Hi Drew!

It's because it's assumed that you will also be getting carbs from some of the other foods allowed on induction such as eggs (0.6 grams of carb each), cheese (1 gram of carb per ounce), cream (about 0.5 grams per tablespoon), coffee (about 1 gram per 8 oz. cup) and artificial sweeteners (1 gram per packet). If you factor in all of those are are still short of 20 grams of carb, go ahead and eat more veggies. I have a feeling that not too many of us got overweight eating too much broccoli, green beans or lettuce.
