I lost 12 lbs over 4.5 months, but now the scale isn't budging. I eat only twice a day - a small breakfast and small lunch at 3 PM. I walk 3.7 miles. What can I do to reset? I feel like I can't cut down more on food and don't have the time to do more exercise. I want to lose another 10 lbs which would bring me close to my ideal body weight for height. I am in my mid-40s and want to lose weight for health reasons. Any pointers appreciated.
