Some Rules & Calculations

From the P90x Diet Manual.. where should I be in terms of setting up my diet & workout plan?

P90x Diet Schedule
-------------------
Phase 1 (Fat Shredder Plan week 1-4)
Phase 2 (Energy Booster Week 5-8)
Phase 3 (Endurance Maximizer Week 9-13)


P90x Hydration Schedule

------------------------
12 oz. water two hours prior to exercise
8-12 oz. water 15 to 30 min prior to exercise
4-8 oz. water every 15 min during exercise

P90x Results and Recovery Forumla
---------------------------------
Have it within 1 hour of your hardest workout.
Save the recovery drink; if you did light workout, wait til you've done a harder workout that day and use it.

Cook meat, poultry and seafood without oil using grilling

Calculations
---------------
Resting Metabolic Rate (RMR) - Number of calories I need to breathe, pump blood, grow hair, etc.

RMR = Body Weight x 10

My RMR = 185 x 10 = 1850

1850 calories required to be alive

Daily Activity Burn (DAB) - Calories required for daily movement apart from exercise.

RMR x 20% = DAB

1850 x 20% = 370

370 calories required to move around daily

Calories Needed to Exercise for P90x = 600 calories

Total Calories Needed
= RMR + DAB + 600
= 1850 + 370 + 600
-------------------
2820 calories/day

I fall into Nutrition Level 2 of the Diet Plan for P90x (2400 to 2999 calories)

Current Body Fat:
26.5%

Body Fat Target
For Men
Fit: 14-17%
Athlete: 10-13%
Elite Athlete: 4-9%

How Many Pounds of Fat Do I Have?
Total Weight = 185 lbs
Body Fat% = 26.5%

Pounds of fat = (Body Weight x Body Fat Percent)
185lbs x 26.5% = 48.1 lbs of fat

Pounds of lean body mass = Total Weight - Pounds of fat
= 185lbs - 48.1lbs = 136.9lbs of lean body mass

Formula to reach target goal weight:
Goal weight = (Weight of Lean Body Mass / (100 - desired fat percentage)) x 100

Fit range = 14-17%

136.9/(100-17) = 165 lbs @ 17% body fat (GOAL)
