Consistency

So I feel like I've been inconsistent with my food habits in the past couple days. Snacking more often and feeling less focused in general on my eating. I feel this week may not be that good. I'm still working out, I just think I'm eating more than I should and I'm eating more processed foods than I was earlier in our challenge. I think part of that is because I'm almost to my goal, I feel like I can slack a little.
Any tips for remotivation?

Last night I ran 3 miles (intervals - kicked it up to 7.5 for 1 min twice). This am, the trainer for class had us spin for 20-25 minutes and incorporated some chest presses, shoulder presses, bicep curls while we were on the bikes. Tough workout. And then we did some additional shoulders and back weight training. Breakfast was 1 cup of kashi cinnamon harvest cereal and a smooshed fruit flat. Lunch was tuna sashimi (so good) and cream of broccoli soup. I snacked on a raw red pepper as well.
Have a great day everyone!
