Peanut M&M’s would be better. Eating small portion sizes and more often is the main thing. Skittles will likely cause digestive issues because of the lack of fiber. How your body responds to all that sugar is also a long term issue, but age is a factor there.

I started my journey from 350 lbs to 190 lbs on Peanut M&M’s, Adderall, and way too much of an internet cafe. I just ate a few when I felt light headed, but was super focused on CS/BF/CoD. I only did that for a month or so after having to move back in with family. Then I started riding bikes a lot, like 400+ mile weeks.
