The Truth about Juice DETOX…
After the first sip
Your brain’s hunger signals are answered with a hit of pure fruit-juice sugar. And don’t get any ideas – vege-based cleanses aren’t any healthier. The sweet stuff prompts the pancreas to squirt out insulin, prostate which moves sugar – now in your blood in the form of glucose – into your cells.
After 30 minutes
As your cells suck up the glucose, asthma your blood sugar level can start to plummet and you may feel dizzy.
Meanwhile, lacking enough kilojoules, your body is operating off its supply of glycogen, a form of short-term energy stored in the liver and muscles.
After two days
With each shot of juice, your insulin levels skyrocket… then crash. Your glycogen stores are pretty much gone, leaving your tank empty – and you feel weak and listless. Since you’re getting only about half the kilojoules you need, your body draws on two long-term power sources: triglycerides, a type of energy stored in fact cells and protein, taken straight from your muscles. You begin to lose muscle mass, even if you’re still exercising every day.
After three days
Your brain is not happy. It enters into semi-starvation mode and gobbles ketones – fuel that comes from the breakdown of fat. Ketones work, but they’re like low grade petrol; as a result, you may feel unfocused or irritable. (Any “mental clarity” is more likely due to a strong placebo effect.)
Without a fresh protein infusion, your brain’s also lacking amino acids, the raw materials neurotransmitters need to maintain your mood. If you’re prone to depression, you may start feeling down.
The proteins in your shrinking muscles break down into ammonia and uric acid, unwelcome chemicals that invade your bloodstream. Now your kidneys are busy detoxing your detox.
Stay close to a bathroom; the juice’s high carbohydrate load causes a flood of water to enter the intestines. That extra H2O in your gut means you may get diarrhoea.
After four days
With no food to digest, your small intestine feels ignored. It’s villi – the rows of tiny fibres that move food elements into the blood – start to waste away. Your diarrhoea may get worse, leading to dehydration … and there goes your rosy glow.
On the eighth day
Solid food! But you’ve lost muscle. Even if you go back to normal eating habits, you have less muscle mass to burn those kilojoules; instead, the kilojoules are more likely to be turned into fat. One reason yo-yo dieting makes it harder to lose weight; a reduced muscle-to-fat ratio messes up your metabolism, making kilojoules harder to work off. Which is lose-lose really.
