Just keep fighting the junk food cravings. Go for a walk, come to 3FC let us know about your day, get a diet buddy you can email with, talk to a trusted someone that gets excited about your success You said you were two weeks into this and in my opinion it take about 4 weeks to really get a good control over the cravings for junk food and do not beat your self up over a cookie. You had one cookie. To me that is great moderation if you only had one cookie. I trusted you ate it slow and enjoyed it , you didn't eat it like cookie monster
My only best advice for hunger and we all go through it time to time having hunger spells. If everything else fails and you must stick something in your mouth, try for a small salad or a favorite fruit. Time to time I'll hit those moments where I get a hunger spell and I done everything I could do to solve it, took a walk, got into a project, drink a glass of water, instead of grabbing for some kind of junk food, I made up a small salad or just grab an apple and the hunger spell went away but at least I ate something for the good.
It just comes down to making a good choice.
I had found out for myself that certain apples tend to kick out my sweet tooth cravings and we can give all the thanks to Lena for starting the whole
apple subject in the nutrition section. ( which was a good habit I learn from here)
