T-Dawg Calories

My wife and I are starting the t-dawg diet and it states that you multiply your weight by 15. Is that true? I’m 6’4" and 260lbs that is 3900 cal. That makes me very nervous. I don’t know if I can get that many calories in a day. And only 100 of them are carbs on training day. Do the rest come from proteins and fats? Any suggestions or advise is welcome.

Thanks
