> Fasting releases toxins into blood stream

Nonsense. What 'toxins'? Where are these 'toxins' from? What are there effects on the body? What scientific papers detail these 'toxins', their chemical makeup, source, etc?

'Toxin' as a word has become a high-level indicator of pseudoscience and homeopathy-style unscientific health advice. If you see someone using that word, always question or ignore their advice. It's the 2000s version of the Victorian era 'impurities' which were leached or vomited from the body to return to health.

It's possible that parent is referring to the mild acidosis that can accompany ketogenic diets or fasting. At some point along the process of using fat, rather than glycogen, for fuel, your body's compensatory mechanisms (bicarbonate buffering, renal excretion, and a few others) can't keep up with the acid in the blood stream, causing a lower pH.

I'm not going to take a guess at 'toxins.' When I hear that terminology, I think of a blindfolded kid trying to hit a pinata with a bat, or carpet-bombing: they'll get there eventually if only by the imprecision of their targeting, but it's not pretty.

Yes, fat burning releases 'toxins' which are accumulated there. It is a problem when fasting for extended periods (week+).

I don't agree, at all. I'm French and I love food, and cooking. I treat myself to a super meal before I start fasting... Never had a headache! I try not to hit the bottle too much tho, there's nothing worse than a hangover at a time you /can't/ eat ;-)

As for emergency supplies; on the contrary; just CLEAR the fridge, remove any temptation. I usually prepare/buy meals for my wife, but I try to make them quick to prepare and not too smelly. No need to torture myself smelling her lovely little dinner ;-)
