The last two weeks I've been back on low-calorie, lower-carb (LC2). The goal
was to keep at about 1500 calories while avoiding high-glycemic carbs that
cause hunger spikes.

I lost 3 kg = 6.6 lb during these 2 weeks.

Before this period I had a period of low-cal, followed by a period of
low-carb. I stopped losing weight under just low-carb, which is why I
switched back to low-cal again.

Anyway, the exact figures for the last two weeks are:

Average daily calories: 1422 (I was aiming for 1500)
Average daily carbs: 57
Average weight (assuming linear weight loss): 242 lb

Since I lost 6.6 lb, that was a total caloric deficit of 23,100 calories
over 15 days, or a daily average deficit of 1540 calories.

That means my average daily "maintenance" calories are 2962 calories.
Anything less than this amount means I should lose weight.

This comes to 2962 cal / 242 lb = 12.24 cal/lb. That is in the range of
normal metabolism.

This indicates to me that I could probably up my daily calories by a few
hundred calories and still maintain a 2 lb/week weight loss for the time
being.

I think the number of calories I eat should depend on my goal weight
somewhat. After all, when I reach goal I will have to maintain that number
of calories for the rest of my life, so I might as well get used to that
now, right?

I'm 174 cm tall. Assuming a high range BMI goal of 25, that means my goal
should be about 75 kg. That would mean a "lifetime daily average calories"
of

   75 x 2.2 x 12.24 = 2020 calories/day. About 2000 calories per day.

If I ate that much now it should mean a weekly calorie deficit of about 6734
calories, or about a 1.9 lb loss per week - almost 2 lb/week.

Assuming 10% error for safety (after all, it's a human body we're talking
about, not machine parts) I might try to up my 1500 calories/day to 1800 for
a while and see what happens.

Gee, I wish I weren't leaving on that overseas trip for month on Wednesday.
That is sure going to confuse the issue!
