What is a keto diet?
The keto diet is a very high fat (70-80% of total calories), extremely low carb (less than 80g but can be reduced to 20-30g per day), moderate protein diet.
What is ketosis?
The idea is that when you deprive your body especially your brain of its primary fuel source (carbohydrates -starchy veg, all grains, all sources of sugar or fruit) it forces the body to use an alternative fuel source, fat for energy instead. This causes the body to produce something called ketones. These are chemicals made by the liver that can be used by cells for energy. When you are in this state, it’s called being in ketosis.
Is a keto diet safe?
A ketogenic diet could be an interesting alternative to treat certain conditions, and may accelerate weight loss. But it is hard to follow and it can be heavy on red meat and other fatty, processed, and salty foods that are notoriously unhealthy. We also do not know much about its long-term effects, probably because it’s so hard to stick with that people can’t eat this way for a long time, so we need more evidence to fully understand long term effects.
How do you know when your body is in ketosis?
