Those are mostly pretty basic concepts, but some of it is useless garbage. Burn more calories by reading than watching TV! How minor! These quacks tease you with a few tips and tell you if you buy the program, you will get all the secrets that no body else know on how to melt the fat away fast. Their are no secrets. When studies are done, the results are published. Do enough research outside of the commercial zone, and you find that the principles that are tried and true are simple and have been common pracitce for body builders for half a century. Okay, I see...you were just asking about #10. Drinking really cold water does cause the body to expend slightly more energy in order to keep your temp right, but it is very minor. Standing in the cold for 30 minutes would too. I wouldn't wait 30 extra minutes for breakfast and spend the time chugging water to spend a few extra calories. This stuff is too minor to be concerned with. These people selling these books or programs always throw in a few things most haven't heard off so you think their book is full of hundreds of little things that will transform you. If their top 10 tips didn't intrique you, would you buy their program? Cold water! You burn way more calories with a high fever. Maybe we should all try the flu.
