Does it matter when you take your whey protein throughout the day?
It depends on your goal. If you're looking to build some muscle rather than lose fat, it may not be important. If you have a significant amount of weight to lose and you are concerned with insulin sensitivity, it may be a better idea to save the whey until pre and post workout. Whey promotes an insulin spike similar to that of white bread (very high). This would be beneficial around the workout, but not so much during other times when you are sedentary. As for just consuming protein in other forms (meat, eggs, dairy, etc.) the timing is not as relevant, but depending on your goal, the timing of whey protein may be significant.
