Believe me Mrs Pugwash - I've been there. Followed the low-carb, higher protein to the letter - the minute I added back in the highly addictive grains and starches I couldn't stop and the weight piled back on (not to mention the wild BS swings!).
If you are able to limit it to a small amount then good on you, but I, like many Diabetics, have major problems with carbohydates.
What I am learning is that a craving for carbs is often the body's way of trying to balance brain chemistry. The brain can use either glucose, or amino acids for fuel, like L-glutamine. If it can't get enough of the acids then it will revert to glucose although it is an inferior fuel (from what I understand, L-glutamine is also used for cell repair). Strong signals are asking for fuel and we provide it, but it is not always what it is actually asking for!
So now I am concentrating on making sure I am giving my body high quality fuel - veggies, fruits, meat, fish, nuts and fats. There are millions of people living very well - and healthily on no grain diets all over the World. I won't die without them.
A/C - I have just picked up that apparently a lack of vitamin B1 and Zinc can suppress appetite. Apparently anorexics have this problem because they obviously eat so little. Perhaps you need to up your calorific intake more with a bit extra fats and protein. B1 is in yes, pulses and grains, but is also available from seeds, meat, eggs and veggies. Zinc is in eggs, meat and things like sunflower seeds. Apparently we Brits tend to be quite deficient in zinc.
It is a natural immune booster too. I remember when I was working for a large bank and spent 6 months with a virtually permanent cold that seemed to be going around all the time. Eventually I started taking zinc and never caught one again all the time I was there. Amazing.
