It appears though, the diet which seems to work best for most people is the Mediterranean diet consisting of lots of vegetables, unsaturated oils like olive oil fresh and fat fish (lots of omega-3), not too much meat (especially red one) and legumes (like lentils, peas or beans).
Also, unless you do lots of sports I'd recommend to reduce the amount of carbohydrates (carbs) you eat each day as they are mainly responsible for high insulin levels which prevent your organism from burning fat and furthermore damage your blood vessels. Some people favoring a life style with many carbs (A lot of bread, rice, noodles, pizza... etc.) react with insulin resistance at one point in their life time which can results in diabetes.
So, if you sit all day in the office and you don't feel like going for a long walk or getting out for a 30-60 minutes jog after work, dumb the pizza and noodles.
And needless to say, stop the sugared drinks and sweets because they're obviously worst of all!
Drink more water, it also helps to reduce hunger. Good luck
