I'm afraid the only answer is in your title, all you can do is keep chugging along.
When you've got 159lbs to lose, no, people aren't going to notice 24 of them; but your body is, and is thanking you for it.
You may well need to lose another 24 before people suddenly notice it - and then, typically, they'll seem to notice every pound after that.
Well done on planning for your Dinners; but if you starved yourself, does that mean you were ravenous by the time you got to the yummy food, and maybe the portions were bigger than you thought?
Plus, if the yummy food was turkey, then no problem; if the yummy food was (insert what all the other stuff is, I don't know but it always sounds high calorie and delicious) then a very little of it contains a very lot of calories.
Plus, if the y.f. was cookie-y, cakey, pastry-y, then there may well be a water retention factor, which is a pain but not permanent.
You need to have overeaten by 3,500 calories to have regained a pound of fat. If you did that, tie a knot and go on, you can't undo it. If you didn't, then it's a temporary glitch which will sort itself.
I really sympathize, I've felt that 'when will it ever/I try so hard, why doesn't it?' very often this year. From my experience, all I can say is to keep on chugging (in my case, plodding) and the snowball effect will happen, and the pounds will gradually accumulate.
Congratulations on the 24! Now, head down and chug on for the next 24.
