There was a passage in the weight loss bible (Dr. Phil's The Ultimate Weight Loss Solutions) that told a little story about setting yourself up for success and that may include making some really tough decisions in regards to the people you're with and the surroundings you're in on a regular basis. One story he told was of a man who took a different route to work in order to avoid driving past McDonalds and tempting himself. Another story was about a kid who quit working at a video store where candy and sweets tempted him and found a new job at a gym. Reading that passage and really taking it to heart meant I needed to make some changes in my life as well if I really do want to succeed at weight loss.
It's pretty amazing how simply cutting out a few visual triggers can make such a big difference in your mental health surrounding foods but, at least for me, it's worked wonders.
I hope you're having healthy, successful weeks!
