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!

If you want to lower your time by 3 minutes, you must run longer distances before you run the 2 miles.  Run 4 miles at a good pace. Then 3 at a quicker.  The body will adjust accordingly. If you then practice a 2 mile pace, continue to run at a quicker pace before hand.  This way the body is better fit for the race.  Attempt to increase in your heart rate before running so the body is already going.  I recommend jumping jacks because its less stress than runningan extra lap.

It take 20 minuets of running before you get your hart rate up ,so try to run more then 20 min.That's when you burn calories. go for 5 min more at a time. when you first start to loose wight might see your pants getting loose. and as you loose the fat your but will get smaller, but also as you build up the muscle it will get bigger.  try to do at least 2 or more miles a day. also if you are going slow enough that you can talk freely ,then you are going to slow to burn calorie's.you should be going fast enough that you can't talk freely but not much faster then that. or you can't goo the long distance. another thing is to eat a small something before you start, this kicks in your metabolism and  also cause's More calorie's to burn .

How many hours or minutes you should eat before exercising depends on each individual. I wait 30 to 50 minutes after eating before I exercise, but your body may not be able to wait 60 minutes. Listen to your body. If you feel sick after waiting 30 minutes, wait longer. If you feel like you don't have enough energy after waiting 60 minutes, exercise sooner.\n\nAs for after exercising, I've always heard that it's best to eat something 30 minutes to an hour after hydrating. However, just like eating before exercising, it probably depends on the person.

Normal transit time through the stomach ranges from 1 to 4 hours.  Transit time is faster for meals very low in fat and can be significantly less than an hour.  Hot tea with a meal can also speed up the transit time - getting your stomach to empty quicker.  I actually try to work out before eating - but find that dinner at 8pm doesn't really work so well if you want to be part of a family meal.\n\nSo - dinner with high fat - take more time before your run\nlow fat - 30 min to an hour depending on your makeup.\n\nTweak the whole thing with hot liquid at the start of your meal.  Best wishes -

You should be OK, listen to your body you may want to cut it a little shorter than 18 miles.If you have been running you really should be OK\n\nPS you might want to ask this question in Diet and Fitness. Most of us runners seem to be there more often than sports.

it is generally said that carbohydrates should not be eaten after 7.30 - 8. thereshould be a gap of about 2.5 hrs between your dinner and sleep.

Here are the golden rules: \nNever eat carbs within 2 hours of exercise or within 1 hour of exercise. \nYou can eat protein straight after or before but it needs to be pure like a protein shake or protein bar for example. \n\nYour metabolism also works better if you exercise first thing in the morning on an empty stomach. So if you go jogging at 5.30am for one hour, you need to eat a wholesome low gi breakfast at 7.30am like some oats w protein powder. \n\nIf you eat carbs your body is not eating into your fat stores rather it eats into your carbs instead as it replenishes back what it just worked off. \n\nHope this helps good luck!

i know for a fact that if you wanna lose weight the best time of the day to run is early morining before you have eaten anything. if you havnt eaten anything you dont waste ur energy trying to burn what you just ate. instead your body burns the stored fat for energy then you have the rest of the day to burn the other stuff and you have a head start and you dont have do worry bout it. running in the moring will also increase you metabolic rate  for the day so you can eat more of the foods you want.   \nI reccomend you read The Complete Book of Running By James F. Fixx

When it comes to sports nutrition, your weight makes you and ideal candidate to eat anything you would like, within reason.  There are a number of factors, other than the surface question to take into consideration, such as what is the length and/or duration of your run and the intensity with which you run.  If you are currently not eating before your runs, try having a snack consisting of carbohydrates and protein (i.e. a peanut butter and jelly sandwich on whole grain bread).  You will need to find what works best with your body, and this will take some trial and error.  Hang in there, and you will find the right balance of when and what to eat.  Also, look for articles and advice from Nancy Clark.  She's a sports nutritionist with great advice and number of columns on sport websites in addition to other publications.

Minimum 5 weeks if you are under 20, and that includes training for +/- 2hours, 5 days a week.\nOver 20-25 the time roughly doubles.\n\nThe best meals are low in fat, high in protein, good carb count, and high in fruits.  Lots of water is a must.\n\nYou basically have to flush your bocy and begin building up.\n\nIf you are already in decent physical shape, you can reduce the total time to half.  But remember, its not all running.  Training has to include ball skills and tactical awareness.

an hour before the event you can eat something light but full of energy like oats or a small plate of cereal or banana or a snack bar. and also drink lots of water before hand don't want to get dehydrated. wear comfortable running shoes, and light clothing.

Although you have eaten, it was 5 hours ago. the fact that you are feeling sick is your bodies way of telling you your blood glucose levels are low. Your body uses glucose for energy and you are using a lot of energy whilst running.\nBest thing would be to have an energy drink whilst running or leaving 2-3 hours after eating, before running. \nJust don't eat anything too heavy. Complex carbohydrates are a good supply of slow releasing energy (pasta, rice, wholemeal bread etc).\nIf you are worried and this has never happened before, it is probably an idea to go see your doctor. if you you live in the UK you could get the advice from NHS direct (telephone helpline)

bananas are great, cause they're full of potassium, which breaks down the lactic acid in your body, and thus stops your muscles aching after having run. \nabout 4 days before running (if it's long-distance) i carbo-load (i.e. bread, rice, pasta) giving me a good source of complex carbs to slowly give me energy as i run.\njust before running i eat chocolate to give me a quick burst of energy and to accentuate the performance of adrenaline.

No, you should wait at least 15 minutes after eating because that allows your saliva to digest your food.

it is better if you walk before eating food.coz the intake of food causes blood supply to the digestive system ,increase by many folds,major part of the blood in the circulatory system[body] is diverted to digestive tract.so it is best to rest after eating so that heart is not over loaded with additional work of supplying blood to active walking muscles. it is advisable to rest for one hour after walking to eat food. and rest for 1 to 2 hours after taking meal.

It depends on the persons VO2 Max (how efficiently your body metabolizes oxygen in the blood).  A ten minute mile should be a fair jog but easily attainable for most, a five minute mile however is near impossible for (my guess) 98% of Americans.  An average one mile (sprint) for an average runner I believe is in the 7:30 minutes to 6:30 minutes range with some training of course.\n\nFor example I ran the Los Angeles Marathon (26.2 miles) and on my first attempt I finished 7,688 out of 25,000 and my average mile time was over 10:00 minutes per mile.  Less than 5% of all Americans will ever run a Marathon.
