. Eating well, no sides, normal bathroom habits, 7 hours sleep, and no food noise. Followed the usual 4 weeks at 2.5 mg then 4 at 5 mg and skipped 7.5 mg because hunger was already gone. Moved to 6.25 mg only because the vial is 66 days old and potency might be dropping. Worried about gallbladder but no pain or cramps. Eating 200 g protein daily plus fresh produce, taking magnesium and collagen, swimming and doing resistance work. Adding weights tomorrow. Considering ursodiol for gallbladder protection. Still have 120 pounds to reach 220 at 6'3" and 55 years old.

Don't forget that eating some fat helps keep the gallbladder emptying and lowers stone risk.

QuietSignal61archiveJul 13
↳ replying to @ClearPebble66

Do any of the studies control for diet, habits, and lifestyle? They mostly just give the drug, keep raising the dose until it's too much, then try different ways to stop. The fact that most people regained weight doesn't feel like strong evidence by itself. If stopping always leads to big regain, that would mean the drug does something harmful to the body, and I don't buy that. Lose the weight, build new habits, add muscle, use exercise mimetics if needed, then lower the dose gradually over months or years. If that can't work then these drugs are just a temporary trick and a lifetime medication for obesity.

QuietSignal61archiveJul 13
↳ replying to @NorthWillow72

Olive oil works well for me. One doctor suggested at least 25 g of fat with breakfast, ideally a hot meal within 45 minutes of waking. A swig of vinegar helps too. TUDCA is essential. A can of beans with olive oil did wonders and cut daily attacks to occasional discomfort along with TUDCA, chanca piedra, and a lower reta dose. I wouldn't suggest bacon grease or beef drippings though. Fatty pork and beef bothered my gallbladder, probably from cholesterol, while seed oils didn't. Omega-3s also have some evidence for gallbladder support.

I didn't raise my dose but I was a strong responder and lost over 60 pounds in under 10 months. It's tough to slow down when you've fought for years, but I wish I had because the last 20 pounds really showed in my skin.

CopperSignal27archiveJul 13

That's basically what they were made for, long-term management of obesity or diabetes. Their real strength is sustaining the loss over time, not just causing it. Almost every obese person has lost and regained before, so the hard part is keeping it off. Decades of data show most people struggle with maintenance and only a small percentage succeed long term. These drugs have far higher success rates than anything else short of surgery. If you can build better habits that's great, but for many the medication makes maintenance possible where diet and exercise alone didn't.

LevelThistle44archiveJul 13
↳ replying to @QuietSignal61

Controlling for every lifestyle factor is tough. Some trials offered counseling. The 80 percent who regained at least 25 percent of the loss is a real data point, and average regain around two-thirds of the weight lost is another. The 4 percent who kept losing after stopping is interesting too. Traditional diet and exercise usually gives 5-10 percent loss and leaves people 3-5 percent lighter after five years. GLPs produce bigger losses and the regain data, though newer, tends to plateau around 75 percent. Diet and exercise can absolutely work for some, but the numbers show it's rare at higher loss amounts.

ClearPebble66archiveJul 13

It's striking how much avoiding the worst sides of weight loss comes down to the basic balanced-diet advice from health class: watch macros, hit nutrients, skip empty calories.

ClearPebble66archiveJul 13
↳ replying to @QuietSignal61

Plenty of people have done exactly that and posted on r/GLPgrads, which is part of what makes me willing to try. In a place like the US where poor eating habits are everywhere, it's no surprise many regain without changing daily life. It's like fad diets that drop weight fast but lead to rebound because no real habits changed.

ClearPebble66archiveJul 13
↳ replying to @LevelThistle44

I have some trouble with the idea that after goal weight you just keep doing exactly what you did to lose. Loss, gain, and maintenance are three different states with different needs. Once at goal, recalculating calories for the new metabolic rate and activity level makes more sense. Average people can do remarkable things, and it doesn't take superhuman discipline to improve your life.

ClearPebble66archiveJul 13
↳ replying to @CopperSignal27

This feels more like a reason to be careful when planning to stop rather than a reason to stay on forever. The difficulty of lifestyle change isn't an excuse to skip it.

The best tools are often created for one purpose but used for another. You've basically made my point. No one stays on a statin or blood-pressure med for life unless they truly can't fix the root cause. High blood pressure and poor lipids are usually fixable. A GLP can even help lipids at the same time. The real therapy is managing calories and keeping mind and body healthy so you don't fall back. Not everyone can access or stick with that, but it shouldn't be assumed impossible. GLPs are useful drugs and feel like a free ride for some, but lifetime use shouldn't be treated as automatic just because change is hard for many. Results matter more than original intent.

CopperSignal27archiveJul 13
↳ replying to @ClearPebble66

I'm not saying people shouldn't try to improve habits, just being realistic about decades of research showing most people are poor at long-term weight maintenance. For severe or lifelong obesity the picture is especially clear. I've personally lost over 100 kg to 70 kg range about six times. In 2012 I went from 122 kg to 65 kg and held it a couple years, then reached 145 kg in 2022, got to 75 kg by 2023, and stayed there a year without GLPs. That pattern is common here. Maintaining without the drugs is genuinely difficult even on a high-protein, low-density diet. It took 1600-1800 calories and constant effort. With massive loss, energy expenditure drops from less tissue and metabolic adaptation, plus hunger rises, making regain likely.

QuietSignal61archiveJul 13
↳ replying to @ClearPebble66

The whole thing ends up being pretty straightforward. Back when I struggled with substances, falling into a trap that feels impossible to escape on your own happens fast. I keep thinking these compounds might work like a body-level stand-in for getting locked away by someone until the craving passes and the pattern breaks. All the flashy wrappers, nonstop marketing, and quick comfort from those simple sugars in every color and taste make me uneasy. What concerns me most is whether my ability to hold back urges will stick around once the compounds stop. Avoiding the purchase of certain snacks becomes far simpler right at the start, even though I remain perfectly willing to eat them whenever they happen to be nearby. This route should cut my spending quite a bit across the coming years. Apparently that opinion draws some pushback.

LevelThistle44archiveJul 13
↳ replying to @ClearPebble66

International studies show similar regain patterns, so it's not just a US issue. Across the world most people struggle to build lasting habits for healthy weight. All weight change ultimately comes down to calories in versus out. If you stop balancing that, the weight returns. Extraordinary results are possible but sustained ones are rarer. It's not that I'm special. The basics of eating well and moving are simple, yet hard to maintain for most. The irony if I end up needing emergency gallbladder surgery won't be lost on me. Until then I'll keep a balanced diet and good markers.

Sorry if this sounds blunt, but that view comes from a limited take on maintenance. The statistics aren't just natural outcomes, they're records of choices. People who keep weight off tend to have predictable habits they maintain daily. It's not a fixed percentage destined to succeed or fail. Most chronically obese people I know haven't even completed one full 50-pound loss cycle. They try for weeks or a few months then stop. That's where GLPs help most, by giving a window to rebuild momentum.

CopperSignal27archiveJul 14

Most of what I'm saying fits better with more severe or long-term obesity than with just being overweight. I've read a lot of the research from the last 30-plus years and have personal experience going from over 100 kg to 70 kg about six times. In 2012 I reached 65 kg from 122 kg and held it a couple years, then hit 145 kg in 2022 and got to 75 kg by 2023 without GLPs. That story is common here. Maintaining without the drugs is genuinely hard even on a carefully designed low-hunger diet with high protein, low calorie density, very low fat, and no high-glycemic foods. It required 1600-1800 calories and constant attention.
