BEAUTY . . . thank you for a great response. Yes, I agree "Gluttony, over-eating due to an eating disorder, and sugar/carb addictions are three different things."
I look at it this way: There are four groups of people when it comes to low carbing.
Group 1 has no interest in it. They eat whatever they want . . . carbs, fat, protein, etc. Includes most Americans.
Group 4 are the committed low carbers who have reached a desired weight or have curbed their appetite sufficiently to be making easy progress towards weight loss. These folks can take short vacations from low carb (like holidays and cruises) and then go right back to low carbing because they are mentally COMMITTED.
Group 2 and 3 are the On Again/Off Again low carbers . . . a.k.a. OA2s or Intermittent Carbers (ICs).
Group 2 people use low carb short-term to achieve some goal then go back to their old ways. This includes figure athletes, people getting ready for a wedding or to go on a trip. A lot of military people use low carb intermittently. For example, PT test coming up, promotion board or time to submit a new photo. They shrink and get lean then go back to doing what they were doing.
Group 3 is the crowd of people who are wanting to adopt low carb as a lifestyle and are in that first one or two months . . . and/or maybe their fourth or fifth attempt to adopt the lifestyle.
Group 1, 2 and 3 is where I see the problem of over-eating for some other reason besides nutrition.
I've read theories about FOOD WEIGHT being important . . . i.e., people must consume a certain weight of food to be satiated. Others talk about volume or the "warmth factor."
The gentleman I described in my post (I believe) still eats large quantities of low carb because he needs to feel full. If he stays on a low carb diet and joins Group 4 that fullness should come faster. (That's how it worked for me.)
The problem is that many Group 2 & 3 folks believe low carb is a panacea that allows free-range overfeeding, grazing . . . whatever you want to call it.
The point I would like to emphasize is that Group 2 & 3 folks need to be VERY calorie conscious.
