Sentences with phrase «in nitrogen excretion»

However, increasing dietary protein intake may offset the increase in nitrogen excretion and negative nitrogen balance that generally occurs during periods of energy deficiency (13, 14).

A previous study found that this rise in nitrogen excretion after carbohydrate withdrawal is short - lived, however, as both nitrogen balance and LBM retention were observed after a 1 — 2 - wk adaptation to a 0 % cholesterol, 15 % protein, and 85 % fat diet (20).

Researchers in Hawaii found that guppies released in the 1920s drove down native fish populations, perhaps by competing with them for food and living space, and had likely changed the cycle of nutrients in water: Guppy - rich areas showed increased levels of dissolved nitrogen — from ammonium in fish urine and gill excretions — which, in turn, stimulated algae growth.

And in the 5 bicycle racers, daily measurements of protein intake and nitrogen excretion confirmed that lean body mass was effectively maintained across the 4 weeks on the ketogenic diet at 1.75 g / d of protein intake.

One measured fluid, electrolyte, and renal indices of hydration over eleven days of caffeine consumption in human subjects, finding that doses of up to 6 mg caffeine per kilogram of body weight had no effect on body mass, urine osmolality (urine concentration), urine specific gravity (concentration of excreted materials in urine), urine color, urine volume, sodium excretion, potassium secretion, creatinine content, blood urea nitrogen (forms when protein breaks down), and serum levels of sodium and potassium.

Dietary carbohydrate deprivation increases 24 - hour nitrogen excretion without affecting postabsorptive hepatic or whole body protein metabolism in healthy men.

If we equate de facto ketogenic diets with high - protein diets (which is not always correct) then the risks proposed by critics of this type of dietary approach are essentially those of possible kidney damage due to high levels of nitrogen excretion during protein metabolism, which can cause an increase in glomerular pressure and hyperfiltration.12 There is not wide agreement between studies; however, some infer the possibility of renal damage from animal studies, 99, 100 whereas others, looking at both animal models, meta - analyses and human studies, propose that even high levels of protein in the diet do not damage renal function.101, 102 In subjects with intact renal function, higher dietary protein levels caused some functional and morphological adaptations without negative effects.103 There may actually be renal - related effects, but on blood pressure rather than morphological damagin glomerular pressure and hyperfiltration.12 There is not wide agreement between studies; however, some infer the possibility of renal damage from animal studies, 99, 100 whereas others, looking at both animal models, meta - analyses and human studies, propose that even high levels of protein in the diet do not damage renal function.101, 102 In subjects with intact renal function, higher dietary protein levels caused some functional and morphological adaptations without negative effects.103 There may actually be renal - related effects, but on blood pressure rather than morphological damagin the diet do not damage renal function.101, 102 In subjects with intact renal function, higher dietary protein levels caused some functional and morphological adaptations without negative effects.103 There may actually be renal - related effects, but on blood pressure rather than morphological damagIn subjects with intact renal function, higher dietary protein levels caused some functional and morphological adaptations without negative effects.103 There may actually be renal - related effects, but on blood pressure rather than morphological damage.
