Lazy Keto, the Original Recording: Count Carbs, and Where I Took Tracking Later
This is the original camera file of a video that's already on YouTube. The words match the upload of What is lazy keto, and do you really need to count calories? start to finish, and the file runs about 5 minutes 7 seconds against the upload's 5 minutes 12. The full write-up, with the metabolic-ward studies and DIETFITS, lives on that post. This page lists what I said with this file's timestamps, then follows the idea forward to a Live from January 2020.
In this recording
- [0:00] Today: what lazy keto is, whether it works, whether you need to count calories, and how closely to track. I said the question's time has kind of passed, because you need to count carbs.
- [0:20] Not counting can work if you really know your foods and you're willing to cut whole food groups, for example by not counting green-vegetable carbs on the assumption that the fiber covers them. Some people don't count anything. The standard scientific and medical recommendation is to count carbs.
- [0:55] Calories are a different question. I described studies where telling low-fat dieters to count calories made a big difference to how much they ate, while for low-carb groups who still counted carbs, counting calories made an insignificant difference.
- [1:30] My explanation: the diet works on insulin control and lets appetite and hunger regulate properly, so the calorie reduction comes on its own.
- [1:48] A calorie deficit is still required to lose weight; calorie counting may be unnecessary.
- [2:00] Most diets work if you can stick to them. In a lab you could control most people's weight by issuing all their food. Diets fail because people don't stay on them.
- [2:30] Every added restriction, like cutting dairy or counting calories, is extra work, and extra work makes people less likely to keep going. Groups that counted calories lost about the same as groups that counted only carbs.
- [3:10] The debate is dated anyway: every app I know that counts carbs also counts calories as a by-product.
- [3:28] If you don't know where carbs hide, count them. Nuts and pasta sauces can carry surprising sugars and carbs.
- [3:45] Lazy keto means one of two things: avoid the foods you know are a problem and assume you're landing at about 20–50 g of carbs a day, or track carbs but not calories. I said both are fine approaches.
- [4:05] If you're prone to cheats and exceptions, you may want to skip lazy keto.
- [4:22] Just asking people to track what they eat makes them eat better. I recommended tracking carbs and calories while you learn, so you can diagnose problems and get help. If you're busy and want it simple, the carb count is the one thing to focus on.
- [4:55] Sign-off: I love you guys, best of luck with your diet or weight loss journeys.
Then vs now: from 2017 to the 2020 reboot
Almost two and a half years later, in a long Q&A Live during the January 2020 reboot (write-up here), I was still giving the same order of operations, just with more detail on timing:
- Month one is for carbs, not calories. Answering someone who wasn't seeing the scale move in week three, I said that during the introduction phase I don't usually tell people to worry about calories. They're learning new groceries, snacks and recipes, and they aren't yet getting energy from ketones (live XRQH3246, [1:01:16]). That's the 2017 position with a reason attached.
- Apps. In 2017 the point was that any carb app counts calories anyway. By 2020 I'd soured on MyFitnessPal and was pointing people to Carb Manager, the group's favorite, though I hadn't tried it myself yet (live XRQH3246, [1:41:29]). I also said I mostly track to build meal plans for other people, because after years of reading labels I know what's in my food. That's lazy keto earned the long way.
- The calorie deficit didn't go away. In the same Live I did the plate math out loud: two 462-calorie plates for my protein, under 1,000 calories against the 2,000 to 2,500 I burn, about 2 pounds a week (live XRQH3246, [20:36]). Not counting calories never meant calories didn't count.
Watching this in 2026
I'd keep the core of this: count carbs first, tracking helps while you learn, and the simplest version you'll stick with beats a perfect one you won't. The part I can't back with a citation is the study I described at [0:55]; I didn't name it, and none of the evidence pages I use covers it. Treat it as my 2017 summary.
What the evidence does support is the line at [1:48]. At the same calories, switching to keto changed energy expenditure by only about 57 kcal a day in a ward study (Hall et al., 2016), and over a year healthy low-carb and healthy low-fat came out close (DIETFITS). Lazy keto works when your appetite does the cutting. When the scale stops, tracking calories for a week or two is how you find out why.
If you have a history of disordered eating, decide with your doctor or therapist how much tracking is healthy for you.
Key points
- Same recording as YouTube video LbPnm9T0oxc, about five seconds shorter.
- Lazy keto is either "avoid known problem foods at about 20–50 g carbs" or "count carbs, not calories."
- Count carbs while you're learning, especially hidden ones.
- A deficit is still required; counting calories is optional if appetite does the work.
- By 2020 I was saying the same thing: carbs first in month one, calories later if the scale stalls.
