Remember that bottom line is: calories in vs calories out. Don't get bogged down in all the other stuff that diet pills, websites, infomercials on fad exercise equipment, and other advertisers try to tell you.
It actually doesn't matter if you eat whole milk or skim milk. It's a good method for cutting calories, but it in and of itself is not going to make you lose weight. Whole milk has more calories than skim, but what matters ultimately is that at the end of the day you reduce the number of calories. If you drink skim milk but eat too many calories overall you will gain, just as if you drink whole milk but eat under the number of calories your body needs each day, you will lose.
I think the previous poster is suggesting not to eat carbohydrates after 4 PM? Please don't worry about the timing of when you eat food. This is a dietary myth that has been thoroughly debunked. Happy to share resources on that information if you need it.
What ACTUALLY makes you lose weight is eating fewer calories than your body uses every day. All this means sensible portions and getting some sort of activity in (going for walks, riding a bike) when you can.
Start with that- it'll likely yield results
