10% body fat is where life begins for a man in 2018. 12% max.

13-16% body fat
8-10% body fat
Once you hit 10% body fat plus having muscle you stand a good chance of being able to get women from it. Above that you need a Chad face/height/race to be able to pull women by physical attraction.
I'm around 14-16% now, down from probably ~20% skinnyfat previously. Looks much better already but it's nothing near attractive yet. Those 13-16% examples above look decent because they have big frames and lots of muscle. When you're smaller, ~15% still looks crummy.
Being defined (lean) is overall more important than being big. You need to see abs. I can just barely trace my top two now in the right lighting. Need around 5 lb more fat to disappear before they will start to actually look good.
Male requirements to be attractive in 2018 are through the roof. Compete or get left behind. On the plus side almost everyone of both genders are now fat so if you can get abs and don't mind fucking slightly chubby chicks, you will stand out for it even more.
Biked an hour today (700 cals burned). Took a spray of nicotine to suppress my appetite. Now gonna eat ~1200 cals and then stop for the day. It's fucking hard to do but so far it's worth it.
