I have been maintaining projections on omnitech.net/blog and fb.com/xaminmo .
Basically, it is time to hide from society right now. There are a lot of people still spreading it because it is their right to be free. If you get it now, there will be no resources to help you if you get very sick.
Projections may change by Wednesday, since that is 12 days after the national emergency was declared. If we cut our spread in half, then we get almost an extra week of respite.
Except, I know groups of people who were congregating for public meals as recently as Wednesday, and group exercise just Friday. 6 feet at 14mph is not enough. I don’t have the ability to get people to trust me. Either they see, or they don’t. Plenty actively disbelieve. It’s core to their being to believe exactly opposite of me.
We got complacent, because we’re “not like Italy. Look, they are older, and we were infected sooner. We’re so much better, and our death rate is lower.”
Italy started at +25% per day, and brought it down to +12% per day.
The US started at +5-10%, but for weeks has been spreading at +35% per day. Texas, my state, has to do it bigger. We’re spreading at +47%.
So, April 2, Texas ICU reserve capacity is overrun. A week later, all Texas hospital reserve capacity is overrun. I don’t know where in there we run out of trained medical professionals and supplies to treat safely.
If we did a great job when the pandemic was declared, we get 4-6 more days. A week prior, it will look like a normal day, a little busy, and probably still no toilet paper.
I wish it were not so, but the window of opportunity to change this course is almost closed, and we seem to be accelerating towards it, not slowing.
A tsunami is coming, and we have not even felt the tremor yet.
US death rate is low and falling. It is so far lower than everywhere else, I strongly suspect that the dead are not being tested for the virus, and only if they were already tested would they be considered a SARS-2 death.
In reality, the death rate we’re looking at is per infected person, and that is a false-low. Plenty of infected people have time yet to die. You have to plot it based on deaths per recovered person to get a true value. Since we are not done with the outbreak, and the US is still pretty early into the big numbers, that mortality rate is artificially high. China is 4.0 for mortality per all, and 4.37 for mortality per recovered. The US is 1.28% and 62.4% respectively.
It is more likely that the US infection rate is so high that not enough people have had time to die. I think in the next week, we’ll begin to see larger numbers of US CV19 patients dying. Also note that the US infection rates have dramatically risen the last 2 days. This may reflect an improvement in testing ability and reporting.
The alternative is that we’re accelerating due to people disbelieving the quarantine. I still see that locally in the Flower Mound area. Mid-week, people were still gathering for group meals, and group outdoor exercise. 6 foot spacing is not sufficient when you’re downwind from someone, such as when you are moving 10-15mph in a straight line.
Where Cases Deaths Recovered Mort/A Mort/R World 272,167 11,299 87,403 4.15% 11.45% China 81,250 3,253 71,266 4.00% 4.37% Non-China 190,917 8,046 16,137 4.21% 33.27% Italy 47,021 4,032 4,440 8.57% 47.59% US 19,101 244 147 1.28% 62.40% Texas 394 1 0 0.25% 100.00% France 12,632 450 12 3.56% 97.40% United Kingdom 4,014 178 67 4.43% 72.65%
Mortality rates all vs recovered are 3.56/97.4 for France, and 4.43/72.65 for UK. More in line with everyone else. Again, too early for the mortality per recovered person to make much sense.
Current 7-day average daily change rates for deaths in US, FR, and UK are 145.75%, 174.69%, and 160.33% respectively.
Daily Change Avg 7 Days World 113.75% China 100.18% Non-China 121.04% Italy 116.38% US 145.75% Texas 133.33% France 174.69% United Kingdom 160.33%
Current 7-day average daily change rates for confirmed cases in US, FR and UK are 157.69%, 118.24%, and 125.30%. In other words, the US is spreading the infection at double the rate of the UK, and three times France.
Daily Change Avg 7 Days World 112.54% China 100.09% Non-China 119.46% Italy 114.74% US 157.69% Texas 150.91% France 118.24% United Kingdom 125.30%
That is in line with predictions that our death rates look lower because we’re spreading faster, and people have not had time to die yet.
US +6000 each of 2 days. It is throwing off the projections. Is this the new rate, or catching up on deferred testing/reporting?

I expect the US death count to jump soon, but that’s only because I do not know why the death rate is so low in the US. (Nationalistic zeal,. eg we are better than them because…, is probably not the cause.)

The new US numbers are questionable as stated above.
This is a great write-up and is very much in line with what PubMed abstracts have to say.
This is a great write-up and is very much in line with what PubMed abstracts have to say.
This write-up is in response to some claims that humans were not built to eat meat.
Human biology is built for endurance hunting. We are not structured to eat meat with every meal, but some of our essential vitamins are only naturally available from meat.
Plant carbohydrate is the only fuel which causes multiple metabolic dysfunctions when consumed in excess of immediate needs. The US shift from fat to carbs in 1977 for bulk energy recommendation coincides with the sharp beginning of the US obesity epidemic.
Grains, pulses, roots, etc are not naturally a primary food source. They require substantial technology to prepare. The vegetable foods we can eat are not available year round without major technological advancements.
Some of our survival does absolutely rely on plants as well, including non-digestible plant matter, and other vitamins.
It’s not that we “can” eat both. It’s that we truly are adapted to require eating both. Technology allows us to get around this requirement, but it is not in any way “natural”.
We’re also not adapted for having food instantly available all the time, and we are not adapted to using carbohydrate as a primary source of energy.
Long rambly supporting info:
We, and our ancestors back to previous species, have a biology designed to follow prey around to the point of the prey’s exhaustion. While many animals can move faster than us in the short term, very few can travel as far as we can in a few hours, or even in a day, without becoming incapacitated by fatigue. At that point, we simply walk up to the prey and run it through with a stick.
We are upright, which gives us a reduced thermal load from spending a long time moving in the sun.
It also supports both wooded foraging and coastal hunting.
Compared to our ancestors, we devolved upper body strength and evolved lower body strength to support hunting, at the expense of being able to harvest and climb trees to the same level as other primates. We lost our opposable big toes, and our knees angled towards the middle a bit. This is an adaptation to extended running or walking, and use of tools instead of brute strength.
Our digestive tract is designed for meat occasionally, but not constantly. The gallbladder stores and concentrates bile, and our bile is hydrophobic (eg, is used to digest fats).
Some of our vitamins only come from meat, or bioengineered foods. The most critical is Vitamin B12.
The canine argument is non-scientific. Canines, and pointed teeth, and claws, are for killing rapidly, both for territorial purposes and for hunting. Many species of primates have huge canines, even the ones that don’t eat much meat.
Humans don’t kill with our teeth and claws. Not a factor for what we should eat. Whales don’t have canines either, and they eat tons of small shrimp and fish every year.
True herbivore teeth generally continue to grow throughout life, because it’s extra hard on teeth. We have two sets of teeth, one to fit our small head, and one set to fit our grown up heads. Birth size and brain growth come into play there. We live twice as long as we would in the wild, and we’re still dealing with people who, despite dental precautions, still have to have dental appliances.
Our front teeth have fairly sharp corners, and a chisel edge, designed for biting out big chunks at a time. Basically, once we get food, we need to be able to eat a bunch of it fast, because more dangerous predators would come along soon.
Note that what society considers meat is very limited. In the wild, primates would eat birds, lizards, insects, crustaceans, worms, and anything else available. Some primates eat other primate species on a monthly basis.
Also compare our digestive tracts past the teeth. Our stomach is designed to help break down meat, and liberate protein. Our duodenum is designed to begin the breakdown of fats. Our jejunum is designed to absorb carbs, fats, and proteins that have been liberated above. Our ileum is designed to absorb trace nutrients, excess bile, vitamins, and whatever wasn’t absorbed above. Our colons are designed for residual fermentation and moisture absorption.
Our colons are half the size of our more vegetarian cousins among primates. We also have a very small appendix. These are related to having a lower capacity to break down cellulose. In other words, we can eat some vegetation, but not the same variety as some other species.
Our stomachs are elastic, and can hold quite a lot of food. Human gastric juice is specifically designed to break down proteins.
When food is low in animal protein, food passes fairly quickly through the stomach. When it’s very meaty, it hangs out in the stomach for multiple hours.
Info about gastric emptying rates:
* local copy at http://omnitech.net/health/2018/06/06/digestion-time-of-various-foods/
* Sorry this last one is not better quality. I have not been able to find research, nor older references.
This delay is so that we can absorb all of it, not because we’re having a problem. Problem foods either come up, or pass through rapidly.
Herbivores, such as cattle, use extended duration fermentation to break down plant matter.
Basically, our structure is specifically adapted to handle different types and amounts of foods, depending on whatever is available at the time.
A major exception is that we’re structured to not eat large amounts of carbohydrates except when we are recovering from, or in the middle of endurance exercise. We’re better at it than our distant ancestors, because we’ve been doing agriculture for a LONG time, way longer than written language.
If we have been out hunting all day, then eating the equivalent of 10 refined peaches in 5 minutes is not so bad. It goes into the muscles and the liver to replenish glycogen, repair damage, and keep feeding ATP systemwide.
When we are recovered, this is not the case.
Our insulin has a half-life of about 10 minutes naturally, Natural insulin levels oscillate by a factor of 8 over 3-6 minute periods. When our livers and muscles are replete with glycogen (locally stored carbohydrate), those tissues refuse to absorb more glucose.
In response, blood glucose levels go up, and the body releases even more insulin. The loop happens until our fat cells kick into overdrive, and our livers kick into overdrive, and all of the glucose gets stored as fat.
During this process, our muscle cells down-regulate their sensitivity to insulin, because obviously, something is wrong. Muscles are already full, so why are you trying to feed them? Literally, GLUT4 receptor production rate is related to the energy needs of the cell. If the needs are low, then the levels can be reduced enough to induce insulin resistance.
Also, insulin is transported into a cell along with the transport protein. Endocytosis of the GLUT4 receptor is faster than regeneration and exocytosis.

Muscle cells have secondary functions to absorb glucose when needed anyway, so it’s just a courtesy that they listen for insulin at all.
Along the same lines, the pancreas down-regulates the number of islet (beta) cells, because obviously, such high levels of insulin must mean we have too many cells. https://www.ncbi.nlm.nih.gov/pubmed/15655713
Unfortunately, in its panic, the liver has to pack it into very low density lipoprotein myceles (VLDL), which is particularly difficult for our body to deal with. This gets stuffed into the walls of our arteries just to keep it from killing us on the spot. This leads to necrosis, clots, hardened arteries, etc.
None of this cascade of metabolic hormone dysfunction happens from eating excess meat, though excess of any food can lead to obesity and long-term insulin resistance. Protein takes longer to convert to glucose, but does have a nitrogen load on the kidneys. There are limits to how much can be acquired “in the wild”, and this tends to be much better self-regulated due to the longer gastric clearance times.
* more sources needed here, but I’m tired.
Eating high amounts of animal fat or cholesterol also does not cause a lipid problem for the blood. Dietary fats are packaged as High Density Lipoprotein (HDL) and carried to the liver for further processing, or to fat cells for storage. HDL has the benefit of also scavenging free fatty acids out of the blood, and off of the walls of blood vessels.
80% of the body’s cholesterol is produced by the liver, and excess is excreted by being bound in non-digested plant matter in the intestines.
Note that the epidemic of obesity in the US aligns closely with the low-fat claims. The recommendation for low-fat diets coincides with higher carbohydrate consumption (how else do you get energy?). This shift happened in 1977. You can see this coincides with a sharp uptick in obesity rates here:
In summary, we’re supposed to eat alternating meat and plant meals, but not so much in the way of carbohydrates. When we do eat carbohydrates, it would be perhaps one or two small pieces of fruit during a hunt, or as a special treat during the week that the small fruits were ripening on the tree, but not demolished by birds, or perhaps a handful of grass seeds or beans in passing.
A nice reference of all of the pieces of the digestive system:
- Further discussion could be had on the health, social, and environmental implications of using technology to bypass these physiological limitations.
I ponder macro-nutrition needs a whole bunch. Here’s what I have handy, though my technical references are scattered and omitted.
There’s always a need for roughage, vitamins, and minerals, which come from foods with very low calories/kilojoules. Aside from that, the three main macros have specific needs.
A body needs 125 grams of carbs for your brain/nerves; just under 1 gram of protein per kilo of lean body mass to maintain tissues/muscles; and around 30g of fat for cellular and neurological structures. This is usually around 1200 kcal per day, but varies by person 10-20 percent.
Anything else you eat is either poop, or gets converted to sugar. Sugar is burned if it’s needed immediately for exercise (growing, standing, walking, cardio, whatever, anything other than sleeping). Any sugar that is not immediately needed is stored in muscles as glycogen, up to around 4% of your muscle mass. All sugar past that is turned into fat and stored in our fat cells.
This is where “whole grains” comes into play. If it’s not ground up, it takes longer to break it down. However, if you take grains, and mill them into a powder, IT IS NOT WHOLE GRAINS. Just because there is fiber in the food does not mean it’s slow to absorb. The less processed the food, the longer time period over which it trickles energy into your body. If it’s super processed, it all absorbs very quickly, and your body may have trouble figuring out what to do with it unless you’re depleted already.
This is also where some insulin resistance comes from, and why diabetics have normal sugar metabolism in their muscles during exercise, even if they are short on insulin, or are resistant to it. Resistance is GLUT4 which causes glucose receptors to move to the cell membrane, but exercise does the same thing – muscle is hungry, it asks for more. Muscle is not hungry, it asks for less, even if you try to overfeed it. Where would it put this excess sugar? It can only store so much.
During exercise, your fat cells can liberate about 90% of your weight in pounds as usable calories per hour. For me, it’s about 260 calories. The gap is made up from glycogen in the muscles, which is good for just about 90 minutes. If you exercise hard, and stop at 60, and rest for 30, those 30 mins still use up that glycogen for delayed processes, cleanup, etc.
Eating carbs cannot provide as much energy as glycogen, but it’s the next best thing. Also, if you’re fasting, your glycogen reserves get burned up pretty quickly. Glycogen is 3:1 water to sugar, so this is why the first week of dieting is so awesome. No, that’s not fat. It’s muscle energy.
Any energy deficiency not covered by food will be covered by muscle damage. About the same number of calories can be broken down out of injured muscle cells. For me, this is a total of muscle and fat sourced calories of about 520 calories per hour. If I exercise for 3 hours with no food, then my power output drops to 130 watts, which is about 520 calories per hour.
The best option to limit muscle damage, limit recovery time, and optimize exercise benefits when going for more than your glycoge, is to eat as much every hour as you burn, minus the calories that can come from fat. Staying carb focussed can give more energy, and can be easier to absorb, though for some people, this slows the breakdown of body fat.
Staying fat focussed keeps the fat burn mechanisms running, but it takes twice as much oxygen, which means you’re hear-rate limited. It’s less about muscle conditioning then, and more about cardiovascular improvement.
Staying protein focussed is tougher on the kidneys. The aminos have to be converted for use as fuel, and that’s a lot of extra ammonia to pee out. That can be an issue when dehydration might already be at play.
I keep a notepad on my phone to track what I did and what’s next. End of workout, I add the updated list to MyFitnessPal in the exercise notes. This keeps me from twiddling my thumbs during rests.
#### Warmup is cardio:
* About 10 mins or 200 calories warmup on the recumbent bike. I’ll start at about 50%, and crank it up to 100% a couple of times. I try to vary my RPM, but tend to hang out around 70. I have long legs, so momentum is a factor. I make sure I clear 160bpm, but I never get to max HR. Sometimes I try to draw pictures with the hill profile.
#### Safety warmup for exercises I’m not sure about:
* 10-20 reps at 50-60% just to make sure everything moves right, especially for heavier weight exercises.
#### I usually go for strength
* Target is 2-4 sets of 6-10 reps per exercise.
* If I make it to 16 reps, I bump up the weight on the next set.
* Sometimes I’ll do 8 reps, then drop 40% and do another 8.
* If anything pinches or doesn’t feel right, I’ll back off the weight.
* Not so worried about cardio since I average 75 miles per week on a road bike.
#### I do circuits for time efficiency:
* Whole Body Days: alternate upper/lower, front/back, with 30 second rests between circuits.
* Upper OR Lower Only: I’ll do 2-3 exercises with a 60-90 second rests.
* I average almost one working set for every 2 minutes. That includes the set, equipment setup, walking between machines, updating my notes, and any rest/cooldown time. That excludes the warmup time at the start. (eg, a 2 hour workout has 20 mins of warmup, and 40-45 working sets. A 1-hour workout will have 10 mins warmup, and 18-24 sets.)
#### With a workout buddy:
We could alternate on the same machine with 60-90 second rests. This is less overall workouts, but more social. We could also do the circuits, and just be one machine off from each other. Less social, but more efficient.
#### Workout Duration:
I prefer a longer, whole body workout every 4 days. I get better results, and less wasted time. My goal is to grow muscle mass, and I’m missing the sprinter gene, so recovery time is usually 3-5 days instead of 2-3 days for most people.
If I have only 1 hour, it’s best if I stick to only upper or only lower, because exercises always pull in a other muscles a little. I don’t feel I get quite as good of a workout this way.
#### Upper Body Exercises:
* Freeweight bench row (Low-Back sparing vs seated)
* Chest Press (like a bench press)
* Lat Pulldowns
* Seated dips (because I’m too heavy to do real dips yet)
* Chest fly & rear deltoid fly (same machine, diff settings)
* Biceps curls (cable or dumbell)
* Triceps extension (Slow to improve)
* Sometimes I do a shoulder press or a vertical row, but those are not so great on my shoulder sockets.
* Lateral dumbell arm raises.
#### Lower Body Exercises
* Freeweight seated calf extension (Soleus Muscle)
* Rotary Calf Extension (Gastroc Muscle)
* Inner/Outer thigh (adductor/abductor)
* Leg Curls (Hamstrings)
* Leg Extension (outer and inner quads, nearer the knee)
* Leg Press (because it doesn’t load my low-spine like squats & deadlifts do.)
###### Back Pain avoidance (Chronic and Acute)
* Nothing with a torso twist (wood choppers, obliques) – always causes days of increased pain.
* No abdominal crunches – Still hurting from 2 weeks ago when I let my form get sloppy.
* No back extensions – Same as with crunches, though a 45 degree bodyweight back extension bench would be fine if I could find that at my gym.
* Backed off of seated rows, just to be safe. I’ve moved to bench rows, though bent-over single-arm dumbell rows are okay too (off-arm is on the bench, so no low-back load).
* I should be doing planks and leg lifts at home, but I keep forgetting. This gets core without abusing low-spine.
* I should do more stretching on non-workout days, but I keep forgetting. This helps keep from putting too much strain on low-back when moving around.
#### Preferred Machines
I like the Hoist machines my Gym has best, but I’ve maxed out the leg press. Not sure I want to use the freeweight leg press without a big spotter. I like most of the Precor machines, and use them for things missing from the Hoist line-up. Last are the Life Fitness for a couple things, but they use bigger weight stacks for the same effort, and just seem to be on a different scale from all of the others.
This is what SEEMS to make the most sense for me. No *way* is easy, but this seems the least hard.
* Defer first meal until actually hungry (9:30a-12:30p for me)
* Keep each meal before 3:30pm around 12% of my daily intake.
* Eat before I get ravenous (around every 2 hours).
* Try to keep a reserve of about 25% of my calories for the evening.
* Don’t be TOO aggressive (20% deficit is okay, but 40% is not).
* Keep extra servings away from my plate/bowl.
* Split up snack/mini-meals when I’m not hungry.
* Stay busy (yay computer!)
* You have to exercise, because your body will reduce your BMR to keep from losing fat reserves.
* Hungries are worse the day AFTER exercise, so save your calories for tomorrow.
* Lots of broths, leaves, fresh veggies to add bulk, and fill in when I’m STILL HUNGRY!
* Make sure I get the food groups and vitamins daily / weekly rather than every meal.
* UMAMI: Your tongue creates Peptide YY it detects meat, glutamate, etc. Reduces hunger by 30% in the lab.
* VITAMIN A: Hunger hormones are produced by fat cells. Empty fat cells do not get recycled without Vitamin A.
* VITAMIN D: Vitamin D is blocked by Vitamin A, and is deficient for many indorsy people.
* CALCIUM: Requires Vitamin D to be absorbed. Prevents brittle bones.
Some days will be better than others. Don’t give up. Keep tinkering.
