Now that you’re properly prepared, it’s time to get started with intermittent fasting keto. In addition to cutting carbs, increasing fat intake and restricting food consumption to a specific window of time each day, you should also be sure to stay hydrated and plan your workout routine around your fasting schedule. While exercising is okay during days that you fast, it’s important to listen to your body and avoid pushing yourself too hard.
What if we told you that the answer to losing weight, improving body composition, and feeling better isn’t about dieting, but instead skipping meals every once in a while? For some, intermittent fasting, or going a longer period of time — usually between 14 and 36 hours — with few to no calories, can be a lot easier than you may think. And the benefits might be worth it. If you think about it, all of us “fast” every single day — we just call it sleeping. Intermittent fasting just means extending that fasting period, and being a bit more conscious of your eating schedule overall. But is it right for you? And which method is best?
So how long does it take to go into ketosis when fasting? On a standard keto diet, it typically takes around 2–3 days to reach ketosis, although it can take up to seven days in some cases. However, many people find that keto adaptation intermittent fasting can speed up the process and help your body burn through glycogen stores more quickly to help enter ketosis.
People fast for so many reasons; some fast because they're trying to lose weight while others fast to improve medical conditions such as diabetes and high blood pressure. The science behind intermittent fasting has slowly been piling up, too, with research showing that participants of intermittent fasting experience a reduction in weight and inflammation and improvement in insulin sensitivities.
That’s what I suggest you do when you start fasting. It should happen naturally, and you shouldn’t have to force it. If you’re still a sugar burner instead of a fat burner, it’s going to be much harder…so if you’re serious about trying out this whole fasting thing, I suggest slowly transitioning to a high-fat low-carb diet.

Yes, by cutting out an entire meal each day, you are consuming fewer calories per week – even if your two meals per day are slightly bigger than before. Overall, you’re still consuming fewer calories per day. This is highlighted in a recent JAMA study[b] in which both calorie restricted dieters and intermittent fasters lost similar amounts of weight over a year period.
