Calorie intake & Activity Patterns

[drvali]

Hi, quick question:

Objective
I want to lose fat/keep muscle.

Stats / Plan
I'm ~145lb, under 15%bf, male, working as a programmer (so I don't move much).
My BMR is ~1650 calories.
I walk ~12km per weekday (~800cal)
I hit the weights 2 or 3 times per week (~300cal)
I eat about 200g protein, 40g fat and 75 to 200g carbs (more on gym days or every other day, I measure everything).

Calorie Intake & Activity Patterns
9:00am eat +300cal (more carbs)
9:30am walk 6km to work (-400cal)
1:00pm eat +400cal
- If it's a gym day, gym goes in here.
4:30pm eat +300cal (more carbs)
5:30pm walk 6km home (-400cal)
7:00pm eat +200cal
10:00pm eat +300 to 700cal (more carbs)
------------------------------
Intake: 1500 to 1900 cal
Burned BMR: 1650cal
Burned Activity: 800cal to 1100cal
Balance: -850 to -950 calories / weekday (balanced on weekends, I walk less)

The questions is:
Is it stupid to keep a negative calorie balance the entire day until that last meal of the day? Will this mess up my metabolism? (Hormones, etc)

The reason I ask is because my belly skin-fold measurement did not go down from 170lb to 145lb, but i'm losing fat for sure (I can see it in the fat folds)

Any experts around that could explain?

IMO I think your worrying to much about the time you have the meals. I know that most people will say otherwise but i think aslong as you eat less calories than your body needs you will lose weight. You burn calories just breathing so dont worry about having to burn everything off that you have just eaten.I just lost 7kg in 5 weeks doing the IF diet intermittent fasting diet. look at leangains. com it worked for me
Good luck :)
