Fat
Macronutrient that is a source for long term energy and energy storage (as adipose tissue); necessary for absorption and transport of fat-soluble vitamins and constituant of hormones and cell membranes.
One gram of fat equals nine calories. There are 455 grams in one pound. So nine calories times 455 grams equals 4,025 calories per pound of fat. So, technically, you need to lose 4,025 calories to lose one pound of fat.
Fiber
The more insoluble the fiber is (fiber that does not dissolve in water), the better it is for you. Insoluble fiber reduces the risk of colon cancer and high blood pressure. Fruit fiber seems to be more beneficial then vegetable or cereal fibers, probably because fruits are loaded with Pectin, an insoluble fiber. As a rule, the higher the insolubility, the fewer the calories. Corn bran is the best, followed by wheat bran, and then oat bran. It is best to eat fiber after you work out to avoid intestinal discomfort.
An enzyme known as 5-alpha reductase, acts upon testosterone, converting it to a hormone called di-hydro-testosterone (DHT). It is believed that high levels of DHT are a contributory factor in the enlargement of the male prostate, which can lead to the formation of prostate cancer. It is certainly clear that DHT levels rise as men get older. This condition is known as Benign Prostate Hypertrophy (BPH).
Finasteride belongs to a group of drugs known as 5-alpha reductase inhibitors. By blocking the action of 5-alpha reductase, Finasteride reduces levels of DHT. Consequently, use of Finasteride has been shown to decrease the size of the male prostate. The most common brand name for Finasteride as a prostate treatment is Proscar.
High DHT levels have also been cited as being a contributory factor in the development of male pattern baldness, and the increased growth of body hair. The use of Finasteride on a regular basis has been shown to help reduce male pattern baldness and slow the development of body hair. The most common brand name for this application is Propecia.
Flavinoids
A group of compounds widely distributed in plants which have a characteristic molecular structure. They have been found to have many beneficial activities, such as anti-inflammatory and anti-carcinogenic properties.
Flaxseed Oil
Flaxseed is an excellent source of the omega-3 fatty acid alpha-linolenic acid (an EFA). Supplementing with flaxseed oil has been shown to lower cholesterol, decrease heart disease, increase satiety and improve cell integrity.
Free Radicals
Free radicals are highly reactive molecules in the body which can destroy tissues by oxidizing cell membrane lipids and damaging DNA, the body's genetic material. Free radicals are produced through the body's normal process of metabolizing the air we breath and the food we eat, as well as exposure to tobacco smoke, excess sunlight and environmental pollutants. Antioxidants work in the body by neutralizing free radicals before the can do significant harm.
Flouxymesterone
Fluoxymesterone, an androgenic hormone, is similar to the male hormone testosterone. It is primarily prescribed as an adjunct to Testosterone Therapy; keeping the dosage of testosterone lower, to avoid unwanted side affects.
