In recent years, intermittent fasting has been heard a lot and more and more often I hear people who come to the doctor's office or who do sessions with me through the internet, tell me that they follow it. Unfortunately, in many cases this should not have happened, for intermittent fasting has risks. Today we will see in which cases you should avoid intermittent fasting or at least have your doctor's approval before starting. You should not start intermittent fasting if you have diabetes. Even if you are not taking any medication, you should not start intermittent fasting without first talking to your doctor. The risk of experiencing hypoglycemia is significant. You should not start intermittent fasting if you have a problem with sugar metabolism. Even if you have not been diagnosed with diabetes, but have been told at one time that your body does not metabolize sugar well, or that you are predisposed to diabetes, or that you have hyperinsulinemia, or that your body does not accept sugar, or anything similar, you should not start intermittent fasting if you don't talk to your doctor first. You should also not start intermittent fasting if you have hypotension. Fasts, even short ones like intermittent fasting, are associated with hypotensive episodes. Although hypotensive episodes do not directly threaten health, it is possible after a fall that one maybe injured, sometimes significantly. If you are taking any medication you should still not start intermittent fasting. You should only start if you talk to your doctor and they agree. Although unfortunately, it is not obvious to many, but you should not start intermittent fasting if you are underweight. The risks to your health and your metabolism may be greater than you might imagine. If you have a history of eating disorders, you still shouldn't do intermittent fasting, whether it's anorexia nervosa, bulimia nervosa, or binge eating disorder. If you suffer from frequent binge eating episodes it is very likely that you suffer from binge eating disorder and in this case you should not do intermittent fasting. We know that prolonged abstinence from food increases the chance that your body will react with binge eating episodes and essentially push you into binge eating disorder, and if you already suffer from binge eating disorder, push you into bulimia nervosa. If you suffer from binge eating episodes, you should definitely talk to a doctor before starting intermittent fasting or any other form of fasting. And what I'm about to say may sound a bit self-evident, but even the self-evident must be said. Do not start intermittent fasting if you are trying to conceive. This is true for both sexes, but perhaps a little more so for women. All fasts we know suppress the reproductive mechanisms significantly. If you need to lose weight and you are in the process of reproducing do not follow any form of fasting. Prefer a balanced diet without long gaps between meals. Finally, the most obvious of all. Do not do intermittent fasting during pregnancy and breastfeeding. There are many ways to help you maintain your weight or even lose weight during pregnancy and breastfeeding and intermittent fasting or any other form of fasting is the most wrong way. In this case you should prefer something that your gynecologist approves. Instagram nutritional messiahs recommend intermittent fasting to everyone and everything. Do not rush to listen to them. They can be very persuasive, but advice from non-experts has risks. Now, if you're not in one of those situations where intermittent fasting is contraindicated, and you're seriously considering starting it, or you're already doing it and want some advice from an expert, then I'd suggest you watch the video featured on to my right that will answer the most frequent questions I hear in the clinic about intermittent fasting. I also remind you that by writing comments and pressing "like" on the videos you help me a lot. Thank you very much.
