My weakness is peanut M&M's, purchased in bulk at WinCo. Early on in my unemployment, I found myself gobbling them by the handful(s) well before noon and restocking my supply frequently. No longer. I still break down every now and then and buy a big ol' bootylicious bag on the weekend (what debauchery!), but I have definitely cut back.
I may be exercising more now that I don't have a job, but I'm battling stress fat (maybe — I feel less stressed than I was when I was working, so maybe this isn't an issue) and impulsive tendencies. Which means, when faced with the choice between an afternoon apple or ice cream sandwich, I'm not exactly keeping the doctor away.
