My Nutribullet came with a useful recipe book and if you Google or look on Pinterest there are loads of great ideas out there.
I've been using the My Fitness Pal app alongside it and I've been surprised as how calorific some fruits are so tracking what I put in is helping me lose weight. I put the Nutribullet on my scales then zero them and zero again in between adding each ingredient so I can keep track of what I'm putting in it without faffing about.
I started using the Nutribullet for breakfast and now I'm doing lunch too, which is what they recommend, and I'm losing 1-2lbs a week.
