I have "planned binges" all the time except I call them refeeds. They don't "shake up your body" but overeating does help reset some internal hormones specifically it can raise leptin which is an important hormone to consider when dieting.
A much better refeed is one that is higher calorie but much lower in fat. My refeeds usually span 2 meals and 5-6 hours in which I'll consume around 3,000 calories with a goal of keeping fat grams under 50. So I'm shoveling my face with bagels, pasta, sugary cereals, etc. At your size you would consume less. The idea behind high carb and low fat is twofold. Excess carbs are not converted to fat and fat is directly absorbed so you minimize and fat gain. Second, research has shown that excess carbs specifically do the best job of increasing leptin.
Initially I did this once a month. Now I do it once a week. Pretty soon I'll be doing it twice a week as I make my way down to single digit body fat levels. I have never stalled using regular refeeds.
Pretty good article here.
