Prolonged starvation changes energy metabolism; therefore, the metabolic response to starvation is divided into three phases according to changes in glucose, lipid and protein utilisation. B-group vitamins are involved in energy metabolism via metabolism of carbohydrates, fatty acids and amino acids. To determine how changes in energy metabolism alter B-group vitamin concentrations during starvation, we measured the concentration of eight kinds of B-group vitamins daily in rat blood, urine and…

Tissue vitamin concentrations are maintained constant by changing the urinary excretion rate of vitamins in rats’ restricted food intake
TLDR
The results show that the tissue concentrations of B-group vitamins were kept constant by changing the urinary elimination rates of vitamins under various levels of food restriction.
Excess Vitamin Intake before Starvation does not Affect Body Mass, Organ Mass, or Blood Variables but Affects Urinary Excretion of Riboflavin in Starving Rats
TLDR
Excess vitamin intake before starvation does not affect body mass, organ mass, or blood variables but does affect the urinary excretion of riboflavin in starving rats, and urinary rib oflavin excretion showed a different pattern.
Urinary protein changes in a rat starvation model
TLDR
The effect of starvation on the body may possibly reflect urinary protein changes, and a short duration of starvation can cause the acceleration of protein metabolism and increases in nitrogen excretion, leucine flux and oxidation.
A Suitable Diet for Recovery from Starvation Is a High-Fat Diet, but Not a High-Protein Diet, in Rats.
TLDR
It is hypothesized that a HFD is most suitable for quickly reversing the influence of starvation, and the recovery of body weight after starvation was excellent in the HFD group.
Relationship Between Urinary Concentrations of Nine Water-soluble Vitamins and their Vitamin Intakes in Japanese Adult Males
TLDR
Urinary excretion levels for seven of the nine water-soluble vitamin levels, excluding vitamin B12 and folate, increased linearly and sharply in a dose-dependent manner, suggesting that measuring urinary water- soluble vitamins can be good nutritional markers for assessing vitamin intakes in humans.
Intake and Urinary Amounts of Biotin in Japanese Elementary School Children, College Students, and Elderly Persons
TLDR
This work examined urinary excretion and the intake of biotin in a Japanese sample population of 60 boys and 36 girls, 37 male and 135 female college students, and 35 female elderly persons living freely for maintaining good health.
The niacin required for optimum growth can be synthesized from L-tryptophan in growing mice lacking tryptophan-2,3-dioxygenase.
TLDR
Findings show that the kynurenine formed in extrahepatic tissues by IDO and subsequent enzymes can be metabolized up to 3-HA, but not into QA.
Metabolomics analysis for hydroxy-L-proline-induced calcium oxalate nephrolithiasis in rats based on ultra-high performance liquid chromatography quadrupole time-of-flight mass spectrometry
TLDR
It is suggested that a number of metabolic pathways are dysfunctional in the HLP induced crystal kidney injury, and further studies on those pathways are warranted to better understand the metabolic mechanism of CaOx nephrolithiasis.
Urinary Excretion of 2-Oxo Acids Is Greater in Rats with Streptozotocin-Induced Diabetes.

TLDR
Findings indicate that energy production in the body is suppressed under diabetic conditions, and greater urinary excretion of unused 2-oxo acids thus implies an impairment in energy production.
Atlantic Grey Seal Milk Shows Continuous Changes in Key Metabolites and Indicators of Metabolic Transition in Pups From Birth to Weaning
Mothers of the Atlantic grey seal, Halichoerus grypus, lactate for about 20 days, during which they do not feed and may have no access to water. Following weaning, they depart to sea leaving their…

Effect of fasting on the urinary excretion of water-soluble vitamins in humans and rats.
TLDR
Water-soluble vitamins were released from the liver, and supplied to the peripheral tissues to maintain vitamin nutrition, and the effect of fasting should be taken into consideration for subjects showing low urinary thiamin and high urinary riboflavin.
Starvation in the rat. II. Effect of age and obesity on protein sparing and fuel metabolism.
TLDR
Findings support the contention that the conservation of protein during prolonged starvation requires the continued availability of lipid fuels and the role of insulin and thyroid hormone in modulating these adaptations is unclear.
Mild pantothenate deficiency in rats elevates serum triglyceride and free fatty acid levels.
TLDR
Mild pantothenate deficiency appears to have observable in vivo effects on triglyceride metabolism before severe deficiency causes significant weight loss, and serum triglyceride and free fatty acid levels were significantly elevated in pantothene-deficient groups.
Effect of short-term and long-term fasting on transcriptional regulation of metabolic genes in rat tissues.

Uric acid and urea in relation to protein catabolism in long-term fasting geese
TLDR
Plasma uric acid and urea concentrations and their excretion as a proportion of total nitrogen excretion were studied in relation to daily change in body mass per unit body mass, dm/mdt to determine whether birds which naturally fast in connection with specific activities have entered into the situation where proteins are no longer spared.
Physiology and biochemistry of long-term fasting in birds
TLDR
The metabolic response of penguins and domestic geese to fasting has been studied in detail and it is shown that large birds, in contrast to small species, do not become torpid when they are fasting.
Urinary excretion of vitamin B1, B2, B6, niacin, pantothenic acid, folate, and vitamin C correlates with dietary intakes of free-living elderly, female Japanese.
Increased conversion ratio of tryptophan to niacin in severe food restriction.
TLDR
The conversion ratio in the 1/2, 1/4, or starving group increased at day 1 of the experiment, but returned to the original value from day 2, and only in the starving group did the conversion ratio extremely increase from day 6 to day 9, being about 5-times higher than that of the originalvalue on day 9.
The biochemistry of fatty liver and kidney syndrome. Biotin-mediated restoration of hepatic gluconeogenesis in vitro and its relationship to pyruvate carboxylase activity.
TLDR
It is concluded that the fatty liver and kidney syndrome involves the lack of available biotin in the liver rather than suppression of apocarboxylase synthesis, and restoration of gluconeogenesis did not occur if biotin was excluded from the nutrient medium, nor was it prevented by protein-synthesis inhibitors.
