What do you think of people saying weight loss is 90% diet and 10% exercise, unless you do weight training which would change the percentage?

I believe that vitamin B burns belly fat cause just by taking vitamin B in its 8 forms and not exercising or changing my calories, my belly has shrunk to the point where my pants fall off and won't stick to my stomach anymore. I also have this theory that the choline in eggs burns arm fat so I purchased some choline supplements from amazon this week and it should arrive soon. My theory is based on the fact that every person I know who has skinny arms eats eggs on a regular basis.
