How many carbs would offset the positive fat burning you get when you eat a high fat moderate protein breakfast?
Assuming you’re sticking with a ketogenic diet from this question. I’d keep carbs at any meal to a minimum when doing keto and breakfast is no different. If you’re just doing a low carb diet it would depend on a few factors but I’d say a general rule would be to stick to less than ~20g. There’s not really a specific threshold for your question as that can be influenced by several variables, so the takeaway here is to just keep carbs to a minimum.
