Keep in mind that Indigo-3G is present in the blood and doing its thing for at least 6 hours per dose, but it also has long term effects. People stop taking it after a period of time and can still eat more carbs than before because all those underlying issues have been repaired, so to speak.
But there’s no hard and fast rule about carb intake. Some former low carb, keto fans have bumped up to a couple of hundred grams per day, and then you have some people topping 500. Everyone is different, but the key is to find that limit, which is typically higher than most people think. So, how many carbs do you consume? As many as possible without noticeable fat gain (if the goal is to build muscle and lose fat.)
