My First Week on Mounjaro: A Jab Well Done

Well, I’ve officially completed my first week on Mounjaro and I feel… pretty good, actually. Like, surprisingly good. Given how nervous I was about side effects, I half expected to be writing this from my sickbed with a hot water bottle and a bucket by my side, but here we are, and I’m still standing (well, sitting, but you get the point).

The nausea I mentioned after my very first jab subsided after a few days, and though it did make a dramatic return after jab number two, it’s definitely milder this time. A little queasy here and there, but nothing that’s stopped me from going about my day. I’ve got a bit of a sore leg this morning, thanks to the jab itself, but honestly, if you’re willingly stabbing yourself with a needle once a week, you can’t really complain about a little tenderness. It’s all part of the fun, right?

The Hunger Games (Except I Didn’t Kill Anyone, Thankfully!)

Let’s talk about appetite, or more accurately, the complete lack of it. I’ve noticed that I’m eating much smaller portions than I was before. Meals that used to be easy are now leaving me full halfway through, which is both a novelty and a blessing. There’s something quite satisfying about looking at a half-eaten plate and thinking, “Actually, I’m done,” instead of convincing myself to finish it because it’s there.

The end result? A little victory on the scales, but more on that later (because suspense is fun).

The Mid-Afternoon Slump

The only thing that’s really tested me this week is the tiredness. Around 3pm, my body likes to remind me that it’s surviving on fewer calories and demands an immediate nap, coffee, or both. Early in the week, that slump hit hard, we’re talking eyes-glazing-over-during-an-email hard, but the past few days, it’s eased off a bit. I think my body’s starting to get used to this new rhythm.

And yes, coffee absolutely helps. In fact, coffee might just be the unsung hero of my Mounjaro journey so far.

Back to Slimming World (and Back Among Friendly Faces)

This week also marked my glorious return to Slimming World. I dusted off my membership card and nervously reappeared at my local group, where I was welcomed back with open arms and a surprisingly loud cheer from Lesley, my consultant.

Lesley completely understood why I’d been away. Life happens, bodies do what they do, and sometimes you just need to reset. It was lovely to be back in that supportive space, surrounded by friendly faces (all new ones this time) who were encouraging and chatty from the start.

There’s something genuinely uplifting about those meetings. For one thing, they get me out of the house and talking to actual humans, which is never a bad thing. For another, I get to swap recipe ideas and hear what’s working for other people, from slow-cooker hacks to inventive ways to make chicken interesting again. Oh, and sometimes there’s food to sample. Free snacks are always a win in my book.

A Burger-Based Betrayal

Now, it wouldn’t be a proper week-one diary without a bit of drama, would it? Enter my first diet-related disappointment.

My husband and his colleagues invited me to a dinner and pub quiz night, which sounded delightful until I saw the menu. Big, greasy burgers. Chips. Not a single salad in sight. Not even one sad leaf pretending to be a garnish.

After some soul-searching (and a few choice words muttered under my breath), I decided to skip the meal portion of the evening. I’ll still join them later for the quiz, but I’ll be doing so on a virtuous stomach full of lettuce and dignity.

I’m sure I’ll have just as much fun eating my salad alone at home as they will have scoffing down burgers and pints. No, I’m not crying, you are.

The Moment of Truth

Right, let’s talk numbers. You’ve patiently read through my ramblings and now want to know how much weight I’ve actually lost this week.

Drum roll, please.

Four pounds.

Yep, four whole pounds gone in the first week. Or, if you prefer the metric system, that’s about 1.8kg. Honestly, I’m chuffed to bits. It might not sound huge to some, but when you’re in it for the long haul, every pound feels like progress. I’ve got a total goal of around 58lbs, so this is an encouraging start.

I’m sleeping better, I’m not feeling quite as sluggish, and those pesky side effects from Jaro (yes, we’re on nickname terms now) seem to be slowly fading into the background.

Looking Ahead: Cautious Optimism and Two Dinner Dates

A big thumbs up

As I head into week two, I’m feeling cautiously optimistic, emphasis on cautiously. I’ve got not one but two meals out over the weekend, which will be my first real test of willpower. My plan is to stick to the plan as best I can, make sensible choices, watch portion sizes, and maybe, just maybe, allow myself a cheeky glass of wine.

Because here’s the thing: this isn’t about perfection. It’s about balance. Life doesn’t stop because you’re on a weight loss journey, and there’s no medal for white-knuckling your way through every meal. If I can enjoy a bit of family time, make mostly good choices, and still see a little progress on the scales next week, that’s a big win in my book.

A Few Lessons from Week One

If there’s anything I’ve learned so far, it’s this:

  • Listen to your body. If you’re tired, rest. If you’re full, stop. It sounds simple, but after years of ignoring those cues, it’s oddly refreshing.
  • Plan ahead. Knowing what and when you’re going to eat makes everything easier, especially when you’re not as hungry and might otherwise forget to eat altogether (yes, really).
  • Don’t isolate yourself. Support makes a huge difference. Whether it’s Slimming World, friends, or a good old-fashioned WhatsApp group chat, staying connected keeps you accountable and encouraged.
  • Celebrate the small wins. Four pounds, fewer cravings, feeling better, all worth celebrating.

Final Thoughts: Still Standing, Still Smiling

So, that’s my first week on Mounjaro done and dusted. I’ve learned that Mounjaro isn’t a magic wand, but it is a tool, and one that’s helping me build better habits. I’ve also learned that I can survive social temptation, even if I do occasionally sulk over a missed burger.

Here’s to week two: more progress, fewer naps, and maybe even a smaller pair of jeans.

Stay tuned, because the next instalment of my Mounjaro diaries is bound to be full of more discoveries, fewer grumbles, and hopefully, a few more pounds gone.
