Diet"

Before we can start talking about diets and diet plans, you must first understand what a diet REALLY is and what it REALLY means. See, people tend to use the phrase "I'm on a diet" when they want to tell people that they are trying to lose weight. People who do this are... well... stupid. A diet IS NOT weight loss. Diets are just simply what you eat on a regular basis. You could eat McDonald's cheeseburgers covered in ice cream 4 times a day, and you'd still be "on a diet." While eating like this would certainly be the worst of all diet plans, you get my point.

If someone said, "that monkey's diet consists of bananas," would that mean the monkey has a weight problem? No, it would just mean that the monkey eats bananas on a regular basis. Saying you're on a diet really just means you eat food. That's why I think it's funny when people state that they're "on a diet" and expect it to mean something it doesn't. "You're on a diet? Wow... congratulations... so is EVERY OTHER LIVING THING ON THE PLANET!!" These people should be saying that out of the many different diets and plans that exist, they're "on a weight loss diet." Hopefully these people are reading this right now, and hopefully they have learned their lesson. It's ok, we forgive you.

Diet Plans For Different Goals

Now, chances are you ended up here for one of the following reasons:

A) Your goal is weight loss and losing fat.
Your goal is weight gain and increasing muscle.
C) Your goal is to lose fat AND increase muscle.


Which ever it is makes little difference at this point, because it all starts with your diet. You see, with the exception of a few small details, all diet plans are exactly the same. They all break down the same way. All diets consist of the same things. It's how you adjust those things that makes the difference between A, B and C. So, let's find out what exactly these "things" are.

Calories And Maintenance Levels

Now that you fully understand what diets are, let's break down what all diet plans consist of. Above all things, there are calories. All diets are made up of calories. Everything you eat and drink (besides obvious calorie-free things like water and celery, etc.) has calories in it. It's how many calories and exactly where those calories are coming from that effect your body and your weight. The way the human body works is pretty simple. There is a certain number of calories that your body requires every day in order for it to maintain its current weight. I like to call this your "Maintenance Level" because, well, that's what it's actually called. If your diet plan is made up of less calories than this maintenance level, you will lose weight. If it's made up of more calories, you will gain weight. It's all really simple, actually.

If you just read that last paragraph you should feel good about yourself. Why? Because right now you already know more about diets and nutrition than at least 80% of the population. No, you're no genius yet. It's just that most people are clueless about the subject of "diet plans" and how to actually control their body and weight.

So now that you know that diets are made up of calories, you should be wondering what exactly calories are made up of. Basically, calories are made up of 3 things. Protein, carbs, and fat. Yeah yeah, I know. High protein diet!! Low carb diet!! Low fat diet!! Healthy fat!! Fat free!! Good carbs!! Bad carbs!! Those are probably the assortment of confusing things that enter your mind as soon as you hear the words protein, carbs and fat. It's ok though, relax. In a few minutes none of it will be confusing ever again. Let's take them one at a time.

Protein

Protein is an extremely important part of all diet plans. That's why you have most likely never heard of any low protein diets, and also why you probably HAVE heard of protein supplements. That's because your body needs protein, and lots of it. It is the building block of muscle. Protein is measured by the gram. 1 gram of protein is equal to 4 calories. So, if you are eating something that has 20 grams of protein in it, that means that whatever you are eating is at least 80 calories. In case you failed 2nd grade math, that was 20 grams of protein multiplied by 4 calories per gram... 20 x 4 = 80

How much protein?

It is usually recommended that a person looking to increase muscle should be eating at least 1.5 grams of protein per pound of body weight. So if you weigh 200lbs, you should try to eat 300 grams of protein a day. That might sound impossible at first, but it is VERY doable and quite simple once you get used to it. This is also why they invented protein supplements. While the majority of my daily protein intake comes from actual foods that are high in protein, I use protein shakes and protein bars to supplement the rest. They are very helpful, and I recommend them.

Some high protein foods include:

Meat
Chicken
Turkey
Fish
Eggs (egg whites)
Nuts

Carbs

Carbs (or "carbohydrates" for the people who don't mind typing 8 extra letters) is another of the three main elements that make up calories. I have a feeling that of the three, carbs are the most confusing for people creating diet plans. I think the reason for that is because everything you enjoy eating has carbs in it. Hell, everything you don't enjoy eating has carbs in it. Carbs are in almost everything and therefore seem to be the hardest for people to manipulate within a diet plan. Just like protein, 1 gram of carbs is equal to 4 calories. So, if you were eating something that had 20 grams of protein and 10 grams of carbs, you just ate at least 120 calories (20x4=80, 10x4=40, 80+40=120calories).

How many carbs?

And that leaves carbs. You factored in that you need to eat 1 gram of protein per pound. So now do the math. Sticking with the 200lbs example, that means you are eating 300 grams of protein a day. 200x4 = 800 calories. So in this example, 800 calories of the daily calorie intake is accounted for from protein alone. You can now also factor in the 25% of your daily calorie total coming from fat. Once you factored in both the protein and fat, whatever number of calories you are left with... those will come from carbs. Got that? 1 gram per pound for protein, 25% of the total calorie intake is fat, and everything else should come from GOOD carbs.

Some foods containing "good" carbs include:

Oatmeal
100% whole wheat bread
Whole wheat pasta
Brown rice
Yams
Sweet potatoes
Beans
Green leafy vegetables



Fat

Unlike protein and carbs which are both 4 calories per gram, 1 gram of fat is equal to 9 calories. So if you eat something that has 10 grams of fat in it, you just ate at least 90 calories. This explains why high protein foods are usually low in calories, while foods high in fat are high in calories. This is also probably the reason why there are so many fat free foods and why people on diets think fat makes them fat. Guess what... it doesn't. That is a myth.

Fat does not make you fat. Eating too many calories makes you fat. It just so happens that a gram of fat has more calories in it than a gram of protein or carbs. However, the only thing that makes a person gain fat is when that person is eating more calories than their maintenance level, and then not burning them off through working out. Whether these excess calories in your diet plan are coming from protein, carbs or fat makes little difference.

Sometimes people on specific weight loss diet plans just try to eat less fat (or even fat free) and think that alone will work. What they don't realize is that they are probably replacing those fat calories with calories from protein or carbs. Yes their fat intake has become lower, but their calorie intake evens back out to what it was, if not more. And, since you now know that it is too much calories, NOT fat, that causes fat gain, the person's weight usually won't decrease.

How much fat?

For fat, I can't give you an exact number of grams. Instead I can give you a percent. Approximately 25% of you daily calorie intake should come from fat. It doesn't have to be EXACTLY 25%, but something in that range seems to be the ideal amount. And by fat of course, I mean GOOD fat.

Some foods containing "good" fat include:

Fish
Nuts and seeds
Olive oil
Flax seed oil


Different Diets And Plans

So now that you know diets consist of calories, and calories consist of protein, carbs and fat, you should have just one final 4-part question. Exactly how much protein, how much fat, how many carbs and how many calories should you be eating each day in your own diet plan? It's hard to answer this because there are 100's of different diets out there whose "gimmicks" revolve around the answers to those questions.

Especially when it comes to weight loss diets. There's the low carb diet, the low fat diet, the high protein diet, the atkins diet, the south beach diet, the zone diet, and too many others to even remember. While those diets have their place and some people like all of the gimmicky aspects of them, honestly... none are truly needed. If one seems ideal for you, then by all means, use it.

Most people know that a diet low in saturated fat, cholesterol and sodium is better for their heart and overall health. But few people understand why. Even fewer know what quantities of these substances actually qualify as "low" or healthy.

It's especially important for people with heart failure and other heart conditions to understand the terms associated with a "heart-healthy" diet. This section will help you learn what saturated fat, cholesterol and sodium are; where we get them; why too much is unhealthy; and what the recommended limits are.

Fat

What It Is: Fatty acids are found in plants and animals and are essential for the body's proper growth and functioning. There are three kinds of fats in the foods we eat: saturated, polyunsaturated and monounsaturated. Saturated fats are usually solid at room temperature, while polyunsaturated and monounsaturated fats are liquid at room temperature. Polyunsaturated oil is liquid at all temperatures. Trans-unsaturated fatty acids are found in hydrogenated and partially hydrogenated oils and some animal products.

Where We Get It: Most foods contain all three types of fat, but in varying amounts. We mainly get saturated fats by eating animal foods such as beef, beef fat, veal, lamb, pork, lard, poultry fat, butter, cream, whole milk, cheeses and other whole-milk dairy products. Coconut, palm and palm kernel oils are also high in saturated fat. Trans fat, which comes primarily from hydrogenated fat, acts as saturated fat in the body. We get unsaturated fats mainly through vegetable oils. Polyunsaturated fats are found in safflower, sunflower, corn and soybean oils. Monounsaturated fats are found in canola and olive oils.

Why Too Much Is Unhealthy: Eating too much saturated fat can raise your blood cholesterol level, which increases the risk of coronary artery disease (clogged arteries) and heart attack. In moderation, unsaturated fats may actually help to reduce blood cholesterol, especially when substituted for saturated fats. However, it's important to control total fat intake because fats have more than twice as many calories as protein and carbohydrates.

Recommended Limits: The average person should adjust their total fat intake to meet their caloric needs. Diets for weight reduction should contain no more than 30 percent of total fat. (Daily calorie intake depends on gender, height and weight. A doctor or registered dietitian can make recommendations for you.) Of that amount, no more than 7 to 10 percent should be saturated fat and up to 25 percent unsaturated fat. The table below converts these values into grams to make it easier to read food labels or use a nutrition counter.

*Note that the American Heart Association recommends lower amounts of saturated fat (less than 7 percent of total calories) for people with heart failure or high cholesterol levels.

Daily Calorie Intake...............Total Fat (grams)...............Saturated Fat (grams)
1,200 .....................................40 or less .............................11–13
1,500 .....................................50 or less .............................13–17
1,800 .....................................60 or less .............................16–20
2,000 .....................................67 or less .............................18–22
2,200 .....................................73 or less .............................20–24
2,500 .....................................83 or less .............................22–28
3,000 ....................................100 or less .............................27–33

Cholesterol

What It Is: Cholesterol is a soft, waxy, fat-like substance in your bloodstream and in all your body's cells. It's used to form cell membranes, some hormones and other tissues.

Where We Get It: Our bodies produce cholesterol, mainly in the liver. Foods high in saturated fat and cholesterol — such as meats, poultry, fish and dairy products — can raise your blood cholesterol levels, too.

Why Too Much Is Unhealthy: When blood cholesterol levels are high, cholesterol and other fatty substances are more likely to collect in the inner walls of blood vessels. Eventually, these deposits can restrict or even block blood flow to the heart. This buildup is associated with developing coronary artery disease, which can lead to heart attacks.

Recommended Limits: The average person should consume less than 300 milligrams of cholesterol per day. People with a heart condition or who have high cholesterol levels may need to limit their intake to less than 200 milligrams. They should check with their doctor.


Sodium

What It Is: A mineral necessary in small amounts for many body processes.

Where We Get It: We consume most of our sodium in the form of salt, which is made up of sodium and chloride. High-sodium foods include cheeses, lunch meats, cured meats, breads, cereals, prepared foods like canned and frozen products, and baked goods made with baking soda or baking powder.

Why Too Much Is Unhealthy: In some people, too much sodium causes blood pressure to rise. High blood pressure constricts the arterioles, making them resistant to blood flow. This makes the heart work progressively harder to pump enough blood to the body's tissues and organs. High sodium levels also cause the body to retain fluid, which increases the heart's workload. People with heart failure and other heart conditions need to be especially careful not to put this extra strain on their heart.

Recommended Limits: Most people should limit daily sodium intake to no more than 2,300 milligrams.

Very informative article. I like how you broke down macro's and explained how caloric intake excess over maintainance levels leads to fat increase.

Keep up the good work!
