@jsheed_sa , why worry about looking for ways to stuff in extra calories when you want to lose 7kg?
Maybe for now, eat the diet you pasted above, then see what starts to happen to your weight. In fact, if you want to lose 7kg in 12 weeks you are going to have to lose 583g per week. I say aim to lose more than that at the start, as the weight loss will actually slow down after a few weeks anyways.
If you get to your goal weight ahead of time, then there are plenty of ways to add in calories.
edit: Thor's advice for the extra calories sounds good to me![]()
Also agree with this.
