Diet vegetables juice
After the first sip
Your brain's hunger signals are answered with a dump of pure fruit-juice sugar. And don't get any ideas—veggie-based body cleanses aren't any healthier.
The sweet stuff prompts the pancreas to squirt out insulin, 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, your blood sugar level can start to plummet and you may feel dizzy.
Meanwhile, lacking enough calories, 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 on empty—and you feeling weak and listless.
Since you're getting only about half the calories you need, your body draws on two long-term power sources: triglycerides, a type of energy stored in fat cells (woo-hoo!), and protein, taken straight from your muscles (oops). 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 gasoline; as a result, you may feel unfocused or irritable. (Any "mental clarity" is likely due to a strong placebo effect.)
Sans a fresh protein infusion, your brain is also lacking amino acids, the raw materials that neurotransmitters need to maintain your mood. If you're prone to depression, you may start feeling blue.
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 near the bathroom: The juice's high carbohydrate load causes a surfeit of water to enter the intestines. That extra H2O in your gut means you're apt to get diarrhea.
After four days
With no food to digest, your small intestine feels ignored. Its villi—the rows of tiny fibers that move food elements into the blood—start to atrophy. Your diarrhea may get worse, leading to dehydration... and there goes your rosy glow.
On the eighth day
Solid food! But uh-oh—you've lost muscle. Even if you go back to your regular eating habits, you now have less muscle mass to burn those calories; instead, the calories are more likely to be turned into fat. (Hence, one reason yo-yo dieting makes it harder to lose weight: Your reduced muscle-to-fat ratio messes up your metabolism and makes calories much harder to work off.)

I juice often, actually2012-04-26 08:59:04 by BorderlinePD
My diet is pretty flawless - I'm a nutrition nerd, mostly raw vegan - a little obsessed with organic raw fruits and vegetables and I juice all the time, actually. am also very active.
this lifestyle has always kept me busy and my "demons" at bay so to speak, but lately I'm finding it harder and harder to maintain and recently I've become a little apathetic about diet and exercise - just not as enthused as I used to be.
IMO Med Diet is too high in carbs2011-10-19 10:16:16 by k-dingo
Unless you're going with a real Medeterranian diet, which is mostly vegetables, and has few grains or pasta.
I find the focus on a specific diet is myopic. What you want to do is reduce/eliminate processed/refined carbs to the maximum extent possible: sugar, HFCS, flour, baked goods, soda, fruit juice (liquid sugar), and starchy vegetables. Some whole grains are OK, but preferably immediately following exercise, or a small quantity in the morning.
Emphasize: tons of green/leafy vegetables, sufficient protein (plant and animal sources both work, I prefer including meat in my diet): beef, chicken, bison, fish, eggs, dairy, legumes, quinoa, buckwheat, others
Atkins diet not great long-term2010-02-24 21:27:58 by unclemax
Firstly because of the high protein.
And secondly Atkins did not differentiate between refined carbs and unrefined carbs.
Refined carbs (sugar and flour) ARE bad if you are trying to lose weight, but unrefined carbs are not bad. You need lots of plants (vegetables,fruits,beans,seeds,nuts,whole unground grains) in your diet to have a healthy diet. Eat fruit and root veggies only with a meal. Avoid fruit juice.
