this is true, fructose replenishes liver glycogen and not muscle. liver glycogen levels are also critical in keeping a good blood glucose level and its used for brain and other sources of the body. muscle glycogen is used only for very high energy expenditures and it replenishes itself over night. unless you are lifting at 90% with little rest periods for 2 hours, you wont deplete it significantly..and whatever you do deplete will restore itself. so unles you have another training session that day, it is not critical to replenish the glycogen.
its a very old misconception that you will be all weak and flat. complex carbs dont make you strong. in fact once your glycogen stores are full, the carbs from complex carbs get stored directly as body fat. if you are eating complex carbs all day, you are also carrying a s*** ton of water considering you are 240. for every excess gram of glycogen you store 3 grams of water. carrying water around in your muscles is useless, its not real weight. I definitely saw that in myself, once i stopped eating complex carbs and went completely paleo I lost around 10 lbs and it was pure water because i didnt lose any strength and only got more cut and shredded. i also cut up completely to an 8 pack, where before I was so bloated from grains I felt like i was pregnant.
as far as energy goes, I have tons of it and I power through 4 two hour mma/bjj sessions every week and lift 2-3 times. i eat only fruits and vegetables as far as carbs go.
complex carbs are just empty calories in my opinion. they are starchy and spike your blood sugar like a motherefffr. so you get insulin spikes throughout the day which leads to fat gain and diabetes. there are no vitamins in bread/pasta/grains and very little minerals arent absorbed because of phytates. plus all the issues with gluten and un needed amounts of insoluble fiber that just grind on the intestinal lining.
not trying to start any arguements here, just throwing my 2 cents in. perhaps if you are training super hard then complex carbs have their place, but only Post WO because any other time you dont benefit from them at all.
