I know of a sure way of losing weight effectively. But the means is not always pleasant because you have to be sick. I have an internal bleeding a couple of months ago and I have to have blood transfusions. I lost 6 pounds of my weight because of that. Ordinarily, I have to take about 6 month maybe to achieve that kind of weight loss. But being sick for a week make my body week and I lost a lot of weight quickly.
But, I realize that it is not a great achievement. Because I am proud with my weight and I just want to reduce my weight about 2 or 3 pounds. Losing a lot of weight is not a good thing for me because I always have this strange headache. Maybe I still lack blood volume. Every time I have to go through PMS, my headache is getting worse. I just wish that I get to normal soon.
