Dietary manipulation is proving to be an effective lifestyle strategy to combat the obesity epidemic. Increased dietary protein is one effective strategy. For example, increased whey protein ingestion with and without exercise training is associated with enhanced weight loss, body composition and subjective hunger in overweight and obese individuals. Our findings suggest that the effects of whey protein ingestion occur independent of a calorie-restricted diet and to a greater extent in individuals following a combined exercise program of resistance exercise, sprint intervals, stretching/yoga/pilates, and aerobic exercise training compared to standard resistance training.
This study was a 16 week whey protein and exercise training intervention in middle aged overweight/obese adults. Subjects were randomized into 3 groups: Whey protein only consumed as 20 grams per serving three times per day (total 60 grams per day) (WP); Whey protein and resistance exercise training (WP-RT); and Whey protein and combined exercise training (P+RISE). All outcomes, including the primary outcome of visceral fat was measured at baseline (week 0) and post-intervention (week 17) in all study subjects.

Estimate

Dietary Supplement Whey Protein

Whey protein provided in 20 gram servings administered three times per day. once in the morning upon waking; a second serving in the mid-afternoon; and a third serving within 2 hours of going to sleep at night.

Dietary Supplement Whey Protein and Resistance Exericse

Subjects will receive 20 grams of whey protein three times per day along with 4 days per week of resistance exercise training throughout the 16 week intervention.

Other Whey Protein and RISE exercise routine

Subjects will consume 20 grams of whey protein three times per day (total of 60 grams) and perform a combination of exercise involving functional resistance exercise (R); sprint intervals (I); stretching/pilates/yoga (S); and endurance exercise (E); RISE four days per week.

Whey Protein Only Active Comparator

Ingestion of whey protein only (20 grams per serving) consumed 3X/day along with ad libitum diet for a total of 60 grams per day. One serving was consumed within 1 hour of waking in the morning; a second serving was consumed mid-afternoon; and a third serving was consumed within 2 hours of going to sleep at night.

Whey Protein and Resistance Exericse Experimental

Ingestion of whey protein (20 grams per serving) 3X/day: one serving within an hour of waking in morning; a second serving mid-afternoon or within 1 hour immediately following a resistance exercise bout on exercise days; and a third serving within 2 hours of going to bed at night.

Whey Protein and RISE exercise routine Experimental

Ingestion of whey protein (20 gram serving) 3X/day: one serving within an hour of waking in the morning; a second serving mid-afternoon or within 1 hour immediately following the RISE exercise bout; and a third serving within 2 hours of going to bed at night.
