I was so surprised to read what you've achieved!! By reading your chart it seems you've already lost about 45 kg or 95 pounds.
Well, congratulations. You've done a great job. So, what do you have to grumble about? Of course it takes long to reach a perfect shape , but, having said that, are you sure you're still so overweight? Not to doub what you write, but I was just considering my partner. I've just tried to calculate his MBI and he's 29.3, which means overweight.
He's always done quite a lot of sport and he still plays basketball, despite his age (42) . So, I'd say he's a bit overweight, but it's not so evident. Plus, I like him as he is.
On the other hand there's me, with a BMI of 23.8/24, which is considered normal, but I 'm not at all happy with that. So, I wonder, is BMI a subjective matter or a matter of how perceive ourselves?
But if you want to loose more weight and be in control, why not try to water fast only one day a week, just to give a shake to your metabolism, instead of fasting for a longer period but with a higher risk of putting back on the weight once you break your fast?
