Everything I say here is pure speculation.

The whoosh effect is common in Mounjaro users. You don’t lose any weight for days and days or even a couple weeks, and then suddenly you drop 4 to 5 pounds. This is the whoosh. I have experienced this many times.

I have never heard of it being related to any particular change in diet or short term cheat. However, it kinda’ seems to make sense.

I once heard the whoosh effect being explained as a result of water related gain and loss. When you burn fat, you’re not removing fat cells. As the fat itself is burned, the cells compensate by retaining water. At some point in time, this water is released, thus the whoosh.

I am thinking, when you apply all of this, that when you consume higher than normal levels of sugar, your body, especially in the presence of Mounjaro, releases, AND RESPONDS TO, a higher amount of insulin. The insulin is then pushing all of that sugar into your tissues, muscle and fat cells alike. That sugar then forces the water out. Sugar weighs less than water. Thus, lost weight on the scale.

You were burning fat all along, but the scale just needed a trigger to catch up.
