I was in your same shoes once. I was 28 and 290+ pounds. I'm now down to 240 one year later. What I can say for myself is for whatever reason, Alcohol and Nuts always seemed to deter my weight loss. I'd ditch both and replace with protein & veggies. I would also make sure you're lifting weights and sprinting once a week. It's amazing how easy the weight falls off when doing that just once. I'd also go for fattier meats as they are more satiating rather than chicken breast. Go for grass fed ground beef for burgers or something similar. When I eat low fat meats, I tend to be hungry all of the time and over indulge in calories and snacks.
