The theory of “Calories In, Calories Out” really doesn’t work, primarily because we are not machines with a single fuel source and only one way to store and burn fuel. Our bodies are hormonal and those hormones have a tremendous effect on how we burn and store fuel, both glycogen and fat.
Intermittent fasting provides a longer fasted period during the day during which your body has to rely more on fat stores. This may take a couple weeks to get used to at first, but your body will get more efficient at releasing and using stored fat for fuel and will supply your energy needs until your first meal, usually around lunch time. Ideally you want to have about a 16 hour window from the last time you ate the day before until your first meal the next day.
We hear a lot about things we can do to boost our metabolism but how much of an impact do those actions really make? The majority of our metabolic rate comes from organ function and supporting our tissues. About 10% comes from the digestion of food (TEF) called the Thermic Effect of Food and 10-20% from our activity, depending on how active we are.
