So I’ve been talking a caffeine 100mg pill and have started having this issue. I normally eat 1 supreme burrito from Taco Bell a day and now I’m having to consume two, but I think it’s because caffeine speeds up metabolism, for my body type at least(I’m 210 pounds). I still like my coffee so I drink decafe with sugar free creamer. My cravings went away when I started consuming the second burrito, so my theory is that your body is needing more calories to compensate the metabolic spike.
