A glass of wine is 70-100 calories, and most of that is from the alcohol. Keep in mind that alcohol impedes fat burning, so limit to no more than a glass/day and factor it into your daily intake. If you are adding sugar, just figure out how many calories are in the sugar you are adding and then divide that according to the size of glass you drink.
I've pretty much stopped drinking during the week (except on date night), and have dropped from 5 or 6 on Friday evening to 2.
But the goal is the goal!
Also, don't worry about
every single calorie. I shoot for an average of 1700/day, but if I get 1900 or 1500 it doesn't matter since I'm aiming at a weekly target, not a daily one.
Edit: At my calorie level, I can take in 11900 per week and have a 1400 calorie/week deficit. Add in exercise and I can trim that down below 3000 or more on the week, which is roughly 1 pound plus.
