I have Adelle Davis’ 1947 book. She says eat salads first to fill you up. Basically reduces calorie density.

This Harvard study on T2D risk in low carb diet context looks interesting. For high animal fat/protein, up to 44% increased risk. For plant based, up to 16% reduced risk. I wonder if it’s SFA impact on muscle insulin sensitivity, which is one of the T2D drivers. pmc.ncbi.nlm.nih.gov/articles/PMC...

One potential solution in “will take more time” category is to solve the overweight/obese crisis, now ~73% of US. Excess calories drive excess weight & vice versa. It takes acres to produce calories. Solving health issue will reduce acres for energy dense crops (though increase acres for veggies).

Mechanized farming isn’t going away anytime soon. But can we reinvent it? Tractors at 10 tonnes per axle are considered “light”. Status quo is soil compaction + plant-free lanes for wheels. Why not mechanical walkers stepping on pads? Does planting milligram seeds with 40 tonne equipment make sense?

There are claims that Solein from fermenting knallgas bacteria (found in soil) is most land efficient way to produce protein. Why not see if a food chain rooted in knallgas microbes could go up soil trophic levels, like protozoa -> micro arthropods-> arthropods to produce insect based chicken feed?

I like the scenario of producing chicken feed from black soldier fly larvae feeding on organic waste. Seems like short path rotting matter to protein.

It just occurred to me… the spent malted barley grains from brewing are rich in protein, & are fed to livestock. Those cultures used for fermenting oncom should be tried out on spent barley byproduct of brewing.

Jim @zerothworld.bsky.social · 16/10/2025

We need to keep pushing ahead with food system innovation. One “new” source of food that’s virtually free & needs no more land is traditional Indonesian “oncom”. Just add spores to spent soy pulp (waste byproduct of tofu production) and voila delicious nutritious food after 36 hour ferment.

Last I heard, perennial rice in China had reached yield parity with conventional, and was more profitable because it was getting 4 harvests per planting. About 45 thousand farmers were growing it. The Land Institute spawned this and other efforts around the world.

I gather neonics are in food. How can we fix this mess? In an age of miniaturization & AI why are we still running 20 ton tractors on vast monocrop fields? How about fine-scale, highly diverse intercropping, via robotics? Lundgren says plant diversity creates insect diversity which suppresses pests.

420

Jim @zerothworld.bsky.social · 09/10/2025

Ouch! So neonics are terrible for pollinators. Continuous corn mono-cropping doesn’t need pollinators, since corn propagates via wind blown cross pollination. I guess we’d be better off with diverse intercropping that values pollinators & doesn’t use neonics.

I wrote a thread on the concept of “lace of rewilded field borders” as way of returning large extent, but modest area, of land back to Nature. Does this mesh with the subject of fixing continuous corn problems? bsky.app/profile/zero...

Extremely interesting. One comment on riparian buffers: The pawpaw tree is riparian, & is the host plant of Zebra Swallowtail butterflies, whose historic range is much of Midwest. Pawpaws could benefit this pollinator..

Thanks. Lots of good points about wellness grifters. For sound diet-health advice I trust Harvard Healthy Eating Plate guidance & other HSPH advice, all science based. Online diet-health influencers promise quick fixes & never acknowledge weight loss plateaus & regain common to all rapid loss diets.

Jim @zerothworld.bsky.social · 02/10/2025

The current rate of US overweigh/obesity is arguably a real health crisis. How do we fix it? Smart people within the food system need to focus more on solving this problem.

Jim @zerothworld.bsky.social · 02/10/2025

I’m fascinated with Kevin Hall’s discussions of how metabolism works & how it’s full of counter intuitive surprises. Online influencers pitching low carb never mention plateaus, how to break through them or counter backsliding; never post plots of daily weight over 2+ years for actual people.

When you see grams sugar per serving on label, multiply that by 0.8 to get the pounds sugar per year if you eat one serving per day. A kids flavored yogurt with 20 grams sugar eaten daily is 16 pounds per year. That’s 4 sacks of sugar. A kids gummy vitamin: one sack. Parents take note.

Finally, I speculate on whether the proposed novel meal portion model’s ability to fine-tune both weekly average meal calories and level of day-to-day calorie variance could yield insights on avoiding plateaus in a long-term weight loss program. 24/

Is it possible that this fluctuation level, by swamping the average loss rate, could obscure from the metabolism that a weight loss program is underway, helping to avoid plateaus? Perhaps the novel 400 : 600 portion model could provide a “control knob” to explore whether “noise” can be helpful. 21/x

Jim @zerothworld.bsky.social · 13/09/2025

For every 10-day moving window, I did a linear regression & found the standard deviation of weight data about the local trend line. On average, these day-to-day fluctuations were nearly 5 times the average loss within 10-day windows. 20/x

110

Jim @zerothworld.bsky.social · 13/09/2025

Based on my experience over some 850 days of weight tracking, graphical feedback, and a very gradual target loss rate, I suspect that variance may play a role in successfully staying on track with weight loss goals. 19/x

Jim @zerothworld.bsky.social · 13/09/2025

Thus, with the novel 400 : 600 portion model, one has control over both weekly meal (say, lunch) calorie total, and the amount of day-to-day ups & downs. It seems unclear whether greater or lesser day-to-day calorie consistency is better for weight loss success. 18/x

110

Jim @zerothworld.bsky.social · 13/09/2025

The novel portion model provides an actuator for tuning total weekly lunch calories. It may also provide a 2nd “control knob”. As it turns out, for most given calorie values, several distinct portion profiles will produce the same total weekly calories; but with differing standard deviations. 17/x

110

Jim @zerothworld.bsky.social · 13/09/2025

The app could give advice on frozen meal portion choices to help a person keep weight loss on track. This could accomplish calorie tuning without calorie counting, per se. One could, for example, just grab 1 or 2 of the app-recommended packet sizes from the freezer before heading out to work. 16/x

Jim @zerothworld.bsky.social · 13/09/2025

If the moving average weight lies above the target trend line, eat a bit lighter; if it dips below target, ease up on restriction. One could also adjust daily exercise calories burned to help stay on track with loss progress. 15/x

Jim @zerothworld.bsky.social · 13/09/2025

In the adaptive control approach, you log your pre-breakfast weight daily in an app. The app plots a 10-day moving average smoothed curve vs time, overlaid with a descending straight line with slope reflecting user target loss rate (e.g. -0.01 kg/day). This takes only a couple minutes each day. 14/x

Jim @zerothworld.bsky.social · 13/09/2025

This 400 : 600 model of frozen meals could play a part in an “adaptive system control” approach to weight loss along the lines of Walker’s 1991 “The Hacker’s Diet”. The ability to fine-tune one’s weekly lunch calories provides an actuator “control knob” to nudge the weight in desired direction. 13/x

Jim @zerothworld.bsky.social · 13/09/2025

If a person were to eat 7 of these meals per week (say, for lunch), eating 1 or 2 portions per meal, then the average calories per meal over the week could be any one of 29 values ranging from 400 to 1200, in increments of 28.57 calories. This precision is about the calories in 3 cashew nuts. 12/x

Jim @zerothworld.bsky.social · 13/09/2025

Suppose frozen meal products follow a standard where each meal comes in 2 sizes: a small size with 400 calories, and a large size with 600 calories. If one eats 1 or 2 portions chosen from these 2 sizes for a given meal, then the available calories for that meal are 400, 600, 800, 1000, & 1200. 11/x

The US is in the midst of an ever-worsening overweight/obesity crisis, with some 73% of adults having a BMI over 25. I believe that the multisolving frozen meals can play a supporting role in helping to tame this crisis by adopting a novel approach to the sizing of frozen meal portions. 10/x

Jim @zerothworld.bsky.social · 13/09/2025

It’s unlikely that commercial meal offerings could, at least initially, embody every problem-solving feature outlined here. Package QR codes could take the consumer to a site describing the virtues specific to each meal. This can potentially introduce people to unfamiliar food system topics. 9/x

The world is “drowning” in plastic. The envisioned multisolving frozen meals could use 100% plastic-free packaging. The French invented baking parchment paper, mid 19th century, by applying a safe acid wash to fiber paper. I assume a similar method could create a microwave-safe fiber meal tray. 8/x

Jim @zerothworld.bsky.social · 13/09/2025

The envisioned multisolving frozen meals could be sold in grocery stores. They could also be sold in refrigeration equipped vending machines in workplace break rooms, highway rest stops, inner city laundromats, and so on, adding to convenience. 7/x

Frozen meal offerings could strive to include regionally grown foods to as great an extent as possible, as well as de-centralize food production. This can minimize transport impacts (saving energy) & spread job creation across regions. 6/x

Meals could be tasty & embody sound health advice, e.g. Harvard Healthy Eating Plate guidance.

Ultra processed foods are widely believed to contribute to health problems. I believe that, with flash-freezing, frozen meals could duplicate from-scratch home cooking made solely using ingredients available at grocers; even ingredients that people would have recognized as food 1000 years ago. 3/x

Fall 2021 I did retrospective “what-if” numerical simulation on US COVID. I used daily new cases to estimate avg Re; vax data, efficacy, waning to get avg Ro estimate; boosted actual vax rate by x%; went in reverse to get idealized Re, daily rates. For some x%, cases dropped to 0 by September 2021.

Are there studies on efficacy of very gradual weight loss (3.65 kg/yr), daily weighing, plotting 10-day moving average, portion control and such to stay on track with - 0.01 kg/day target? Aesop’s lesson of slow and steady wins.

Half the population rejects whole grains (bread, pasta, rice, etc) because, on first try, it tastes like cardboard. Taste wins out over health. In my experience, it takes about 3 weeks of acclimation, then whole grains taste great. 3 week hump stands in way of significant public health improvement.
