Hey there Pudding
That's a great start cutting down on excess treats & sweets, and congrats on your loss so far! 20 lbs is awesome!
I don't know of any specific "for men" tips, but I think eating & exercising common sense go a long way with everyone here. For example, if you aren't exercising, or haven't in a long time, you may want to start out slowly, like taking short walks or doing small lifting exercises. If you start out small you can then build up overtime to what is healthiest for you. I began exercising by taking walks during my two short breaks at work. Very small amount, but I've built up to more from there.
About eating, having you taken a good look at all the other foods you eat? Are you getting enough fruit & veg? Perhaps you need to know how may calories you're eating. There are free online sites that help track or even a pen & paper works wonders.
Keep us updated on how things are going ^^
Best of luck!!!
