Often, simply restricting carbs to extremely low levels results in ketosis. So this might be all you need to do. But the remainder of the list below will assist ensure that you achieve success.

If required, add intermittent fasting. For example, avoid breakfast and only eat throughout 8 hours of the day, fasting for 16 hours (i.e. 16:8 fasting). This works at improving ketone levels, in addition to speeding up weight loss and enhancing insulin resistance.60 It’s likewise generally easy to do on keto.
Add workout. Adding any kind of exercise while on low carbohydrate can increase ketone levels moderately.61 It can also help accelerate weight reduction and enhance type 2 diabetes.62 Exercise is not required to enter into ketosis, but it may be handy.
Sleep enough and decrease stress. The majority of people take advantage of a minimum of seven hours of sleep per night, on average. And try to keep tension under control. Sleep deprivation and tension hormones raise blood sugar levels, slowing ketosis and weight-loss.63 Plus they might make it harder to stay with a keto diet and resist temptations.64 So while dealing with sleep and tension will not get you into ketosis by themselves, they are still worth considering.
