The Day Late update!

I had my official weigh-in Saturday.
Lack of activity has led to an increase of 5 pounds and some change.
So my current weight is 190.1 which is better than I had imagined.
Plus I have some new stats which will give me a better target weight based on
body composition rather my earlier pick a number method.

Here is the formula that I'm using to determine my Lean Body Mass or LBM.
Current Weight 190.1
X Body Fat 23.3% or .233
= 44.3 pounds of Fat
190.1 - 44.3 = 145.8 LBM

Now I want to determine my ideal weight based on a Target Body Fat (TBF) percentage of 12%.
So I take my LBM and divide it by (1 - TBF)
or 1 - .12 = .88

145.8/.88 = 165.7 pounds Target Body Weight or TBW

Of course this is just a snapshot meaning if I were to maintain my present amount of muscle while working out then 165.7 would be my ideal for 12% Body Fat.
Hopefully I will replace a good portion of fat with muscle now that I have returned to the gym.

Current Weight 190.1
Body Fat 23.3%
LBM 145.8
TBF 12%
TBW 165

I'm glad it all makes sense to you. Clearly a chess-player's approach to weight-loss :)

Nah this is just math.
But it helps in showing why lowering overall weight isn't as important as lowering the percentage of fat.

In theory I could maintain my current weight of 190 and decrease my fat to 12%, which would raise my Lean Body Mass to 167.2
