“…Previous investigators have been unable to maintain nitrogen balance in growing adolescents on balanced, low-energy (3.77-7.11 MJ/day) diets (Heald & Hunt, 1965). In the present study with a protein-sparing modified fast with total energy intakes of 1.41-2.48 MJ/day, nitrogen balance during diet periods was maintained.…”

The Effect of an Energy-Restricted Diet on the Protein Metabolism of Obese Adolescents: Nitrogen-Balance and Whole-Body Nitrogen Turnover

et al. 1980

1. The effect of an energy-restricted (46 kJ day-1 kg-1), adequate protein diet (1.47 g day-1 kg-1) on the nitrogen metabolism of five obese rapidly growing adolescents (two males and three females) was assessed by means of nitrogen-balance measurements and determination of whole-body nitrogen turnover. 2. The energy-restricted diet had no significant effect on nitrogen balance (P more than 0.1) for the entire group when compared with the control dietary intake; however, significant (P less than 0.01) differences in nitrogen balance were noted among individuals at each dietary interval. 3. Mean values for whole-body nitrogen turnover, protein synthesis and breakdown for the control period were: 45.5 +/- 13.2 mg of nitrogen day-1 kg-1, and 5.72 +/- 1.96 and 5.74 +/- 1.92 g of protein day-1 kg-1 respectively. These values are 82% of those measured in infants. 4. Reducing the mean non-protein energy intake to 20 kJ day-1 kg-1 had no significant effect on whole-body nitrogen turnover, protein syn;thesis or protein breakdown. 5. The results are discussed in relation to the regulation of whole-body nitrogen metabolism, by dietary protein and energy intakes.

“…Previous investigators have shown that energy restriction in obese adolescents results in negative balance (Heald & Hunt, 1965). It is clear that a negative nitrogen balance of any appreciable duration can limit growth (Swendseid, 1966).…”

“…HEALD and HUNT [23] have shown that calorie restriction in obese adolescent boys prior to maturation produces a significant negative nitrogen balance when protein intake is maintained. Since increments in calorie intake appear to be related to increments in the number of cells in muscle [8] during adolescence in boys, and since growth hormone is important for cell number increase, it can be suggested that calorie restriction restricts growth hormone influence on muscle cells.…”
