Use our keto calculator to calculate the exact macros you should be eating. Remember, substituting more fat for carbs or protein is almost always ok. In fact, if you're worried about losing muscle mass because of decreased protein consumption, you may not need to worry. There has been evidence that while in a state of ketosis your body actually maintains protein better than in a standard diet.
Basically, the role of exogenous ketones is to boost the amount of ketones in your body. These products do work wonders if, after a long time on a keto diet, you don't feel energized or generally don't feel like you are at your best. Ultimately deciding to take exogenous ketones or not comes down to how you feel on your keto diet and trying to find a product with the highest possible quality.
Before we discuss how to measure ketone levels, let's set some guidelines for optimal ketone levels. Nutritional ketosis is detected when levels begin to read at 0.5 mmol/L of ketones in the blood, but your optimal ketone level will depend on your personal goals. For instance, if your goal is to lose weight, your target ketone level will be lower than someone who wants to improve mental performance. The following table provides some general guidelines based on your goal.
On the other hand, the types of foods you'll avoid eating on the keto, low-carb diet are likely the same ones you are, or previously were, accustomed to getting lots of your daily calories from before starting this way of eating. This includes items like fruit, processed foods or drinks high in sugar, those made with any grains or white/wheat flour, conventional dairy products, desserts, and many other high-carb foods (especially those that are sources of œempty calories).
I've always heard that the brain functions well on ketones. Gluconeogenisis typically reduces ketosis, though as well? This is the first time I've heard anyone say the brain can't use anything but glucose. I know there's *preferred* sources of fuel over others, but I was also fairly certain other sources were fine.. or humans might be in a bit of trouble.
