Let's say somebody is a real fatso of about 250 lbs and 40% bodyfat. Our hypothetical dieter also doesn't get any exercise ever, and doesn't intend to. What happens when we use the following macronutrient calculator to find out how much protien and carbs this guy needs to be on a diet. https://www.muscleforlife.com/macronutrient-calculator/ Well, if you put the numbers into this calculator this dude needs 1622 calories a day, 300 grams of protien, and 0 carbs. Why 0 carbs? Because he doesn't exercise at all, and is so fat that the only way to hit his 1622/300 calorie/protein goal is to eat nothing but protein. Now suppose this guy decides to get 5 hours of exercise per week.
Well suddenly, he needs 85 carbs and 1990 calories a day to be on a diet. His carb and calorie needs shot up, because he started exercising. Protein remained the same.
Now, what happens if this guy goes down to 200 lbs with 20% bodyfat? Well, at this point, even without exercise he needs 1708 cals, 97 carbs, and 240 grams of protein a day. If he exercises 5 hours a week then his carb and calorie needs shoot up to 2096 calories and 194 carbs.
What happens if this same guy drops down to 10% bodyfat, at 180 lbs, and starts to go into a bulk phase, with regular exercise? Well now he needs 426 carbs a day, 2911 calories, and 180 grams of protein.
My point is that how many carbs you need a day depends on your body composition, and how much you are exercising. People that find success on the low carb/no carb diet are usually seriously overweight and sedentary (so they need no carbs), or unintentionally sneaking 70-85 carbs into their no carb diet, turning it into a proper diet on accident.
P.S.
Pemalite said he is on a no carb diet and bulking, but bulking is completely different than dieting, and I have no clue about the specifics of his regimen.
