Doing the ultimate detox in 7 days, instead of 14..

Can I do the Ultimate detox in 7 days? I have done the detox once before, opting for the 14 day intensive program, and it was great! I want to do it again, however as an athlete competing weekly – I do not have the 14 days off (required if doing the 14 day program) to commit to this program. I was thinking I might be able to ramp it up by doing the 3-days of preparation followed by 7 days of taking the pills. Will this be ok? And if so, should I just follow the 14 day diet plan (for 7 days) or will that need to be adjusted too? Regards,
