I don't think that's "yo-yo" dieting. Even Dr. Atkins recommends going back to Induction whenever necessary. 50 gm. of carbs is not high at all, for instance it's just Phase II on Protein Power, on the Schwarzbein plan it's 15 gm. per meal and a number of vegetables (non-starchy) are considered "free" so translated to "Atkinese" it would be way more. As long as a person doesn't go back to the bread, pasta & pastries, adding more healthy carbs cannot be classified as "yo-yo"
