I drink 4.5 liters so I am always optimally hydrated, and in truth its not that much. I live in a smoggy city with humidity so I'm always sweating.
Calorie intake is around 1400-1800 a day.
The meals arent that hard to cook, toss veggies etc into boiling water done in 3 min. Meats etc done in 5 min on grill.
I eat my first meal at around noon and finish off at around 2 am with my last. I have 4 months off school and I don't work so I can follow this diet fully. Normally though you'd eat when you woke up or you would wake up, do some cardio, then eat your first meal. School time that won't be possible though, so Ill just eat alot in the morning and night time reach the gym. Won't lose as much weight but will still be getting awesome results. This diet can be modified to ones own time/abilities, you will lose weight no matter what, just the more factors you keep strict about it, the faster you will get results. My buddy tells me if I weigh my food Ill lose up to 500 extra calories a day just for doing that.
