Welcome once again to the FreeTrainers.com Tip of the Week! This week we will
take a closer look at why eating fats actually makes us fat. Most of us realize that this occurs,
yet little of us actually understand WHY? So let's get started!
The amount of energy a particular food has depends on the quantity of fat, carbohydrates, and
protein it contains. Food energy, both in its consumption and expenditure, is measured in terms of
calories. Foods are either made up of fats, protein, carbohydrates, or a combination. A food that
contains mostly fat will contain more than twice the calories than a food containing mostly
carbohydrates and/or protein. For example, compare a serving of low-fat yogurt to a serving of nonfat
yogurt--the low-fat yogurt has quite a few more calories than the nonfat variety because every gram
of fat has more than twice the calories of a gram of protein or carbohydrate. Fat contains 9 calories
per gram; protein and carbohydrates yield only four calories per gram. Therefore, it is important that
you move towards replacing foods high in fat with foods higher in protein and complex carbohydrates.
No more than 25 percent of your total calories should come from fat, fewer than 10 percent from
saturated fat, the most damaging form. A recent study of 23 lean men and 23 obese men found little
difference in the total number of calories each group consumed. But the obese men consumed, on average,
more than 33 percent of their total calories from fat, compared with 29 percent for the lean men.
Because the body converts dietary fat into body fat more easily than it converts protein and carbohydrates
into body fat, the obese men were storing more fat even though both groups consumed the same total
number of calories.
During the process of converting protein and carbohydrates to fat, your body uses them as energy
and burns more than a quarter of their calories; it takes more energy (calories "burned") to convert
carbohydrates and protein into body fat than it does to convert dietary fat into body fat. Thus, more
carbohydrate and protein calories are used and fewer are stored as fat. Dietary fat, on the other hand,
goes straight into storage, with very few calories being used. For example, John consumes 2,000 calories
a day of which 40 percent come from fat. If John replaces half of the fat calories (20 percent of total
calories) with calories coming from complex carbohydrates, less food will be converted to body fat even
though the total number of calories consumed has not changed.
It is important to note that when that 20 percent of the 2,000 calories from fat now comes from
carbohydrates (or protein), you consume a lot more food, since each gram of carbohydrate or protein
contains less than half as many calories per gram. Therefore, when you begin to decrease the amount of
fat in your diet and replace it with carbohydrates and protein, even if you still consume the same amount
of food as before, you will be consuming a lot fewer calories.
If dietary fat were easy to control, most "diets" would probably succeed. Even with the recent
explosion of low-fat and nonfat products, people generally still eat too much fat. The reason is simple:
We have grown up loving fat, and we are accustomed to its taste and texture. Although most people do not
usually crave fat as they do sugar or salty foods, we do have a strong taste preference for fat. Fat is
responsible for the flavor and texture of many of our favorite foods: meats, cheese, dressings, sauces,
creams, desserts, etc.
Because a high-fat diet increases fat storage and yields more than twice the amount of calories,
the most effective way to reduce body fat is to concentrate on reducing your daily fat intake. Even if
you do not consciously lower your total caloric intake, making the switch to a low-fat diet will most
likely result in fat loss. However, attempts to suddenly restrict high-fat foods when you still have a
strong preference for them causes feelings of deprivation which may, in turn, cause a higher intake of
fat than normal. Deprivation is part of the "diet" process, and one of the main reasons it is doomed to
fail. It is very important to make gradual, healthier changes to the foods you enjoy. Drastic changes
backfire. When people base their food choices on the number of calories consumed and a "foods allowed/not
allowed" list, the focus is on numbers rather than satiety and enjoyment of the foods' taste and texture.
This often negates any positive effect the original focus on choosing low-fat foods may have had. Simply
counting calories and grams of fat does not make for a permanent healthy lifestyle change. If tastes do
not shift to enjoying foods lower in fat, this quickly becomes too restrictive and normal eating habits
resume.
I'm not saying that you should avoid counting grams of fat altogether. The way to lower fat in your
diet is to become a fat-conscious eater--and this requires that you know the amount of fat in each food.
However, instead of counting fat grams and deciding if it is a "good food" or a "bad food," try to balance
the foods you are eating so that you average 25 percent or less of your total calories from fat each day.
It's okay to have a piece or two of high-fat pizza (pizza can be low-fat) if you are truly hungry and
craving it, as long as you balance that out with low-fat foods at other meals soon after. What's crucial
is to learn how to make small healthier changes. Consume fat in moderation by balancing higher fat foods
with lower fat foods.
You should now have a better understanding of fat and why excess consumption of this nutrient makes
us fat. Your greatest challenge, however, is not learning new low-fat shopping or cooking techniques. Nor
is it remembering how to calculate fat percentages or what to say to the waiter to reduce the fat in your
restaurant meal. The greatest challenge facing you at this moment is deciding whether you are willing to
make a change--to make small, gradual changes to the foods you love.
Sure, there is plenty of work to be done, but it really doesn't matter how long this new process
takes. If you allow changes to take place over several years, your body will adjust comfortably, and you
will be more likely to maintain the healthy lifestyle permanently. When you begin achieving improvements
in energy and physical and psychological performance, the fun and excitement you experience will make the
change well worth the effort. Action creates motivation! Good luck: I hope you enjoy all the wonderful
benefits of a healthy, active lifestyle.
