Hello guys,,
I'm on a low carb metabolic diet, similar to atkins I think, although dairy, with the exception of cream in you coffee/tea, and fruit isn't allowed in the induction phase. They say you can have 20g of net carbs a day, is it necessary to hit that 20g mark? is it ok to be under???

That's contraversial, but I believe it is ok to be under. The 20gm are usually salad and low carb vegetables that provide nutrients and fiber.
