Physically I'm not seeing much change. Since my body isn't used to caffeine anymore (don't drink Coffee), when I do drink some, it has a serious impact. I can also tell when I eat like crap. My stomach used to be made of iron. Now i'm mindful of the potential backlash later if I eat like crap. On the very rare occasion that i do eat fast food, the feeling of grossness is almost immediate. it's not regret because I love the taste but my body just hates eating shit now.
Mentally it has it's up and downs. Some weeks I can coast on cruise control and never even get phased. Other times I struggle. I think my approach of not throwing myself 100% into it is the difference maker. I did this once before and it only lasted about 2 to 3 months. I'm 6 months in and feel that I'm still going at it strong. I love that I still get to enjoy some food but 90% of the time I'm on a fairly lean diet. My week day meals are typically white meat, brown rice/vegetable, and some low calorie/impact side. On the weekends I still eat fairly healthy, but I don't focus on it. I still typically eat decent even on the weekend just because my portion control is good and I'm mindful enough to not just gorge myself.
