No but you DON'T need more vits or minerals if you're taller. You do need more calories and possible more protein as you will have larger muscle areas, but the standard guidlines for vits and minerals are the same whatever your height and size. Your lifestyle might mean you need more of certain vits and mins - eg if you're a smoker or vegetarian, but not your height or size.
Sorry to be picky.
Equally I understand they have to have a cut off, but I also believe that half an inch shouldn't mean that someone is 'forced' to have an extra pack when they will function perfectly well on 3. 5'9" is going over so I agree by that point you do need 4, but why isn't there some graduation process starting at 5'7" up to 5'9" (for women) where between these heights you are advised that an extra pack might be beneficial, at 5'8" you are encouraged strongly to have it but it's not compulsory, up to 5'9" where you have to have the extra pack. Surely a CDC should be able to tell if someone contuinues to lose weight too quickly on 3 packs and they're 5'8" then they should be on 4 and they could be told this at the start??
I understand the guidelines are there, and I'm not denying it's important that they are, but surely this can be more flexible?? Why this cut off??
