Hi everyone. I have 3 quick questions. They might be stupid questions but here we go:
Lets say I run 7 miles on a cold day and then I run another 7 miles on a hot day, would I be burning the same calories both days? Does the weather have any effect on the body ( burning calories )?


I sweat a lot when I run, lose lots of water, but I have a friend who does not sweats at all ( and if he does, very little) and runs the same as me. Even when we have a soccer game he sweats nothing. My question is: Does sweating relates to the calories burned? wut I mean is that if sweat is a sign you are burning calories or you don't need to sweat in order to burn cals?

This question is out of topic: How often do you guys drink coffee? is it beneficial in one way or another, or is it just bad? From wut I know or have heard it retains water, but I haven't heard anything else besides that.

Thanks.

Carlos

I would say you generally burn more calories on a cold day because your body has to maintain your body temp more than normal. I don't know about the coffee or sweating.

i dunno.. but it gets super hot here in phoenix az...

i feel like i burn calories the minute i step into the sun... *sizzle sizzle*

You body sweats to cool you off. That's the only purpose.


Unfortunately, sweating doesn't mean that you're burning calories. "Sweating is the way your body cools itself. Postexercise weight loss often represents a loss of fluids from the body, not a reduction of fat," says Thompson. "People sweat because their body temperature increases ó often times when you work out, your body temperature goes up and that's why sweating is associated with exercise. But that's where the relationship ends."

Actually, if you are just beginning an exercise program and you're sweating excessively, you should be very concerned. "It's a real mistake to monitor your level of exercise by how much you're sweating because excessive sweating can bring on heat exhaustion, followed by heat stroke," cautions Thompson. Experts suggest focusing on replacement of fluids rather than focusing on the alleged pounds lost. For every pound you lose following exercise, you should drink at least 24 ounces of fluid.



If sweating did increase calorie expenditure, then everyone would be sitting in saunas.

Thanks. How about the coffee or the other ques. I asked.

these are all great questions and IMHO deserving of a thread for each.
This temp. question is one that I have pondered for quite a few years.
The bottom line is yes, if your body is above or below 98.6 you will have to burn extra calories to raise/lower your core temp. I haven't come across any measurement of how many calories burned in what time frame etc...but I'm sure its out there...


In theory, raising the temperature of 1 liter of water by one degree Celsius (from body heat or any other heat) takes 1,000 calories.
The lower the temperature of the water the faster this would happen.
If all of the warming of the water came from body heat then in theory the body would have to replace this by burning 1,000 calories of fat (or sugar).

The body must remain at about 37-degrees Celsius (98.6-degrees Fahrenheit) to function normally.
So iff extracting heat from someone fast enough to make some fat burning difference, hypothermia would quickly set in.
This is a condition in which the body temperature decreases below 37-degrees Celsius and shock begins to set in (lowering of blood pressure and repiratory rates).

In concluson, for losing weight there is no substitute (including the Cold Water Vest) for moving more (i.e., exercise) while eating less (i.e., well- balanced weight loss diet recommended by a doctor familiar with your health).

Calorie (cal): A calorie is the heat required to raise the temperature of 1 gram of water 1oC, from 16.5o C to 17.5o C.

1 calorie = 4.184 joules (J)
http://www.webdesignpros.net/wellness/calories.html



suppose that you drank water that was 50 degrees Fahrenheit. Your body must burn a few calories to warm the water to body temperature of 98.6 degrees. To raise one pint of 50 degree water the 48.6 degrees to body temperature, about 12.25 calories are burned. That doesn't sound like much, but suppose you drink only 3 pints a day for a year; that's almost 4500 calories or 1.4 to 3.1 pounds of weight loss.

If the water were colder, say ice cold, or if more water was drunk, more calories would be burned and more weight would potentially be lost.

There is also a slight "carry factor." Your body must burn a few calories just to carry the weight of the water you drink. A pint of water is said to weigh a pound, so carrying that pint inside your body is like carrying a one pound weight in your hand. Your body will burn a few calories simply to tote the weight around.

For the cold water diet, the "carry factor" is not very great, but over a year it will amount to the loss of more than an additional pound. Supposing you "carry" the pound of cold water during 18 hours of the day, you'll burn about an extra 4100 calories per year. On average, that would represent about 1.9 pounds of additional weight loss.

Your body's "appestat" is located in the brain near the "thermostat." If your body temperature drops, your appetite increases and you experience hunger. Eating "stokes the furnace," generates heat, and helps warm your body. Hence, winter exercisers should always carry carbs with them for fuel. Winter campers, for example, commonly keep a supply of dried fruit, chocolate or cookies nearby, so they can "stoke the furnace" if they wake up cold in the middle of the night.

Food's overall warming effect is known as thermogenesis (that is, "heat making"). Thirty to sixty minutes after you eat, your body generates about 10% more heat than when you have an empty stomach. This increased metabolism stems primarily from energy released during digestion. Hence, eating not only provides fuel but also increases heat production.

If you drink a gallon a day, 4 liters, that's only 140 Calories. That's a lot of water. Plus you put stress on your body drinking that much, as it has to
fight to keep from losing ions.

Sweating is your body's mechanism to dissipate heat.
The hotter your body gets the more it will sweat, plain and simple.
There are a few possibilities why your friend doesn't sweat much:
he weighs less
he doesn't eat before exercise
he has a faster rate of respiration
his clothing allows his body to remain cool
etc...

Great answer man!! but you said that if I drink a gallon of water I would put stress on my body, does that mean that by drinking that much water isn't really good? thanks.

I just search google for keywords and post anything interesting I find...
I don't know anything, I don't mean to give any impression that I do!!


It is possible for a person to drink too much water.
It is called water intoxication.
What happens is the sodium level in the blood reaches very low levels (because of dilution by excess water which can only be excreted in the urine, sweat or breath). This disturbs water balance in the brain, which can cause epileptic seizures and even death.

Research has shown that a person can safely drink up to 10 liters of water a day. An exception would be persons with kidney disease who are limited in the amount of water they can drink per day. Persons with bladder infections benefit from increasing their water intake.
http://www.dietitian.com/fluids.html



A large volume of water thins the blood and can actually make you "drunk." It washes water soluble nutrients (such as B vitamins) from the body. For a few persons with congestive heart disease or other conditions, serious edema or other conditions might occur. The kidneys have to work harder to remove the excess water from the body and that too must be taken into account. Someone drinking a lot of water would have to take vitamins and minerals to replace those purged from the body and would have to carefully avoid salt.
http://www.prisoners.com/cwaterd.html



"water intoxication." Is usually associated with long distance events like running and cycling, itís not an unusual problem.
For example, water intoxication was reported in 18% of marathon runners and in 29% of the finishers in a Hawaiian Ironman Triathlon in studies published recently in the Annals of Internal Medicine and in Medicine & Science in Sports & Exercise respectively.

What happens is that as the athlete consumes large amounts of water over the course of the event, blood plasma (the liquid part of blood) increases. As this takes place, the salt content of the blood is diluted. At the same time, the athlete is losing salt by sweating. Consequently, the amount of salt available to the body tissues decreases over time to a point where the loss interferes with brain, heart, and muscle function.

The official name for this condition is hyponatremia. The symptoms generally mirror those of dehydration (apathy, confusion, nausea, and fatigue), although some individuals show no symptoms at all. If untreated, hyponatremia can lead to coma and even death.

Enough, but not too much. The fluid requirement for the majority of endurance athletes, under most conditions, is about 8 to 16 ounces per hour. There is considerable variation here, of course, due to individual sweating rates, body size and weight, heat and humidity, and running speed, and other factors. Still, much more than this amount of fluid is, in most instances, probably physiologically excessive as well as uncomfortable, as liquid sloshes around in the gut during the activity.


It is now thought people should follow the dictates of thirst and not to exceed 1-1.5 quarts per hour
http://healthfactsandfears.com/featured_articles/jul2003/water072403.html

1 liter = 4.22675282 US cups
1 US gallon = 3.7854118 liters
1 US cup = 8 US fluid ounces
1 US quart = 4 US cups
1 US gallon = 4 US quarts

SOO!!! it appears that
4-6 cups, or 32-48oz per hour is close to the limit

and 42 cups, 336oz, 2.65 gallons is around the safe daily intake limit, although its considered VERY high and beyond overkill

Damn I have to lower the water to 1 gallon a day. I play soccer and when I run I sweat as hell. Yesterday I run 11 miles and lost 4 pounds of water weight. I felt so weak after the running. Anyways, I am not used to drink sports drinks but I will start to drink them since by drinking water you are cleaning out the vitamins. Great help man. Thank youuuuuuu veryyyyyyy muchhhhhhh. See ya.

I have thought about this myself for some time now!! Best question yet, however if you look in nature such as places of Africa or Iran and other Desert areas you will find the same fat and skinny types of people. It has to be centered directly on Cals witch is why the people who do not eat a lot have not muscle and no fat! lol Also you will never burn the same amount of Cals on 2 different run even if they are the same length because humans have a very hard time doing the exact same thing twice. So I really wouldn't worry about that one to much. As for the coffee, drink water! lol Everyone else pretty much nailed the head on the coffin with the sweating so I don't need to touch that one. But I hope this helps and good post Geoffgarcia interesting stuff

take two of the one a day Vitamins a day if you drink more then a gallon or you could just add a Lemon to the water to help out. If you drink under or right at a gallon you have no need to worry about anything.

There are no Vitamins in Gatorade either... just potassium and that is only 30mg per serving you can eat a banana and get more potassium then that!

I have another ques. I play soccer and run a lot. After a game, strong training, or a long run ( 9 to 13 miles) wut would be a good food to eat to recover the energy lost. Should I eat a big meal or just a small one. Thanks.

Drink a lot of gatorade after something like that. Also a meal would be good, but your body needs lots of quick burning carbs to recover (and salt I believe).
