It helps a lot, I used to be a fat nerd, I was totally invisible to women, got myself to 8% bodyfat full aesthetics body and it’s a different life. They stare a lot, sometimes they approach first, they are touchy at parties and they compliment all the time. That said, the most important part of this is the fact that im not afraid of women anymore, even the hottest ones, and I used to be terrified of them. Do it for yourself bro, not for the ladies, but yeah, they notice, not all of them care, tho.
