Tirzepatide Possibilities??????

38 replies24 peopleJun 4, 2026☆ Follow
Summary

What realistic weight loss can a 370 lb sedentary man expect on tirzepatide over one year while adding sustainable diet and exercise?

Users report highly variable results on tirzepatide, with many losing 15-30% of starting body weight in a year through reduced appetite and portion sizes rather than strict calorie counting. Personal accounts range from 20 lbs in six weeks to 91-100 lbs in twelve months, with faster initial drops from water weight and non-linear progress thereafter. Several switched to or prefer retatrutide for greater total loss despite subtler appetite effects, while others emphasize that sustainable habits like consistent walking, protein focus, and repeatable meals matter more than intensity. Individual response, tolerance, and prior GLP-1 exposure strongly influence outcomes.

What this discussion establishesWhere people disagree

Whether retatrutide's appetite suppression is meaningfully weaker than tirzepatide's while still driving superior weight loss

Still open

How much any single new user will lose, given large individual differences and the need to test personal response

Nothing here is advice.

Background: 42-year-old male, 6'2", currently 370 pounds. On tirzepatide for a full year, what kind of weight loss is realistic? I'm mostly at a desk now but enjoy lifting, so adding workouts won't be an issue. I'm also building a diet I can actually maintain. Past attempts failed because I went too hard on exercise and cardio and couldn't keep it up. Looking for guidance.

With a workable diet and exercise plan you could drop quite a bit. Similar situation here, 41M, 6'4", started around 330. Been increasing tirz for about six weeks, eating better and doing light workouts to avoid overloading myself. Already down 20 pounds. Results will differ for everyone.

Trial data shows average losses at different time points. At 370 pounds and wanting substantial reduction, retatrutide might be worth considering. A steady one percent per week can be sustainable for long stretches; I've kept that pace for nearly six months. Early weeks usually see bigger drops from water. No need for heavy restriction diets. Focus on protein while still getting carbs and fats, and keep life enjoyable where possible.

Started tirzepatide in December 2024 at 335 pounds (6'4") and reached 244 by December 2025, a 91-pound drop or 27 percent. Your starting weight is higher, so scaling that percentage suggests roughly 100 pounds in a year is possible. Still, I agree with the suggestion to look at retatrutide if available; I would have chosen it over tirzepatide.

Tirz reduces the mental effort around food so better choices come easier. I settled on a few repeatable meals: turkey meatballs with zoodles and peppers plus premade marinara, air-fried chicken breasts with a spinach-strawberry salad and light dressing, and rotating Taylor Farms kits or baguettes. Having four solid options makes daily decisions simple and keeps things sustainable.

Exactly. I can eat what I want now because preferences shifted and greasy or fried items lost appeal. Portions naturally shrank; I used to plate too much and waste half. Fullness hits faster, and overeating leads to discomfort later. It's more than just quieter food thoughts; tastes and habits changed. Steak is still good but only in small amounts, and I eat just a few fries.

68-year-old female, started GLP-1s June 2025 at 393 pounds. Now at 323 after one year, mostly on tirzepatide, with no calorie tracking or added exercise. That's 70 pounds or 17.8 percent despite hormone issues, AFib, gout, CKD, and other conditions. Progress was far from steady. For a man without those complications, 100 pounds in a year seems reasonable.

LevelThistle44archiveJun 4

If charts are the topic, mine shows tirz for the first month then a switch to reta. Linear regression puts average loss at 0.35 pounds per day.

Solid progress. The chart shows the difference clearly: reta produced a steep drop while tirz was much gentler.

GreyAlder46archiveJun 4

The program you'll actually do is the best one. So far I've managed only occasional walks, around 5,000 steps even indoors. Bought a VR headset that mostly sits unused. Not a gym person and no space for equipment anyway. Considered a wall-mounted system because I like gadgets, but procrastination wins. Just one more peptide to consider.

6'4", 54-year-old male, started at 350, now 220 with a goal of 190. Began tirz July 2024, switched to reta after two months, reached 225 in about a year with no diet or exercise changes. Appetite control faded after roughly a year, so added another compound and have held 220-225 since. Current doses are 12 mg reta weekly and 2.25 mg of the other split.

You've seen the stories; it has to be experienced. Started at 330, down to 270 after a year without workouts. Daily tasks provide enough activity. It really teaches portion control.

LevelWillow41archiveJun 5

Like most here, diet isn't a big concern; I eat what I can manage. Average responders should see 15-30 percent body-weight loss. Prioritize 8,000 steps daily over lifting while in a deficit, though lifting is fine if you enjoy it. It comes second to movement for now.

PlainQuill53archiveJun 5

Younger at 34 and taller at 6'4", started at 325 and added tirz around 260 when progress stalled. Reached 191 yesterday after roughly two years total.

CopperSignal27archiveJun 5

Good luck. I used GLP-1s only after dropping from 145 kg to 75 kg on my own. They help keep weight off far better than past attempts, where regain was common. Staying on them long-term makes maintenance realistic, unlike even surgery in some cases. Individual responses vary widely: a small group loses little, others drop a lot on low doses, and some face side effects. You have to start and titrate to see where you land.

Congrats on the 134-pound loss. Also 6'4" and started a bit heavier at 335 with a goal of 205, but seeing your results in the low 190s makes me wonder if 205 will be enough. How did you look and feel at that weight given your frame?

GreyMarble68archiveJun 5

The stories are motivating. My main worry is the reported difference in appetite suppression between tirzepatide and reta. I've heard reta's effect is weaker. Is that accurate?

WarmAnchor46archiveJun 5

Cut salt, oil, and sugar. Skip processed junk. Aim for 150-200 g protein daily and track only that. Fast 12-14 hours, working toward 16. Gym isn't an issue, so do four hours of weights weekly split upper and lower. Build to 10k steps most days. Combine all that with tirzepatide and health should improve noticeably in months.

WarmMeadow92archiveJun 5

I get the concern, but retatrutide tends to produce better overall results for most people even if appetite suppression feels less intense. The three-receptor action drives more metabolic change beyond just hunger. Many describe it as naturally eating less without the complete "food doesn't exist" feeling. It's a different mechanism that still delivers superior loss. The main potential downside is increased resting heart rate for some.

What differences did you notice between tirz and reta?

LevelThistle44archiveJun 5

Only on tirz briefly as my first month, so no useful comparison to share.

Yes, lost 115 pounds from August 2025 to May 2026, gained a little back while pausing for procedures. Still a large percentage in nine months.

Reta didn't work for me personally. Whether I used it long enough or tried different sources is unknown, so the choice remains individual.

CopperSignal27archiveJun 6
↳ replying to @GreyMarble68

The frequent claim that reta reduces appetite less than tirz yet still causes more loss is interesting because studies show greater weight reduction. The practical difference in appetite effect may not be large. The extra glucagon activity could raise expenditure by roughly 100 kcal daily, accounting for about five extra kilos lost per year, which matches the observed gap between 29 percent and 24-25 percent. Higher expenditure could allow slightly more intake while still producing more loss.

RustBramble70archiveJun 10
↳ replying to @CopperSignal27

Good point. Keep changes simple so they stick and goals stay reachable. On the food side, limit sugary, fatty, and heavily processed items; these medications generally make that easier. Reta did that for me.

RustBramble70archiveJun 10

No direct comparison since I've only used reta. At low doses food noise vanished quickly. Down 30 pounds in three months on 2-2.5 mg every few days. Avoiding former favorites like certain candy bars takes almost no effort. Kept existing resistance training; workouts feel better, likely from the weight loss itself. Because reta loss includes fat, muscle, and bone, protecting muscle through lifting matters. Best of luck.

The most sustainable diet adds foods rather than removes them: more protein or produce instead of chips. Track within a calorie target but repeat meals you enjoy, especially for office days. Added low-intensity walking on lunch breaks to raise expenditure without increasing hunger. Goal is overall health, not just scale weight. Started at 43 percent body fat in late March and have seen about 20 pounds lost so far. Monthly progress continues.

KeenHarbour69archiveJun 10

That 20 pounds is still great progress. Keep going.

NorthWillow72archiveJun 10

On tirz I averaged about two pounds weekly. Aimed for normal BMI rather than an arbitrary number. Retatrutide may raise heart rate, so monitor if choosing it, though trials showed higher total percentage loss. Tirz worked well for me, around 25 percent in seven months.

BrightThistle70archiveJun 10

Older and started heavier than you, yet tirz has been excellent. 6'2", 55, began at 386 in early May on low dose, now up to next level, down 26 pounds in five weeks. No workouts, desk job. Diet shifted easily; cravings for fried foods disappeared and no junk at home. Meals are mostly salads, raw vegetables, certain soups, fruit smoothies, and minimal meat. Added B12, magnesium, collagen, and casein for support.

Protein timing doesn't affect muscle outcomes much; total daily amount matters more. Only adjust timing if it helps control hunger around workouts.

BlueSparrow66archiveJun 11

Get 4-6k steps at work with little strength training. Dropped from 237 to 200 in about two months on tirz with almost no other changes, now maintaining on 7.5-12 mg as needed for food noise. Lifestyle adjustments can produce even larger losses depending on tolerance. Watch speed of loss to avoid issues from rapid change or malnutrition; a multivitamin helps.

GreyMarble68archiveJun 12

Main worry with reta is the reportedly weaker appetite and food-noise control. What's your experience? Also, nice work on the loss.

SteadyLedger49archiveJun 12

Everyone responds differently, so don't set limits based on others. Started at 445, 6'1", 61 years old, now 210 and still dropping. Made lifestyle and intake changes. Sequence was sema, then tirz, then reta.

ClearHarbour45archiveJun 12

Not sure what the low starting dose will do, but once at 5 or 7.5 mg most people find avoiding 60 pounds in four months would require deliberate effort.

WarmMeadow92archiveJun 13
↳ replying to @GreyMarble68

No argument here. Tirz works well and I like how it feels. You used it a couple years ago for a couple months and lost 35 pounds, so your body responds. Prior use can mean needing higher doses when restarting, but many regain effectiveness at those levels.
