Ok, I've been dieting enough years to know that weight will fluctuate no matter how clean you've been eating. Since Sept 6, I've been following the SB diet until this past Saturday when I started eating vegan. According to the menu creating website I've been using (NutritionMD.org), My calories average 1100-1200/ day. This morning, however, I woke up and was greeted by a 1/2 lb increase in my weight. Someone in my office suggested that carbs can cause you to retain water--anyone know if this is true?
