TLDR
It is indicated that short-term energy deficits induced by exercise initially prompt a compensatory response by chronic but not acute hormonal regulators of appetite and energy balance within this 24h time-frame however there is no conscious recognition of the perturbation to energy balance.About:

BRIEF COMMUNICATION ARISING: Gut hormone PYY3-36 physiologically inhibits food intake
Rachel L. Batterham,Michael A. Cowley,Caroline J. Small,Herbert Herzog,Mark A Cohen,C. L. Dakin,Alison M. Wren,Audrey E. Brynes,Malcolm J. Low +8 more
TL;DR: The authors showed that post-prandial elevation of PYY3-36 may act through the arcuate nucleus Y2R to inhibit feeding in a gut-hypothalamic pathway.

Effects of exercise intensity on plasma concentrations of appetite-regulating hormones: Potential mechanisms
TL;DR: Blood redistribution during exercise may be important for suppressing ghrelin, while other mechanisms involving cytokine release, changes in plasma glucose and insulin concentrations, SNS activity, and muscle metabolism likely mediate changes in the anorexigenic signals PYY and GLP-1.

Acute and Chronic Effects of Exercise on Appetite, Energy Intake, and Appetite-Related Hormones: The Modulating Effect of Adiposity, Sex, and Habitual Physical Activity.
James L. Dorling,David Broom,Stephen F. Burns,David J. Clayton,Kevin Deighton,Lewis J. James,James A. King,Masashi Miyashita,Alice E. Thackray,Rachel L. Batterham,David J. Stensel +10 more
TL;DR: The balance of evidence suggests that adiposity and sex do not modify appetite or energy intake responses to acute or chronic exercise interventions, but individuals with higher habitual physical activity levels may better adjust energy intake in response to energy balance perturbations.

The Unexplored Crossroads of the Female Athlete Triad and Iron Deficiency: A Narrative Review
TL;DR: How iron deficiency may interact with each component of the female athlete triad, that is, energy status, reproductive function, and bone health, is described.

Weight Management for Athletes and Active Individuals: A Brief Review
TL;DR: The concept of dynamic energy balance is reviewed, including two mathematical models developed to improve weight-loss predictions based on changes in diet and exercise and these models are now available on the Internet.

Effect of weight loss by a low-fat diet and a low-carbohydrate diet on peptide YY levels
TL;DR: Reduced PYY levels after weight loss by an energy- restricted low-fat or low-carbohydrate diet likely represents a compensatory response to maintain energy homeostasis and contributes to difficulty in weight loss during energy-restricted diets.
Journal ArticleDOI
Metformin increases fasting plasma peptide tyrosine tyrosine (PYY) in women with polycystic ovarian syndrome (PCOS)
TL;DR: This study sought to determine whether circulating levels of the anorectic gut hormone peptide tyrosine tyOSine tyrosinate (PYY) show any correlation with metformin‐induced weight loss.
Journal ArticleDOI
Acute exercise increases feeding latency in healthy normal weight young males but does not alter energy intake.
TL;DR: It is confirmed that food intake remains unaffected by exercise in the immediate hours after but suggest that exercise may invoke a delay before food is desired, and energy intake at the first meal consumed, or at subsequent eating episodes.

Glucagon stimulates ghrelin secretion through the activation of MAPK and EPAC and potentiates the effect of norepinephrine.
Jeffrey Gagnon,Younes Anini +1 more
TL;DR: These findings are the first to show a direct link between glucagon and stomach gh Relin production and secretion and highlight the role of MAPK, the PKA-independent EPAC pathway, and the synergy between norepinephrine and glucagon in ghrelin release.

Characterization of the diurnal rhythm of peptide YY and its association with energy balance parameters in normal-weight premenopausal women.
TL;DR: It is concluded that PYY displays a meal-driven diurnal rhythm and is correlated to RMR, a major contributor to energy expenditure, supporting a role for PYY in energy balance modulation.
