I assume you are doing induction since you've been on Atkins for 3.5 weeks. If so, you've got to cur out the nuts, snack bars, and meat loaf at this point. Make sure you are drinking at least 80 oz. of water per day. Nuts should not be added until you get to OWL, this goes for the snack bars and meat loaf as well. Make sure you are eating eggs, meat, and cheese (4 ox or less) per day. Even the Atkins shakes are not good for induction.
