“…Ever since RUBNER [21] observed that below the critical temperature of the fasting animal the thermogenic effect of food decreases in proportion to the fall in ambient temperature, it has been a common teaching that SDA may partially or completely replace the metabolic response to cold. In other words, while within the thermoneutral zone the metabolic effect of food is independent of changes in ambient temperature; in a cold environment, it does not manifest itself as an additional amount of heat, but replaces thermoregulatory heat production induced and controlled by chemical thermoregulation.…”

“…Although earlier and more recent observations [ l , 6,7,8,9,12,17,21,221 indicate that premature infants respond, to some degree, to the ingestion offood or load of amino acids by an increase in heat production, there is no information available regarding the magnitude and thermoregulatory significance of the calorigenic effect of food in a thermoneutral and a heat-losing environment.…”

Specific Dynamic Action in Premature Infants Kept at and Below the Neutral Temperature

The calorigenic effect of an artificial formula, Adapta, was examined in premature infants kept a t and below the neutral temperature. After a preliminary period of 15-30 minutes, a feeding (40-60 ml) was offered or given by gavage. The test feeding was followed by an experimental period of four hours, during which time oxygen consumption and CO, production were continuously recorded by an open circuit method using the Kipp diaferometer.The results of investigations carried out in the zone of thermoneutrality are summarized in table I. The amount of oxygen consumed 30 minutes after ingestion of the formula was already appreciably larger than that corresponding to the basal metabolic rate. At 90 or 120 minutes, the average oxygen consumption was 30 % higher than that a t the preliminary level. Oxygen consumption then fell and had approached the fasting level by the end of the period of observation.I n order to obtain the cumulative effect of thermogenesis, total and basal heat production were calculated for a period of four hours. The average amount of total extra calories was 1.7 kcallkg which, in relation to basal heat production during the same period of time and to the ingested calories, represented an increase of 26.4 and 9.2%, respectively (table VI).The changes in oxygen consumption a t different levels of thermoregulatory heat production in totally and partially swaddled premature infants maintained at 20-22' are shown in tables 11, I11 and IV. The responses are also diagrammatically compared (fig. 4). I t can be seen that the magnitude of specific dynamic action is the same for babies in a thermoneutral and colder environment, despite the difference in the preingestion levels of oxygen consumption. Control experiments in nonfed premature infants revealed that the specific dynamic action of food in a heat-losing environment is not due to muscular activity, but appears in an additive manner and independently of the metabolic increase induced by the cold environment (table V).The summation of the metabolic response to cold and to food was also reflected by the behavior of body temperature. The ingestion of 50 ml of formula stopped the fall in body temperature and even caused a small transient rise during the period of maximum increase in heat production.

“…An increase in metabolic rate associated with ingestion of food has been well documented (1)(2)(3)(4)(5). Recently, a reduced thermic effect of a meal in obese subjects, in comparison with that of normal weight subjects, has been reported, (6)(7)(8)(9)(10).…”

A B S T R A C T The thermic effect of infused glucose and insulin was measured by combining the hyperinsulinemic euglycemic clamp technique with indirect calorimetry, in 10 normal weight volunteers (group I), 7 obese subjects with normal glucose tolerance (group II), and 13 obese subjects with abnormal glucose tolerance or noninsulin-dependent diabetes mellitus before (group IIIa) and after weight loss of 10.8±0.4 kg (group IIIb).During hyperinsulinemia (760-1,100 pmol/liter), total glucose disposal from combined endogenous production and glucose infusion was 545±49, 441±70, 233±35, 231±31 mg/min and energy expenditure changed by +0.476±0.080, +0.293±0.095, -0.114 ±0.063, and +0.135±0.082 kj/min in group I, II, lIla, and IlIb, respectively. The increased energy expenditure correlated with glucose storage (measured cost of processing the glucose: 1.33 kJ/g). In group IIIa there was no increase in energy expenditure in response to glucose and insulin infusions. After therapy (group IIlb) there was a significant recovery (P < 0.05) of the thermic effect of infused glucose although total glucose disposal was unchanged. It is proposed that the recovered thermic effect of infused insulin/glucose is due to the different contributions of gluconeogenesis in the fasting state and during the glucose clamp before and after weight loss. In addition we hypothesize that some of the lower thermic effect of food reported in obese noninsulin-dependent diabetics may be explained by decreased energy expenditure due to a greater suppression of hepatic gluconeogenesis as well as by lower storage rate.
