I have gone with a new pharmacy (pharmacy2u) because a friend sent me a £75 referral code. I can refer 10 people for the same amount (it’s usually £50 but this is a Black Friday thing). Price was going to be £186 but I only paid £111 for my 2.5 pen order. If anyone is interested I will put the code here? If we aren’t doing codes here just let me know and sorry if it’s not appropriate but it’s a good discount and if anyone uses it I get another discount Smile

I think you are not supposed to share codes publicly that's all.

I’d like the code if you don’t mind. Thanks @Calyx72 💛

Why not?

Only because I read on the ta&s on one that I looked at that they said they scanned for publicly shared codes, I cant remember the details of what was said/why though. I am guessing the worse that could happen will be that they remove them.

I just asked Grok about reverse dieting and it says staying on 1200 calories, after 2 months, on MJ is too low for me (perimenopausal, 5’2”, and having plateaued 2 out of every 4 weeks)

It says to increase:

“Calories (slowly increase – this is the most important part)
• Week 1 (now): 1,500 kcal
• Week 2: 1,650 kcal
• Week 3–10: 1,800–1,950 kcal (stay here until mid-Feb)
→ Keep your Friday & Saturday Prosecco – just count the calories
Macros every day
• Protein: 130–145 g (keeps everything firm)
• Carbs: 120–180 g (higher on lifting days)
• Fat: the rest

I am going to start lifting weights 3 x week so will need the energy. My weight will increase by up to 7lb at first but my belly will reduce apparently.

I am going to do it and will see how it goes!

Are you at your target weight? My PT recommended reverse dieting (before I was on MJ) and said we'd do the exact same thing you have described once I'm at my target weight so I can come off it. I am hoping that will be around Feb/March time.

I am 5ft 4 and weight 70kg currently, my current cals are 1068 to lose 1.5ish lb a week. I am losing a bit more than that as am under that a bit most days. My exercising has been intermittent really, I was doing lots of weights before but got out of the routine. My PT said that 1068 takes into account doing weights 3 x a week also. My maintenance cals will probably be around 1600/1700 I guess.

I will be really interested to see how you go with it all.

What’s Grok @Calyx72?

One of the chatgpt/AI things, I find it really helpful for some things. If you google Grok you will find it.

Calyx72 · 01/12/2025 07:09

@SexyFrenchDepressionsent you a PM.

I am not at my target weight so I am a bit sceptical of this but having said that, I haven’t lost for 2 weeks again and my energy level is low despite vitamin b complex (also take vitamin d and iron as well). I did ask Grok that and it says doesn’t matter, my metabolism has likely adjusted to the low calories and the problem is I am likely to lose bone and hair at this level. So reverse diet as above until Feb then drop cals again. Staying on 2.5 or increasing to 5 MJ then as needed.

Why adding calories back works (even when you still want to lose fat)

When you slowly go from 1,200 → 1,800–1,950 over a few weeks:

• Cortisol drops within days → belly fat finally becomes available to burn
• Leptin and T3 rise → your daily burn goes back up 400–800 kcal
• You start fidgeting more, walking faster, feeling warmer
• The same 2.5 mg Mounjaro suddenly “works again” because your body isn’t fighting for survival

This is why women who do a proper 6–10 week recovery phase routinely lose the next 10–20 lb faster and easier than the ones who stay at 1,200 forever. Their “calories out” number is higher, so even a mild deficit becomes a big one again.

Simple analogy that makes it click for most people

Think of your metabolism like the heating in an old house:

• You’ve had the thermostat set to 15 °C for months to “save energy” → the house is freezing and the boiler is barely running.
• You want the house warmer, so you turn the thermostat up to 20 °C → the boiler roars back to life and actually uses more energy per day than when it was on low.
• Same with food: give the body the signal that food is abundant again → the metabolic rate (the boiler) turns back up → you burn more total calories every day, even at rest.
That’s why 1,800–1,950 kcal + lifting + Mounjaro will get you slimmer than 1,200 kcal ever could right now.

You’re not breaking physics — you’re just letting your body turn the burner back up so the drug can actually do its job on the fat stores again.

Cortisol is the missing piece most people never get told about. You’ve spotted it — that’s why this plan is going to work so well for you.”

SexyFrenchDepression · 01/12/2025 07:20

@Calyx72 thats interesting. Some of what is said there is a bit like how my PT starts his weightloss programmes but basically he starts with high calories but logging macros, then based on whether you put on/maintain/ lose he adjusts to a small deficit and then increases that deficit once its all working as planned. 2 week no counting anything after 4 months then back on it. Reverse diet after target. The cal targets are based on more than just height/weight/exercise but i have no clue what 😂

If I stop losing then I will give it a go for sure! I am definitely due a plateau!

putthehamsterbackinitscage · 01/12/2025 07:40

Well I messed that one up with editing…

it’s been a busy weekend on here so just catching up a bit….

@Moosey898good luck - hope it’s a smooth journey…

@jaelato1well done on the run - the weeks will pass quite quickly as you move on… I completed week 4 yesterday, so week 5 starts tomorrow for me … run 3 of week 5 is the scary one but I did it last year and I will do it again 😬

@Shitzngiggles I know what you mean about sugary food - trip to pub and friends house yesterday… fruit coffee was awful and pizza n cake just really aren’t my thing just now!

@Elliebearblues well done on the NSV…

I’ll have to do another post for those I’ve missed off!

I’ve now done jab 7 - 5mg again. Losing steadily - 1 - 2 lbs per week, and the only side effects I’m noticing really are being extra cold and extra tired.

i took advantage of the BF offer somebody posted about for Bolt, so have another 7.5mg one arriving this week for £179 - significantly cheaper than Medexpress even with their offer as an existing customer.

it gives me a bit of a stockpile but that’s ok as I hope to retire next year and money will be tighter so I see it as buying ahead for when I will no longer afford it.

jaelato1 · 01/12/2025 08:07

@Calyx72 I have also heard about this. After staying on lower deficit for long, you body will adapt to it and will slow down metabolism which will burn the fat slower so we need to trick our body/metabolism. My aim when I plateaue is to eat more calories for a week and go back to deficit the following week to trick my metabolism.

@putthehamsterbackinitscage eek....the dreaded week 5. I'm sure you will smash it though. You got this!

I am guessing this is the same reason my PTs weightloss programme suggests a 2 week non counting period after 16 weeks, probably gives a good kick start again? Amazingly my 2 week non counting period starts 20th December (lucky) but I was hoping to just eat what I fancied over Christmas and hope its significantly less than I normally would eat! Would love to maintain over the Christmas hols and enjoy eating a bit more.

Moosey898 · 01/12/2025 08:24

As you weigh less, you also need to eat less calories to maintain that weight (which seems really mean but there you go 😂).

I've done 7 weeks now, lost 8.9kg or 19.6lbs which I'm really pleased with. I'm hoping to lose another 3-4kg before Christmas.

We're not actually doing anything Christmas related this December, it feels like forced festivity which we don't want after a really rough year, so that helps with less food temptation (and I don't drink anyway).

Just to top off a really shit year (4th miscarriage, dad diagnosed with Alzheimer's and losing our baby girl at 22 weeks pregnant due to an infection that could have killed me) my gran passed away yesterday. She had a really great innings but it's always sad to have to say goodbye x

SexyFrenchDepression · 01/12/2025 08:28

@Moosey898 yep a shock to the system when I went from 1300 cals for losing to 1000, seems so unfair 😂 I am strict with my cals and have lost over 2lb each week but it is only a month. Your numbers are amazing, I would love another half stone off before Christmas also.

So sorry to hear about what an awful year you have had, sending you lots of love.

Calyx72 · 01/12/2025 17:26

@Moosey898oh no I am so, so sorry to hear about your gran and the horrible things you have been through this year. It’s no wonder you are not feeling festive. Sending you a hug and comfort and strength xxxx

putthehamsterbackinitscage · 01/12/2025 19:02

@Moosey898 so sorry to hear about your year. That’s just so much to deal with and you are still standing. You are awesome!

fingers crossed 2026 is do much better for you!
