And as a side note, this is one of the big deals about ingesting high fructose corn syrup (HFCS) - it bypasses the leptin receptors so that there's no signal to stop - people just keep drinking HFCS beverages & other foods.

Didn't actually know that one (though know that HFCS is far from healthy). Thanks Shanny.

Have actually just posted a link I was just reading on fructose and leptin resistance.

From article:

"We all know that the commonest lab finding in people following a low-carb diet is a dramatic reduction in triglyceride levels. This reduction in triglycerides allows the leptin that is already circulating in relatively large amounts to get through to the brain where it can reduce hunger. I believe that this reduction in triglycerides (which happens fairly quickly) is the primary reason that people substantially decrease their hunger on low-carb diets. And remember from the graphic above that leptin – once it gets to the brain – actually increases thermogenesis as well, which means that the metabolic rate increases."

I found this to be especially true for me. Upon diagnosis over a year ago, my triglycerides were approaching 200. My last test in May put me somewhere in the 80s.

All my life, I was unable to lose weight at anything much above 1200 calories, which I had done on and off for many years. This was also true when I began LCHF. Once my triglycerides went down (and I did not know the correlation), which took about 4 months to reduce by more than half, and better and better every time, something strange happened. I found myself to be hungry all the time. Starving. I thought my "Leptin meter" was broken because everyone else declared emphatically that their hunger "just went away". I was frustrated and discouraged by this because I also thought I hit a plateau after 6-months.

I couldn't explain it adequately, scientifically, but I did realize that I Needed more calories, not less. I went up to 2000 and beyond, being sure to stay at 30 grams of carbs or less with fat above 83%... the more calories, the more fat, keeping protein the same (back then, protein was about 66 grams) and maintained my weight loss.

Now, I seem to be going through this AGAIN! I lose weight at over 2100 and up to 2600 calories and maintain my weight (or gain) with anything UNDER 2100 calories. All with the same macros. WHAT is going on with me?? I'm so perplexed by this that I just keep eating the same foods day in and day out for lack of understanding as to where to go, how to proceed, what my body is doing, why,.. help!

Note: I am a sedentary creature, of late. I would need to eat much more to exercise, but I'm scared as to how much more. Perhaps this is the reason I struggle with energy? My vitamin and mineral labs are great. I went through similar distress when I went up to over 2000 calories.

I really need someone to bounce these things off of, even if there are no answers, thanks for listening.

Hmmm that is a mystery Bree! All I could guess is that perhaps when you went on LCHF it has raised your metabolism significantly. Maybe your previous way of eating, with only a bit over 1200 calories was too low and so you were effectively in starvation mode and so your body tried to hold on to the weight more? Now that your body is being fueled properly, maybe your cells can take up the energy more efficiently? Anyway, just my personal guess!

Maybe before your bsls were sitting higher, and so it may have blunted your hunger signals?
I hope you can figure it out.

Must admit, I have read this is normal for the transition period, but I am SO hungry some days. It seems I can eat a fair bit of fat, and then 2 hours later my body is irritable and asking me to feed it more! I especially crave cheese for some reason (I've been eating a lot of that lately).

Honestly, I pretty much just eat all morning and early afternoon long. It's quite funny and seems to have become my primary occupation. Ha! I guess it would be nice to figure out why this has happened. I may never know, which is frustrating as I must make adjustments with little to no empirical data. For now, I shall try to increase my calories further and listen to my body. It's a good thing "we are on speaking terms" (my body and I). I totally ripped that quote off of Fangirl.

I'm starting to be "on speaking terms" with my body also. We aren't quite there yet

Hmm is your goal to lose or maintain weight Bree? (hope you don't mind me asking).

Not at all. It would be nice to lose another 10 pounds. I've lost seventy, sixty the first 6 months and LCHF.

Hmm well if you are near your target weight, perhaps due to losing quite a lot of weight in six months or so, your body is probably just functioning better (less insulin resistance perhaps?). Or perhaps your body is at a "plateau" and just needs more time (and more fat I think). Usually with less weight, you take in less calories to maintain (or so I have always thought) so I do understand your point. But if you had quite severe insulin resistance, then perhaps your body is just using what little carbs you are eating better, then it turns to burning more fat. If your body perceives it is in starvation mode, then it will try to conserve it's fat stores. So with that in mind, my guess is upping your fat intake may be the best options at this point. You may find once you have gotten past that plateau, that you can decrease the fats again if you want.
If you are finding it hard to eat more, perhaps you are taking in too much water or fibre. If you don't see much sun, you could be vitamin D deficient, which can decrease appetite. Anyway, I'm no expert, but this is the only sense I make of it.
