Understanding Calories, Fats, Carbs, and Proteins
A calorie is a unit expressing the potential energy in a food. Everyone needs a different amount of calories in their day to support metabolic activities. If you have more calories than it takes to support those activities, it will convert to fat. If you don’t have enough, it will burn fat for those calories, which will make you lose fat. Metabolic activities include EVERYTHING you do, sitting, breathing, playing sports, walking, pumping blood through your veins, sleeping, EVERYTHING YOU DO USES CALORIES!
Most healthy food is low-calorie. You’d be really surprised with how much more healthy food you can eat to equal the amount of calories as high-calorie foods. A handful of chips, slice of pizza, and candy bar equals about the same amount of calories as a 4 oz grilled chicken breast, apple, 15 baby carrots, one and a half slices of whole wheat bread, box of raisins, a cup of skim milk, and a granola bar. And those are all healthy calories – not empty calories.
The amount of calories somebody needs a day depends on your basal metabolic rate, degree of muscular activity, and rate of growth. Your basal metabolic rate (BMR) measures the rate at which a body expends under basal conditions like being at rest or in a calm and controlled environment. The average adult BMR requirement is about 1 calorie of energy per hour for each kilogram of body weight. But a person’s sex, size, body temperature, age, and endocrine gland activity are all factors that may change a person’s BMR.
3,500 excess calories can be stored as 1 lb of fat. When you deprive yourself of 3,500 calories you lose 1 lb of fat. So if everyday you give up 500 calories, it will take you 7 days to lose 1 lb. On commercials, these people say they lost 7 lbs in one week. This is physically impossible unless you need 3,500 calories a day and you don’t eat 1 thing. Don’t buy into these fake commercials.
Calories Used to Various Activities:

Walking upstairs 1,100
Running (jogging) 570
Swimming 500
Vigorous Exercise 450
Slow Walking 200
Dressing and Undressing 118
Sitting at Rest 100
Fats
It’s no wonder people blame their weight on high-fat foods, because 9 calories is in 1 gram of it! But you need a little to have healthy skin and hair. Too many will lead to heart disease and increase in cholesterol.
There are good fats and bad fats. Monosaturated fats, or unsaturated fats are the good fats in avocados and olives that promote a healthy heart. The help against heart disease.
But saturated fats contribute to cholesterol and heart problems. It’s mostly in animal products like milk, cheese, ice cream, beef, pork, and chicken. But the amount varies greatly. Like ribs might have 12g saturated fat per 4 oz serving and 2g in a roasted pork tenderloin 4 oz serving.
Fatty acids in meats like red meat are high in Omega-6, which isn’t as good as the fatty acids in fish which are high in Omega-3. But fish are generally low-fat and low-carb and all-protein when not breaded and fried.
Trans fat is just as bad as saturated fats. They clog up your arteries. They’re created through hydrogenation, which is a process that turns liquid oils to solids like margarine and shortening. This makes pie crusts flakier and fries crispier.
Some very high-fat foods are hamburger, nuts, plant oil, whole milk, butter, olives, avocado, and hot dogs.
I recommend 15-30 grams a day on my diet. It is VERY easy to eat low-fat! There are all sorts of fat free and low-fat products now-a-days. But if your not trying to lose weight, an average American should get about 30% of their calories from fat.
Fat is flavorful, and it makes our food taste good. But there is lots of other things to flavor your food other than fat. Herbs, spices, seasonings, and vegetables are few of many.
Carbs
In 1 gram of carbs, is 4 calories. Carbs are ENERGY! And without ENERGY you become WEAK! Which is why I believe low-carb diets are BOGUS! It is too hard to do and you are too weak and hungry. I have tried it and you feel awful. It can also lead to passing out from your kidneys not getting enough carbohydrates in about 1 month.
Carbs should make up about 60% of your calorie intake. There are two different kinds of carbs. Simple carbs and Complex carbs.
Simple carbs are simple sugars. The only kind of simple sugars you should try eat are in fruits, vegetables, and milk. Simple carbs are the kind of carbs you would find in a sugar bowl or an apple. The reason choosing the sugars in a fruit or glass of milk is better is because instead of just straight sugar you are getting fiber, vitamins, and minerals in an apple and you are getting proteins and calcium in milk. Calcium is important to get until you are 20 years old because your body collects as much calcium as it can until you are that age, so you will have healthier bones as an adult. So pack up on calcium when you’re young to have healthier bones! If you don’t like milk then chew 2 Tums tablets everyday. That is more than enough calcium. Simple sugars are junk so they will make you fatter. I recommend no more than 18 grams of sugars a day.
Complex carbs are also known as starches. They are a better choice over simple carbs. Starches are simple carbs in a LONNNNG chain. So they take longer to break down in your body. Starches are grain products like wheat, rice, crackers, pasta, rice, and oats. Choosing wheat over white bread is a great choice because the wheat bread has fiber and all sorts of nutrients. White bread has been processed, which means its been stripped from all that good fiber. Half of the carbs you get in a day should be whole-grain. The fiber in whole-grain foods like wheat bread, oatmeal, brown rice, and whole-grain flour will keep you fuller than white bread, white rice, and white flour. This is because the fiber in it takes longer to digest than no fiber. So even though a donut and a bowl of oatmeal may have equal calories depending on what you add to the bowl of oatmeal, the bowl of oatmeal will keep you fuller longer. Why? Because the more fiber you get the more calories your body burns trying to burn off the food.
Proteins
Like carbs, in 1 gram of protein is 4 calories. Proteins are what makes you grow and they are what makes your body stronger to fight infection. They also keep you full for a while. A piece of lean meat about the size of your hand should be enough protein for a day. You can also find out how many grams you need buy multiplying .04 by your body weight (lbs.) If your active you might need a little bit more. See if you’re a protein over-eater or under-eater.
Proteins contain important amino acids, which repair your body and produce red blood cells, enzymes, and other tissue.
Proteins can make you fat too. Think about making a necklace with beads. You have 12 yellow beads, 7 red beads, and 9 blue beads. You are making a pattern of yellow, red, then blue. Eventually you will run out of red beads and you’ll have 5 leftover yellow ones and 2 leftover blues.
Well your body works the exact same way. Different foods have different proteins. And you body uses the proteins to put in a pattern to build your body. But the leftover ones turn to waste until they can be used again whenever you have more of ones that you need to keep the chain going. Makes sense? The food that almost has no leftover proteins are eggs. 15-20% of your calories should come from protein.
The best place to get protein is in lean meats, but if you are vegetarian you are missing out on a lot! Getting enough protein as a vegetarian the low-fat way can be pretty tricky! Nuts and eggs both have protein but you get a lot of fat from them. And beans will have a lot of protein but you’ll also get a lot of carbs from them.

TIPS:
The first step to a successful diet is motivation. It’s not easy giving up eating yummy foods. But you need to make a decision.
Would you rather loose weight, or keep eating the way you do?
1. Keep a journal. Date it. Whenever you wake up in the morning, write down what you ate, when you ate, whom you ate with, where you ate at, etc. And most importantly, the calorie content of the meal. Always count your calories!! And counting your carbs, proteins, and fats along with that is even better! Make sure right when you eat, you write it down in your journal.
2. Be specific! Instead of writing “bowl of cereal” write: 1 cup of Cheerios with ¾ cup of skim milk. When you eat a sandwich, make sure you include how many slices of meat were on it, the bread, mustard, mayo, and cheese. All of these things can add many calories to your meal.
3. Make a list of all the reasons you want to lose weight and keep in the front of your special journal. Make sure the list is 15 reasons long at least. And every time you want to indulge in a piece of cake or slice of pizza, read that list. Look in the mirror. Look at a picture of celebrity with a nice body.
4. It’s hard to keep a journal and to count your calories all by yourself. That’s a lot to think about and is a big headache. There is this wonderful website on the Internet called Fitday where it will count your calories, fats, carbs, and proteins for you! I used it for my journal and I highly recommend it. It has a part on it for exercise, food, your weight-loss, your goal, and even a journal to write down how you felt about the day. It’s www.fitday.com. Visit it! Another awesome one which is even better than fitday is www.myfitnesspal.com.
5. Count your calories before you eat them. That way you know what you are putting in your body. An even better idea is whenever you wake up; plan everything you will eat to equal exactly how many calories you plan on taking in. Write it on a piece of paper and keep it in your pocket so you remember what to eat.
6. Write a list of all the bad things you do that you used to do. That you will NEVER go back to doing. Like my bad habits were I would go through an ENTIRE bag of Pizza Combos, which is like 900 calories in 1 sitting. I would drink almost 6 cans of soda a day. I’d have a chocolate milkshake every night before I went to bed. I’d fill my plate 4-5 times at the all you can eat buffet. Read it over and over! Turn yourself off about unhealthy food.
Good luck!!
