Can you stop asking this question?

NO!!!!!! Ok, well maybe. Ok, there is not a single food on this planet that will make you fat. How? It's not about WHAT you eat, it's about HOW MUCH you eat. I could write you a twinkie diet and you could lose fat if you are eating less than you burn- not the most ideal situation and you definitely wouldn't be healthy doing it- but it can be done.
Protein powder, by itself, WILL NOT MAKE YOU FAT. Even if you aren't lifting, drinking a protein shake WILL NOT MAKE YOU FAT. THE ONLY WAY PROTEIN POWDER WOULD MAKE YOU FAT IS IF YOU ARE EATING MORE THAN YOU BURN. SIMPLE AS THAT.
You could literally get fat off broccoli if you are eating more calories than you burn. Silly, right?
Protein powder won't make you bulky. Protein powder won't make you fat. Protein powder is a GREAT WAY to supplement additional protein into your diet instead of eating a chicken breast or another can of tuna. But again, you will gain weight from ANYTHING if you are eating more calories than you burn.
So please, drink a protein shake for me
