Regarding weight loss, it really just comes down to calories in < calories out, though longer rest breaks could possibly help, if it means prolonging the workout and keeping your heart rate up for a longer period of time. (health reasons aside for possibly needing longer breaks, I'm just talking weight) If that ends up helping, thats all it would be, is that you are basically "exercising" for a longer period of time, not that the break itself is magically making you lose weight faster. You may want to keep a food diary or something to see exactly, after a week or two, what you are taking in, how many calories it is, etc. NFL linemen work out like madmen too, but they don't lose weight because, by design, they eat like madmen.
