caloric intake for weight loss
[intro] we here at scishow want you to keep beingcurious -- about the world, the universe, even what’s going on in your own body. and that is why we’ve teamed up with googleand youtube to answer ten of the most popular science questions searched on the internet.
caloric intake for weight loss, i'm michael aranda, and this is the world’smost asked questions. today’s question: how many calories shouldi have in a day? you’re probably asking because you wantto know how many is too many. after all, you know that if you take in more energy thanyou need, your body will store that excess
energy as fat. but before we can talk about how many caloriesyou need, let’s start with what a calorie is. the calories that you find on food labelsaren’t the same as what scientists call calories. in chemistry, a calorie is the amount of energyit takes to raise the temperature of one gram of water by one degree celsius. but the calories listed on your can of sodaare actually kilocalories -- each one equal to 1,000 of the “small calories†thatchemists use to measure energy.
so when your soda pop says it has 150 foodcalories -- you’ll notice it’s written with a capital c -- that’s the same as 150,000small calories -- with a little c. so that’s enough energy to raise the temperatureof a whole liter of water by 150 degrees. kinda puts things in perspective. but how many calories you need depends onwho you are, and how you live your life. first, there’s your age to consider. despite the stereotype of the ravenous teenager,your calorie demands actually peak when you’re in your mid-20s. that’s when your metabolism is higher thanat any other point in your life, and because
you keep growing into your 20s, once you'redone, you have more lean muscle mass which requires more energy to maintain. so, depending on your lifestyle and otherfactors, when you’re in your 20s, you may need from 2200 to 3000 calories a day! your sex is a factor, too. men tend to havemore total body mass, and more muscle mass, than women on average, so their caloric requirementscan be slightly higher. according to the us institute of medicine,the average calorie range for an adult woman is 1800 to 2400 calories a day; for men, itcould be anywhere from 2000 to 3000. but that’s obviously a pretty broad range.and as delicious as it sounds, most of us
don’t need to be eating 3000 calories aday. and that’s because the most important factor,by far, that affects your calorie needs is your activity level. for example, if you’re a woman in your 30sor 40s, and you live a rather sedentary lifestyle -- meaning you don’t set aside time forany exercise -- then probably don't need any more than 1800 calories on average. but if you regularly take a nice brisk walk-- say between 2.5 and 5 kilometers a day -- then your caloric needs go up about 10%,to 2000 calories. and if you regularly walk more than 5 kilometers-- or burn the equivalent amount of energy
doing some other exercise, like running -- thenyou’re looking at another bump, up to 2,200 but when it comes to calorie intake, medicalprofessionals will tell you that the real goal is to focus on your energy balance -- that’sthe balance of calories you take in compared to the calories you burn through physicalactivity. so, naturally, if you burn more calories thanyou take in, you’re going to have to use more of the energy that you have stored upas fat. and, on the other hand, if you consume morethan you use, you’ll just keep building up those “energy reserves†around yourmidsection. since no one burns the same exact number ofcalories that they eat every day, the key
is to maintain energy balance over the longterm. so if you consistently ingest more energythan you use, you’ll be out of balance -- just as you would be if you keep burning more energythan you supply for your body. but, if you ask me? you look fantastic. now, scishow survey funtime! survey takerswho reported counting calories also reported getting hiccups less than other survey takers.interesting, but it's important to note that correlation does not equal causation. of all of the fascinating questions in theworld, what question do you want answered most? let us know on facebook or twitter ordown in the comments below and we will answer
the best questions in a new video at the endof the month. and don’t forget to use the hashtag #wmaq and stay tuned for other videosthis week.
