Try Intermittent Fasting. I.e. eat only during 8/6/4-hour window every day (I personally prefer 6). I find it much easier to live with the fact that at certain times I am not allowed to eat at all, than trying to control what I eat at all times. It also forced me to be more careful about choosing the right food during the eating window; I now want to get as much nutritional value as I can from my food, since the total amount of food I manage to eat in 6 hours is not that large. The first week might be a challenge in terms of managing your hunger, but it gets easier after that. I now see hunger not as a signal that my body is starving, but a signal that my body gets used to being fed at certain times of the day. I now feel hungry only about an hour before my eating window. I find skipping breakfast and any meals after 6 PM the easiest; but of course this might be different for you. It's just with this schedule your colleagues won't even notice that you are fasting unless you tell them.
