Ketosis is a state which the body enters when you consume less glucose (which you get from carbohydrates) than the body needs. The amount of carbohydrates to avoid this state is unclear, but most people suggest that it is 100g or 50g.
But Ketosis is not dangerous because the body is fully capable of producing glucose on it's own, but it uses a lot of energy.
Yes, high in sugar so carbs
Consuming whey protein can potentially kick you out of ketosis if it contains added sugars or carbohydrates. It's important to choose a whey protein powder that is low in carbs to maintain ketosis.
One cannot go into ketosis if too many carbohydrates are consumed. Thus, one needs to be able to do two things. The first is how to count to 20. Less than 20 grams of carbohydrates per day, and ketosis results. 20 grams of carbs is only around 80 kilocalories or calories to the general public not used to precise jargon. The second is learning to use ketone test strips which detect ketones in the urine and quantify how much, if any, ketosis is occuring.
You have to take 30 to 50 grams carbs per day on low carbs diet. Sixty is more, but not 'too much'.
Too much of anything is bad for you, and oats are carbs, so yes.
I knew someone that lost 130lbs on a Protein-Only diet in 1994; in eight months he had a little soda each day, (approx. 15g carbs). To this day he is still healthy, with no kindney-issues.
The principle behind Low Carbohydrate Diets is a process known as Ketosis. Ketosis is a process in which an individuals body metabolises Ketones for fuel instead of Carbohydrates. For most individuals it is necessary to stay below 15g of Carbohydrates per meal to maintain Ketosis.
Too much protein, not enough carbs.
Since a ketosis diet is very high in protein and very low in carbs it is not something you'll want to do long term unless absolutely necessary for medical reasons. One of those medical reasons for going on the ketosis diet is to treat epilepsy as it helps prevent seizures in children.
The Atkins diet is built on restricting carbs and filling up on fats. This puts your body in a state of ketosis so your body learns to burn fat for energy instead of carbs. It does cause weight loss but personally I wouldn't recommend it. You need carbs in your diet.
When carbs are eliminated or greatly reduced, the body begins using stored fat for glucose by the process of Ketosis. When abundant carbs are available the body stores the excess as fat.
Ketosis means that the body is burning fat for energy. There is nothing abnormal about this state. If the body is burning too much fat, it may be a health problem.
