How you wish you could say the same right? 
Being blessed with a high metabolism rate and 4 children, I have no problem loosing weight. People that have not meet me for years asked whether I take any weight loss products. I showed them my 4 children, they smile. They are my weight loss product. 
Gaining weight is also easy for me. Just eat a lot and do nothing. Sure gain weight again. Unfortunately I do not have the privilege to “do nothing”. Eat a lot no problem. Also do when I have the appetite.
Stumble it!
For me, hard to lose weight and easy to gain weight. Sigh!
