Well Vixter, that all sounds quite positive. Can’t really comment on the blood pressure monitoring and the recommended calories, as this came from a medical professional and she is obviously advising what she believes is the best course of action for your Mum.
Yes some carbs are better than other. As you know, on the BSD you are advised to avoid bread, pasta, rice, etc and anything containing sugars, because these are simple carbs and it is these that our bodies become addicted to and causes that familiar blood sugar spiking, followed by hunger. However things like lentils, chickpeas, beans, nuts, quinoa etc are fine as they contain complex carbs, which don’t behave in the same way.
Hope that helps – I’m sure others will offer up some additional advise soon. Good luck to you and your Mum and hope to see some positive results posted soon.
