Supposedly, according to DiPasquale. Although I never tested with keto strips. I guess that's the only way to really tell
But even then, so long as you're at 0.25g/btw in carbs or lower, it's still a very low carb diet and you should be fine. That's 50g for a 200 lb guy or 62g for a 250 lb guy.
I like the version Poliquin and DiPasquale came up with. The PWO carbs and carb refeeds every 4-7 days depending on carb needs and leanness. Also I believe he doesn't count carbs if it's coming from low carb veggies. Honestly, do you think if you ate 40g of carbs from spinach and broccoli that you'd not be able to lose fat??? It's neurotic and a waste of time counting these carbs. Then you see idiotic posts (not from people that are stupid...just from reading diets that are so hardcore on low carbs) about people saying "do eggs have too many carbs?"
Poliquin's guidelines for carbs are quite strict. He thinks if you're over 10% BF you're fat and should only use whey, glutamine, and glycine PWO until you aren't fat anymore. With that he recommends ONE carb *meal* every 5-7 days until you again are not fat.
Then in the 8-10% range he says 2 carb meals every 5-7 days, and you can start adding in PWO carbs.
In the 6% ballpark you can go up to 200g of carbs PWO if needed Key...IF needed. You don't need 200g carbs PWO when you do 5x5 3 times a week. And someone this lean can have a carb DAY every 4-5 days and not really even worry about the macros much. They can stay lean this way and gain muscle. Pays to be lean.
The diet for gaining weight is similar to that of losing fat...basically the difference is calories.
The whole idea is to get lean in the first place so you can take in the carbs to gain muscle properly and NOT get fat or damage health. Someone 20% BF isn't handling carbs properly and taking in large amounts is not only going to harm his body composition, but also his HEALTH. Get lean and you can take in more carbs in a healthy manner while staying lean.
Afterall, insulin is the most anabolic hormone. When you're leaner you control insulin better, and when you control insulin better, you can take advantage of the ability of carbs to build muscle better. Better muscle gains and less fat gain since you're lean and the muscles are a lot more insulin sensitive.
