Measurement of gastrointestinal pH profiles in normal ambulant human subjects
"Gastric pH was highly acidic (range 1.0 - 2.5) in all human subjects.
SUMMARY:
Gastrointestinal (GI) pH has been measured in 66 normal subjects using a pH sensitive radiotelemetry capsule passing freely through the gastrointestinal tract. Signals were recorded with a portable solid state receiver and recording system, enabling unconstrained measurements with normal ambulatory activities for up to 48 h during normal GI transit. Capsule position in the gut was monitored by surface location using a directional detector. Gastric pH was highly acidic (range 10-2.5) in all subjects. The mean pH in the proximal small intestine was 6.6 (0.5) for the first hour of intestinal recording. By comparison the mean pH in the terminal ileum was 7.5 (0.4) (p<0001). In all subjects there was a sharp fall in pH to a mean of6.4 (04) (p<0.001) as the capsule passed into the caecum. Values are means (SD). pH then rose progressively from the right to the left colon with a final mean value of 7.0 (0.7) (p<0

The Steak Lover's Diet
Gray Cloud was more than 100 years old and had never been sick. University scientists lived with him for several months and learned he mostly ate meat.
Gray Cloud, an old and wrinkled Indian, sat before the fire, drawing a geometric design with a stick in the dirt before him. Beside him, trying to double their long legs into comfortable positions, sat several visitors from the physiology department of a western university. Gray Cloud was more than 100 years old and had never been sick. No member of his family had ever been sick. Members of his tribe were sick so seldom that the fine new government hospital on the reservation stood unused, and the eager young government doctors fumed at the lack of business.
The visitors were there to discover what was responsible for Gray Cloud's longevity, and what conditions had made the tribe so unnaturally healthy. The college investigators lived with the tribe for several months. They learned how the Indians lived, and, more importantly for their study, what they ate. That's where the surprise came in: what they ate was meat. Cooked meat, raw meat, fresh meat, stale meat, sometimes decaying meat, but always meat. So the investigators returned to their laboratories to make extensive studies of the effects of a meat and fat diet on the body - something the Indians already knew.
The Indian was a meat eater. He hunted for his food; he did not grow it. He lived in a cave; eventually, he wore a loin cloth and skins for clothing. Today we wear Valentino gowns and Ivy League suits, but our stomachs have changed very little.
This is what the researchers found and reported in my medical journal. And this is what I discovered for myself when I implemented their findings in my own diet. When I changed my diet to meat, I quickly lost the weight that would not come off, and stay off, any other way -- and I was able to eat as much meat as I wished. No more starving; no more malnutrition; no more personal energy crisis. I lost weight, satisfied my appetite, and felt better than I had in years -- all from using a dietary "secret" that was really thousands of years old.

Eat Fat, Get Thin!
Dr Groves publishes book about low carb / carnivore diets.
"Do you like the idea of bacon and eggs for breakfast? Would you enjoy a lunch of roast salmon and a satisfying dinner accompanied by wine?
The EAT FAT GET THIN diet will allow you to do just that: the emphasis being on what you eat rather than how many calories the food contains. The rules are simple: keep your carbohydrates to a minimum by cutting out bread, potatoes and cereals, leave out the sugar, eat only the good fats and concentrate on protein rich foods.
The beauty of the EAT FAT GET THIN diet is that you will never go hungry. EAT FAT GET THIN proves that the diet on which it is most difficult to lose weight is a low-fat high carbohydrate diet. In fact, a century of studies and medical trials has consistently demonstrated that for safe wight loss a high fat diet is best."

Palaeolithic and Mesolithic kill-butchering sites: the hard evidence
The upper paleolithic is characterized by advanced hunting of large animals with various weapons, and planning to maximize easy prey
Upper Palaeolithic and Mesolithic Hunting:
the archaeological record leaves us some direct evidence of man's hunting activities. At Meiendorf (Rust 1937) and Stellmoor (Rusf 1937), some bones of reindeer and birds still conserve weapon marks and a few pieces of silex have remained thrusted in mammalian bones; man kills reindeer with harpoons and sticks (fractured skulls), birds with bows and maybe slings. Three fractured skulls of red deer in Abri Pataud (Bouchud, 1975), and one bovid skull with a circular orifice in Saint Marcel (Allain, 1952) suggest the practice of the so called " co'up de merlin": man has delivered a blow similar to the one used today to butcher cattle. Probably the animal already immobilized (wounded or entrapped) was hit on the frontal with a big stone. At Kokorevo I (Siberia), a large scapula of bison is pierced by the upper end of a point made of bone (Boriskowksi, 1965). At High Furlong (Mesolithic), an elk was discovered with the marks of L7 wounds made by barbed points, of which two were found in the site, and by other arms. The animal had apparently been attacked at two distinct occasions: during the first one, hunters aimed at the legs to lame the animal (fig. 6), later hunters hit the thoracic region and the lungs to kill it. However the elk died in a little lake, perhaps imprisoned in the ice, and man had no access to the meat. The animal represents in fact a hunting loss (Hallam et a1.,1973).
Planning: very good. Many sites belong to Wpe e, were occupied periodically or seasonally and specialised in the capture of a particular game (e.g., horse, reindeeq, ibex). Game drive towards cliffs have been claimed and Solutre (Combier & Thevenot,1976) has long figured as an example, but the evidence is far from conclusive.
Scavenging: no doubt H. sapiens still killed or exploited animals in the occasional and opportunistic way of Lower Palaeolithic times. According to Lindner (Lindner,1941), hunters at Predmost utilised the carcasses of hundreds of mammoths that probably succumbed as a result of natural catastrophes, as food.
Food transport: selective transport of the most useful animal parts is claimed for many sites.
Specialised activities: sometimes the material is dislocated in distinct clusters that could reflect specialised activity areas as for example at Solutre (Combier & Thevenot, 1976). Site topography: some hunting sites were located in valleys enclosed by steep slopes as at Rascano (Gonziilez-Echegaray, 1979), Stellmoor (Rust, 1937), Meiendorf (Rust 1937), or at the foot of rocky cliffs at Solutr6 (Combier & Th6venot, 1,976).
4. Conclusions
Most of the Lower Palaeolithic sites analysed here belong to category a (butchering sites); other kind of concentrations are rare and difficult to ascertain. A number of hunting stations (category e) and a hunting stop (category f) form my sample for the age of Neanderthal man and related people. The Upper Palaeolithic is characterised by many hunting stations, while in Mesolithic times a hunting loss (category d ) was found as well as several sighting sites (category g). The foregoing distribution seems to reflect in a vague way an evolution from scavenging and haphazard opportunistic hunting to well organised, selective hunting activities. However, this reflection results no doubt in part from a priori assumptions concerning the evolution of hominid meat procurement often colouring the interpretations offered for the osseous "hard" data; these are frequently equivocal.

Neanderthal diet at Vindija and Neanderthal predation: The evidence from stable isotopes
The isotope evidence overwhelmingly points to the Neanderthals behaving as top-level carnivores, obtaining almost all of their dietary protein from animal sources
Archeological analysis of faunal remains and of lithic and bone tools has suggested that hunting of medium to large mammals was a major element of Neanderthal subsistence. Plant foods are almost invisible in the archeological record, and it is impossible to estimate accurately their dietary importance. However, stable isotope (13C and 15N) analysis of mammal bone collagen provides a direct measure of diet and has been applied to two Neanderthals and various faunal species from Vindija Cave, Croatia. The isotope evidence overwhelmingly points to the Neanderthals behaving as top-level carnivores, obtaining almost all of their dietary protein from animal sources. Earlier Neanderthals in France and Belgium have yielded similar results, and a pattern of European Neander- thal adaptation as carnivores is emerging. These data reinforce current taphonomic assessments of associated faunal elements and make it unlikely that the Neanderthals were acquiring animal protein principally through scavenging. Instead, these findings portray them as effective predators.
Stable Isotope Analyses.
Mammal bone collagen δ13C and δ15N values reflect the δ13C and δ15N values of dietary protein (14). They furnish a long-term record of diet, giving the average δ13C and δ15N values of all of the protein consumed over the last years of the measured individual's life. δ13C values can be used to discriminate between terrestrial and marine dietary protein in humans and other mammals (15, 16). In addition, because of the canopy effect, species that live in forest environments can have δ13C values that are more negative than species that live in open environments (17). δ15N values are, on average, 2–4‰ higher than the average δ15N value of the protein consumed (18). Therefore, δ15N values can be used to determine the trophic level of the protein consumed. By measuring the δ13C and δ15N values of various fauna in a paleo-ecosystem, it is possible to reconstruct the trophic level relationships within that ecosystem. Therefore, by comparing the δ13C and δ15N values of omnivores such as hominids with the values of herbivores and carnivores from the same ecosystem, it is possible to determine whether those omnivores were obtaining dietary protein from plant or animal sources.

FOCUS: Gough’s Cave and Sun Hole Cave Human Stable Isotope Values Indicate a High Animal Protein Diet in the British Upper Palaeolithic
We were testing the hypothesis that these humans had a mainly hunting economy, and therefore a diet high in animal protein. We found this to be the case, and by comparing the human δ15N values with those of contemporary fauna, we conclude that the protein sources in human diets at these sites came mainly from herbivores such as Bos sp. and Cervus elaphus
We undertook stable isotope analysis of Upper Palaeolithic humans and fauna from the sites of Gough's Cave and Sun Hole Cave, Somerset, U.K., for palaeodietary reconstruction. We were testing the hypothesis that these humans had a mainly hunting economy, and therefore a diet high in animal protein. We found this to be the case, and by comparing the human δ15N values with those of contemporary fauna, we conclude that the protein sources in human diets at these sites came mainly from herbivores such as Bos sp. and Cervus elaphus. There are a large number ofEquus sp. faunal remains from this site, but this species was not a significant food resource in the diets of these Upper Palaeolithic humans.
If the humans hunted and consumed mainly horse, then their 15N values should be c. 3–5‰ (Equus 15N value of 0·7‰+enrichment of 2–4‰). Instead, their 15N values make more sense if they lived mostly off Bos and Cervus elaphus (Bos and Cervus values of c. 3‰+enrichment of 2–4‰=the observed values c. 6–7‰). It is also possible that other species, including Rangifer tarandus, were consumed by these individuals. Rangifer tarandus has 15N values similar to Cervus elaphus (Richards, 1998), and has more positive 13C values, which may explain the observed slight enrichment in the human 13C values. A number of artefacts made from Rangifer tarandus have been found at Gough’s, but there is no other evidence that this species was being exploited for food

One report states that a trainer named Pythagoras recommended a meat diet to the Olympic athletes he trained.
A lack of animal-derived protein seems to have been rectified early in history, as there are two reports of the introduction of meat into the athletes’ diet. One report states that a trainer named Pythagoras recommended a meat diet to the athletes he trained. https://www.omicsonline.org/open-access/a-comparison-of-ancient-greek-and-roman-sports-diets-with-modern-day-practices-2473-6449-1000104.php?aid=69865
8 He [Pythagoras] is said to have been the first to train athletes on a meat diet. The first athlete he did this with was Eurymenes. Formerly they had trained on dried figs, moist cheese, and wheat. Some say that it was a trainer named Pythagoras and not the philosopher who was responsible for this innovative diet. For our Pythagoras prohibited killing, not to mention eating, life which possessed souls like our own.

Sport and Recreation
To all appearances medical knowledge in general and nutrition in particular was widespread in Pythagorean circles in Southern Italy, especially in Kroton. Burkert has pointed out that the fmaous doctor Alcmaeon came from the Pythagorean center of Kroton. From the akousmata (secret doctrines), which doubtless contain old religious traditions, we learn that the Pythagoreans were not originally strict vegetarians; the consumption of meat was permitted, with the exception of lamb and the meat of draft oxen. Burkert considers there is some likelihood that Pythagoras introduced a meat diet for athletes. He believes this tradition arose when Pythagorean vegetarianism had not yet been completely developed. In later times, when vegetarianism had prevailed, a second tradition has possibly been invented, in which it was not Pythagoras, the philosopher from Samos and Kroton, but a homonymous person who wrot the great 'trainer's recipe book'.
57: There are similar issues regarding the transmission in later sources of Pythagoras advising the successful heavy athlete Eurymenes of Samos to use a special meat-based diet instead of the dried figs and cheese he had previously been eating.

A Comparison of Ancient Greek and Roman Sports Diets with Modern Day Practices
Dromeus, a long-distance runner, is said to have first thought of eating meat for training instead of just cheese and won multiple victories.
The second report is that of Pausanias, who writes of Dromeus, a long-distance runner from Stymphalos [23].
“...he won two victories in the dolichos at Olympia, the same number in the Pythian Games, three at the Isthmian and five at the Nemean. He is said to have first thought of eating meat (as part of his training diet). Until then the food for athletes was cheese fresh out of the basket.”
Clearly, if his success is anything to go by, then Dromeus had really found a winner’s diet. There are also reports of athletes eating meat from oxen, bulls, goats and deer, a very” red-meat” diet which is a rich form of protein. Moreover, with meat as a part of their diet, the performance of competing athletes would most certainly have improved noticeably.

Dromeus, Long-Distance Runner
There was a man from Stymphalos, named Dromeus, whose record as a long-distance runner was exceptional: he won two victories in the dolichos at Olympia, the same number in the Pythian Games, three at the Isthmian and five at the Nemean. He is said to have first thought of eating meat (as part of his training diet). Until then the food for athletes was cheese fresh out of the basket.
