Ketosis is bad if it is not carefully controlled. It also gives a peculiar odour to the breath, which although not as unpleasant as the bacteria caused 'bad breath', is still not nice. Sometimes, as with diabetes sufferers, ketosis rampages out of control.

Sometimes with the Atkins method, there is an odour present that is caused by fungal overgrowths. The normal flora in the gut are disrupted and the one that causes thrush can get out of hand. If the ketosis is carefully managed, it should not be a problem. It does state quite clearly in the book, more than once, and sometimes more than once a chapter, that you must keep checking with your GP if you already suffer from chronic illnesses, like diabetes, asthma, heart conditions etc.

Whilst losing excess weight has to be good in the short term, it's easy to get carried away and continue with Induction (although it is safe for most people to do so for a little longer) much longer than advised. When you see pounds melting away with little or no effort, no weighing or counting calories, no crispbreads or tasteless protein drinks, then it is very very easy to slip into overkill.
