Please help - I seem to be one of the few people who are attempting to follow a ketogenic diet without needing to lose weight and am struggling to stay in ketosis due to it being imperitive that I maintain enough calories (so no OMAD or fasting for me at the moment, however I only eat fat or meat juices for breakfast and don’t eat a substantial amount of protein until lunchtime). I am wearing a Continuous Keto Monitor at the moment, as well as a CGK to check what is going on. I am eating almost zero carbs (carnivore on a daily basis with a strictly keto meal when eating out with friends in order to look normal!). I cannot eat dairy - not even goat ghee. But despite my glucose being consistently low (4-5 millimole) and eating as much fat as I can (so far I haven’t reached my upper limit for tolerating fat), I can’t stay in ketosis for more than a few hours at a time. It never gets above 1.8 and usually hovers low at between 0.5 - 1 millimoles, and will often flat line for most of the day or most of a night at 0.1, and seems random when it arrives (though it is mostly after midday) and any meal containing enough meat to stop me feeling hungry, seems to put an end to ketosis. I am doing this for Hashimotos and mental health purposes. Depression in my case, but two of my siblings have severe bi-polar, OCD and Asperges, and so I was hoping to role model this to encourage them to do it too.
I started to go low carb in January and went ‘keto’ level low carb by April. I was relying heavily on dairy including butter and cream for the fat and calories. I then removed dairy as an experiment due to advice re Hashimotos triggers. I discovered that dairy was the cause of several physical health conditions which cleared up miraculously within a week and some of the mental health problems (agitation, rage, irritability). However, within a fortnight I had dropped 22 pounds (10 kilos) which seems impossible, but definitely happened. Since then I have been underweight and look like a skeleton with some muscles and ligaments attached. It ain’t pretty! I am desperate to gain weight, but haven’t been able to since April. In April I tested my ketones with urine strips for a month and I was showing definite ketone production, particularly in the afternoons and evening. I then gradually reduced my diet down to carnivore (for allergen/hashimotos triggers reasons) and spent the summer at sea on a boat with no access to any testing, and probably not enough access to calories as we don’t have a fridge on the boat so keeping enough meat can be a problem. (I had to make friends with tinned sardines). I was also dealing with my husband being angry at me for doing this and haranguing me at every meal. Thankfully he is now resigned to it. I have now doubled my meat intake and my fat intake and I think I am now hitting my protein target as recommended for my ‘ideal’ weight. I am usually around 70% fat and am near zero carbs, but find it hard to get enough calories to gain weight. I sometimes add olive oil, avocados and coconut milk/oil for the easy fat boost so am open to non-strict carnivore suggestions.
I am sorry this is a long post, but I needed to write enough for you to understand my situation.
I would welcome any advice on how to trigger and maintain ketosis for sustained periods of time, how to get the ketones higher, and how to get enough calories and nutrients into me to maintain / gain weight.
The good news is that whenever I am in ketosis, I can tell instantly - everything goes bright, my brain fog clears, I suddenly have motivation and can concentrate well and all my joint pain disappears. When I drop out of it, I can also tell instantly - I become heavy, sleepy, confused and unable to start new tasks without massive willpower… So I’d really like to master staying in at least low levels of ketosis for the majority of the time.
Thanks in advance for any advice you can offer me!

) and I’ve struggled a bit, myself. The most noticeable being my regular experience with Seasonal Affective Disorder, which I would go through right about this time of year every year. However, in the last 10 years, and especially the last 6 with essentially no carbs in my diet to speak of, I haven’t dealt with it in the slightest.
