First of all...it happens. In the last two days i started my period and consumed somewhere between 3 and 4 boxes of pudding (fat/sugar free, but still)/
1. Let it go. It's done, you worked your butt off at the gym so it's not as bad as if you hadn't exercised at all.
Next, maybe you need to have a bigger breakfast that will keep you sated longer? Oatmeal? oatmeal with a banana?
Perhaps bars work for you and this is an anomoly but I find that bars taste too much like candy and get me craving snacky candy crappy type food.
If I start my day off with oatmeal and a banana it doesn't make me crave chocolate for example.
But don't beat yourself up about it. I seriously ate over a pound of pudding.
I choose to blame my period and I know it's not going to happen again...this month
