XP Nutrition Keto – The cons of the Keto Diet“As with any diet, there are always pros and cons,” says Devje. If you follow the ketogenic diet, you may notice side effects such as bad breath, headaches, nausea and fatigue. You might also feel bloated or constipated — and you may feel the need to urinate more frequently, since ketosis acts as a diuretic, says Jalali. In addition to weight loss, studies show that the ketogenic diet may also be helpful in treating many other conditions, such as type 2 diabetes, polycystic ovary syndrome , acne and more. Currently, it remains unknown if the potential benefits of the keto diet for weight loss outweigh the health risks.Hi Johnette, I have followed a low carb lifestyle while nursing both my children, but I can’t give medical advice. I recommend checking with your doctor, preferably one familiar with the low carb lifestyle. I like reading all the positive reviews and am willing to give this a try.
