7 weeks post op, eating normal. Can I still losing weight? I initially lost 30 lbs but nothing past 2 weeks.

Hello, I am 7 weeks out - post gastric sleeve procedure. Initially I lost about 30 lbs; however, I have not been losing any weight since. I am now on normal type food -but eat very little. I also have joined a gym recently and partake in spin class and yoga x3 a week. My question is why has my weight loss lagged? I take my vitamins and protein with very little carb intake. Any helpful hints would be appreciated. Thanks
