No way that’s 50g of carbs. They started with 150g dry pasta and the serving they plated was less than 1/5th of it. I’d be surprised if there’s 20g of carbs in that serving.
50g of carbs per "meal" are only enough if you eat 10-15 meals per day.
Or if you get most of your calories from fats and proteins.
And then you wonder why your triglycerides are screwed eating 500-750g of carbs a day
