Weight loss refers to the loss of total body mass in an effort to improve fitness, health, and/or appearance.
Therapeutic weight loss, in individuals who are overweight or obese, can decrease the
likelihood of developing diseases such as diabetes, heart disease, high blood pressure,
stroke, osteoarthritis, and certain types of cancer.
Weight loss occurs when an individual is in a state of negative energy balance. When the human body is spending more energy in work and heat than it is gaining from food or other nutritional supplements, it will use stored reserves of fat or muscle.
Although weight loss may involve loss of fat, muscle or fluid, weight loss for the purposes of maintaining health should aim to lose fat while conserving muscle and fluid.
When you stand on the weighing scales, it is nice to see you lost that undesirable weight. But how do you know you have lost it from FAT and not just from fluids or even worse from muscles, which will make you lose less fat.
Others might go on the scales in hope they have gained weight, hopefully from MUSCLE, not fat. But how do you know all these answers?
Unfortunately you won't,
unless you are properly assessed!
