Casein Vs. Whey For Dieting

Casein Vs. Whey For Dieting Dairy proteins are known for promoting a feeling of fullness that can help dieters and others who are watching what they eat resist snacking temptations. A study published in the Nutrition Journal compared the short-term satiety effect produced by casein, whey and other protein sources.

Researchers had 32 male volunteers in their mid-20s consume casein or whey either immediately before sitting down to a meal or 30 minutes earlier. Although whey was superior for lowering the blood glucose response to food consumption, casein reduced food intake 110% compared with the 62% caloric reduction experienced by subjects who had whey protein. The effect was most pronounced when the shake was consumed 30 minutes before a meal.

True Strength Moment: About 80% of a glass of milk is whey protein. The other 20% is casein. Whey digests much more quickly than casein, and its consistently is noticeably thinner than a rich creamy micellar casein shake. Both have their place in sports nutrition, and it appears that casein and whey can also provide different types of support to dieters.
