Easy.
Watch the fat.
Watch the carbs/sugars.
Watch the sodium.
Do 20 mins on the treadmill at a reasonably quick walking pace 5 days a week after training.
Basically, watch the food.
First of all, there's a question that's pops up, you're gonna marry a girl with these kind of stats, but before getting married, you wanna drop a shitload of weight? I don't want to recommend you that, cause you gonna hurt yourself majorly in different kind of aspects.
You're gonna feel shitty and shaggy most of the days. That disappears after a couple of weeks. Keep that in mind, cause you gonna get triggered very fast.
Beside that, what does your wife look like. Maybe a rude question, but if you gonna drop like 20 maybe even 30 pounds before marriage, does she still wants you? Isn't she the kind of woman that love lovehandles. Or maybe she'll become jealous, cause if you'll succeed, you will get a lot of attention.
About training,
simple workout, make a split, one day upperbody, one day lowerbody abs, train four time a weeks. It's a workout tendend for beginners, but it will do the job.
After training, do a light cardiosession, like cycling or crosstrainer. Just make sure your hartbeat stays low.
On the days off, go jogging or swimming, max twice a week.
About food, you have to become a rabbit,
eat a lot of salads, just make your own with lettuce, cumcumber, cucumber, gherkin, tomato, and other vegetables(even fruits) that you like.
Ad a protein source like tuna or other fish, chicken or other poultry. Watch out with (tropical) fruits. I would stick to apples and pears.
Carbohydrates is a no-go, only exception is in the morning after waking up, and around training. And even in then, in small proportions, and right carbohydrates.
