Keto and Mounjaro

Hi, Is anyone doing a Keto fasting diet and taking Mounjaro?

I did when I was on mj. Very effecting imo. I'm just back to keto now to get off the last bits. I couldn't afford the jabs anymore.

By default, as I aim for a calorie deficit, and need to ensure I eat enough protein To protect my muscle. So by default by carb intake is low. Not sure it’s keto but it’s low carb,

Yes, me😊 I've been scouring the chat to see if there is a thread on Keto and MJ, so it nice to see one!

I find it is easy - keto being an appetite suppressant in it's own right - it seems to go hand in hand with MJ; enabling intermittent fasting too.

Keto makes me feel very good emotionally and mentally and I'd like to think MJ has allowed me the opportunity to stay focussed (very motivating getting progressive weight loss, for example).

While I have lost weight before on keto, it never seems to last but I feel this time is different and am motivated and enthusiastic that I can do this for the long haul (I have a lot to lose) and importantly, adopt the way of eating in the long term when I no longer take MJ.

Hope that helps.

I am following a keto diet roughly.

I find it the most effective way to lose weight, and because I can't eat much on Mounjaro it make sense to prioritise protein and fibre.

Tootyfilou · 02/02/2025 22:50

Great to see others doing this! I have done Keto a few times with good results, but I can never sustain it long enough to hit my goal. I love Keto, think the science behind intermittent fasting is compelling and it makes me feel great.

I am hoping that combining it with MJ will be the key to success 😀

I don't do intermittent fasting as it made me miserable and actually fatter. That said, on Mounjaro I often only eat twice a day (with my first meal around lunchtime) so I guess it works out the same albeit without the intention!

TheChosenTwo · 03/02/2025 19:21

I only eat 2 meals a day on MJ and no snacks, my lunch is always carb free but depending on what’s for dinner there may or may not be carbs. I’m reducing them for sure, but mostly because I was in a terrible habit of eating bacon sandwiches mid morning and then bread later on in the afternoon with a snack plate of some kind and then potatoes/rice/pasta with more bloody bread for dinner.

How are you all getting on with keto and MJ? I have finally reached 3 stone down! (started September), so weight loss nice and steady.

I still have a long way to go, but motivation is high and keto makes me feel so much better emotionally, so it is win win.

I think the combo of MJ, keto and, by default really, intermittent fasting, is really excellent (for me anyway).

Would be good to keep this thread going, as while I get loads of support on mumsnet (the key one being the 5 stone+ threads), it would be great to share hints and tips with folk that are actually doing keto.

Hi
I had lots of success on lchf diet in the past but did gind it hard to maintain after 6 months or so... started missing bread fruit etc. I was under 30g carbs most days which is v low.

How does mj work with the high fat aspect of keto?

Any digestive side effects?

NewbieMJ · 15/02/2025 13:11

@Goinghome24 I know what you mean. Previously, I have bought keto friendly breads, but they cost a fortune and it really isn't sustainable long term. On MJ, I don't crave bread, which is an eye opener, as it is my number one favourite food of all time - so that is a relief.

I occasionally allow myself a handful of frozen blueberries for a fruit fix, or raspberries (lovely with double cream of greek yoghurt) with cinnamon sprinkled on top (I add it to my daily carb count).

I have found the fats to be no problem whatsoever re digestive issues. I introduced a probiotic early on, so I think that helped my gut adjust.

I find keto difficult to maintain in the long term - mainly due to it being very difficult to eat out/grab a quick supermarket lunch kind of thing. It takes a lot of work, cooking from scratch, etc. On MJ it is easier, as the weight loss (which is more regular and consistent, for me anyway) is a huge motivation and keeps me on track.

I try to use damage limitation when I eat out and choose the keto-friendly options when I need to grab something quick (cooked chicken, prawns, boiled eggs). Apart from M&S and sometimes the Co-op, the other supermarkets salads are full of carbs (pasta, rice, grains or potatoes). Very frustrating.

Anyway, my main aim is to get the weight off, but I know I also need to think about a sustainable way of eating in the long term, and keto seems the closest thing that I would be able to adopt when I am off weight loss injections. I am not really a great believer in calorie deficits, etc which I know goes against the grain on Mumsnet. For me, it is all about altering your set point, tackling insulin resistance and incorporating fasting for health.

Are you still doing keto and IF?

NewbieMJ · 22/09/2025 19:26

Yes, I am 😊Loving it. Can't imagine eating any other way now. Almost 6 stone down.

Tootyfilou · 06/10/2025 21:34

@NewbieMJ That is amazing, congratulations. I have lost five stone... another two to go for my goal, I never thought in a million years that I could achieve this. It is a dream come true.

It certainly is, I feel the same. Reached 6 stone yesterday and I had tears!

Congratulations! I have 2 stone to go too. Are you doing keto? I love it and can't imagine any other way of eating now.

Tootyfilou · 06/10/2025 22:37

@NewbieMJ Yes doing keto, its amazing. Huge congratulations x

I don’t want actually to be in ketosis or I will struggle to run but I eat just enough carbs (circa 80-100g a day) to ensure I am not in ketosis.

NewbieMJ · 10/10/2025 18:57

@MeridaBrave That is interesting that you lack energy for running while in ketosis. Usually it gives you tonnes of energy (and I thought it was the body's preferred energy source), but I am no expert. I think the thing with MJ is that it is a very personal journey and it needs to click and work for you. How are you getting on with low carbing?

All welcome here - keto, low carbing... lt'd great to get others on board and get the thread going for fellow low-carbers.

It’s totally normal to not be able to run in ketosis. That’s because when you are running you need energy quickly, and the only real source of fast energy is muscle glycogen which by definition has run out as you are in ketosis.

Low carb works well for me generally under 100g a day.
