So disappointed in myself!

Start small, don't go whole hog. I have no idea how much you were eating before, or what constitutes "falling off the wagon" for you, but let's say your previous diet was 2500 calories. Going to 1200 in one bang is a drastic change. Start smaller. Got to 2100 for a few days, then to 1800, then to 1500 and see how you feel. You can probably lose on 1500, depending on your sex, height and weight, you can probably lose on more than that. Make swaps, sodas for diet, juice for water, extra lean beef for "regular", etc.

Set a realistic goal (1 lb/wk loss) and go with that. Slow and steady with small habit changes will be the secret.

If you eat toooooo low....you are more likely to fall off the wagon.

Do the calculations right, be patient, you didn't gain the weight in a couple of weeks....so its not going to come off in a couple of weeks.

Two methods:
MFP calculations with using their exercise calculations...you eat at least 1/2 of those exercise calories back.
In MFP use GOALS

TDEE method (exercise is included in the total) you minus around 20-25% and that's what you eat EVERY day. you only track calorie totals in MFP (no exercise tracking).

use calculator or any other similar one: http://www.calculatorlab.com/HowDoIMeetMyWeightLossGoal/

Then in MFP
GOALS / CUSTOM GOALS and plug in the calories from above.

Figure out what kind of workout you like to do...maybe a mix of strength training and a little cardio for example.

Please dont beat yourself up about it, its a waste of time.
It just sounds like you lack focus and making the commitment to take it seriously.

If you approach it with the correct mindset, then you will know what the answers are each time you come to make that decision. Virtually all of us love food btw, but we wnat to lose weight so we move more steps forward than back by keeping a deficit by logging food accurately and moderating our concumption by smaller portions and sometimes saying no, but being relaxed not to ban any foods or treats.

I guess sounds like you havent got enough confidence, there is no guessing and you need to believe you are capable and can lose the weight if you wnat it badly enough as long as you reteain a cnsistent deficit and get into a few good habits. YOU CAN DO THIS.

I dont know your stats, but always find 1200 a bit low, so put your numbers through again and increase the calories by maybe going for a a bit less of a weight loss. i.e 1lb a week instead of 2. That will give you extra calories and may make it easier for you to sustain. The danger of going at too severe a deficit is you crash out and then binge. You wnat small victores at first and then that can encourage you for more and you will find your feet with increasing confidence.

The other side of the equation is move a bit more to burn more and maybe earn some eatback calories.

Stop shaming yourself for eating; eating is important and you cannot starve yourself healthy. If you want to change, you need to find a way of eating that's sustainable long-term. Up those calories, don't be afraid of food and stop trying to quantify food as good or bad. It's food.

Your profile says you want to lose 35 pounds. I'm going to assume that you're not obese and close to a healthy weight. You'd be better off with a smaller caloric deficit, anyway; you need that fuel. Your body will thank you.

I found that allowing things like sweets, booze and other supposedly "bad" things in my life kept me from binge eating. I just don't eat them all the time because they don't keep me full.

PS- I end up around 2k calories a day and I'm still getting smaller. I'm in a US 10/12 and started at a 24.

Don't be so hard on yourself. Don't set "HARD" limits on your food/calorie intake, and don't stress out if you're over one day - those days just try and stay under maintenance. For me, moderation has been key. Good luck.

I'll just leave these here for everyone to read:

First, you need to change your mindset. Losing weight is not an all or nothing endeavor. It's best to take small steps toward your goal, start with changing one or two things, and add a new goal every week, while you continue with the others. It can be as simple as drinking 10 glasses of water, or walking at least 20 minutes a days. Also, food, and even drinking, are not "bad" in of themselves. You can fit anything into a diet for weight loss, even the occasional drink or 2. I do it, and have been able to enjoy myself now having 1-2 beers, a couple days a week, and it doesn't ruin my diet.

Starting out trying to eat only 1200 cal/day is your biggest mistake. It's not necessary, and nearly impossible to sustain long term. I have had to learn this the hard way, as well. I tried losing 2lbs/wk and found I was instead losing nothing, or less than a pound, because I would feel hungry or deprived and end up bingeing, putting me back at maintenence level. Now, with my goal of losing 1lb/wk, I can eat 1800 cal/day, or over 2000 if I exercise, and I am greatly satiated with no hunger or cravings. I have room for dessert, and even drinks some nights!

Most importantly, take it one day at a time and do the best you can in the moment. Everyone falls off the wagon once in a while, you just have to be able to get right back on. And for goodness sake, don't hate yourself for it!
