“…The association between FFM and EI has previously been shown to be weaker with self‐reported data in comparison with objectively measured EI, but the underlying association remained evident (45). The strength of the association between FFM or RMR and EI in the present data ( r = 0.45 and r = 0.41, respectively) was similar to the values observed in studies using laboratory‐based measurements ( r = 0.22‐0.69) (2,6,11). It is relevant to mention that the current analyses were conducted in women.…”

“…These findings suggest that the associations between FM and EI may change from negative to positive at higher body fatness. While a negative association between FM and EI has previously been reported in lean individuals (7,11), findings in individuals with overweight/obesity often demonstrate no associations (2,3,12,13). These data have been used to argue that, as FM is gained, the inhibitory influence of FM on EI proportionally weakens (9,11).…”

“…Understanding energy balance and the factors that lead to its dysregulation is essential to comprehend the etiology of obesity. Some studies have highlighted body composition and energy expenditure (EE) as potential tonic drivers of day‐to‐day energy intake (EI) (1‐3), with associations between fat‐free mass (FFM), resting metabolic rate (RMR), and EI thought to reflect the energetic demand created by metabolically active tissues (4,5).…”

“…Regarding the associations between FM and EI, equivocal findings have been reported. A negative association between FM and EI has been observed in lean individuals (11), but studies in those with overweight/obesity often report no association between FM and EI (2,3,12,13). Overall, these studies suggest that the associations between body composition, EE, and EI may be weaker at higher body fatness, but the potential mechanisms remain unclear, and studies have yet to directly compare these associations between lean individuals and those with overweight/obesity.…”

This study aimed to investigate the influence of body fatness on the associations of body composition and energy expenditure (EE) with energy intake (EI). Methods: Data from 93 women (BMI = 25.5 [SD 4.2] kg/m 2) recruited for two studies (Study 1, n = 48, BMI = 25.0-34.9 kg/m 2 ; Study 2, n = 45, BMI = 18.5-24.9 kg/m 2) were examined. Body composition, resting metabolic rate (RMR), and test meal EI were assessed during a laboratory probe day. Physical activity, total daily EE (TDEE), and self-reported freeliving 24-hour EI were collected during 7 days. Results: In the whole sample, fat-free mass (r = 0.45; P < 0.001), RMR (r = 0.41; P < 0.001), and TDEE (r = 0.39; P < 0.001), but not fat mass (r = 0.17; P = 0.11), were positively associated with free-living 24-hour EI. Body fat percentage moderated the associations of RMR (β = −1.88; P = 0.02) and TDEE (β = −1.91; P = 0.03) with mean free-living 24-hour EI. Fat mass was negatively associated with test meal EI only in the leaner group (r = −0.43; P = 0.004), and a weak nonlinear association was observed in the whole sample (r 2 = 0.092; P = 0.04). Conclusions: Body fat percentage appears to moderate the associations between EE and daily EI. Furthermore, the negative association between fat mass and test meal EI observed in leaner individuals was absent in those with higher body fatness. Therefore, higher levels of body fatness may weaken the coupling between EE and EI.

“…To this end, there is renewed interest in integrative models of energy balance regulation that consider the dynamic relationships between body composition, EE and physiological function, and the way these interactions influence appetite and EI ( 17 – 20 ) . Recent research has focused on the functional associations between components of body composition, EE and EI, and indicate that fat-free mass (FFM) and RMR are associated with a drive to eat that reflects the energetic demand of metabolically active tissue in weight-stable individuals ( 21 – 26 ) . However, it is unclear how changes in body composition and EE during weight loss influence appetite control.…”

Metabolic adaptations during negative energy balance and their potential impact on appetite and food intake

et al. 2019

1This review examines the metabolic adaptations that occur in response to negative energy balance 2 and their potential putative or functional impact on appetite and food intake. Sustained negative 3 energy balance will result in weight loss, with body composition changes similar for different 4 dietary interventions if total energy and protein intake are equated. During periods of underfeeding, 5 compensatory metabolic and behavioural responses occur that attenuate the prescribed energy 6 deficit. While losses of metabolically active tissue during energy deficit results in reduced energy 7 expenditure, an additional down-regulation in expenditure has been noted that cannot be explained 8 by changes in body tissue (e.g. adaptive thermogenesis). Sustained negative energy balance is also 9 associated with an increase in oregixgenic drive and changes in appetite-related peptides during 10 weight loss that may act as cues for increased hunger and food intake. It has also been suggested 11 that losses of fat-free mass could also act as an orexigenic signal during weight loss, but more data 12 is needed to support these findings and the signalling pathways linking fat-free mass and energy 13 intake remains unclear. Taken together, these metabolic and behavioural compensatory responses to 14 weight loss point to a highly complex and dynamic energy balance system in which perturbations to 15 individual components can cause co-ordinated and inter-related compensatory responses. The 16 strength of these compensatory responses is individually subtle, and early identification of this 17 inter-individual variability may help identify individuals that respond well or poorly to an 18 intervention. 19 388 AUTHORSHIP 389 All authors contributed to the writing and editing of the manuscript. 390 391 ACKNOWLEDGMENTS 392The authors would like to acknowledge Professor John Blundell and Professor R.
