Why Keto Maintenance Is Hard: The Psychology of Keeping Weight Off

2018-11-28

A 47-minute Facebook Live from November 2018, eating dinner on camera after kickboxing, with my dog wandering into the shot. The topic was maintenance: why so many people who lose weight struggle to keep it off. My argument was that the hard part is mostly psychological and social, not biological. Near the end I admitted that I'd spent the whole live describing problems and hadn't solved any of them. That's worth knowing before you watch.

In this recording

[0:02] Disclaimer first: I'm not a licensed professional, involve your doctor, take what is useful and discard the rest.
[0:46] Tonight is maintenance. Does one carb make you gain it all back? Can you never eat a roll again?
[1:49] Keto has three phases, introduction, weight loss and maintenance, and I like that it names maintenance as a phase at all. Someone who lost 50 or 100 pounds at about a pound a week spent two years or more in weight loss, around birthdays, holidays and weddings.
[4:25] Maintenance is a different diet: different meal planning, foods and macros. But I think the bigger problems are psychological and sociological.
[5:12] The people in your life. While you're losing, "I'm down 10 pounds" answers every critic. Once you stop, the old line "but can you keep it off?" comes out.
[7:17] I know there's research on metabolic rate, set points and hormones that can take a year or more to adjust. Still, my unsupported view: people fail maintenance mostly for psychological and social reasons.
[8:02] Scale-focused people lose their reward. Maintenance has no scale results. And a 10-pound regain gets noticed when a 5-pound bump during weight loss didn't.
[10:21] If your goal is 150, then 149 and 151 both feel like failures, even though your weight can swing several pounds in a day from water. That's a game you can only lose.
[11:54] People focused on the mirror may do better, since body composition can keep improving.
[12:42] The food changes. My rough numbers: maybe 35% fat and 1,100 calories in weight loss, closer to 70% fat and 1,700 in maintenance. That's like adding a whole extra meal.
[14:13] It's a new skill set, much closer to the intro phase. After that, pick a health metric (sleep, a cardio goal, a strength goal) and warning signs, and involve someone else, ideally your doctor.
[17:47] Self-image: you can still feel like your old self, and backsliding can feel like going back to your "true" self. When I was bigger people called me cuddly, and part of me misses being that guy. Don't compare your new self to your old one.
[22:30] Build in wiggle room. If you go up a size or two, go back to the weight-loss phase, get a bit under goal, and return to maintenance. You already know how to do weight loss.
[25:14] A viewer's question about tracking body fat and resting heart rate: give each metric a grade and a weight, and add them up into one score.
[29:35] How to fit in protein if you're used to fatty proteins: whitefish and tuna are very lean. Anything with more protein than fat impressed me. Bacon and eggs are about one to one; sirloin is leaner than ribeye. Or add a lump of lean protein to the meals you already like.
[35:17] In maintenance you go the other way: skin-on chicken, fattier cuts, cream and oil sauces, cheese. I said the research I'd seen suggests olive oil is the safest fat to eat in large amounts, and that coconut and MCT oils had moved some cardiovascular markers the wrong way.
[36:57] I got punched in the eye sparring before this.
[39:25] A viewer's taco meat with salsa, guacamole and sour cream: an excellent maintenance meal.
[41:24] Off topic: I was overwintering seven varieties of pepper.
[45:48] Looking back: I described the problems with maintenance but not how to solve any of them. Next time, solutions.

Watching this in 2026: I named the problem and stopped

I said it myself at the end, and it's fair. This live is a good list of why maintenance feels hard and a short list of what to do. The "what to do" I did give is worth pulling out:

Treat maintenance as a new phase, closer to the intro phase than to weight loss. You're learning again, and that's normal.
Swap the scale for other metrics, like a strength goal, resting heart rate, sleep or a clothing size, and decide your warning signs in advance.
Use a range, not a number. If 149 and 151 are both failures, you've set up a game you can't win.
Have a way back. If you go up a size or two, run the weight-loss phase again. You already know how.

The scale point connects to something I'd said in 2017 about comparing yourself on social media (FSOW0254). Here it's about the people in your own life instead of strangers.

Drill-down: the protein-to-fat ratios

The most practical stretch is the protein section. My test, more grams of protein than fat, is a simple way to spot lean protein. The evidence pages back up keeping protein up while losing weight: across 24 trials with 1,063 people, energy-restricted high-protein diets gave modestly more weight and fat loss and less loss of lean mass (Wycherley 2012). A review puts the useful range around 1.2 to 1.6 g/kg a day with about 25 to 30 g a meal (Leidy 2015).

On fats, the evidence pages don't compare olive oil with coconut or MCT oil, so I can't check that claim here. What they do have is the National Lipid Association's 2019 statement: low- and very-low-carb diets lower triglycerides and raise HDL, with a variable effect on LDL (Kirkpatrick 2019). If you're adding a lot of fat back in maintenance, get a lipid panel with your doctor, and see the guide pages on cooking oils and cholesterol.

If you take diabetes or blood-pressure medication, moving from weight loss to maintenance changes what you eat, so tell your doctor. If you have kidney disease, check protein targets with them first.

Then vs now

A year later I put the maintenance fat point more bluntly: for weight loss, fats are fats, but in maintenance you'll want to choose them for longevity (live FPMJ7326). That's this live's olive-oil advice, without the specific oil.

Key points

Maintenance is its own phase with different food and different skills.
The hard part is mostly psychological and social: no scale wins, critics, old self-image. That's my view, not a study.
Use a weight range and non-scale metrics; decide warning signs in advance.
If you regain a size or two, go back to weight-loss mode. You know how.
Protein test: more grams of protein than fat. In maintenance, add fat back.
