Flip that metabolic switch – and now you're burning lots of fat . . .

AFTER a few days on the Fast 800 Keto and excess body fat is burned as fuel, fatty acids are released from your fat stores and converted into chemicals called ketone bodies which can be used by most cells in the body and brain.

My wife can always tell when I’ve ‘flipped the metabolic switch’ and gone into ketosis because my breath starts to smell sweet – like nail polish remover.

It’s an exciting moment, because it means the diet is working and I am burning lots of fat!

A more scientific way to check if you are in ketosis is to use keto strips.

Available cheaply from pharmacies or online, these thin strips of plastic have an active agent on one end which you dip into your urine stream. The agent changes colour if it detects ketones. It’s VERY motivating to see the strip turn red and a surprisingly useful deterrent if you are tempted by a biscuit!

The strips were originally created for people with type 1 diabetes, to detect a dangerous condition called diabetic ketoacidosis, but this should not happen on a keto diet – you are merely looking for mild changes.
