If heat is a form of energy then does food that is hot have more energy (calories) then food that is cold?

Question

example: does hot pizza provide you with more energy (calories) than cold pizza?

Answer 1

no

Answer 2

No, because heat is the energy that is transferred from the hotter substance to the cooler substance. A slice of pizza that is 400 Calories at 160 degrees will still be 400 Calories when colder. If it does make a difference, it is so minute that it is negligible.

Answer 3

Yes, heat is a form of energy, you use to cook food, or heat the house, etc. The energy you get from food (Calories) is the stored energy in food i.e: carbs, proteins & fats as a form of stored chemical energy, which in the presance of O2 empowers or energize muscles to function and do various body tasks.

A teaspoonful of sugar in cold lemonnade or a cup of hot cofee has same number of calories, if you know what I mean.

Answer 4

Yes. When you eat cold food, some of the calories are needed to warm it to body temperature. Some cattle ranches use solar heating to warm the cattle's drinking water so they fatten a little bit faster. Just recently it's been suggested that controlled temperatures inside buildings contribute to obesity. When your body regulates its temperature in a hot or cold environment, it burns up calories. And most of the energy input to the food you eat goes into transport, canning, freezing, cooking and making the container and packaging, not to the energy in the food itself.

Answer 5

Not really,
I believe the calories of heat (on a hot day) might cause you to burn more of the calories of food to remain cool.

On a cold day, the calories of heat would keep you from shivering and burning the calories of food...

The calories of food stay about the same in both cases.

Edit: the magnitude of the temperature engery is much different due to 38 calories of food is 38,000 calories of temp. I attached a link.

Answer 6

Nope.

The energy your body creates isn't created through the heat in your food.

Maybe if you're really cold it might work, but you'd need a moderation of cool/hot to stay at the perfect spot.

If you're too hot, then you get tired and exhausted easily. If you're too cold your body becomes tired from shivering in attempt to keep you warm.

Your body can turn food into energy, but not the heat in the food into energy.

Answer 7

No, the calorie content is the same whether you eat it hot or cold. The calorie count comes from what it takes for you to burn off the calories that you consumed, not the temperature the food was when you ate it.

Answer 8

I've heard that it is easier to absorb water that is warm, since it has to be heat up to 98.6 so your body can obsorb it. But with solid foods? I'm not sure, since we dont absorb much anyways.

but if you look at it. You cannot really increase the # of calories in something by just applying heat. Heat only causes the molecules to move more rapidly. To increase the calories of a piece of food, you have to ADD something to it (butter, grease, etc). Thats my explanation..... but I was a business major in college.....

Answer 9

The term of interest isnt energy, its "useful energy".

When you eat hot food there is more energy in your body, but not more useful energy. Your body cant convert a heated stomach tissue into stored energy, or work in the arm muscles. It requires chemical energy to do that.

Its like eating some radioactive iodine.. because matter IS energy you have more energy in you, but because your body isnt a nuclear reactor it cant convert the iodine into useful form.

Answer 10

not significantly

however, food that you eat that is hotter than body temperature, heats the body slighly, and your body gets to do a little less work keeping you hot (the body is always burning away keeping you at 98.6 F or thereabouts)

food that is colder than your body temperature will acutally burn a tiny bit more calories in the end, because the body has to do a little more warming

this affect is normally very small for normal food
but people caught outdoors for a long time in the winter, who get thirsty and eat snow for water, will succomb much more quickly than if they melted water on a fire and drank it

Answer 11

wrong. food which has same tempreture wount be resulting in more or less calories unless it is transfer to your body then burned by exsercise or more eficient house work or daily activites

but u might burn(destroy) or seperate calories out of food (in fat), by cooking or heating any food ( specially foods like ham,turkey which are full of fat or calories) so u might be right that, if u heat any foods you will not gain much energ if u don't heat or cook them. so its more healthy if eat some thing raw!"
