A lot of good questions and suggestions. My son drinks home brewed tea in the morning with a splash of cream; I drink it too but without cream, just because I like it that way. Both of us drink carbonated water (the slightly flavored type, like lime, not the artificially sweetened types) but he squeezes half a lime or lemon into it. I regard those as low carb but maybe it adds up.
I don’t consider myself an alcoholic, but alcohol is a thing for me.
And much of my initial weight gain years ago was from drinking high carb beer. To lose my weight I switched to vodka soda. A couple years ago I switched to drinking Miller Lite and found that I tolerate it well. I’ve lost a little more weight since then.
For much of the last 5 months he’s been doing keto, my son drank virtually no alcohol. Except at the pub he’d have 2 glasses of the lite beer, this is only on Wednesday when the wings are on special.
Besides the suggestions people have posted here, I’ll see if he’ll stop putting citrus in his water. But as I originally posted, the ketone strips showed he is very much in ketosis which I thought should mean his body is burning fat rather than carbs for energy.
