I’ve been intermittent fasting for a while and was feeling pretty good, but 2 weeks ago I started keto and it’s a bit rocky. 2 days in I felt about the same as with IF, but I noticed my blood ketones had only made it up to about 0.3 even 36 hours in. As time went on, when eating I couldn’t get satiated, and kept eating and eating more of the keto food I’d made (eggs, avocado, bacon, cheese, mayonnaise in that first week). It was like my stomach had doubled in size all of a sudden.
I started running into problems with insomnia and anxiety and fatigue about 4 days in. By this time my ketones were finally up around 1.0. On the fifth night after laying awake restless and anxious until 2 in the morning I checked my blood glucose and a red light on my meter lit up saying it was low. It was at 3.6 m/mol. Not wanting to quit I toughed it out and managed to get to sleep an hour later.
The next day I checked my ketones about 3 hours after I woke up (but hadn’t eaten) and they were down to 0.7, and my glucose slightly higher at 3.8 (dawn affect maybe?)
Fast forward through another day of suffering and then I ordered a keto crust pizza from pizza 73 and ate the whole thing. I knew there were some extra carbs in the onions and green peppers but figured it would be in the allowable range. I felt so much better, and to my surprise when I checked my readings 2 hours later both my ketones AND glucose were up. This was the highest I’d seen my ketones (1.4) and my glucose was 4.2 — so still nice and low blood sugar but no more feeling crappy and no more low glucose alarm on the meter.
I had to turn the thermostat in the house down to 17 Celsius, and even then was too hot in bed without a fan on, which I’m sure must have been my metabolism kicking on.
I suppose I should mention that I’m a 35 year old male that’s a very muscular 260 pounds. I probably have about 30 to 40 pounds of fat to lose before it won’t be apparent that I’m overweight when you see me in a t shirt.
Anyways, it’s probably fair to say that my carbs were way below the allowable amount for those first 5 days, but it seems like my metabolism just shut down instead of making more ketones.
Is making sure I get a bit more carbs what I need to be doing? I’m frustrated at my low ketone levels, but even more so at the fact that my metabolism seems to be shutting down amidst shoveling down huge fatty meals without ever feeling satiated. FWIW I should also point out that I put on 2 pounds during that time, but managed to shed it within a day or two of my glorious keto pizza feast.
Any insight and tips would be super helpful!
