In order to get into ketosis you have to give up all sugars and carbohydrates. Basically a Ketosis diet means only meat and eggs and lots of water. My body can not have more than 25 grams of carbs a day in order for me to maintain Ketosis.ou do not need to give up ALL carbs to get into ketosis. You will need to eat a LOT of vegetables-just not high carb veg. I eat tons of salad, mangetout, broccoli, aubergine, spinach, etc.
