Question I don't know how to count calories...

How many calories are kilocalories? I would think 1 kcal equals 1000 cal but that would mean 100 grams of low-fat yogurt would be 81 kcal and 81000 calories??????? And I'm suppose to get in like 1300 calories a day. And how many calories is 1 KJ? How many proteins am I suppose to take in for weight-loss again? In grams please I don't know how much 1 ov or whatever is. Not really looking for high protein diet but just I wanna take in just enough to keep my muscles and I'm a girl by the way so less muscular.

Re: I don't know how to count calories...

A calorie was defined a couple centuries ago as the amount of heat required to raise one gram of water one degree Centigrade. This is a tiny amount so the kcal (1000 calories) is used for food measurement. It's been shortened to calorie so EVERYTHING you read about kcals. is exactly the same as calories. Just forget the scientific definition (except in a Physics lab.)
A kilocaloire IS a Calorie for diet purposes.
(Forget about joules and kjoules if you live in the USA....just another measurement of heat more popular in Europe...for the curious 1 Kcal = 4.187 Kj.)
Food energy could just as readily be listed in kilowatt-hours !

On a 1300 calorie diet, maybe look to keep protein at 65 grams MINIMUM. THat should keep you healthy.

One ounce = 28.35 grams (say 28!)

You're going to need a good diet scale and an excellent nutrition value table like the US Department of Agriculture:
Type in the food and hit ENTER!

Re: I don't know how to count calories...

Oh wow, thank you so much. I've been having troubles with this forever, well thanks . Oh and do you know how much you burn (average) on a normal day of 24 hours, without going to the gym or doing sports or anything.
I'm 5"2 so I probably burn less.

Re: I don't know how to count calories...


If you tell me your age and weight I can get more precise, but as a ballpark figure, a woman, age 18-35 weighing 128 pounds, will maintain at about 2100 calories. (At 35-50 the caloric requirement is more like 1750....age makes a BIG difference, dammit!)
