Kourtney Kardashian Shares Finger Prick Photo, Proving She’s in Ketosis: ‘May the Fat Burning Begin’

usmagazine.com:

Kourtney Kardashian shared a photo of herself pricking her finger, but it’s all a part of her most recent stint on the keto diet.“Morning keytone [sic] and glucose level check …,” the Keeping Up With the Kardashians star, 41, wrote in an Instagram Story of the blood test, which she shared on Wednesday, July 1. “… and after two days of eating ‘keto’ I am in ketosis (.5).”The goal of the strict eating regimen, which forbids foods such as grains, beans and juice, is to enter a state of ketosis through fat metabolism.

Once in a ketogenic state, the body then primarily uses fat for energy instead of carbohydrates; with low levels of carbohydrate, fats can be converted into ketones to fuel the body.
