without creating a shit disturbance, i must point out that peanut butter or any other food has NO IMPACT on the absorption rates of amino acids/ peptides from whatever protein source that was ingested. FAts and Carbs are brought into your system via other pathways that that of protein and thus do not compete/impede the progress of the protein breakdown in any way. what the fats may do is increase/decrease transit time depending on how much is eaten but this has nothing to do with protein. fats also increast the sense of satiety. so you may go longer periods of time without eating. they also may increase the amount of free fatty acids in your bloodstream thereby reducing the need of your body to tap into your protein stores ( muscle)
night time a slower acting protein would be fine, as everyone has stated. after/before a workout a faster digesting protein like whey would be better. if you eat every 2-3 hours, it doesn't make a difference.
if you can handle the carbs,then put skim milk powder in with your whey protein throughout the day. or if the carbs are a no go, then get a milk protein ( sodium caseinate seems to be better than calcium caseinate ) or milk and egg protein to mix with the whey. if you are going to go long times between meals, stick to the caseinates.
sometimes people talk of whey blends when they actually mean whey concentrate; not that the protein is a blend of whey, casein and egg or whatever. Prolab pure whey is a whey concentrate product- not much of the protein is broken down. Unlike other protein products whose protein is derived from fractionates of the whey, such as designer. this is true ifyou believe the labels and the advertising.
blended protein products of whey, casein and albumin would be good if you are going to go longer periods between meals.
it doesn't matter to me as i eat every couple of hours.
