First, let me say I would be very frustrated in your place.

I can't really know what's going on based on a few sentences, but here are a few thoughts to consider--hope one or more provide possible insights:

• when weight loss isn't happening there IS a reason but it can be--as you've found--very hard to isolate what it is.

• you appear to be locked in an internal battle and, believe me, I've been there. Namely, part of you wants to work on your weight and part of you is "hungry." I used quotes because what you are perceiving as hunger may/may not be that.

After about a year of successes and bumps, I have narrowed my philosophy of eating to: don't eat until you are hungry (stomach/gut hunger, not brain) and eat enough high-volume, low-density foods that it's easy to reduce portion sizes on the richer ones (from the variety of whole foods.) Yep, that's it.

Your question appears to describe the experience of hunger driven by your brain chemistry (cravings) rather than your gut (stomach pangs, squeezed feeling.) You are feeling the cravings because your body currently prefers to burn the food you eat rather than stored fat--and you are eating enough food that it doesn't have to switch to burning fat.

So what can you do? If you already tried this, I apologize, but what helped me was to eat a large helping of fatty beef as my first food of the day. A large helping would be 4-8 oz; adding 1-2 bacon strips would be fine too but I had to avoid eggs as they actually stimulated my appetite. Others find eggs filling, so you follow what's true for you.

After my large breakfast of fatty beef I didn't eat again until my stomach/gut actively asked for food. Since my brain was screaming for carbs long before then I had to get away from food by driving, walking or going to the thrift/hardware/greenhouse and browsing.

In the afternoon or evening, if/when stomach/gut hunger became active, I had more fatty meat with non-starchy vegetables or low-carb fruit. Vegetables included leafy salad, asparagus--nothing richer than those--and fruit was grapefruit.

With that approach, I slowly and gradually shifted my metabolism toward fat-burning. Please note that if you eat enough fat and protein to live on, you will NEVER reach ketosis, so once your appetite is in better control you'll need to gradually reduce your portions to just a little less than you can live on and then you should release and burn stored fat.

I hope something I've said gives you an idea--good luck!

Hmm... I would personally go to an endocrinologist to check full thyroid (not just the 2-3 tests the normal doctors do). If you have thyroid issues that would explain why you can't lose not even a single pound. But you obviously need to stick to the diet for more than 2 weeks to make sure that indeed you don't lose. If you're binging on pizza it's because you're not eating the right foods. Eat more fat if you're hungry, more fruits if you crave sugar. But definitely stay within Paleo and don't cheat with gluten.

To be perfectly honest, maybe you have to really look a little deeper at what you're eating and how much of it you're eating. If you're eating chilli and you're still eating beans (and a good amount of them), then that probably won't help, but I'm not sure if you are or aren't. Only you know what you're actually eating.

Have you tried to count how many carbs you really are eating? Are you being honest in your assessments of how much you "mess up" etc?

Sometimes it's just about taking an honest look at what you are actually eating and fixing the problem there before you can do anything else. I know; I've been up and down the weight rollercoaster forever, and this seems to be the only thing that has worked for me.

If you have a smart phone, try using the app called "The Eatery" and snap EVERY SINGLE THING YOU EAT for a week and then come back for an analysis. You may be slipping up more than you think, which is why your body hasn't gone into ketosis.

Also, if you feel hungry, try eating more fat and protein, and much more vegetables, and whatever you do DO NOT BINGE! Just don't do it, and don't use "I'm hungry" as an excuse to eat pounds of pizza. Instead, try making healthier versions of these things at home (ie Cauliflower pizza).

Also, take a look at your workouts, and make sure that when you do have higher intensity days, that you actually work to that intensity.

If you're honest with your body, then you will see results.

"What you eat in private shows in public"

Are you truly living by all the PB principles? Its much more than just what you eat. You didnt mention your daily activity/exercise habits ie lots of long walks, a few strength training sessions per week and the occasional sprint workout. I think your on target with low carb however my guess is that your not adding enough fat into your diet. You dont have to measure or anything but consciously double your fat intake and see how you feel. If still getting cravings, triple the fat. This should drastically reduce your cravings to binge eat and very likely support a better hormonal profile. You sleeping 8-9 hours daily and getting plenty of sun? If no sun make sure your getting a good amount of sardines and liver in your diet for vitamin D. Finally, it sounds like you need to focus on stress management as well perhaps just 5 or 10 minutes a day of meditation. Good luck and let us know how your progress is coming along.

I have been following paleo principles for about a year now and though I have lost a few inches, I did not lose weight until recently. What worked for me was to track my food on myfitnesspal (or similar program). Until I did this, I was not realizing what non paleo food was slipping in, how many calories I was really eating or what my ratio of carbs/fat/protein really was. While I look at the calories and take that into consideration, I mostly use the tracker to see how many grams of carbs/protein/fat I get. Most programs are based off a typical high carb, low fat diet so you have to manually adjust the percentages to meet your goals.

Also, I have tried some principles of the Kruse Leptin rx.. Specifically the very high protein and fat, very low carb breakfast. I tended to snack on nuts, fruit (which caused me to way underestimate carbs) etc during the day but with 50+ grams of protein in bfast... I can have just a very small lunch or no lunch at all and make it to dinner without cravings.

Between the accountability, tracking, and large protein breakfast, I am finally seeing 2 lb a week weight loss after a year of paleo. I would definitely consider trying the tracking for a week and see if things are matching up! Good luck!

Lifelong fat girl who still struggles from time to time here. I totally understand your frustration. Can you post some more specifics? What a typical food/activity log might look like for you, what's the longest you've gone "strict", etc.?

You mention baby weight. If you have a young child around, I'm guessing you're not sleeping much. Sleep is a much bigger piece of the puzzle than most people realize. Cut yourself some slack and focus on putting quality foods in your body and caring for your little one.

Here are a couple of other thoughts off the top of my head:

Commit to strict Paleo/primal for a full 4-6 weeks. Just make up your mind and do it. Don't worry about ketosis or IF or anything else. Even the workouts aren't nearly as important as your nutrition and your sleep and stress levels. Seriously. Don't worry about anything other than putting high-quality meat, fat, and veggies in your body and getting good solid sleep every night (if possible).

Keep a journal. Log your food and sleep. It would be really helpful to keep track of sleep quality, workout quality, mood, cravings, etc. You'll see trends eventually, and that will tell you how you do best (high- or low-carb, 2 meals or 5, etc.).

Good luck, and keep us posted.

I am in this exact same situation, I eat paleo for about 3 days then I eat half a large pizza, because I see no results. I binge when I try to fast too. Everything you described is me to a 'T', you for sure are not alone. I'm looking forward to an answer to this too.

The thing in the OP's post I notice the most is that "Binge" shows up four times in the entire paragraph.

Regardless of all the chemistry involved in nutrition, you can't eliminate the first law of thermodynamics in your efforts to lose weight: calories in must either be transformed into heat, movement, or additional body tissue (fat or muscle or body repair). Excess calories will turn into fat. Try a calorie count, odds are you eat much more than you need.

If you are having a hard time stopping eating until you are "full" (not satiated, but overfilled, there is a difference), then I would not eat as much fat calories (the fat will add 9 calories per gram, versus 4 calories per gram of protein or carbohydrates). If you must binge, do it with less caloric foods like whole/raw fruits and vegetables. They will be much more filling, add nutritional value to your diet, and also add some water to your gut (plus feed the flora of your gut). Protein is still good, but most sources are dense and heavy, which does not add to the "filled" feeling you need to stop eating.

Do this, and you won't have to worry about the composition of your diet in terms of fat and protein and carbs. Fruits and vegetables are far lower in carbs than potatoes and grains, but will keep you filled and fight hunger. They are also far lower in calories than protein and fats, so by volume you can eat more while still having lower carb intake.

I'll guess that you have some other hormonal problem that is holding the weight on despite messing with calories and macronutrient ratios. I'd suggest you go over to the MDA monster leptin thread or Jack Kruse's forum and see if you can learn something there.

I would definitely consider your leptin levels and look up Dr. Kruse's info and think about getting your leptin levels tested. I did and it certainly validated the insanity I was experiencing.

Your story really resonates with me - as i have been consistently struggling with fat loss too. I have also been in the same mindset as you on and off for years.

I just recently started actively counting calories and i'm noticing a slow but gradual shift to fat loss.

I was extremely resistant to the idea of counting calories (been there, done that in a very unhealthy way) but noticed that this time is much easier since i'm eating plenty of protein and enough fat.

Don't be too hard on yourself - there are a ton of people where you are right now. Losing weight (and keeping it off) is one of the hardest things in the world to do.

I recommend thedailyplate.com. Type in all your info and weight loss goals - set it to a "light" activity level..then log any additional exercise and make sure to eat back those exercise calories you burned.

Of course ignore the macronutrient goals at the bottom and stick to primal eating principles (but i would recommend adding in more carbs through fruit and sweet potatoes, even rice).

Try this for a few weeks - see if anything happens. I bet something does :)

I will never forget the great work of Dr.samoda in my life. I was terribly ill and the doctors confirm that I can’t be healed completely for this I was frustrated and my increases as time pass on. When I meant Dr. samoda online I discuss my situation with him, and he said nothing is impossible. He ask me to send my photograph which I did and he bought some materials which he used for me and I was able to regain my normal health after a week. When I went to my doctor for check up he was surprise and said unbelievable that my health is normal and my body weight equally normal. My greatest thanks to Dr. samoda if you which to contact him, his Email samodaspellhome@gmail.com

you should consult with specialist

There's been some really good answers in this thread and nothing I can add to; I just want to know how you're getting on?
