Hi MissThomas, the GI diet focuses on carbohydrates and controlling blood sugar. It concentrates on whole grains, beans, pulses, and fruit and vegetables. it was originally devised as an eating plan for diabetics to help them control their blood sugar. Personally i'm not diabetic but from following a gi diet plan, I am finding it is a great way to control cravings and that sugar crash from eating the wrong foods which makes me eat again "for energy".
The meals tend to be big on flavour but in a healthy way and i am finding i'm not hungry. I did look in to joining an online diet plan but my husband had a look on the internet and found loads of meal ideas for free which i've made in to my own plan. It is based on a point system and has "free foods" which is easy enough to follow. I don't follow the diet recipes religiously but I stick pretty close and it says to limit things like coffee and other caffeine containing things , which I find a bit difficult, but I am aware that they can make me want to eat so I try and have coffee etc around the time of a meal/snack.
I track my progress on an app and the diet plan probably allows for about 1200 calories, my personal allowance is a bit more but I try and stick low and allow the extra for bad days, it doesn't seem to be a problem as I feel quite energetic/full.
