Hi Andrew and welcome to the forums. Lowering carb intake can have a very quick impact on blood glucose. Many of us work on a lower carb intake than 130 grams - it's possible to do that and not to be hungry.
The solution for me is to eat more protein and fats - especially fats. This includes things like meat, butter and cream. I eat around 20g carb/day, one meal a day, and have done so for nearly three and a half years. This is mainly meat/fish/chicken with above ground veg. No pasta, bread, fruit, sugar, rice etc. The results are in my sig block below.
I would guess that what you're feeling is not really hunger, but a combination of appetite and your blood glucose levels starting to fall. Your system will have been running on elevated glucose for long enough to make it think that the high levels are "normal" and to then trigger "hunger" signs when they start to fall. Unfortunately, as the blood glucose reduction is what you want to achieve, it will take a while for your body to retrain itself to accept lower levels as "normal".
You might also be reassured to know that on this way of eating my cholesterol is the lowest it's ever been (it's not an issue for me but some people do think it's important).
