Week Seven on Keto: Why Month Two Feels Different, and When to Start Cutting Fat

2020-02-16

In this recording

A 26-minute Live from February 2020, posted privately inside the group during the "RebootMeKD" program. Some members had started tapering in early December, and the full group had restarted on New Year's Day. This was the middle of week seven. The broadcast ended early when the video feed turned into a pink screen.

[0:52] Why we count by weeks. Keto is fundamentally a calorie-based diet. The question is what keto adds.
[1:47] The mechanism as I explained it: insulin ties up lipase, the enzyme that breaks down fat, so fewer carbs should mean easier access to fat stores.
[3:24] Ketones, the three ketone bodies, and the mitochondria adapting to use them.
[4:55] Adaptation timing: as early as day 15 to 17 for some people, but in general three to eight weeks.
[6:30] Month one on keto is a regular diet, but harder, if you try to restrict calories and carbs at once. So in month one, focus on carbs only.
[10:18] Keto vs a low-calorie group, month by month: keto starts worse and gets better. The low-calorie group keeps grinding on willpower.
[12:27] What still slows both groups: cultural eating, break-room donuts, stress eating, partner eating, eating that isn't driven by hunger.
[15:34] Why I don't hand out one meal plan. My kitchen, fridge and schedule aren't yours, and some members were eating out of a truck cab.
[18:08] Week seven, two paths. Hunger is handled and progress is fine, or progress is slow and it's time to plan or track.
[19:41] Keep protein at 80 g or more and keep carbs low, but don't chase zero. Keep the greens. If something has to come down, it's fat.
[21:15] Fat floor: about 30 g a day, which almost nobody misses. Members reported steady progress around 70 g. I'd been recommending 77 g on an 1,100-calorie plan.
[22:18] Lower fat is fine down to about 50 g. Below that is being extreme.
[23:15] My week-seven advice: trim 10 to 20 g of fat from your tracker or meal plan and see if it's manageable.
[23:47] The planned topic, keto on the go, was cut off when the feed turned into a pink screen.

Watching this in 2026

The shape of this Live is the shape of how I teach keto. Month one, count carbs only. Let adaptation do the appetite work. When hunger comes down, keep protein where it is, and the thing that comes off the plate is fat (live UIKT6147). I'd said a version of that since 2017. Stop pushing fats once you're adapted (video NUJNFG6lLWw). Don't restrict calories in month one, and look harder if hunger lasts past week six (video 7Aixw4uRksI).

What I like most here is the honesty about who's watching. I said I hesitate to give a single meal plan because I don't have kids, I'm not married, and I'm not living out of a tractor trailer (live UIKT6147). That's still the right instinct. The rules travel. The menu doesn't.

The claim worth unpacking: "fundamentally a calorie-based diet"

I opened by saying keto works the same way all diets do, through calories. Its advantage is that hunger drops, so the calories come down on their own (live UIKT6147). That's the same argument I made in 2017 about adherence (video 9AGpKAfs3Yk). The trials on the ketosis evidence page mostly back the calorie half:

In DIETFITS, 609 adults on a healthy low-fat or a healthy low-carb diet lost 5.3 kg and 6.0 kg at 12 months. The difference wasn't significant (Gardner et al., 2018). The low-carb arm there was moderate, not ketogenic.
In a metabolic ward with calories held equal, 17 men switched to a ketogenic diet. Energy expenditure rose by about 57 kcal a day, and body-fat loss slowed after the switch (Hall et al., 2016).
In another ward study of 19 adults, cutting fat removed more body fat per day (89 g) than cutting the same calories from carbs (53 g) (Hall et al., 2015).

In the Live I also floated the idea that bodies "run cooler" on a high-carb diet (live UIKT6147). The ward studies don't show a large metabolic advantage either way. Where the literature and my argument agree is the practical part: if a diet makes eating less easier, it works better for the person on it.

The mechanism needs a footnote too. The way I put it, insulin binding lipase and ketones being the "constituents of a fat molecule", was a simplification. The ketogenesis reference describes ketone bodies as made in liver mitochondria from fat, with the process regulated by insulin and glucagon (StatPearls, Ketogenesis). The direction I described, less insulin and more fat use, matches that. The detail I gave doesn't. More in insulin and fat storage.

The line that holds up

I described myself as someone on the internet who "points to articles", not a medical professional (live UIKT6147). In the same breath I said to run changes by your doctor, especially if you have any condition. That goes double for anyone on diabetes or blood-pressure medication. When carbs drop, doses can need changing, and that's your doctor's call. See keto with medication.

Key points

Month one: control carbs only. Trying to cut calories at the same time makes keto a harder version of a normal diet.
Most people adapt somewhere between week three and week eight. After that, hunger and energy usually feel different.
Non-hunger eating (work treats, stress, partners, kids) slows everyone, keto or not.
At week seven: protein at 80 g or more, carbs low but not zero, greens kept. If progress is slow, trim fat by 10 to 20 g.
Don't drop fat below about 50 g on purpose. Almost nobody gets under 30 g without trying.
In trials, weight loss on low-carb and low-fat diets ends up close when calories end up close (DIETFITS).
