Eating too much ?

So

Since I’m on the gd diet I feel like im replacing the extra carbs id be eating with more meat or fats. Ofc i eat veggies too but it takes more to feel full. I worry #1 I will have heart problems or hbp from all this extra meat and #2 baby will still be big from all these calories and fats.

I had gd with first baby too but it was diagnosed much later so I didn’t have to deal with it for a long time.

Also im normally thin I just eat a lot. 5’3 110 prepregnancy.
