weight

 [wāt]
1. heaviness; the degree to which a body is drawn toward the earth by gravity. (See also Tables of Weights and Measures in the Appendix.) Abbreviated wt.
2. in statistics, the process of assigning greater importance to some observations than to others, or a mathematical factor used to apply such a process.
apothecaries' weight see apothecaries' system.
atomic weight the sum of the masses of the constituents of an atom, expressed in atomic mass units (or daltons), in SI units (i.e., kilograms), or as a dimensionless ratio derived by comparing the mass to the mass of an atom of carbon-12, which is taken as 12.000. Abbreviated At wt.
avoirdupois weight see avoirdupois system.
equivalent weight the amount of substance that combines with or displaces 8.0 g of oxygen (or 1.008 g of hydrogen), usually expressed in grams; for acid/base reactions, one equivalent donates or receives a mole of protons and the equivalent weight is the ratio of the molecular weight to the number of protons involved in the reaction. For oxidation-reduction reactions, one equivalent donates or receives a mole of electrons and the equivalent weight is the ratio of the molecular weight to the number of electrons involved in the reaction.
gram molecular weight the molecular weight of a substance expressed in grams; one gram molecular weight of a molecular substance contains one mole of molecules. See also mole1.
low birth weight (LBW) see under infant.
molecular weight the weight of a molecule of a chemical compound as compared with the weight of an atom of carbon-12; it is equal to the sum of the weights of its constituent atoms and is dimensionless. Abbreviated Mol wt or MW. Although widely used, the term is not technically correct; relative molecular mass is preferable.
very low birth weight (VLBW) see under infant.

weight

(wāt),
1. In scientific usage, the product of the force of gravity, defined internationally as 9.80665 m/s2, times the mass of the body.
2. In common usage, the apparent mass of a body when measured in air by comparison to standard masses of prescribed composition, the effects of the buoyancy of air being ignored.
3. A piece of material, usually metal, of known mass, used as a comparison object in weighing.
4. In statistics, a procedure to assign differential importance to certain observations at the expense of others, or a numerical factor employed in applying such a procedure.

weight

Physics The mass of a body multiplied by the force of gravity. See Atomic weight, Molecular weight Physiology The mass of a person, a measure of health. See Critical weight, Desirable weight, Extremely low birth weight, Healthy weight, Ideal body weight, Lean body weight, Low birth weight, Obesity, Overweight, Very low birth weight Statistics The relative importance of a datum.

weight

Patient discussion about weight

Q. I am uncomfortable with my weight. My very close friend who is out of my country is planning to come to my place next month. It is going to be our first meeting. I am uncomfortable with my weight. How Fast Can I Lose Weight?

A. A friend should accept you just the way you are. You should do the same.

Its just apprehension or anxiety from the first encounter. That's to be expected. Your friend is probably feeling the same kinds of things.

Q. What are good ways to loose weight?

A. diet and exercise,start a nutrional diet,eating fruits and veggies,stay away from fried foods,and remember to exercise,what ever exercise works best for you,diet with no exercise will leave you with flabby skin,

Q. how to lose weight without losing muscles

A. Exercise, especially one that increase the muscle mass of your body (i.e. weight lifting). In addition to the (relatively small) caloric expenditure during the exercise time itself, it's main effect is an increase in the BMR - the energy your body expends regularly, so you actually burn more calories during your daily life, even when not exercising.

Paradoxically, this will result in gaining (or not losing) weight, but with decrease in the body fat percentage, which means that the body lose fat and build muscle.

This kind of exercise is more suitable for men, since due to the lack of androgens women have much less potential to increase the muscle mass.

And of course remember you should consult your doctor before you start any exercise plan.
