How do you cope with the hard days?

Make it fit into your daily intake somehow.

I switched over to having fruit with some cinnamon sprinkled on when I wanted sugary things (strawberries are my favorite). Already my tastes have changed and I rarely crave sugar. I actually find some foods too sweet now, like some banana bread a coworker made that I had troube finishing.

Maybe treat yourself to something small but special that isn't food, like flowers or a lipstick.

Also, try telling yourself that if you still want whatever you are craving by the weekend, you'll have some. This helps tell the difference between something you want just momentarily and something you really truly want and will feel satisfied after.

Realization of : Eating food does not solve my problems. It's same as smoking. Smokers usually chain smoke when they're stressed, or have a hard time. A non-smoker doesn't even think about it. Its not a necessity, nor fixes anything.

I think we've all been there though, its in our nature, we try to solve a problem by excess. Eating food in this case. Although there is one thing, when you're really hungry, make yourself a huge vegetable stir-fry, a nice big salad, some fruits, healthy snacks. It's much easier to binge on unhealthy foods when you're really hungry.
You just need to train yourself to eat at your caloric goal for the day. This is what worked for me though, I am sure people might have different experiences.

Sometimes you have to grin and bear it. At 12 days in it's pretty normal. At 100 days in it will still be pretty normal. Most people who don't have weight issues are good at eating things in moderation. With time you'll need to learn to balance moderation with cravings, and also learn when it's important to tell yourself, "No."

Sometimes you can't have the piece of cake, sometimes it sucks, but it's okay.

I try to allow myself one good thing that I love. For me if I don't. I won't succeed because I'll literally feel like I'm depriving myself and will be unmotivated. I think the key is to make sure u are controlling your portions and not over endulging.

I use substitutes for everything I can. look on pinterest, lots of ideas. Also I eat very small healthy things between meals so that I am not starving and it helps me not crave stuff so bad.

What helps me is to plan tomorrow's meals and put them in the next day's plan the night before. I also allow for my one piece of dark chocolate covered ginger before bed. It is on my food plan as well. I just work around those things and stay within my goals. If I have the plan written out, it helps when I get hungry or frustrated because I can see what I will have to eat at my next snack or meal. If you fall off the wagon, get up, brush yourself off, and start again.

You have to get beyond the all or nothing mentality. Nobody is ever 100% bang on all of the time...hell, even my trainer who is a retired professional athlete and extraordinarily fit has his "things"...it's not realistic to think you're going to be 100% all of the time. Life happens...sometimes it gets in the way and you miss workouts...sometimes best laid plans fall to the wayside, etc.

Beyond that, I just allow myself certain indulgences...they're pretty irrelevant to the whole of what I'm doing...for example, pretty much every Friday evening is movie and pizza night. I pick up the kids from school and we pick up pizza on the way home from our favorite little local pizzeria and we go home and watch a movie. Is it the most wholesome, nutritious thing in the world? No...but it's a fun little tradition and makes us all very happy. Sometimes I go overboard, and sometimes I don't...meh...it's pretty irrelevant to the whole.
