i think the low to ZERO carbs is the best way to burn fat and the quickest...i do feel juice is needed though, even though in theory this diet is supposed to preserve muscle, the lack of fullness and water retention you make you look and feel small...so as they say TEST IS BEST for a guy that is....and on ANY diet for that matter...i ONLY juice when i diet...i EAT when i want to gain size.
on a side note, a friend of mine, a national level competitor, quite famous, has been in many ads for universal nutrition...he takes 2gms of test when DIETING and maybe 1gm when gaining...too many people do it assbackwards and wonder why they lose size when they diet.
anyway back to the diet... i used to take maybe 50gms of dextrose and or maltodextrin pre and post workout....soemtimes i had that pre bottled stuff from worldwide nutrtion...has 35gms of whey isolate, and i think 40-50gms of pure maltodextrin. other tricks i used to do (not anymore) was take in mayb 75-100gms of glucose post w/o with some FAST acting insulin (humalog)..very dangerous thing to do but if done right (most do it wrong) u will be fine and be back in ketosis within 1hr after post carb drink.
also i would do small doses of insulin after my one big carb day every 10 days...about 2-3ius every hour until i was recording ketones on my ketostix... the 2 problems with insulin and low carbs is....you can get fucked up bad...like anytime you use insulin..but moreso on low carbs....you can fix this very easy...if u feel a crash just drink a tons of carbs, within 20 seconds you feel fine..but guess what...you just fucked up the diet and wont hit ketosis for another day or 2....so its very very tricky.
dont be stupid and try to fight off the crash with no carbs, its not fun to see white snow as we call it in ur eyes and feel like ur in a dream and ready to pass out.
