This study was designed to investigate the long-term metabolic adaptations and health effects of a low-carbohydrate, high-fat/protein diet in mice. One-month-old male ICR mice were fed a control, conventional high-carbohydrate diet (n=21) or an experimental low-carbohydrate, high-fat, high-protein diet (n=20). One pair of mice per group was euthanized at two-week intervals for five months for tissue analysis. Basic metabolic data, body and tissue weights, blood and plasma metabolite and lipid profiles, liver glycogen and protein content, and liver serine dehydratase and glucose-6-phosphate dehydrogenase activities were analyzed. The low-carbohydrate group gained significantly more weight (p<0.005 after 4 weeks) than the normally growing control group. Although ketosis was initially stimulated in the low-carbohydrate group, enzyme and tissue analysis suggest that gluconeogenic activity was sufficient to alleviate the effects of severe dietary carbohydrate restriction and allow for glucose metabolism close to that demonstrated in the control group.

This study aims to analyze the effect of a low-carbohydrate high-protein diet to increase the level of antioxidant, decrease inflammation and improve performance of athlete. The research was carried out by experimental research methods, within the design of "Randomized Control Group Pretest Posttest Design".A sample was taken from 20 people who met the inclusion and exclusion criteria from 30 teenage athletes in PASI East Java sprints. The Data were collected by measuring the sprint results by finish photo camera and laboratory examinations to determine the levels of antioxidants (SOD) and the inflammation degree (TNF α)in blood. The data were analyzed using multivariate technique (Manova) Hotelling's method (T2). Hypothesis testing using α0.05. The results and conclusions of the study stated that the normal diet had no effect on the variables of sprint running speed, SOD and TNF-α levels. While low-carbohydrate and high-protein diet can increase SOD levels of 211.44 /gHb, reduce (TNF α) at least 0.309 pg/ml, and the average increase in antioxidant activity caused by low-carbohydrate-high-protein diet is 24,989 / gHb higher than normal diet, the decrease in the degree of inflammation is 0.196 pg/ml, however, it has no effect on the speed of sprint.

1. Sixty marasmic children were investigated for the absorption of xylose, proteins and fats. Their duodenal juice samples were also analysed for bile salts and microflora.2. The marasmic children were then studied in three groups of twenty by allocating them to three different dietary schedules: a high-protein diet (30% of the total energy from protein), a high-fat diet (40% of the total energy from fat) and a high-carbohydrate diet (70% of the total energy from carbohydrate) for 2 weeks and the previous measurements repeated.3. Whereas the high-fat diet resulted in improved fat absorption, along with an increase in total and conjugated bile acids, and the high-carbohydrate diet led to improved xylose absorption, the diet rich in protein resulted in an improvement in the absorption of all three dietary ingredients. It appears that a high-protein diet improves the overall absorption process by improving the intestinal environment as a whole, while high-carbohydrate and high-fat diets bring about adaptive changes related to the respective absorptive processes.

Hyperuricemia is a central risk factor for gout and increases the risk for other chronic diseases, including cardiometabolic disease, kidney disease, and hypertension. Overproduction of urate is one of the main reasons for hyperuricemia, and dietary factors including seafoods, meats, and drinking are contributed to the development of it. However, the lack of a suitable animal model for urate metabolism is one of the main reasons for the delay and limitations of hyperuricemia research. Combining evolutionary biological studies and clinical studies, we conclude that chicken is a preferred animal model for hyperuricemia. Thus, we provided chickens a high-protein diet (HPD) to evaluate the changes in the serum urate levels in chickens. In our study, the HPD increased the serum urate level and maintained it at a long-term high level in chickens. Long-term high serum urate levels induced an abnormal chicken claw morphology and the precipitation of monosodium urate (MSU) in joint synovial fluid. In addition, a long-term HPD also decreased the glomerular filtration rate and induced mild renal injury. Most importantly, allopurinol and probenecid displayed the positive effects in decreasing serum urate and then attenuated hyperuricemia in chicken model. These findings provide a novel model for hyperuricemia and a new opportunity to further investigate the effects of long-term hyperuricemia on other metabolic diseases.
