Don't give up. Keep doing what is healthy and exercising. I hit mine right after Thanksgiving. So mad I could spit. But I tweeked my diet, added strength training and increase my walking and bike time. Began losing weight again. Have lost 3 lbs. in 2 weeks.
As to doing 1750 calories. Maybe you need to increase them. I did. With all the exercising, etc. I wasn't eating enough. I know, it doesn't make sense, but it's true. I didn't believe it,but do now.
Just wish I had made the adjustments sooner. But didn't gain anything, so that was good.
Keep up the good work.
