my retort is simply protein powder isn't real food. it isn't. if it was then zoo animals would be fed buckets of protein powder vs. real meat. they aren't. our bodies know the difference between a powder and REAL FOOD. if what you believe is true we would just need protein powder and veggie powders and we could just consume that all day. if you do that you WILL end up with major health problems because you cannot absorb much of anything from any sort of powder. you must eat REAL FOOD to get your vitamins, minerals, and protein.
protein powder is also very inflammatory, it will destroy your gut flora and cause you to absorb less from the actual food you eat. people who consume shakes every day are setting themselves backwards, not forward. and the worst thing of all is protein powders effect on recovery. your body has to use way more energy to digest a shake than real food. so instead of recovering properly you stunt recovery. how ironic that protein powder was pushed so hard the past 40 years to be consumed post workout when it actually is harming recovery. slow and hard to digest anything is the last thing you want to put in your body anywhere close to a workout or before bed. it makes absolutely zero sense, think about it!
