“…Pelletier and co-workers confirmed this result and demonstrated that continuous RF-EMFs exposure for five weeks causes an increased daytime intake of standard chow by 0.22 g/h compared with a non-stimulated control group [23]. However, all data gained from rodents must be considered with caution when compared with our human experiments because RF-EMFs exposure generally irradiates the entire organism of small animals, leading to a considerable systemic heat supply which, in turn, increases the temperature by 0.5 • C [42] and thereby the basal metabolic rate of the whole organism. Such systemic effect certainly influences food intake behavior per se.…”

Obesity and mobile phone usage have simultaneously spread worldwide. Radio frequency-modulated electromagnetic fields (RF-EMFs) emitted by mobile phones are largely absorbed by the head of the user, influence cerebral glucose metabolism, and modulate neuronal excitability. Body weight adjustment, in turn, is one of the main brain functions as food intake behavior and appetite perception underlie hypothalamic regulation. Against this background, we questioned if mobile phone radiation and food intake may be related. In a single-blind, sham-controlled, randomized crossover comparison, 15 normal-weight young men (23.47 ± 0.68 years) were exposed to 25 min of RF-EMFs emitted by two different mobile phone types vs. sham radiation under fasting conditions. Spontaneous food intake was assessed by an ad libitum standard buffet test and cerebral energy homeostasis was monitored by 31phosphorus-magnetic resonance spectroscopy measurements. Exposure to both mobile phones strikingly increased overall caloric intake by 22–27% compared with the sham condition. Differential analyses of macronutrient ingestion revealed that higher calorie consumption was mainly due to enhanced carbohydrate intake. Measurements of the cerebral energy content, i.e., adenosine triphosphate and phosphocreatine ratios to inorganic phosphate, displayed an increase upon mobile phone radiation. Our results identify RF-EMFs as a potential contributing factor to overeating, which underlies the obesity epidemic. Beyond that, the observed RF-EMFs-induced alterations of the brain energy homeostasis may put our data into a broader context because a balanced brain energy homeostasis is of fundamental importance for all brain functions. Potential disturbances by electromagnetic fields may therefore exert some generalized neurobiological effects, which are not yet foreseeable.

“…IRT has been validated as an indicator of stress against SNS parameters and glucocorticoid concentrations [14,[32][33][34][35]. Several studies have applied IRT showing that the technique is feasible in mammals including humans [36], rodents [37][38][39], rabbits [40], dairy cows [41,42], sheep [43], dogs [44,45] cats [46], pigs [47,48], elephants [49], otters [50], horses [51][52][53][54] and non-human primates [21,25,55].…”

“…It is important to note that basal metabolic rate of rodents generally declines with age [Balmagiya and Rozovski, 1983; Gordon, 1993]. Under cool conditions where metabolic rate is elevated above the basal levels that would be observed at thermoneutrality, the energy from RF‐EMR is utilized in place of metabolic energy to thermoregulate in the cold [Gordon, 1987; Taberski et al, 2014]. If ambient temperature is within the thermoneutral zone or wbSAR is too high, the animal cannot lower metabolic rate below basal levels and the RF‐EMR energy leads to a marked heat stress.…”
