Hi,

I red something like :

-- "if the glycogen stores + muscle stores are full and you eat additional carbs, they will be stored as bodyfat".

Once a week I do a hyperfeed where i consume tons of carbs.
(round about 50g carbs pre-workout-shake + 50g carbs postworkout-shake + 330g carbs (~500g oats) 1h after my workout)

- do i have to consider something like : too many carbs -> all stores are full -> carbs will be stored directly as bodyfat

additional info : (i don't know if it makes and difference)
age 21
height 5 11
weight 182
bodyfat 12%

thanks

I can't be completely sure, but I think I read somewhere that 500g CHO was max glycogen storage.

-STUDY-

Glycogen storage capacity and de novo lipogenesis during massive carbohydrate overfeeding in men

KJ Acheson, Y Schutz, T Bessard, K Anantharaman, JP Flatt and E Jequier
Institute of Physiology, Faculty of Medicine, University of Lausanne, Switzerland.

The metabolic balance method was performed on three men to investigate the fate of large excesses of carbohydrate. Glycogen stores, which were first depleted by diet (3 d, 8.35 +/- 0.27 MJ [1994 +/- 65 kcal] decreasing to 5.70 +/- 1.03 MJ [1361 +/- 247 kcal], 15% protein, 75% fat, 10% carbohydrate) and exercise, were repleted during 7 d carbohydrate overfeeding (11% protein, 3% fat, and 86% carbohydrate) providing 15.25 +/- 1.10 MJ (3642 +/- 263 kcal) on the first day, increasing progressively to 20.64 +/- 1.30 MJ (4930 +/- 311 kcal) on the last day of overfeeding. Glycogen depletion was again accomplished with 2 d of carbohydrate restriction (2.52 MJ/d [602 kcal/d], 85% protein, and 15% fat). Glycogen storage capacity in man is approximately 15 g/kg body weight and can accommodate a gain of approximately 500 g before net lipid synthesis contributes to increasing body fat mass. When the glycogen stores are saturated, massive intakes of carbohydrate are disposed of by high carbohydrate- oxidation rates and substantial de novo lipid synthesis (150 g lipid/d using approximately 475 g CHO/d) without postabsorptive hyperglycemia.

sooo to check if i get this right...

if i eat about 50g pre / 50g post + 350g post (~400g) and my storage is about 500g + i absolved a serious workout (round about 2h incl 20mins cardio) which also deplete some of my already stored carbs

I do have enough "space" for the ~400g carbs and I'm totally fine/safe .. right ? :)

I don't know if i get your replys right .. because my english isn't the best .. so I would be happy if someone could give me an "ok, everything is fine" or something like that ..

thanks :D

I'm pretty sure that the study was done on people on Keto diets with full glycogen depletion.

and that means exactly what considering my question? I don't get it ...

why can't i just get an answer like "everything is fine" or "that way too much carbs, they will be stored as bodyfat"

Remember not all carbs are used for muscle glycogen, liver glycogen and the brain are major consumers as well

you eat 330 g cho of just oats?? you need to live a little man. lol

I would unleash hell in my toilet if I ate that much oats

i eat more carbs from oats then that and let me tell you it is awful for my toilet at least, i don't mind.

this whole thread is irrelevant because eating carbs while glycogen is full does not result in net fat gain.

Are you sure? got a study/proof or something like that about it?

I mean .. this would be wunderful :D
