weight loss

a reduction in body weight. The loss may be the result of a change in diet or life-style or a febrile disease. To lose 1 pound a week a person must consume 500 fewer calories daily and/or expend 500 more calories daily through physical activity. See also wasting.

weight loss

A measurable decline in body weight (BW) either intentionally or from malnutrition or illness. It is considered mild when 5% of BW is lost, moderate when 5-10% of BW is lost, and high when more than 10% of BW is lost.

Patient care

Intentional weight loss achieved through dieting and/or exercise has significant health benefits for the overweight or obese. It reduces the risk of many common illnesses, including coronary artery disease, type 2 diabetes mellitus, hyperlipidemia, and hypertension. Unintentional weight loss, esp. of more than 10% of BW may be a marker of serious disease, such as AIDS, cancer, depression, hyperthyroidism, parasitosis, peptic ulceration, or food insecurity (starvation due to an inadequate food supply).

In the absence of scales the weights of large animals are often estimated on the basis of their age and their girth just behind the elbow. Called also liveweight. See also body condition score.
body weight-to-surface area

metric weight
see Tables 4.1 and 4.2.
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. Abbreviated mol. wt. See also Table 6.

Patient discussion about weight loss

Q. weightloss

A. what is the question...?

Q. How do i lose weight?

A. I think that the key to weight loss is not so much as dieting but taking control over what and how much you eat. I eat at least six times a day, thats four meals and two snacks. The protions that i eat however are not that big. I mostly just eat until I'm full or just satisfied. I really dont excercise either except for walking and I have lost 55 pounds over about a 3 or 4 month period. I LOVE food and the few diets that i did try didnt work, either because I was still hungry or I just didnt stick to them long enough to see results. I don't know if this works for everyone, but it worked for me. I think this worked because eating six meals a day kept my metabolism running almost constantly, so i ended up burning more calories than i took in. This may not take the weight off fast, but it can help you lose weight and keep it off. Hope this helps.

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.
