that advice is the whackness. first off, are you weight-training? what's the workout? if you're weight training, do eat carbs with your protein. frankly, i don't think it's such a big deal to mix in fat too, but if you're being conscious of overall caloric intake, it may be prudent to limit the fat. but carbs and protein should be your priority after weight training, regardless of your body fat percentage.
"dean ornish and dr. davis think the palmitic acid our bodies use for fuel while we sleep is poison if we eat it. zero-carbers like charles washington think the oldest fuel in our evolutionary history – glucose - used by organisms a billion years ago and without which the brains of modern mammals cannot survive for more than a few minutes – is an unnatural toxin if you eat it. both views ignore basic facts of medical physiology and defy evolutionary history." - kurt harris
