If you want to follow a strict diet plan then what worked for me with GD is
- no sugar
- no cereal
- no flour based foods (bread, pastry etc)
- no mashed baked or roast potatoes
- no white rice
Basically no high GI carbs
I ate a lot of protein and fat - snacks were avocados, nuts, plain greek yoghurt, hard boiled eggs. Lots of meat, butter and dairy generally as well as veg. Had small amounts of low GI carbs like lentils, brown rice, pearl barley or new potatoes.
Didn’t go low fat at all, in fact eating carbs with fat lowers their GI which is good for GD. Some women did used to get advised to go low fat for GD but this is now outdated I believe.
I ate a a handful of nuts between meals which seemed to help avoid spikes.
Some people find they can eat certain carbs without getting a spike, this is trial and error and only possible once you get your testing kit.
I didn’t try going for a walk after/before a meal as I was working FT but have heard this can really help.
long post sorry! the key is, ditch the high GI carbs like sugar flour and mash. Eat more protein and healthy fat, and veg.
