Lac? Lactose?

One meal a day can work fairly well, with Atkins food choices. My Dad has digestive issues, switching to one large meal a day gives him less acid reflux than a snacking pattern.

There's a sticky for Atkins Induction in the Atkins section of the forum, in case you need to familiarize yourself more with initiation of the diet, and take the "ish" off of Atkins. I'm not pushing for you to do this understand, since I don't really know how familiar you are with low carb plans to begin with.
