Weight Loss Goal

Been trying to start again my weight loss program. I have lost 20 kg. I weighed 105-110 kg last 2013. Today I weigh 85 kg. I've thought if only Im serious with my diet, then I've been losing more for 2 years, way up too long right? The yoyo thing is when you lose weight for let's say 2-3 months and then you gain again after losing a couple of pounds. And that is because you can't control yourself and due to lack of discipline. So my deal with myself and to somebody who read this, let's have a strict compliance with our diet and most especially with exercise. They used to call me calorie freak 'coz I used to count all the calories of my food intake but I don't mind them. I have goals to meet. I wish this is the start of my real strict weight loss regimen.
