“…Maintenance of the core temperature requires additional energy for thermoregulation during and after exercise if environmental temperatures are outside the thermoneutral zone, either below (cold) or above (warmth/heat) [24]. Indeed, the effects of long-term exposure to extreme environments on energy balance components are well-studied in mammals [25,26,27,28,29]: EI increases to compensate for higher EE to maintain internal temperature in cold environments and EI and EE both decrease in hot environments to avoid heat production and any subsequent increase in internal temperature. Moreover, thermoregulation and the regulation of food intake are both controlled by the hypothalamus [30,31,32], suggesting a strong interaction between these two systems.…”

Understanding the regulation of human food intake in response to an acute exercise session is of importance for interventions with athletes and soldiers, as well as overweight individuals. However, the influence of hot and cold environments on this crucial function for the regulation of body mass and motor performance has not been summarized. The purpose of this review was to exhaustively search the literature on the effect of ambient temperature during an exercise session on the subsequent subjective feeling of appetite, energy intake (EI) and its regulation. In the absence of stress due to environmental temperature, exercise-induced energy expenditure is not compensated by EI during an ad libitum meal following the session, probably due to decreased acylated ghrelin and increased peptide tyrosine tyrosine (PYY), glucagon-like peptide 1 (GLP-1), and pancreatic polypeptide (PP) levels. No systematic analysis has been yet made for major alterations of relative EI in cold and hot environments. However, observed eating behaviors are altered (proportion of solid/liquid food, carbohydrate/fat) and physiological regulation appears also to be altered. Anorexigenic signals, particularly PYY, appear to further increase in hot environments than in those that are thermoneutral. Ghrelin and leptin may be involved in the observed increase in EI after exercise in the cold, in parallel with increased energy expenditure. The potential influence of ambient thermal environment on eating behaviors after an exercise session should not be neglected.

“…Even more to the point of macronutrient and caloric influences on lifespan, Donhoffer and Vonotzky (1947) reported a choice experiment allowing white mice to modulate both intake amount (calories) and preference (macronutrients) by offering three diets with different macronutrient compositions (Donhoffer & Vonotzky, 1947). Upon housing at typical room temperature for approximately 2–3 weeks, intake stabilized with approximately 2/3 of calories chosen from the fat (lard) diet, with lower amounts of protein (casein) and carbohydrate (cornstarch) diets.…”

“…Lowering T a (to 10–11°C) resulted in an increase in caloric intake, albeit this was accounted for primarily from additional carbohydrate consumption with protein intake remaining stable. Furthermore, shifts from low to high T a (29–33°C) primarily suppressed carbohydrate intake, with again stable intake of protein and fat (Donhoffer & Vonotzky, 1947). These intake responses are in contrast to a “no choice” scenario where lower T a still induces increased food intake, but proportionally across macronutrients based on the singular diet composition (e.g., to normal ‘low fat’ chow or semi-purified rodent diets), while a macronutrient choice scenario modulates caloric needs based on altered carbohydrate intake (Donhoffer & Vonotzky, 1947; Leshner et al , 1971).…”

Similar observations have been reported with activity (exercise) preferentially modulating carbohydrate intake in rodents (Collier et al, 1969).…”

The impact of calorie amount on aging has been extensively described; however, variation over time and among laboratories in animal diet, housing condition, and strains complicates discerning the true influence of calories (energy) versus nutrients on lifespan. Within the dietary restriction field, single macronutrient manipulations have historically been researched as a means to reduce calories while maintaining adequate levels of essential nutrients. Recent reports of nutritional geometry, including rodent models, highlight the impact macronutrients have on whole organismal aging outcomes. However, other environmental factors (e.g., ambient temperature) may alter nutrient preferences and requirements revealing context specific outcomes. Herein we highlight factors that influence the energetic and nutrient demands of organisms which often times have underappreciated impacts on clarifying interventional effects on health and longevity in aging studies and subsequent translation to improve the human condition.
