HELP! How do I stop cheat eating!

why I cant stop eating junk that ive learned is terrible for me.

Why is it so terrible?

My advice (and I appreciate while it works for me and others it may not work for everyone) is to not demonise food. You can eat everything, you just have to eat better portions. So me today - I've had 2 triangles of tolberone, 1 small bag of harbio starmix, and tonight I'll be having a small chunk of cheesecake (well according to my FB it is USA national cheesecake day - so what if I'm not American). I'm not worried about it, it all fits within my calories, and tomorrow I'll do the same if it fits.

Who buys the food? Start there. Is that you? Good. First stop looking at food as good/bad. Its just food. If it fits in your calorie budget for the day at a *reasonable* serving size, by all means enjoy. If not, put it away for another day. If there's something you like that you know you have a hard time eating in moderation(that is only two oreos which is a serving size instead of say, 6 or more) then maybe either buy ONLY single serving packs (if available) for those foods, or until you have established more self control don't buy it at all.

I lost a ton of weight 2 years ago, and since then I've kind of been on the process you are. I eat clean a few weeks, then I basically proceed to still eat all my clean foods, but also ice cream, timbits, half a pizza, etc.

For me, I find it happens when I'm being overly restrictive. Look at your diet and the type/amount of calories you're taking in. You can still have things that are traditionally bad for you; I still love ice cream even though it's loaded with calories, so I have small servings periodically. I also tend to make "treats" that I know will taste good and give me that satisfaction of eating something bad for me, without as much of that fat/sugar (something like these zucchini muffins: http://www.myrecipes.com/recipe/kathies-zucchini-muffins-10000001898573/)

The point is, you'll never be able to eat perfectly every day without being 100% dedicated to your weight loss, and let's be realistic, we've all got a lot going on in our lives and can't dedicate all our time and energy to this (as much as we'd sometimes like to).

Don't be so hard on yourself, try not to be too restrictive, and make room for the foods you love, even if they aren't traditionally good for you.

Like a few other people have said on here, I believe you CAN eat what you want, as long as it fits in your calorie goals. There is a reason fad diets don't work, and why yo-yo dieting is so common. People try to eliminate food groups, saying they are on a "diet" and will only eat clean food, with absolutely no junk. This typically does not work. If I had to eliminate foods from my life like pizza, chocolate, or wine, I most certainly would end up bingeing on those foods within a few weeks if not sooner! On top of the binge factor, once your "diet" is over and you begin to incorporate those eliminated foods again, you will probably gain some weight back.

My theory is to follow an 80/20 rule. I eat clean about 80% of the time, and eat what I want 20% of the time. As long as my calories stay within my daily goal, I am not too concerned. Think of this as more of a lifestyle change, not a diet. Don't do anything in weight loss mode that you will not be able to keep up for life. And unless you plan on never eating junk food again for the rest of your life, you should focus on learning how to moderate those foods. Like someone above me said, if there is a certain food you have little self control with, either don't buy that food or try to buy individual serving packages. Hopefully all of this helps you. Good luck!

There are very few foods that are terrible for you. Like others, I suspect the root issue here is demonizing and totally abstaining from foods you enjoy. You can include just about anything in a diet that allows you to lose weight and be healthier. You just have to be selective about the frequency and quantity. In my diet this week? Strawberry cheesecake, rootbeer, hamburgers, restaurant burritos, goldfish, a latte, and whiskey.

Im only 5 ft tall so what sounds like a little to some looks like a lot on me.

I had an horchata yesterday. I bought a small, then divided it between three cups for me and my kids. Even if a "small" of what you want is too big, you can subdivide that to arrive at your right portion size.
