You use a fast-acting protein like whey either before or after your
workout, depending on how your meal timing works out. You’ve heard how
casein proteins are beneficial right before bed, for longer lasting
anti-catabolic support when your muscles do the majority of their
recovering. Now a study published in the
American Journal of Clinical Nutrition suggests that casein may have another very promising application.
Researchers had 25 people consume either a diet split 25% casein
(protein), 55% carbohydrates and 20% fats or a 10%-55%-35% breakdown of
the same macronutrients. The 25% casein group enjoyed 33% greater
satiety while raising total energy expenditure 2.6% over the 10% casein
group. They also posted a higher sleeping metabolic rate, meaning they
burned more calories while snoozing.
The Bigger Picture: While getting a quarter of your
daily calories from casein might be a bit extreme, the results of this
study suggest that casein can be employed for
weight management. Its
ability to keep you feeling full (satiety) and metabolic boosting
qualities are reason enough to give it a try. That shake might make an
ideal between meals meal.
