I'm 6' 1" or so now, after losing a little height over the last 10 or so years - I'll be 60 next year. I'd crept up to nearly 250 a couple of years ago so I went low-carb and knocked off over 40 of that. A little of that crept back on, but not too badly. That was all well and good until last January when I started brewing.This year I've put back on most of 20 lbs since my lowest point summer before last. I decided I have to really watch it a little better and I've started dropping a few lbs again.
If I'm relatively active and a little careful about when and what I eat and limit myself to one beer most evenings for a while, I'll drop a pound or two a week until I hit about 215. From there, I have to work at it or really not drink at all for a while to make much of a dent.
If I have a lot of beers aging out, I'll want to try 3 or 4 in a night, but if I'm minding myself a little, 1 or 2 will be more the norm. I almost never drink after dinner. I'll have a beer around 5:00 or so, depending on the day's schedule and usually open another while I'm cooking dinner. Sometimes I'll tell my wife to go ahead and eat while I sit and have one more beer, then eat after I relax a bit.
