Awwwhhh...don't beat yourself up too bad. We all go a little crazy sometimes. I think it has something to do with looking fabulous and summer time!
So..ok...you went nutz. I ate 1/2 dozen literal Krispy Kremes in a matter of seconds!
Talk about your eeeeeeeeeeeek!
But yunno wut...over the weekend I ran sprints for 3 miles in the sand on the beach! I even beat a 20 yr runner in a 100 yd race in the sand...woo hoo!
My point...UPS and DOWNS...that's life. You KNOW when you've been going nutz on food and slackin on exercise for too long. One day...hey...no problem, but all week...well...ehhhh...could start to get the scale creep. I know everyone makes it sound like you just wake up one day, hop on the scale and learn you've gained 100 lbs overnight, but really???
My advice...continue to weigh yourself regularly (at least weekly) so that you can keep a check on your weight. Observe the way your "old" clothes fit. If you feel you've "pigged out" one week, then cut back a bit the next week. Weight gain is a very gradual process so you'll have time to either 1)eat less or 2) exercise more.
Hope this helps.
