Weight Loss

I have been going up and down on my weight, As of right now I weight 315 pounds this is my heaviest . I would  be happy  to get back to my weight I was when I 1st met my husband at that was 190, But my goal weight is 125-135.  My husband went from weighing 210 when we 1st got together to his heaviest 475 he lost 150 pound but he is at 400 now. so we are doing this together.
