There is not much of a difference between being knocked out of Ketosis and producing such a low level of them that you aren’t losing weight.
For all intents and purposes, if you aren’t losing weight, it doesn’t matter if you have a negotiable amount of ketones.
Insulin is the main driver of Obesity. If you see a Glucose Reading that is spiked up to 100 you know INSULIN is on board and your body is burning Glucose – not Fat-- and perhaps, even storing fat. (whether it’s storing fat depends on the state of your particular metabolism)
If you get your Glucose low enough, i.e., low 80’s – 70’s you’re burnt through your Glycogen and your body has switched to burning Fat.
Can’t burn Glucose and Fat at the same time. It’s one or the other.
Just being technically in Ketosis is not good enough if your body isn’t responding by losing weight. You’re got to find out what is preventing you from producing enough Ketones for your body to respond by burning fat.
It’s possible to be deeply in Ketosis and not drop pounds every day or every week, but the person who was asking the question said she was not losing any weight and hadn’t for a long time. That means there’s insulin on board, which in turn is knocking down her level of Ketones to such a low level as to prevent the burning of fat.
There are more than 3 episodes on the Obesity Code Podcast where someone had lost a lot of weight, but was stalling out at the last lap and Megan had to find out what was in their diet that was causing the stall.
It was always something teeny, seemingly harmless but their body was stalling. Also, I heard Megan on a separate video on the IDM website talk about sweeteners often getting in the way of weight loss.
