1)What is the purpose of fats?
- To release hormones that control metabolism
Fat is known to have two main purposes:
-Fat stores excess calories in a safe way so you can use them when you're hungry, and
-Fat releases hormones that control metabolism.
- 9 calories
The number of calories you need each day varies depending on your body size and activity levels. Someone who needs about 2,000 calories a day should eat no more than 65 grams of fat a day on average. To determine your ideal daily dietary fat intake:
1. Take the number of calories you eat each day and multiply it by 30 percent (.30). For example: 2,000 calories x .30 = 600 calories from fat.
2. Divide your answer by 9 because there are 9 calories in each gram of fat. This will give you the number of grams of fat per day that should be your upper limit goal. Here, it's: 600 / 9 = 65 grams.
A person who gets 2,000 calories per day ideally should not consume more than 65 grams of fat. Some researchers suggest that even 65 grams of fat in a 2,000 calorie diet is still too much fat.
3) Belly fat is worse than hip/thigh fats
Abdominal, or belly, fat is viewed as a bigger health risk than hip or thigh fat. It has a worse effect on insulin resistance, boosting the risk of diabetes, and a worse effect on the level of fats in the blood, boosting heart and stroke risks. Belly fat, or an apple-shaped body, is also most associated with heart disease and other diseases, such as metabolic syndrome and type 2 diabetes. The bigger your waist, the higher your risk of developing heart failure, a condition where the heart isn’t pumping enough blood out and fluid begins to back up into the lungs and/or pool in the feet and legs
4) What is Brown fat?
-Brown fat = Baby fat
Brown adipose tissue (or brown fat) is a rapid source of energy for infants and forms about 5% of their body weight. It is brown because the cells in it are packed full of small cellular organs called mitochondria, which are energy factories, and it has a rich supply of blood vessels. Brown fat is virtually gone by adulthood.
5) The normal percentage of body fat for a women is: 25%-30%
the normal amount of body fat (expressed as a percentage of body weight) is between 25%-30% in women and 18%-23% in men. Women with over 30% body fat and men with over 23% body fat are considered obese.
6) One pound of fat = 3,500 calories
There are 3,500 calories in a pound of fat. You need to burn off 3,500 calories more than you take in to lose 1 pound. This translates into 500 calories per day to lose 1 pound in a week, or 1,000 calories per day to lose 2 pounds in a week. (1-2 pounds per week is generally considered to be a safe rate of weight loss). This can be achieved by eating fewer calories or using up more through physical activity. A combination of both is best.
7) Fats maintain healthy hair and skin
Believe it or not, healthy skin and hair are maintained by fat. Fat helps the body absorb and move the vitamins A, D, E, and K through the bloodstream.
8) What is hyperlipidemia?
-High fat in the blood
Hyperlipidemia describes high fat content in the blood. High blood cholesterol that runs in families, called familial hypercholesterolemia, is the most common inherited type of hyperlipidemia. It predisposes those who have it to premature hardening of the arteries including coronary artery disease with heart attacks at an unusually young age. About half of men and a third of women with these conditions suffer a heart attack by age 60.
9) When a product contains partially hydrogenated vegetable oil, what does the term "hydrogenated" mean?
Hydrogen was added to the oilDuring this process called hydrogenation, hydrogen is added to vegetable oil. Hydrogenation turns a liquid fat such as vegetable oil into a semi-solid (harder), more shelf-stable fat, such as margarine. Most oils are only partially hydrogenated, which creates harmful trans fats that can raise cholesterol.
10) Why would food manufacturers add hydrogen to vegetable oil?
Surprised? It's true; the more weight you carry, the faster your metabolism is likely running. "The simple fact is that the extra weight causes your body to work harder just to sustain itself at rest, so in most instances, the metabolism is always running a bit faster," says Molly Kimball, RD, sports and lifestyle nutritionist at the Oscher's Clinic's Elmwood Fitness Center.
That's one reason it's almost always easier to lose weight at the start of a diet and harder later on. Kimball says: "When you are very overweight, your metabolism is already running so high that any small cut in calories will result in an immediate loss."
