I'm bored so I will spoon-feed you.
>What do I eat?
That's sort of an arbitrary question. If you keep things within your macros, you should still lose weight. But there are things that are better for you of course. Wheat bread is better than white and all that good stuff. Keep it within your calories and you should be fine.
>How much?
Again, track your calories. If you have a smart phone, there are a few apps that will help.
>What exercises do I do?
Depends on what is available. Are you going to a gym? You really can't go wrong with Strong Lifts with accessory lifts.
>How many reps?
Depends on your program. Can't go wrong with 5x5(5 sets of 5 reps). Get some cardio in as well.
>How often do I work out?
3-5 times a week is a good number.
As for a spotter, you don't need one if you're not a retard. If you know you might not get the next rep, dont. Simple as that. Save it for another day.
