Weight loss, in the context of medicine, health, or physical fitness, refers to a reduction of the total body mass, due to a mean loss of fluid, body fat or adipose tissue or lean mass, namely bone mineral deposits, muscle, tendon, and other connective tissue. Weight loss can either occur unintentionally due to malnourishment or an underlying disease or arise from a conscious effort to improve an actual or perceived overweight or obese state. "Unexplained" weight loss that is not caused by reduction in calorific intake or exercise is called cachexia and may be a symptom of a serious medical condition. Intentional weight loss is commonly referred to as slimming.
As we mentioned before the Venus Factor program contains a step-by-step workout program for 12 weeks which is divided into 3 phases of 4 weeks each. The great thing about the workout program is that it is not only contains easy to follow explanations but also useful pictures and great videos that will ensure you get the maximum benefit from each phase of workouts.
Lifestyle and work habits partially determine how many calories we need to eat each day. Someone whose job involves heavy physical labor will naturally burn more calories in a day than someone who sits at a desk most of the day (a sedentary job). For people who do not have jobs that require intense physical activity, exercise or increased physical activity can increase the number of calories burned.
The scientific soundness of commercial diets by commercial weight management organizations (CMWOs) varies widely, being previously non-evidence-based, so there is only limited evidence supporting their use, due notably to high attrition rates. Commercial diets result in modest weight loss in the long-term, with similar results regardless of the brand, and similarly to non-commercial diets and standard care. Comprehensive diet programs, providing counseling and targets for calorie intake, are more efficient than dieting without guidance ("self-help"), although the evidence is very limited. The NICE devised a set of essential criteria to be met by commercial weight management organizations to be approved.
For some people, due to genetic (inherited) factors or other health conditions, the resting metabolic rate (RMR) can be slightly higher or lower than average. Our weight also plays a role in determining how many calories we burn at rest -- the more calories are required to maintain your body in its present state, the greater your body weight. A 100-pound person requires less energy (food) to maintain body weight than a person who weighs 200 pounds.
