Generally, you will have a lot more options when you are at a healthy weight. Ask yourself if you would be more attracted to a fit person or somebody morbidly obese. It is human nature or maybe just nature that we seek out the most fit folks to reproduce with.
For me, I'm a tall dude at 6' 3" so I carry my extra weight better than most. I've noticed in the past that my social world doesn't open up unless I'm below a certain weight. In 2003, I weighed 380 lbs. with my ideal weight being around 220. I went on low carbs for two years and got down to 298. As soon as my weight got below about 300 lbs., I ceased to be invisible to women in bars. It was like a light switch had been turned on. I wasn't a "10" but any stretch but at least some percentage of the opposite sex now deemed me viable. Pretty much everybody treated me better. I hadn't realized how people had been treating me until I dropped the weight. Of course, it didn't stay gone and now I'm back up to 360 or so and my social scene is a solo effort yet again.
You may have to shed far more weight to FEEL deserving of affection from very attractive people than you will to actually get the affection of very attractive people. When I got down to 'only' 80 lbs. overweight, the best looking girl I've ever seen was into me. It became crystal clear only later and at the time it wasn't even a possibility in my mind because of my self image issues (and I was 13 years older and thought she was out of my league). So, do your best to adjust your mental game to your new body image as quickly as possible. I sure wish I had.
