This is a telling graphic that explains a bunch, and deserves it’s own discussion. Basically – the less carbohydrates an individual has, the more predictable the outcome.

Ketone bodies (KB), acetoacetate and β-hydroxybutyrate, were considered harmful metabolic by-products when discovered in the mid-nineteenth century in urine of patients with diabetic ketoacidosis. It took physicians many years to realize KB are normal metabolites synthesized by the liver and exported into the systemic circulation to serve as an energy source for most extrahepatic tissues. […]
The “carbs make you fat” meme really took off since Taubes and it inspired a gazillion cringe-worthy infographics.

Current carbohydrate recommendations are based on
1) preventing ketosis
2) providing glucose beyond minimal needs
However, ketosis is not harmful, and the need to provide glucose above minimal needs has never been demonstrated.
There is no RDA for carbohydrates, probably because the human body can adapt to a carbohydrate-free diet and manufacture the glucose it needs.
You’ll be reassured to know that you don’t have to eat carbohydrates to live. It’s not an essential nutrient. It’s one of the first things we learn in nutrition is what does the body not make and what you HAVE to eat. You won’t find carbohydrate on this list.

Within days of starting carbohydrate restriction, most people begin excreting ketones in their urine.
Strips that test for ketones in the urine detect the presence of acetoacetate.
After a few weeks, muscle cells take up acetoacetate and reduce it to beta-hydroxybutyrate.
Thus urine ketone testing is a rather uncertain if not undependable way of monitoring ketosis.

It appears, from most literature studied, that a very low carbohydrate diet is, if anything, protective against muscle protein catabolism during energy restriction, provided that it contains adequate amounts of protein.
It is concluded that the ketogenic diet may have antidepressant properties.
Severely obese subjects with a high prevalence of diabetes or the metabolic syndrome lost more weight during six months on a carbohydrate-restricted diet than on a calorie- and fat-restricted diet, with a relative improvement in insulin sensitivity and triglyceride levels, even after adjustment for the amount of weight lost.
Serum triglycerides (fat levels in blood) were measured fasted and after a high fat meal, then subjects were put on a ketogenic diet and fasting trigs tested throughout for eight weeks.
After the keto intervention both the fasting and post-prandial response to the high-fat meal showed the serum triglycerides had decreased by about half, demonstrating a profound improvement in metabolizing dietary fat.
The commonly-held belief that the best diet for prevention of coronary heart disease is a low saturated fat, low cholesterol diet is not supported by the available evidence from clinical trials. In primary prevention, such diets do not reduce the risk of myocardial infarction or coronary or all-cause mortality.
Similarly, diets focused exclusively on reduction of saturated fats and cholesterol are relatively ineffective for secondary prevention and should be abandoned.
Subjects were fed either a high carbohydrate, high fat, or high protein meal.
The carbohydrate and protein meals increased insulin levels significantly, however not with the fat meal.
The protein meal was also followed by an increase in glucagon, whereas the carbohydrate meal reduced it significantly.
Rats fed a low protein (10%) diet which is high in fat (90%) retained normal brain glucose utilisation even in a low blood glucose scenario.
However in a low protein and low fat scenario where the fat is swapped out for carbohydrates (78%) it results in the rats depressed ability to use glucose in the central nervous system, to a degree seen in brain disorder levels.
Two young girls with brain cancer were put on a ketogenic diet, within a week a decrease of 22% glucose uptake was noted at the sites of the tumor.
One subject continued the ketogenic diet for an additional year, remaining free of disease progression.
Cholesterol fell significantly during the first months of significant weight loss, after which it rose above baseline as weight loss continued. With weight maintenance, cholesterol fell again and stabilised.
We conclude major weight loss was associated with a late rise in serum cholesterol, possibly from mobilization of adipose cholesterol stores, which resolved when weight loss ceased.
Adult rats were fed diets of either high carb or high fat, final body weight was lower in rats fed the high fat diet, and also had the highest protein gain.
An attempt has been made to reverse cachexia (muscle wasting/fatigue/etc) by depriving tumours of energy by feeding a ketogenic regime.
Mice were implanted with a form of colon cancer which produces extensive weight loss without a reduction in food intake.
When mice were fed on diets in which up to 80% of the energy was supplied as medium chain triglycerides (MCT) weight loss was reduced in proportion to the fat content of the diet, and the tumour contributed less to the final body weight.
To study the metabolic effects of ketosis without weight loss, nine lean men were fed a balanced diet for one week followed by four weeks of a ketogenic diet.
- Weight and whole-body potassium did not vary significantly during the five-week study.
- Nitrogen balance was regained after one week on keto.
- Fasting blood glucose remained slightly lower during keto, glucose oxidation rate fell significantly.
- Serum cholesterol levels rose, while triglycerides fell.
- No disturbance of liver or kidney function was noted at the end.
During a ketogenic regimen concentrations of fat derived substrates rise significantly and glucose levels decrease, hormonal patterns switch towards a catabolic mode with a fall in insulin levels and a rise in glucagon concentration, levels of gluconeogenic amino acids are reduced while those of the branched chain amino acids increase.
These changes also reproduce those observed after a few days of total fasting, suggesting it is the carbohydrate restriction itself which is responsible.
Ketone bodies accumulate in the plasma in conditions of fasting and uncontrolled diabetes. The initiating event is a change in the molar ratio of glucagon:insulin. Insulin deficiency triggers the lipolytic process in adipose tissue with the result that free fatty acids pass into the plasma for uptake by liver and other tissues. Glucagon appears to […]
Weight loss observed during the carbohydrate-restricted diets was significantly greater than during the high-carbohydrate diet.
Electrolyte excretion during the first 7-14 days was significantly greater on the low-carbohydrate diet, whereas after 28 days it was not significantly different from the high-carbohydrate diet.
To study the capacity for moderate endurance exercise and change in metabolic fuel utilization during adaptation to a ketogenic diet, six moderately obese, untrained subjects were fed a eucaloric, balanced diet (base line) for 2 wk, followed by 6 wk of a protein-supplemented fast (PSF), which provided 1.2 g of protein/kg ideal body wt, supplemented […]
