Going on a diet

I've been doing research the past few days on the most effective, yet healthy way to trim some fat and lose a few pounds. I'm tired and about to sleep but it will consist of:

-4-5 meals but smaller portions with less emphasis on lunch
-increased consumption of whole grain and non-refined foods
-1 day a week of red meat, 3 days of fish
-jogging at least 3 days a week for 30 mins
-drinking 1 nalgene water bottle a day
-eating oatmeal in the morning

I'm still researching but that's my small list for now, easily doable. If you have any additional tips or suggestions, it would be appreciated!
