This guy is putting you on the right track. The way we tend to look at biology is warped as hell. It's rather simple to control weight.
Cut dairy and processed sugars, as stated
Remain hydrated throughout the day.
Limit meat intake (I'd say cut it out altogether if you're up for it. mean essentially turns straight into fat because it all cannot be processed in our bodies.)
NEVER eat an hour before you go to sleep unless it's something slight such as a banana or apple...
When you wake up in the morning, before eating a damn thing, have a tall glass of water or 2. Add a tablespoon of apple cider vinegar. Wait 20-30 minutes before having breakfast.
One of the most important things is to AVOID SHALLOW BREATHING. A lot of people are breathing into their chest rather than breathing into their stomachs as we see infants do. This hinders ALL bodily processes.
