“…The relationship among feeding pattern, meal size, metabolic rate, and satiety remains unclear (73). The metabolic rate is increased by the thermic effect of feeding up to 30% in people with low fat content and increases with the energy content of the meal (74)(75)(76)(77)(78)(79)(80)(81)(82)(83)(84)(85)(86)(87)(88)(89). Significant differences between baseline mean preprandial glycemia (i.e., 15% higher) and values obtained after the experimental treatment was initiated suggest the possibility that metabolic rates also may have differed between the two time periods and the two study groups.…”

SummaryAn increase in energy intake often occurs at weaning. The increase may be due partly to prompting by the caregiver to accelerate the child's weight gain and partly motivated by the palatability of common weaning foods. Increased food intakes initiated during weaning and continued into the second year of life may be associated with chronic, nonspecific diarrhea in selected children. An educational project was designed to reduce intakes augmented by either cause. Reductions were achieved by the regulation of energy‐dense foods in the child's diet and reliance on the child's appetite control to determine meal size. The educational intervention was applied prospectively under nonblinded, controlled conditions. Children, 1 to 2 years of age, with chronic nonspecific diarrhea were assigned randomly to either a treatment or control group. Compliance, food consumption, preprandial glycemia, and outdoor activities were reported by the children's mothers in four 7‐day diaries; symptoms related to the children's clinical condition and anthropometric and biochemical indices of nutritional status were noted at the beginning and end of a 7‐month period. Forty‐four of 53 children in the experimental group maintained compliance, and 44 of 47 children in the control group completed the follow‐up. Energy intake decreased significantly by almost one‐third in the experimental group. Growth, skinfold thickness measurements, and outdoor activities were similar between experimental and control groups over the 7‐month period. Diarrheal episodes occurred in 6, 1, and 2 children in the experimental group at 1.5, 3, and 7 months and in 22, 18, and 15 children in the control group, respectively (p < 0.002). Twenty of 32 parameter of clinical status were more advantageous in the experimental group compared to 9 of 32 in the control group in a comparison of the mean values in the two groups at the final examination (p < 0.05). Serum folate (p < 0.001) also was significantly higher in the experimental group. The described intervention appeared to achieve lower energy intakes in a safe and reproducible manner. It may be a useful tool to prevent overeating and control signs and symptoms associated with chronic, nonspecific diarrhea.

“…This manipulation stimulates lipolysis and enhances the thermogenic activity of BAT in conjunction with a higher colonic temperature. A greater understanding of the interactions between feeding, gut function and thyroid secretion could be of great benefit in the management of pre-term infants, as intravenous administration of nutrients has no effect on plasma concentrations of thyroid hormones, but stimulates activity of the sympathetic nervous system (Weinstein et al 1987). In conclusion, the increased occurrence of premature births and caesarean-section deliveries resulting from changes in clinical practices in Europe and North America is directly contributing to conditions whereby thyroid function can be compromised after birth.…”

“…facilitate the equivalent of intra-uterine gain ( -15 g/kg daily; see this page). Values vary for the energy cost of growth and tissue synthesis of 1 g wet tissue-this is in the region of 5-7 kcal(20-30 kJ)/g; any variation is likely to be related to the type of composition of the tissue laid down, the impact of dietary induced thermogenesis (Morgan & Mumford, 1981) or the variation in the provision of amino acids (Weinstein et al 1987). The day-to-day variation in energy expenditure of the low birth weight (LBW) infant (sick and well) may explain the widely varying growth rates reported in premature infants receiving similar energy intakes (Marks et al 1987).…”
