Using fat for fuel is often used interchangeably with using ketones, but this is not exactly the same thing. Even when you are eating a lot of carbs in your diet, you can still use fat (and do quite frequently!) as a source of energy without needing to go into ketosis. The type of fat you are using for this is primarily coming from stored fat (fatty acids). Stored fat is actually a preferred source of energy in-between meals, during rest, and after long duration exercise. Your body has an almost unlimited capacity to store and use fat compared to carbs, as we’ve seen with the obesity epidemic. And using fat gives you twice as much energy for the same amount of work (one gram of fat is 9 calories whether you eat it or burn it, compared to carbs that provide only 4 calorie a gram) – making it a desirable source of fuel.

A simple standby, but one that ketoers adore. 2 or 3 fried eggs and some bacon might not sound like much, but it’s full of protein that will keep you full and energized all morning. Take the opportunity on the weekend to lay your bacon strips on a single cookie sheet and bake in the oven for 20 minutes at 400 degrees. The result is the best bacon you’ve ever had, in a big batch, with no sitting over a popping, hissing frying pan.
But the process of using fat for fuel is slow and requires oxygen and some glucose to begin with - making it not a very efficient source of fuel over long periods of time. This is especially true during higher levels of energy output when oxygen is limited (basically any high intensity workout/movement). In addition, it is not directly able to supply your brain with adequate fuel since fatty acids cannot cross the blood-brain barrier. So when carbs are absent, your body is forced to find a way to survive off fat that meets your needs. It does this by using ketones.

Glucose is important for more than just quick energy. It is also the only source of fuel that is able to cross the blood-brain barrier. In other words, your brain loves carbs. This is another reason why your body prefers this macro for energy. Because glucose is the type of sugar found in your blood - it is clearly important for maintaining blood sugar control, and pretty impossible to survive without it.
A: The amount of weight you lose is entirely dependent on you. Obviously adding exercise to your regimen will speed up your weight loss. Cutting out things that are common “stall” causes is also a good thing. Artificial sweeteners, dairy, wheat products and by-products (wheat gluten, wheat flours, and anything with an identifiable wheat product in it).

You may also have to moderate protein intake somewhat, as high protein intake (greater than 2.0g/kg/d) may make it more difficult to maintain ketosis. However, eating too little protein may also present health issues such as poor muscle development, increased hunger, and lack of essential amino acids. That is why we recommend a moderate level of protein intake, defined as 1.2-1.7g/kg/d. See our protein guide.
^ Ketogenic "eggnog" is used during induction and is a drink with the required ketogenic ratio. For example, a 4:1 ratio eggnog would contain 60 g of 36% heavy whipping cream, 25 g pasteurised raw egg, saccharin and vanilla flavour. This contains 245 kcal (1,025 kJ), 4 g protein, 2 g carbohydrate and 24 g fat (24:6 = 4:1). The eggnog may also be cooked to make a custard, or frozen to make ice cream.
