Carbs even mixed in water can spike insulin to fat forming levels. As I said, it is to be avoided if you are doing extremely low carb diet, to lose body fat.
You can, as I do, take digestive enzymes with each meal. Ox bile is especially good for digesting fats. Plant based fats should be avoided, as they are the most indigestible fats. I only use EVOO and EV sesame seed oil, sparingly.
There is no reason that an ecto requires carbs.
Because they're good and satisfying. I'm an ecto and life would suck without donuts, pizza, ice cream and fries. There's a reason why carbs are part of the macro nutrient profile. Never made sense to me to completely eliminate a macro nutrient permanently. But I do believe it's true that if you want to lose weight fast zero/low carbs are the way to go. Just losing the water alone helps you make weight. But that's from what I've heard as I've never been on low carbs let alone zero carbs diet. If you want to lose weight you have to be at a caloric deficit no matter what you are eating or not eating.
I eat pretty healthy but not a week goes by where I don't have pizza -- a pan pizza. I love the thick crust. Also, I eat about six McDoubles and fries over the course of a week. Go through a half gallon of ice cream and just can't resist getting in a half of dozen doughnuts a week. Just finished a 5 oz bag of honey dijon kettle chips going through this thread. I get most of my carbs at night just before I go to bed. TA is the same way. The secret is that our caloric expenditure matches our caloric intake. Unlike TA, I don't believe the calorie in/calorie out theory. Eating 100 calories of celery is going to be processed differently than a 100 calories of cheetos. So the calorie "In" is not the same calorie once it's "In" the body. But still the bottom line is whether you are at a caloric deficit, surplus or equilibrium.
You don't have to be a bodybuilder to post a pic. Just a pic of your waistline will tell us all we need to know. I don't consider myself a bodybuilder per se as I'm not trying to build bigger muscles. But I'm pretty active and always stay below 10% (more like 8%) on a carb rich diet. I burn off those donuts and pizza and would lose weight if I didn't eat "junk" food because I am an ecto. I need those carbs.
I won't hold my breath waiting for you to prove and back up your talk.
