Weight Loss & Health Benefits Diet should elicit a 500-1000 kcal per day deficit 1-2 lbs. lost per week deficit should be proportional the body weight Jakicic, J M ; Clark, K ; Coleman, E ; Donnelly, J E ; Foreyt, J ; Melanson, E ; Volek, J ; Volpe, S L.

Waist Circumference is linked to Mortality Relative Risk of Mortality was 1.36 times higher per 10% larger
waist circumference among men 1.30 times higher per 10% larger waist circumference higher among
women Biggard, J., Fredericksen, K., Tionneland, A., Thomsen, B. L., Overvad, K., Heitmann, B. L., & Sorensen, T. I. (2005). Waist circumference and body composition in relation to all-cause mortality in middle-aged men and women. Retrieved from http://www.ncbi.nlm.nih.gov/pubmed/15917857
ACSM Position Stand 2011 “Large prospective cohort studies of diverse populations
(216,237,320,353) clearly show that an energy expenditure of approximately 1000 kcal·wk-1 of moderate-intensity physical activity (or about 150 min·wk-1) is associated with lower rates of CVD and premature mortality.”
“An intriguing observation from several studies is that significant
risk reductions for CVD disease and premature mortality begin to be observed at volumes below these recommended targets, starting at about one-half of the recommended volume (i.e., ~500 kcal·wk-1) (214,237,320,353).”
