Whey burns in your system 5 to 10 minutes.
Casein takes 2 to 7 hours depending on the person consumming. I know this is Marketing...but the following is directly from the CytoSport (makers of
Muscle milk's) site. ...
Leading scientists assessing the true role of fats in increasing lean muscle growth have shown all fats are not created equal. The type of fat determines whether you use it for muscle energy or store it as body fat! The LeanLipids™ used in Muscle Milk® promote fat loss three ways:
* Medium Chain Triglycerides (MCTs), the predigested “fast burning fats,” are more likely burned for muscle energy and heat than stored as fat. 20% of Muscle Milk lipids are MCTs.
* Long-chain polyunsaturated fatty acids are also less likely to be stored as fat. Special enzyme engineering makes these lipids even more functional, promoting anti-inflammatory effects and enhanced mineral retention.
* Recent research reveals calories with engineered lipids taken before and during workouts promote leanness. It is thought that these calories are used for workout energy, with less deposited as fat.
So, while Muscle Milk may contain slightly more fat than low-fat high-carb products, our Lean Lipids™ are designed to help you get leaner.
EvoPro™—Nature’s Ultimate Protein—Amino Blend
Human milk is composed of unique and highly complex proteins, peptides and amino acids, which promote rapid muscle tissue growth. EvoPro™ includes these alpha and beta micellar caseins, alpha-lactalbumin, lactoferrin, L-glutamine and more. Nature created this precise mix to stimulate muscle growth to higher levels, and EvoPro is the ultimate nitrogen delivery source.
Muscle Milk helps grow muscle faster than gainers, whey or even creatine. This increased muscle growth is possible because Muscle Milk is the first product patterned after Nature’s ultimate anabolic food—human mother’s milk. Locked within the composition of human mother’s milk are long-held secrets to muscle growth potential. We took the next step and actually duplicated these important muscle growth factors into Muscle Milk. Muscle Milk helps you grow muscle like never before.
Why would a product that says on the bottle (LOSE FAT...DON"T STORE IT!) have fat in it to make you fat?????????????????????
hehe. Definitely the best tasting protein shake out there.
tune in
