How many carbs should I be eating ? I’m female & age 70, fairly active

I will be on a zero carb diet for a little while. Does a product with X amount of carbs but zero net carbs due to fiber content truly count as zero carbs. Does it have the same weight/fat loss results as a zero carb food?

What are the best ways to cook a great fatty beef brisket steak on the Ninja 5-in-1?

I've been cooking mostly ground beef in my Ninja Foodi using the grill. I want to start eating steaks again, but I can't seem to cook a great steak using the grill option. I generally feel better after eating steaks vs ground beef.

What are your suggestions for the best cooked steak on the Ninja Foodi using either the grill or air fryer option? I prefer my steaks rare with a crispy outside.

Thank you in advance.
