A Year on Mounjaro

What a year on tirzepatide actually taught me — written the way I'd write a post-mortem, not a testimonial.

Written on 4 August 2026 — one year to the day since my first dose.

I don't trust easy answers, and a weight-loss drug is about the easiest-sounding answer there is. So before anything else: this was not easy, it was not a shortcut, and if you're reading this hoping for a cheat code, it isn't. It's a tool — a very good one — but a tool you still have to operate. Here's the year, read the way I'd read any system I was responsible for.

The trigger

In May 2025 I did a routine health check, and the numbers came back bad enough that an endocrinologist sat me down and was blunt. Not the usual "you should lose some weight" — people had said that my whole life, and it's easy to tune out. This was specific: HbA1c, thyroid panel, kidney markers, cholesterol. Read together, he told me, I was living in a genuinely risky zone. I was around 132 kg.

He started me on medication — not Mounjaro. I took it. It barely moved the needle. By the time I saw him again on 4 August 2025 I was at 135 kg, going the wrong way. That was the day we started Mounjaro. That was the trigger. Not vanity, not a wedding, not a photo — a set of lab values that said this is now a health problem, not a cosmetic one.

Going in blind

I'm skeptical about everything, and this was an unknown drug in unknown territory for me. There's no manual for your own body, and most of what's online is either hype or fear. So I treated it the way I'd treat any unfamiliar system I'd been handed: instrument it, watch it closely, and figure out its behaviour from the data rather than the marketing.

We started conservative — 2.5 mg for two weeks, then up to 5 mg for another four to six weeks. What surprised me was how early it responded. The weight started dropping after the first or second dose. Inch loss showed up fast, faster than the scale in some ways. My energy went up, not down, which I hadn't expected. And some of the quieter signals of insulin resistance — the dark patches on my skin — began to fade. Other people noticed before I said anything.

Side effects, honestly

I got off comparatively lightly, but "lightly" isn't "nothing," and the posts that pretend it's nothing aren't doing anyone a favour.

The main thing was gut behaviour. Mounjaro slows gastric emptying — that's part of how it works — and your digestive system lets you know. I'd get sharp acidity in the days right after a dose. Bowel behaviour swung between loose motions and stretches of constipation across the week. None of it was severe enough to stop me, but it's real, it's persistent, and you plan around it rather than being ambushed by it. Knowing why it was happening made it manageable instead of alarming.

But the side effect that caught me most off guard wasn't physical at all. Somewhere around the three- or four-month mark, the discipline itself started to wear me down — eating clean and sensibly every single day, with the food noise switched off and none of the old easy comfort in a meal, turns out to be mentally exhausting. This whole thing is a mental game, and the mind fatigues like any other muscle. Nobody warns you about that. What helped was treating it as part of the process rather than a personal failure, and deliberately building some flexibility into the routine before I hit the wall rather than after.

What I'd actually tell someone considering it

This drug should be gatekept, and I'll say that as someone it saved. The cultural drift is toward treating tirzepatide as a vanity accessory — drop three or four kilos before a holiday, borrow a friend's pen, get off it. I think that's a misuse of a serious drug, and I don't think it's a close call. This is not a cosmetic tool. It's a medical intervention for people whose metabolic markers are heading somewhere dangerous, and every casual recreational user makes it a little harder to defend for the people who actually need it — on cost, on supply, on stigma. If your doctor looked at your labs and said you're at risk, this is a serious answer. If you just want to look better in a photo, you're playing with something you don't need, and you're not prepared for what it takes to run it properly. Treat it as a lifestyle you're committing to, not a season you're passing through. If you're not ready for that, you're using it wrong.

The mindset is the whole game. Here's the part people get backwards. Mounjaro does one thing exceptionally well: it turns down the food noise — that constant background hum of wanting to eat that has nothing to do with actual hunger. What it doesn't do is decide for you. It gives you honest hunger signals instead of noise, and the work — and it is work — is learning to trust those signals: to eat when your body genuinely asks, and to stop treating food as the reflexive answer to every impulse. Respect what the drug is doing rather than fighting it. It's helping you; you have to help it back. It will not do the whole job by itself, and anyone who tells you otherwise is selling something.

One principle worth internalising early, and I learned it the hard way: the drug protects you from hunger, it does not protect your muscle. When the food noise drops, eating far too little becomes effortless — and here is the trap, the weighing scale loves it. Under-eating shows up as fast, satisfying drops every morning, so the exact behaviour that's quietly hurting you is the one that feels most rewarding. Somewhere past the thirty-kilo mark I let myself drift into that zone, and my body answered with muscle and joint pain that had nothing to do with the drug and everything to do with not fuelling myself properly. Do not starve yourself because the scale applauds it. Eat enough, prioritise protein, keep moving. I won't hand you a protocol — that's between you and your doctor, and it's the most over-sold content on the internet — but hold the principle: you want to come out the other side lighter and stronger, not just smaller.

Weigh yourself every morning. The single highest-leverage habit for me was stepping on the scale every day, same conditions, first thing after emptying my bowels. It keeps you honest in a way nothing else does. Once those half-kilo daily losses start showing up on the scale, they give you a kind of motivation that no pep talk ever will. One caveat I didn't invent: the day-to-day number is noisy, and for some people a daily weigh-in becomes a stressor rather than a signal — what actually matters is the trend line, not any single morning. And there's the one thing the scale lies about, which I flagged above: it will happily reward you for starving. Read it for honesty about the trend, not as a judge you're trying to please. For me, watching that line move over weeks was the only motivation that ever truly stuck.

Doing this in India

Almost every honest account of this drug you'll find online is written from the US or the UK — framed around insurance battles, dollar pricing, and a culture that's been arguing about Ozempic at dinner parties for two years. Very little of it is written from here, and the Indian context is different in ways that matter.

Start with the biology, because it's the part most people get dangerously wrong. South Asians develop insulin resistance and type-2 diabetes at lower body weights and lower BMIs than the Western charts assume. "You don't look diabetic" is folk wisdom that has probably hurt more Indians than almost any other sentence. I did not look like an emergency. My labs said otherwise. If you're Indian and someone reassures you based on how you look, ignore them and read your numbers.

Then the money — and this is where Indians do what Indians do best. The sticker price looks frightening, but it overstates what a well-advised patient actually pays, because how you buy matters more than most people realise, and the intuitive choice is usually the expensive one. I'd know: I started out over-cautious, bought the most hand-holding format there is, and paid the most for the privilege. It took me a while — and some wasted money — to get smart about the economics of strength and format. I'm not going to turn this into a step-by-step, because dose and delivery are things you settle with your prescriber, not off a stranger's blog. But the headline number is not the number a savvy, supervised patient ends up paying, so ask your doctor to walk you through the most cost-effective way to buy your dose. India already runs at roughly a third of US pricing. And if your indication is genuinely metabolic — real diabetes markers, not vanity — some chronic-care insurance will reimburse part of it, where they'd touch nothing for a pure weight-loss claim.

The one jugaad I'd tell you to avoid is the tempting one: heavily discounted product from grey-market sellers. Counterfeit pens have been circulating since the drug launched here, and this is a refrigerated injectable — cold-chain isn't optional. Saving money on a fake, or on a vial that sat warm in transit, isn't saving money. Cut cost on format and paperwork; never on the source.

And the stigma, which is its own thing in India. The reflex is that weight is a discipline problem — just do yoga, eat less, have some willpower — and that a drug is cheating. I understand the instinct; I held some of it myself, which is partly why I was so skeptical going in. But I'd reframe it: nobody calls a statin cheating, or thyroid medication cheating. I take Thyronorm every morning and no one blinks. This belongs in the same category — a medical tool for a measurable problem — and the sooner we stop treating metabolic health as a moral scoreboard, the more people will actually get help before their labs turn into a crisis.

Where this leaves me

I started this at 135 kg. By March 2026 I was at 95 kg — forty kilograms, in about seven months. I've held there since. If anything, the holding is the part I'm more quietly proud of; losing weight on a drug is one thing, staying put is another.

But the weight is the legible number, not the important one. The important ones are the labs that started all this, and every one of them has moved back into a range my doctor is comfortable with. Those numbers are between me and him. What I'll say publicly is that the risky zone he described in May 2025 is no longer where I live, and that is the entire point.

A smaller change caught me off guard, and I mention it because nobody warns you about it. I used to barely shop for clothes — the things I actually liked were never available in my size in a normal store, so I stopped looking. Now they are. It's a trivial thing next to a lab report, and yet the first time I walked out of a shop with something I'd genuinely chosen rather than settled for, it landed harder than any number on the scale.

If I zoom out, the scale was never the goal — it was just the most honest instrument I had, the one that gave me a daily reading when the labs only came around every few months. The real question was always the one my endocrinologist put to me at the start: were my markers going to keep drifting into the danger zone, or not. A year in, the answer is different, and that's the only result I actually care about.

The honest open question — the one nobody writing about this seems willing to sit with — is is this forever. I don't know. I'm four months into holding, not four years. I don't know yet what happens to the food noise if I ever come off, and I'm not going to pretend I've solved a problem I'm still inside of. What I can tell you is that I'm treating it as open-ended rather than betting on an exit, because the version of me that assumed this was a temporary fix is the version that ended up at 135 kg. If maintenance is the price of staying out of the danger zone, that's a price I understand.

The drug earned its place in that. But it was a tool I operated, not a miracle I received. Worth being precise about the difference.

One person deserves more than a footnote here: Dr. Anurag Lila, my endocrinologist at Dr. L. H. Hiranandani Hospital in Powai. He was the one who refused to let me tune out the numbers, and he's since done the same for several people in my family and among my friends — some of whom came to him after watching this happen to me. Watching them get the same honest reading and the same results has been one of the better side effects of the whole year. Find a doctor who will be blunt with you about your labs. It changes everything downstream.
