The broken down fats in the liver generate Ketones, pushing your body into the state of Ketosis, fueling your body with fat. There was a small decrease in one study with substantial weight loss and a slight increase in one study with slight weight loss. No notable difference between groups when calories are matched, and a reduction in two uncontrolled trials with weight loss, as could be expected.
Urine sticks will always be the cheapest and easiest way to measure ketosis. For beginners, this should cover everything you need – there is no point in getting more complex blood strips so early on when you are still trying to understand the nuances of a ketogenic diet. So, if you’re committed to a low-carb diet to lose weight, be patient and allow your body to adjust to its new fuel source. Be aware that some chewing gums and mints contain a small amount of carbohydrates.
