Finally, note that fasting to induce ketosis can also trigger a set of symptoms often known as the “keto flu.” Fasting ketosis symptoms may include decreased energy levels, increased cravings, digestive issues, muscle aches and dizziness. These symptoms can last between a few days to a few weeks when starting the ketogenic diet, but they typically subside once your body enters ketosis and begins to adapt.

I have since reviewed another new and amazing intermittent program called Science Based Six Pack, you can read my full in-depth review of this program here, Science Based Six Pack Review. I have also purchased this program as well, and it is very thorough and detailed, as well as very user-friendly. This is my new number #1 recommended program for a highly effective intermittent fasting program.


Stable blood sugar levels are vital to the success of any diet. This is because when glucose levels plummet, it leads to intense hunger, which almost always results in binge eating. Stable blood sugar levels help eliminate headaches, lack of focus, poor memory, and brain fog as well. Interestingly, these are common complaints among those who follow high carbohydrate diets, as opposed to diets that are rich in fat and protein.
Islam is the only major religion that engages in a fasting practice reflective of intermittent fasting in terms of both food consumption and diet consistency.[12] The duration of the Ramadan fast is between 28 and 30 days, depending on the year, and consists of not eating or drinking from sunrise until sunset.[12] During the holiday, Muslims eat twice per day: once in the morning before dawn and once in the evening after dusk.[12] A meta-analysis on the health of Muslims during Ramadan shows significant weight loss during the fasting period of up to 1.51 kilograms (3.3 lb), but this weight was regained within about two weeks of Ramadan ending.[13] The analysis concluded that "Ramadan provides an opportunity to lose weight, but structured and consistent lifestyle modifications are necessary to achieve lasting weight loss."[13] Negative effects of Ramadan fasting include increased risk of hypoglycemia in diabetics as well as inadequate levels of certain nutrients.[12]
You are probably wondering how there could possibly be a benefit to eating less frequently that goes beyond what you are already getting with a ketogenic diet. Restricting carbs and eating enough fat and protein does come with a plethora of health benefits, but when you add intermittent fasting to your lifestyle you can increase energy and reverse aging by harnessing the power of a nobel prize winning process.
Fast for 16 hours of the day, and allow yourself a single eight-hour window for eating. This may be a good option for most beginners, because it represents the most subtle change from the standard three-meals-per-day lifestyle. As approximately eight of those fasting hours should be spent getting a good night’s sleep, that leaves only eight hours where participants need to be consciously avoiding food. For many, allowing themselves to eat normally from noon until 8pm gives them a stable meal schedule while also staying in a fasted state for the majority of the time.
Fasting on keto can be incredibly beneficial, especially if you’ve reached a plateau and aren’t seeing results from the ketogenic diet alone. While it’s not required, keto intermittent fasting can bring the benefits of your diet to the next level and help optimize your health. It is also thought to speed up ketosis by helping your body burn through glycogen stores more quickly, which can help sidestep symptoms of the keto flu to get faster results.
As a functional medicine practitioner, I see a wide range of health problems that all stem from chronic inflammation. And while acute inflammation is a natural and healthy response to help fight off pathogenic bacteria and infections, long-term chronic inflammation that doesn’t subside when the threat is gone can contribute to everything from autoimmune conditions to cancer.
I dont think this test presents the whole picture. Dairy products can spike insulin levels based on the protiens (not the carbs) in dairy products, without raising blood glucose. When intermittent fasting, part of the benefit is to take insulin out of the picture during the fast. You could be increasing yur insulin levels using dairy products but not see a change in blood glucose.
Eating all your meals in an 8-hour window (say, eating between noon and 8PM, and fasting the other 16 hours a day) causes significant weight loss without counting calories.[1]  While this type of intermittent fasting causes weight loss no matter what people eat, research shows that people who do it in a healthy manner lose twice as much weight (7% vs. 3% of their body weight) as those who fast while still eating junk. So it’s still important to follow a high-performance diet like the Bulletproof Diet while you fast.

Is intermittent fasting safe? Remember that you’re only supposed to fast for twelve to sixteen hours and not for days at a time. You’ve still got plenty of time to enjoy a satisfying and healthy diet. Of course, some older women may need to eat frequently because of metabolic disorders or the instructions on prescriptions. In that case, you should discuss your eating habits with your medical provider before making any changes.

Even though this plan is advanced, it's very simple. Don't eat anything every other day. This is the most intense form of fasting but can produce amazing results. Every other day, eat healthy fats, clean meat sources, vegetables, and some fruit, and then on your fasting days, you can consume water, herbal tea, and moderate amounts of black coffee or tea.

If you have an addictive relationship with food and you struggle with portion control, track your calorie intake in your meals to make sure you’re not overeating. If you skip breakfast, you might be so hungry from this that you OVEREAT for lunch and this can lead to weight gain. Again, the important thing here is that with intermittent fasting you’re eating fewer calories than normal because you’re skipping a meal every day.
