Hello everyone, I have IR and prediabetes. My doctor suggested to me to go on LCHF diet with Metformin (3x750ER). Now I´m on paleo diet, my daily intake of net carbs is about 70g. I´m feel really well (I don´t take metformin yet) but have a question because recently one dietician told me that we need glucose for our brain and body, nervous system (min. 120g of carbs per day) so only high carbs is good for us or a keto diet, according to him all diets between 50-120g of carbs are bad for our brain and muscle, our body doesn´t have enough glucose to function properly and doesn´t have ketons to replace glucose flue. Is it true or myth? I read something similar on google call ¨low carb limbo¨ that is bad for us and we should stay away from this (again only keto or high carb low fat is good) but is what, for example, Mark Sission from BluePrint Paleo call ¨sweet spot¨ (50-100g of carbs per day) so now I´m confused.
Also, can I take metformin on LCHF with average 70g of carbs per day? I don´t want and I´m afraid of returning to high carb, when I was eating about 150g of carbs per day, one day, suddenly I starded gain weight and I gained 30kg in almost one year and I was diagnosed with IR and prediabetes … On 70g of carbs I don´t gain weight, I feel ok, I have energy and don´t have to sleep all day long after meals but I´dont know how it will works with metformin and what about my brain and other organs haha on this amount of carbs because I´m not in ketosis and I´m not on high carb diet, I´m on low carb limbo-sweet spot Is it bad or no?
