Is it the weight loss formula or is it a change in body?

I tried a weight loss formula that totally deleted all hunger to the point where I only needed about 600-800 calories a day but now I wonder if the loss of appetite has nothing to do with the formula and my body is just spontaneously losing its hunger. I had a dream that God would help me lose weight if I trusted Him and that God would fix every bad part of my life.
Is it the weight loss formula or is it a change in body?
