Must get on track and stay motivated...

For motivation: Have a goal, something personal to you that really gets you passionate. For me, I thought about all the things I can't /won't due because of being out of shape. My goal is to be able to climb Kilimanjaro in 2017, something I certainly wouldn't accomplish if I remain as obese as I am. For others, it's knowing they are more likely to be around to see their children and grandchildren grow up. Whatever it is, find something that has meaning to you, something deeper than wanting to look better.

For weekends: I always pre-plan and pre-log my food, particularly on weekends. I don't trust my hungry self to make great food choices, so I let my sated self do that in advance. I also don't eliminate foods I enjoy - even if I want something as nutritionally poor as a donut, I am fine with that, as long as I plan for it and log it. I'll eat pizza, chips, etc., as long as I eat them in portions that fit in my daily plan. That really keeps cravings lower than they would be, and it provides practice for a lifetime of maintenance - I'm certainly not going to live a life without pizza.

A couple of thoughts:

A) I do better on weekdays, too, so I "save up" some extra calories during the week and then "spend" them on the weekends.

in addition to logging, try taking pictures of everything you eat on the weekends. I found that adding the commitment of taking a picture of everything I eat or drink on the weekends adds a quick "stop and think" moment before I eat or drink something I'll regret later. I sometimes still make the "regretable" choice, but knowing I have to take that picture has also stopped me on many occasions!

If you're looking for motivation, you need to focus on finding your own motivation, not rely on others to give it to you. Take a good, honest look at WHY you're losing weight, not what others say or what you think it should be, and make that your motivation. It doesn't have to be 'to get healthy' either. That wasn't mine. For me, I knew I needed to lose weight and tried and failed a few times, but it was getting our wedding pictures back and realizing I LOOKED fat in them that I really found my reason for losing weight. I simply wanted to be able to look in the mirror or at a picture and look like myself. Getting healthier was a side effect to me, to be honest.

As for logging, make sure you're using a scale to weigh and log everything. Yes, it's a pain in the Justin Timberlake to do so, but you need to be as accurate as possible, espically when starting out. After a while, you'll train your eyes and brain to see what a proper potion of foods you eat a lot are and it becomes easier. What I did was weigh and log for a week to get a baseline of where I was at. Then, I started by changing one thing, gave myself a week to get used to it, then changed something else. Yes, it's slower, but I'm now at the point where I'm much more confident that I can keep my weight off because I know what proper portions look like. And if I want a cookie, I eat the cookie and can make it work in my daily goal.

And you will have off days. Days where you accidentally go over, unexpected dinners or celebrations, holidays, and days you just feel like crap and don't care. When those overages happen, simply log them and start fresh next meal/day. Everyone goes over sometimes; it doesn't make you a failure or sabotage your progress. Just makes you human.

motivation is and always will be a fleeting emotion. take the emotion out of it...in the long run, motivation is just barely a notch above worthless. ultimately, what you really need is discipline...discipline leads to consistency and consistency is what ultimately wins the day.

look at it like going to school as an example...you decide you want to get your degree so you register for university...you have a long haul in front of you...you're not always going to be motivated to get up and go to class or to study or whatever...but if you want your degree, you're going to be disciplined enough to do these things even when you're not particularly motivated to do them. eventually, you complete this class and that class and this semester goes by and that semester goes by...and if you're disciplined and consistent, you will earn that degree even though maybe you didn't ace every test or every class.

you don't have to be perfect...you just have to be disciplined and consistent.
