    I have to say I appreciate your explanation about hunger. Thanks for sharing, PK.

    By the way, PK, would you have any "hormonal" explanation regarding the sensation of, you know, "being hungry, or feeling like eating something sweet" ?
    My mother knows a bit about health and lifestyle, and knows about the PB. However, she's wondering why at times when she feels stressed she wants to get some sweeties (dark chocolate, honey, sometimes almonds, ...). Are you technically hungry when your nervous tension falls abruptly ?

      Chocolate is a tricky one. One of the principal ingredients in chocolate is cocoa powder. Dark chocolate in particular contains high concentrations of cocoa powder. One of the contents of cocoa powder is beta-phenylethylamine (PEA). PEA stimulates the release of dopamine in the brain, and PEA itself is produced naturally by the brain during states of emotional euphoria. It is now established that concentrations of PEA are greatly increased in brain following administration of monoamine oxidase inhibitor (MAOI) antidepressants.

      Effectively, then, when you crave chocolate, you may be self medicating by administering an anti-depressant. Cravings generally reflect an underlying physiological need, and you may also be craving chocolate due to a magnesium deficiency:
      Chocolate may be used by some as a form of self-medication for dietary deficiencies (eg, magnesium) or to balance low levels of neurotransmitters involved in the regulation of mood, food intake, and compulsive behaviors (eg, serotonin and dopamine). Chocolate cravings are often episodic and fluctuate with hormonal changes just before and during the menses, which suggests a hormonal link and confirms the assumed gender-specific nature of chocolate cravings. Chocolate contains several biologically active constituents (methylxanthines, biogenic amines, and cannabinoid-like fatty acids), all of which potentially cause abnormal behaviors and psychological sensations that parallel those of other addictive substances.

      I'm not really clear on the underlying mechanisms that associate cravings with biological deficiencies, but there is definitely a relationship there. Sorry to be a bit vague here, but I cannot find the studies just now, but there have been studies performed where rats were made surgically deficient in an essential nutrient by removing organ(s) responsible for metabolizing the nutrient. When these rats were presented with feed enriched with the nutrient and non-enriched food, all of the rats that had been operated on ate only the enriched feed. By doing so all of these rats lived a normal rat life span.

      Rats that have not undergone the surgery will preferentially eat the non-enriched food when given the same choice. The inference from these studies is that somehow, the underlying deficiency manifests as changes in the way the rats perceive the food, ie in how the food tastes to the rats, and it is likely that the deficiency induces the equivalent of a rat "craving" foods high in the deficient nutrient.

      If I can find the original studies, I'll post them here.

        Hm... 5'6" - sorry, 5'6.5 - and something under 9 1/2 stone. Are you really overweight?

            Of COURSE she's not! Her BMI's 21. She loses 10lb, it'll drop to 19.2 - and you think I have BDD!!

            No idea what I weigh these days. My scales are giving me a right old giggle - I was nearly 10st nekkid this morning! Now, I know I gain a bit when Auntie Flo's due a visit - but NOT nearly 1.5st!

            I don't care anymore. I'm not overweight, my clothes fit. I don't look too bad (losing 12 stone doing silly things like MRP diets does things to a body - like leaving me with yards and yards of loose skin that doesn't appear to be going anywhere in hurry...). This is why I think I'm fat - it's not fat, it's flabby skin. That pic (if anyone saw it, black trews blue top) was me at around 15 stone - I'd already lost about 5st by then.

            Well, my body doesn't look too bad - shame I can do bugger all about the face. I thought that, when I gave up the soy, the hair would lessen (it did for a bit, now it's back stronger, thicker and coarser than before. I just wish I knew why...). How can I feel good about myself when I look ugly...?

              Yup, scales are funny. The trick with mine is to get on, get off, get on again - 'lose' 5lb every time. (Well, not indefinitely, but you know what I mean.)

              1) Ugly? Sez who? and 2) what's that got to do with the price of tea in China, anyway?
              Grizz has a recent post about PCOS here.

              Sorry for the minor derailment of your thread, Snowy. Please ignore... apart from the bit about weight and not necessarily needing to lose any. Eating Primal is about reaching a state of optimal health, which means optimal weight, which is not necessarily as skinny as you (/we/I) think you (/we/ I) 'ought' to be.
