What happens if you exercise vigorously but do not eat?

Your body will go into starvation mode and start to shut down.  Your body will retain all it's energy for making your brain and heart work, but at some point those would shut down, too.

Personally, I cannot manage my health without working out. However, this all comes down to the input vs output.  That is, your daily routine requires energy.  If your intake of calories is lower than your output, you lose weight.  Look at marathon runners.  However, if you want only to be skinny, then that's the way to go.  Eat nothing and you will become malnutritioned.  If you don't exercise, your muscles will become soft, muscles can atrophy and you lose the powerhouse to burn energy.  Without much muscles and exercise, at this point, your bones aren't feeling the pressure you get when you work out, thus, less calcium will be deposited on your bones.  That is why people with osteoporosis are recommended to do exercises.  Without exercise, the stuff that holds your internal organs in place will become loose, thanks to gravity.  Skip ropes or running exercises can help tighten those.  You may see some people looking very beautiful and yet looks good and they don't do much exercise.  Well, maybe their metabolism is high and they are active during their daily routine and they don't eat much.  But then, who to say they will be healthy 20-30 years down the road?  Maybe yes, you can manage your shape without working out, by not eating tran fat and avoid fried food.  To guaranteed healthy life, regular exercise and a balanced diet helps a whole lot.  Sorry, I hope that answered your question.

even if you do no exercise at all u will still loose about 4 to 5 kgs. and if you feel energetic enough to shake a leg or two and indulge in light aerobics or brisk walking the results will be even more satisfying.

You CAN go immediately... however, you MAY become nauseous, light headed, dizzy, etc. \n\nSome folks have no problem eating and running (or swimming) immediately.\n\nHowever - for the most part one should wait an hour after eating to exercise. The reason for this is NOT that you will drown or die, LOL, but rather that your body is currently sending most of your "extra" blood supply to your stomach to digest food and it is simply not available to fuel your muscles. So, in an emergency or over-stress, you simply have no reserves. \n\nWhile you shouldnt run in that hour - you CAN however do pre-run stretching.\n\nAlso - be careful with the heat - like always. Lots of fluids. Light colored clothing. Try running in the morning or evening (although run only in the mornings if running in the evening keeps you awake at night). \n\nMost of all - enjoy!

Exercise *does* work. You just have to do it regularly and at a level where it is challenging to you but not so hard that you can't stick to it.\n\nAs far as diet, just don't eat when you're not hungry. That alone will help keep your weight under control no matter what foods you eat.

While research is limited, most experts recommend that if your symptoms are above the neck and you have no fever, exercise is probably safe. Intensive exercise should be postponed until a few days after the symptoms have gone away. However, if there are symptoms or signs of the flu, such as fever, extreme tiredness, muscle aches, swollen lymph glands, then at least two weeks should probably be allowed before you resume intensive training.

You will tone your muscles, but without changes in your diet you won't lose any weight.

Your body condition would get worse if you dont work out...you can eat like that...but you should exercise everyday even though you dont want to be skinny....~~!!  But tell you what....you cant slow down after you get fat, because your stomach would be bigger than before, and then you cant get back skinny again....== !!

Eat less - exercise more.

trust me - you don't want to do it! It's so bad for you. Plus, eating less just makes your metabolism slower. So once you start eating after those four days of not eating, you will gain weight more rapidly because you have slowed down your metabolism so much. If you are really trying to lose weight- try drinking only water and sugar free drinks like teas and juices sweetend with a sugar substitute, no soda, eating smaller portions every three hours and no later than 8 or 9:00 at night. Try to eat more proteins, whole grains, and fruits/veggies. It will balance your blood sugar making you feel more satisfied eating less. Eating more often (every 3 hours) will also stimulate your metabolism to help you lose weight. YOU DO NOT WANT TO STARVE YOURSELF.
