i'm sending you all back to the classroom with this post! if you want to lose weight, change your body, and reach those weight loss goals, you have to be smart about it. you must know the basics. the first lesson anyone needs to learn when approaching a weight loss goal is understanding what calories are. simply put, a calorie is a measure of energy, just as a volt is a measure of electricity, a pound is a measure of weight, and a mile is a measure of distance. technically, a calorie indicates how much energy it takes to change the temperature of 1 gram of water by 1 degree celsius. this would make more sense if the body was made of ice, but nonetheless, this is what a calorie means.
the body needs energy (calories) to do anything. just how much depends on many factors, including what you do during a day (sleep all day, exercising, sitting at a desk, etc...). the average adult male needs between 2,000 and 3,000 calories a day. so if he eats this amount of energy a day, he would neither gain nor lose weight. he would be consuming as much as he uses. of course the amount of calories needed per day varies from person to person and day to do. so do your homework and please, pretty please, do not play the guessing game. too few or too many will not help you succeed in your weight loss goals!
since a calories is a unit of heat energy, your body sees calories as energy and it's energy to produce heat. heat energy is what really fuels our body, just the same way that gasoline is what fuels your car's energy.
now, all foods have calories and different foods have different amounts of calories. calories are provided by fat, carbohydrates, and protein.
fats have the highest concentration of calories. that's nine calories per gram of pure fat. protein and carbohydrates each have four calories per gram of pure protein or pure carbohydrate. alcohol, pure alcohol, has seven calories per gram. so understanding the role of calories in your diet can help you balance your calories in with your calories out, and help you achieve weight loss/weight management goals.
now you can look at, find out the calories in foods by looking at the nutrition facts. these nutrition facts will all have the number of calories per serving and the portion size per serving. using these tools, you can help yourself estimate how many calories you're taking in per day!
eat clean. live lean. live better. live longer.
