how awesome that you lost that weight
HAS helped you, just depending on how you lost the weight
and how fast, it might take your body a while to adjust your metabolism...
But, to be completely safe, you really do want to have monthly check-ups with your doc to monitor your weight, blood pressure, fasting blood sugars, and urine protein, just to make sure that no other potential issues might be going on.
Again, congrats on the weight loss!
