Burn That Fat!
One teaspoon of any type of oil, butter, or other
fat contains about 45 calories; in that sense, all fats
are equal. If you've been eating too many fat-laden foods
and have gained too much weight, you might consider dieting
and exercising to burn extra calories. This is
best accomplished by performing aerobic exerciseor
exercise that requires continuous, rhythmic contracting
of your large muscle groups. It also strengthens the most
important muscleyour heart. In addition, aerobic
exercise increases the "good" cholesterol (HDL-C) and
lowers triglycerides as well as blood sugar.
You need to burn off 3,500 calories
to lose 1 pound of fat. By walking 30 minutes 4 times
a week (for a total of 2 hours per week), you'll lose
a pound of fat in less than 6 weeks. This works out to
about 150 calories burned for every 30-minute walk. Activities
that burn slightly fewer calories in 30 minutes include
ballroom dancing (96 calories), yoga (100), and, yes,
sex (85). If you want to work a little harder, try running
a 9-minute mile (360), swimming at a slow pace (237),
cross-country skiing (222), hiking (214), tennis (204),
low-impact aerobic dancing (192), or cleaning the house
(114). |

All Fats Are Not Created Equal
A heart-healthy
dietone that reduces your risk of developing coronary heart
disease (CHD)consists of foods that help achieve or maintain
normal levels of cholesterol. These foods reduce overall
levels of low-density lipoprotein cholesterol (LDL-C), also known
as the "bad" cholesterol, or raise overall levels of high-density
lipoprotein cholesterol (HDL-C), the "good" cholesterol. Fats, like
cholesterol, can be good or bad. While your body does need some
fat for proper functioning, the trick is to choose foods with the
right kinds of fat and avoid foods with the wrong
kinds.
Types of Fat
Two types of fatpolyunsaturated fats and monounsaturated
fatscan normalize cholesterol and may be beneficial to
your heart. Two other typessaturated fats and trans
fatsraise LDL-C levels, which may be harmful to your heart.
Polyunsaturated fats are found in fish as well as in safflower,
sesame, soy, sunflower, corn, and cottonseed oils. Omega-3 fatty
acids, a special type of polyunsaturated fat that may play a major
role in preventing CHD, are found in many cold-water fish, such
as salmon, mackerel, and herring, and, to a lesser extent, in green
leafy vegetables, soybeans, nuts, and flaxseed and canola oils.
Polyunsaturated fats tend to help your body get rid of newly formed
cholesterol.
Monounsaturated fats are mostly present in olive, canola,
and peanut oils, in avocados, and in most nuts. If your diet is
very low in saturated fats but still your cholesterol readings are
unfavorable, monounsaturated fats may help reduce your LDL-C and
raise HDL-C. Some experts consider these the most desirable of all
the fats.
| Recommendations |
| On a typical day, the US adult eats a diet
made up of about 34% fat. Current recommendations are to reduce
fat intake to 30% or less of total daily calories. Saturated
fat should be limited to no more than 10%; the remaining 20%
should be equally distributed between polyunsaturated and monounsaturated.
Reducing daily fat intake is not a guarantee against developing
CHD, but it does help reduce your risk. |
Saturated fats are found mainly in animal products (eg, meat,
poultry, whole-milk dairy products, lard), but they are also in
certain vegetable products (eg, palm oil, coconut oil, cocoa butter).
Saturated fats in the diet increase LDL-C levels in the body, raising
your chances of developing CHD.
Trans fats are "partially hydrogenated" vegetable oils (also
known as trans-fatty acids). They are used in commercially
baked goods (eg, cookies, crackers, cakes) and in most restaurants
and fast-food chains. Those fries, onion rings, and doughnuts that
taste so good? They're usually made with trans fats. They are also
found in most stick, but not in liquid, margarines. Be aware that
labels on most of these products do not indicate whether they contain
trans fats. Instead, they state that the foods contain partially
hydrogenated oils, which should be avoided. Also, labels on products
containing trans fatswhich some experts consider worse than
saturated fats because they increase LDL-C and reduce HDL-Cmay
claim that they contain no cholesterol or saturated oils, but that
doesn't mean they're heart-healthy!
