If I take vitamin E capsule (200 IU; 1 per day for 1 month), will I gain weight!?

I am on a diet to loss weight. I also do exercises and gym. Is this vitamin supplement going to affect my body's metabolism system, like slowing it down? Or is it going to add fat in my bod as a side effect. I will take this supplement specially for hair. I know this vitamin is 'fat soluble vitamin.' :-s
