Meal replacement shakes and WLI?

22 replies

Is anyone using milkshakes (eg Fast Diet 800, which are pretty low in sugar compared to some) alongside weight loss injections or pills?

Thinking of using them for breakfast and lunch but then having a small evening meal. Anyone have any experience?

I’ve been having the Slimfast protein shakes. Strawberry flavour, one for breakfast and one for lunch, then a small dinner. 2 apples per day for snacks. Seem to be losing ok.

The only issue with this is, it’s not a sustainable diet long term.

I bought the Purition starter pack , had difficulty telling one flavour from another.

Their “natural and subtle” is my “bland and tasteless”.

After reading lots on here I decided that the main thing I wanted while on WLI was to re-educate myself and create new food habits. So I've changed what I eat, upped protein and dropped carbs. It's worked well for me and hopefully means that I won't gain weight long term.

I personally wouldn't go for meal replacement because I wouldn't want to do that long term.

I have a ufit iced latte for breakfast most days. I do try and eat food rather than too many shakes etc. But if I know I'm likely to miss a meal or have a high suppression day (doesnt happen so much now) then I'll have a ready made Yfood meal replacement shake either the chocolate or cold brew flavours. They're more balanced in terms of nutrition.

Thanks everyone. I have tried both MJ and Wegovy last year (but had terrible vomiting and diarrhoea). My diet wasn't great to be honest and I'm just wondering if shakes might help me stay on the straight and narrow.

I know it'll only be short term, but i just need a bit of a kick start

Good luck, @BerfyTigot - I remember you from the May 2025 WLi threads and how poorly they made you feel.
But you nevertheless gave it your very best shot.
IMHO, anything that gives us a kick start is worth a try, what works for one person may not work for another.
Shakes don’t have to be only a short term thing.
I love the convenience of them, it was just the brand I mentioned above that I found unpalatable - my cousin loves it, and has done very well .
Onwards and downwards, Berfy ! 🤞

New You Plan meal replacement sachets are quite tasty, but again, not sustainable long term. But it does ensure you get all the nutrients you need.

If you have an addiction to poor food choices then UPF shakes will keep it ticking over until you eat again. If you can change your habits you can keep the weight off. My brother used bone broth for one meal a day and the other was a very high fibre salad with lean protein. He bought the broth in single serve packets and used bagged salad and then cooked 4chicken breasts or did eggs to slice over it. Not too much work. He lost 12 stone and has kept it off because his cravings have stayed away. Good luck OP. It's so hard.

BerfyTigot · 01/07/2026 08:51

@ElsieJay Hi again! I remember you too! I've got everything crossed for this time. Been taking Symprove to improve my gut health and reduced ultra-processed foods.

How are you doing?

BerfyTigot · 01/07/2026 08:53

@faithfultoGeorgeMichael 12 stone is amazing! Yes, I'm a bit worried about upf. But shakes worked for me in my 20's.

Still waiting for the pills to be available...

I'm not sure the pills are going to make this easier or cheaper, sadly.

Sounds like the OP has ditched the WLI, but I’d caution against taking meal replacement drinks if you’re doing WLI at the same time as you won’t get near enough fibre in your diet that way and then you risk serious constipation issues, which can be very painful and cause other complications.

takeharry · 02/07/2026 11:23

I don't really see the point.

WLI should support a healthy diet, when used correctly they are the most incredible tool. It seems crazy to me not to use them to the best of their ability.

@BerfyTigot - sorry for delayed response, am on holiday at present .
Eating very badly, but have two pens in fridge awaiting my return !
Very best wishes to you also.

KeptWomanSummer · 08/07/2026 15:04

I agree with everyone else that we need to reeducate ourselves with the meals etc.

So I wouldn’t go for also a fad diet alongside the MJ.

However - I do keep some of the extra protein yogurts from Aldi in my fridge. Purely because if there are days I am having really strong appetite suppression I still want to make sure I’m getting protein and I’ve found these the easiest way for me to do so.

So if slim fast meant you’re getting protein and vitamins when you otherwise wouldn’t then I’d maybe see a benefit but not instead of actual food if you can stomach it.

BerfyTigot · 08/07/2026 17:24

Thanks for all the replies. I've started on Mounjaro today.

Been eating really healthily for the past few days and feeling pretty good.

I'm going to use shakes on the 2 days a week when I'm travelling and really struggle with snacking. And then I'll just see how it goes.

@ElsieJay enjoy your holiday 😁

UnimaginableWindBird · 08/07/2026 20:06

I do, but not all the time. For me, it's part of a long term sustainable way of eating. I mostly eat normal food, but if I run out of time to prepare lunch, if I wake up hungry and want a quick breakfast to keep me fuelled for an early morning weights session before work, if I can't find anything with enough protein and fibre, I'll grab some Huel when that's the best real world option at the time. I have ADHD, so having a back up plan for when I forget something or mismanage my time is the only way I every get stuff done.

So I started yesterday lunchtime and am genuinely not hungry today. It might be the heat though.

I know i need to have something, so I'm sipping a Fast 800 shake (made with skimmed milk). Not intending to do many of them though, just while I'm starting and on days that I'm travelling.
