Green leafy veges are brilliant! Also lots of green teas. I have found from personal experience and reading that these two items would have the greatest impact on my weight. And even more importantly, on the way I feel.
The easy way is to just increase the quantity of these in your diet. For instance, double the amount of greens you normally use in a stir-fry or salad or have two serves of greens with your main meal instead of one. I found this, bit by bit, eased up the cravings for carbohydrates and sugary foods. Very easy. You just need to be consistent. Hope you enjoy this tip.
