Background—We sought to separately examine the effects of either weight loss or diets varying in protein content and glycemic index without further changes in body weight on cardiovascular risk factors within the Diet, Obesity, and Genes study (DiOGenes). Methods and Results—DiOGenes is a pan-European controlled dietary intervention study in 932 overweight adults who first lost body weight on a...

The Effect of Adding Different Levels Valine in Low Protein Diets on Performance, Blood Parameters and Tibial Bone Properties Ross-308 Broiler Chickens from 8-21 Days

the aim of this study was to investigate the effects of different metabolizable protein levels in diet during the peri parturition on performance and blood parameters of afshari ewes and lambs. thirty two once lambing ewes in the last six weeks of pregnancy and the first six weeks of lactation with diets before and after parturition containing rates of nrc recommended and 20% higher one as low ...

changes in dietary electrolyte balance influence the metabolic fate of protein and many amino acids. furthermore, acid-base condition is achieved in part by the alteration of dietary amino acids pattern and quantity. therefore, a trial was conducted in a completely randomized design to evaluate performance, carcass characteristics, plasma electrolyte and uric acid concentrations of 19 and 28-da...

this study compared the effects of different levels of dietary fat on growth performance, liver enzymes and blood biochemical of juvenile siberian sturgeon (acipenser bearii) was designed for 12 weeks. for this reason 135 fish (15.6 ± 0.33g; mean ± sd) at nine 500 liter fiberglass tanks, each one containing 15 fish. three experimental diets with the same protein (42 %) and 3 fat levels 10, 15 a...

A study was carried out to investigate nitrogen metabolism in response to cecal ligation and colostomy in chickens. We used colostomized plus ceca-ligated chickens fed a low protein diet or a low protein diet supplemented with urea. When both types of diets were fed, nitrogen balance and utilization tended to increase by cecal ligation while total nitrogen excretion tended to decrease. Colostom...

Weight loss can be achieved by any means of energy restriction, but the challenge is to achieve sustainable weight loss and prevent weight 'creep' without increasing the risk of chronic disease. The modest success of low fat diets has prompted research on alternative dietary strategies including high protein diets and low glycemic index (GI) diets. Conventional high carbohydrate diets, even whe...

This study was carried out to investigate the effects of dietary putrescine (PUT) on broiler’s response fed low crude protein (CP) diets. A total of 192 male day old chicks were fed with four dietary treatments including two levels of PUT (0 and 0.03%) and two levels of CP (normal and low) with factorial combinations. Weekly growth performance, nutrient digestibility and intestinal morphology (...

Background: In addition to reducing body weight, the low-calorie diets can reduce the lean body mass. It is hypothesized that in addition to reducing the body weight, the low-calorie diets can maintain the lean body mass. So, the current study aimed at evaluating the effects of high-protein diet with calorie restriction on body composition in overweight and obese individuals. Methods: 36 obese ...
