I'm on keto & doesn't really follow phases like Atkins but we go pretty low carb. I'm at 20 carbs a day. As long as your under 50 I say you'd see progress, but that's just my opinion.

You could figure out your carbohydrate intake as a *percentage* of your total calories per day.
I used my basic metabolism rate (BMR) and total daily energy expenditure (TDEE) as guides
started out at 1800 total calories per day.

My beginning 'macros' were:
60% fat
20% protein
20% carbohydrate

I have since changed the macros to:
65% Fat,
15% protein,
20% Carbohydrates

I haven't cut my carbohydrates too much,
because I need to have a full belly of low-carb vegetables
like cauliflower, broccoli, and kale in order
to feel satisfied. If I don't make it to the carb allotment for the day,
I don't worry about it. I make SURE to eat the fat allotment.

The trick is to eat ALL THE FAT to feel satisfied,
and to use as fuel so that your body HAS TO transform
your fat reserves into the glucose your body needs for certain
metabolic processes.

Best Wishes!

I feel for you.
I have set my macros to 5% carb/ 70% fat/ 25% protein, but in real life all I seem to manage carbwise is between 15% to 30% carb, with less of the other two macros. What this means is I try to avoid carbs, but they sneak into my meals anyway... life happens. So I lose a bit of weight in the weeks when I go lower in carb consistently (yay) and then swing back up a lb or two in water weight when I eat more carbs. It is a seesaw.
I don't have that much weight to lose -- started out at 82 kilograms and have lost 5 over the past five months. I hope to lose maybe 5-8 more in the next year. I am not in a rush, and feel good on the lower carb intake. The day after a higher-carb swing I wake up tired and have to battle the carb flu again, so eventually I am hoping to finally learn from that :ohwell: ... but I seem to have a thick skull and tend to forget when faced with a bite of potato salad or pasta or cookie... What works best is when I remember to eat enough fat, which keeps the cravings away and ups my energy.
So you have to decide which way you want to go, and whether you can stick it out long enough. If you are a patient sort, you might be ok with higher carb levels, but you probably won't see fast weight loss.

From what I understand it only makes sense to have a very high fat diet if you are in ketosis. otherwise your body preferentially stores the fat rather than burns it. (and other benefits from high fat on ketosis are lost)

My understanding of the various metabolic changes that ketosis brings is hazy at best but that's basically my understanding.

I have high carbs for ketosis but am remaining in ketosis. so finding your personal level is out there. you don't have to stay at atkins induction levels to be in ketosis.

I don't understand how it works but I kind of wonder if timing of carb intake matters. it would make sense to me. your body does burn stuff once it's burned I am guessing it doesn't count anymore so it might be more of a limit at any given meal until it's burned.

I need some advice too... I'm eating between 20-30 carbs a day, but I am also watching my calories. I try to eat 1200 calories a day. The protein fills me up so much most days I don't make it to 1200. I am worried about messing up my metabolism eating <1200. What can I eat besides cheese that doesn't have carbs and less filling than protein?

Avocados work for me. Good fat & great source of potassium (more than a banana!). There's like 2 net carbs in 1 cup of avocado but they're fairly calorie dense (over 200 in a cup).
