- InterventionsDuration of intervention: 13 weeks.

1. Intervention group: All participants in the intervention group will receive 10 servings a week of the Active study product, which has a high protein content;
2. Control group: All participants in the control group will receive 10 servings a week of the (isocaloric) Control product.

Both products consist of about 40 grams of powder which has to be dissolved in 125 ml of water and are available in two flavors: vanilla and strawberry.

During the intervention period, subjects consume one serving a day, and on training days one extra (3 days per week).

Both groups will be enrolled in a hypo-caloric weight loss diet and participate in a resistance exercise program comprising 3 supervised group sessions per week at the study centre.
- Primary outcomeChange in appendicular muscle mass (DXA).
- Secondary outcome1. Body composition (BodPod, BIA);
2. Muscle strength (hand-grip, leg-extension);
3. physical functioning (chair stand, gait speed, 400m walking test);
4. Quality of Life (RAND-36 questionaire).
- Timepoints1. Baseline;
2. After 7 weeks;
3. After 13 weeks.
