Do b12 injections cause weight gain?

I took these shots last year because my fatigue was hitting my office work badly. No weight gain happened, but honestly, you have to keep moving. If you just take shots and sit at a desk all day, weight might go up due to lack of activity, not the injection.

I agree with others here. In my experience, B12 didn't cause actual fat gain, but it definitely increased my appetite a lot in the first few weeks.

Actually, medically speaking, B12 does not contain any calories, so it cannot directly cause weight gain. My doctor explained that when your body finally gets enough B12, your metabolism gets back to normal, which might increase your appetite initially. If you watch your portion sizes, you won't see any extra weight on the scale.

Mere saath toh ulta hua, I thought I was getting fat but it was just some mild bloating. Within 2 weeks of finishing the course, my weight was completely back to normal. Just chill and complete your dose, dont overthink this.

Yaar, I can barely sleep 5 hours a night and I took these injections hoping for some magic energy. I didn't gain weight, but I did eat a whole tub of ice cream because the shots made me extra hungry. Blaming my late-night cravings for the weight, not the B12!

My teenage daughter had severe B12 deficiency and doctor prescribed these shots. She actually did not gain any weight at all, but her energy levels improved so much that she became more active. Just keep an eye on their daily diet and don't worry too much.
