Intervention type: BEHAVIORAL
Group type: EXPERIMENTAL
Intervention: Exercise - Aerobic and Resistance
Description: Subjects will perform exercise (aerobic and resistance) 7d/wk and will exercise supervised 5d/wk. Exercise will be carried out to expend 250 kcals/day. Supervised resistance training sessions will take place 2 days/wk and aerobic exercise will take place every day. During the resistance exercise sessions, subjects will engage in a circuit weightlifting routine using guided motion machines. During the aerobic sessions, subjects may choose whatever exercise modality they like (e.g. walking on track or treadmill, biking, elliptical, etc.). Subjects will wear devices that measure energy expenditure to get a better idea of the intensity and duration needed to expend 250 kcals with their exercise machine/modality of choice.

Intervention: Dietary - Caloric Restriction
Description: Subjects will be counselled on their respective hypocaloric diets during the 16 wk period. Adherence to the prescribed diet will be assessed via collection of assigned food records (biweekly), frequent contact with subjects, and regular dietary counseling sessions. The daily dietary energy deficit will be 500 kcal per day based on the subjects' estimated daily caloric requirements (based on height, weight, age, sex), multiplied by a sedentary activity factor.~Additionally, subjects will consume 2 drinks per day that will differ depending on their randomization allocation. Subjects in the Dairy Protein and High Dairy Protein group will be provided with dairy products (e.g. milk, cheese, yogurt) to consume on a weekly basis to help facilitate their prescribed dairy and dietary protein intake.
