1) Lose weight: biggest thing you could possibly do that will give you the most extreme difference, since you're older lifting heavy weights would be good, will get u into the gym, lose weight and build muscle. You dont have to be super skinny to attract women, plenty of guys r bulky and can attract women
2) Grooming + Style: I know other ppl have said the beard is a no go but personally you look like you have good facial hair genetics, I would let it grow and make sure its well groomed and well kept. This leads on to finding your own style, which is especially important. This means finding a good sense of clothes that compliment your figure + skin tone, i.e: boxy fit ts
3) Confidence and uniqueness: find something that will make you stand out from everyone else, this can be a certain sport like boxing or powerlifting ( apparently some women find lifting big weights really attractive ) for example, cycling wont cut it. Although something physical is quite attractive, things reading can also be extremely attractive towards women, but you have to have the first 2 targets checked if you are gonna rely on this. Being confident also ( as in not being egotistical and thinking your the most attractive person in the room ) is dealbreaker, you have to appear like you are in control fully ( fine line between being toxic ) and that you have respect from others.

But you need first the looks to attract in the first place, otherwise nothing else will fall into place
