slipped up today for first time and now debating quitting.

I've screwed up entire weekends before and I'm still here

This is life. Are you planning on giving up foods like noodles, pastas, treats, etc, for the rest of your life? You need to incorporate such foods into your eating plan, or you'll never be able to sustain this for life. Have noodles for one meal, and for the next have a salad or something else lower in calories.

It's not the end of the world. Eat it, track it, and move on.

Don't turn a bad day into a bad week....

I screw up at least once a week and I have still lost over 50% of my body weight in 22 months.... put it down to experience and move on - maybe cut back later in the day and save some calories that way, or go for a walk or do some other form of exercise.

xXx

The only advice I have is to remove the word diet out of your vocabulary. If you want to achieve your goals it will have to be a lifestyle change. Until you change your perception on your healthy lifestyle and daily habits, you will remain the same. You had a bad meal, so what, tomorrow is another day.

Please don't quit! I like to remember that my calorie goals are set to a deficit; if I do happen to go over them once in a while it doesn't necessarily mean that I've over eaten. I consider it a day at maintenance and I move on. There is a wonderful thread here on the forums where users celebrate their fitness goals one day at a time. Take a deep breath, acknowledge that what's done is done, and immediately get back in control. Keep checking in here with us. We're rooting for you!

I also slipped up today, it's my husbands birthday although you would have thought it was mine! Don't quit tommorrow is another day

If you are seriously considering quitting over eating a cup of noodles maybe you aren't 100% ready mentally to continue with your "diet" Like another poster said a diet ends a lifestyle change does not.

You can still have the foods you like just fit them in, and to me slipping up is intentionally eating high calorie stuff, finding out after the fact is not a slip up. I mean gosh I had gotten a small shake once had it, (was delicious) the next day while looking up the calories to log it found that it was 900 calories!! For one small shake!! I almost died when I read that....did I quit? Nope cause I am still here chugging along. It happens, that's life pick yourself up by the bootstraps and carry on.

It says you just joined MFP in September. I would suggest you may need to adjust your calories if they are too low. Then give it a try before quitting. I think a lot who join and try eating low for a quick weight loss (1200 calories) instead of a more reasonable amount have a harder time. I personally have upped my calories when MFP adjusted them to low for me (1420) and am still losing.
Don't think of it as a diet. Instead think of it as trying to have a healthier lifestyle.
Another tip that may be helpful try pre-logging your meals until you become more comfortable with the changes. I often pre-log my meals so I can go back and tweak things and allow for an evening snack.

I feel where you are coming from... I am a 0% or 100% with nothing inbetween type of person myself, and it is just that type of thinking that made me give up, only to start over again a long time later after Ive gained even more weight.

Like everyone is encouraging you to do, I suggest not giving up and just keep going. Had I not kept giving up just because I had one 0% day, I would have been where I wanted to be a long time ago. A cup of noodles is not the thing that will do you in, giving up is!!

So I hope that you give yourself a break and keep moving forward. That is something Im working on myself here, not just with food but with different aspects of my life. It's finally dawning on me that if Im determined to do everything perfect, Im just setting myself up for failure. But if instead I accept I will slip up sometimes and thats totally ok, because there will always be an opportunity to do better, then I am allowing myself a chance to succeed.

I know I am about to echo all of the previous posters, but reading your post I just had to reply.

I agree with the other posters who said that you need to remove the word "diet" from your vocabulary. If I thought of this process as a diet, and have in the past, I would fail and so I did.

For me, losing weight is never going to be living off of salads/vegetables (I can count on my hand how many I like!) and never making a mistake. I just try to eat as healthy as I can 80% of my day, and the other 20% can be something I look forward to. For example, I am a huge chocoholic, and make sure to factor that into my calories daily. Same for wine! I factor in a glass or 2 (or maybe 3! haha) into my calories atleast twice a week. Eating out? Doing that tonight! But I made sure to guesstimate those calories into my goal for today and worked out a little harder on the spin bike yesterday in preparation. And after all of these possible "slip ups" guess what? I'm still losing weight! I do notice that if I eat out for dinner that my weight might temporarily increase for a day or so, but I know it will come right back off.

So in summary, a cup of noodles won't ruin anything for you! Please do not beat yourself up over it. You will not be perfect during this process and when you are able to accept that it will be so much easier for you and you will be successful. Life happens! Don't worry!!

Also, I find that prelogging my food for the day has really helped me keep within my limits. Perhaps consider trying that out?
