I honestly think that 50g is a bit excessive. <25g with protein restriction does it for me. Doing some HIT every few days helps too.

i don't even hit ketosis at 50g a day! and then you have to watch your protein to make sure you don't start making glucose out of that. i think i hit "the fat burning beast" state once for about 2 weeks and i have no idea what i did right; i keep crappy records :(

lots of unknowns here.

1) What is your current diet? If you are eating SAD then this will take a few weeks to a couple of months.

2) How many carbs do you currently eat? Lot's of carbs and your body may be less "fat-adapted"

Typically you are always creating and using ketones for energy, ketosis is typically defined as B-OHB levels below 0.5 mM. To get there would take a day or two, but there might be a bit of the "Carb Flu" before you are fully taking advantage of the ketones.

There is no absolute answer. It depends on a number of factors:

  • Your intake of carbs prior to this experiment
  • Your fat intake as a percentage of calories during the experiment
  • Your gender
  • Your age
  • Your personal biochemistry (genetics and epigenetics)

For example, if you've been eating a high-carb, low-fat diet, and you suddenly shift to a low-carb, high-fat diet, it usually takes 2???3 weeks before you start getting into ketosis, with full adaptation to using fats for fuel happening in 4???6 weeks. For another example, if you've been eating only 100g of carbs/day, and you start eating 50g/day, while increasing your fat intake (to prevent your body from thinking there's a famine), ketosis could start in 1???2 weeks. Both of these examples are hypothetical, because the other factors (age, gender, personal biochemistry) all influence the outcome.

If you provide some more information, folks in this community might provide a more accurate guess, but it would still be a guess.

The answer is: longer than you would if you restricted your carb intake to 25g a day.

Check out Jimmy Moores blog. He has been doing some self experimentation lately and is 4-5 months in now on VLC. Also, Peter Attia is a great resource. He maintains VLC and believes it is the best path to optimal health. His blog is pretty much dedicated to it.

I think you have to do just that, experiment. Everyone is different and can handle different levels of carbs. Age, gender, metabolic health, weight, size, possibly even blood type are just a few of the factors that could affect the variation in the level of carbs needed to go ketogenic.

If you want to figure it out, I suggest experiementing. Buy some ketostix, track your carbs carefully and figure out your sweet spot...
