There are three kinds of ketones, and the urine is only tested for acetoacetate. As you switch to the more efficient fat-burning process, you convert that acetoacetate to beta-hydroxybutyrate. So, yes, your test can show negative or zero ketones. Look at other factors. Are you losing weight? Are you feeling good? If you’re doing 20 grams net carbs a day or less, you’re going to be in ketosis, no matter what.
A standard ketogenic diet consists of a split of around 30 per cent protein, 60 per cent fats and 10 per cent carbohydrates. Experts advise that you should eat no more than 50g of net carbs a day for the body to stay in a ketogenic state. 50g of carbs is equivalent to one cup of oats, one medium sweet potato, one cup cooked brown rice or one slice rye bread - in other words, not much.
You’ve probably heard about the low carb, high fat diet that’s so popular among actors and models, and with good reason: low carb diets offer proper nourishment with whole foods, while keeping your body burning fat for fuel. This is a great way to be, as it makes fat loss largely effortless! But where does this “ketogenic” word fit into the picture?
Meat is fair game when you’re following the keto diet, which is why Griffin is a fan of putting together a plate of charcuterie when you’re in the mood for a snack. This doesn’t need to be one of those fancy displays you’d find at a restaurant — you can keep it simple and arrange whatever cured meats you have on hand. (Psst: This one makes a great party appetizer, too!)
We understand that you may not have time to track all your macros, which is why we include the macros with each keto recipe. However, try grabbing a handful of almonds for a keto snack and realizing even a big handful is over a "serving size" and greater than 200 calories. If you are using the keto diet for weight loss, this may not fit into your macros of 1200-1500 calories per day.
Our bodies are incredibly adaptive to what you put into it – when you overload it with fats and take away carbohydrates, it will begin to burn ketones as the primary energy source. Optimal ketone levels offer many health, weight loss, physical and mental performance benefits.1There are scientifically-backed studies that show the advantage of a low-carb, ketogenic diet over a low-fat diet. One meta-analysis of low-carbohydrate diets showed a large advantage in weight loss. The New England Journal of Medicine study resulted in almost double the weight loss in a long-term study on ketone inducing diets.
