Exercise confers protection against obesity, type 2 diabetes and other cardiometabolic diseases1-5. However, the molecular and cellular mechanisms that mediate the metabolic benefits of physical activity remain unclear6. Here we show that exercise stimulates the production of N-lactoyl-phenylalanine (Lac-Phe), a blood-borne signalling metabolite that suppresses feeding and obesity. The biosynthesis of Lac-Phe from lactate and phenylalanine occurs in CNDP2+ cells, including macrophages… 

Increased Levels of N-Lactoylphenylalanine After Exercise are Related to Adipose Tissue Loss During Endurance Training in Humans With Overweight and Obesity

Higher levels of Lac-Phe after acute exercise were associated with a greater reduction in abdominal adipose tissue during the intervention and could support weight loss in humans.

An exercise-induced metabolite alters feeding

There is an exercise inducible metabolite called Lac-Phe that is increased dramatically with exercise in mammals and acts to reduce food intake and thus also to decrease overall body weight and fat mass, according to a new paper in Nature.

Role of brain-gut-muscle axis in human health and energy homeostasis

The interaction of intestinal microbiota, central nervous, skeletal muscle energy metabolism, and feeding behavior regulation is focused on, which will provide new insight into the diagnostic and treatment strategies for obesity, diabetes, and other metabolic diseases.

Reply to ‘Lactate as a major myokine and exerkine’

Lactate has an integral role in the exercise response and a more fleshed-out description of its impact, and lactate’s meta bolic effects in driving exercise-induced adaptions are described.

The Roles of Gut Microbiome and Plasma Metabolites in the Associations between ABO Blood Groups and Insulin Homeostasis: The Microbiome and Insulin Longitudinal Evaluation Study (MILES)

The A1 haplotype may promote healthy insulin sensitivity in non-Hispanic whites and lactate likely play a role in this process but not selected gut bacteria, as well as potential mediating pathways.

Understanding emerging bioactive metabolites with putative roles in cancer biology

It is proposed that these metabolites could play a bioactive role in promoting or inhibiting cancer cell phenotypes in a manner that is mostly unexplored, either as post-translational modifications (PTMs) on proteins or in, yet unknown ways.

Relationship between leisure-time physical activity and depressive symptoms under different levels of dietary inflammatory index

The findings indicated the mediating role of DII in the association between LPA condition and incident depression, and more well-designed studies are still needed to validate the causal relationship.

Exercise‐induced α‐ketoglutaric acid stimulates muscle hypertrophy and fat loss through OXGR1‐dependent adrenal activation

An unappreciated mechanism for the salutary effects of resistance exercise is revealed, using AKG as a systemically-derived molecule for adrenal stimulation of muscle hypertrophy and fat loss.

Pharmacological but not physiological GDF15 suppresses feeding and the motivation to exercise

It is shown that prolonged, moderate- to high-intensity endurance exercise substantially increases circulating GDF15, in a time-dependent and reversible fashion, to peak levels otherwise only observed in pathophysiological conditions, and that this exercise-induced increase can be recapitulated in mice following forced treadmill running.

Metabolic Signatures of Exercise in Human Plasma

Plasma metabolic profiles obtained during exercise provide signatures of exercise performance and cardiovascular disease susceptibility, in addition to highlighting molecular pathways that may modulate the salutary effects of exercise.

PGC-1α Is Required for Exercise- and Exercise Training-Induced UCP1 Up-Regulation in Mouse White Adipose Tissue

Evidence is provided that exercise training increases U CP1 protein in iWAT through PGC-1α, likely as a cumulative effect of transient increases in UCP1 expression after each exercise bout, and that iWat is more responsive than eWAT in exercise-induced regulation of UCP 1.

A comparison of the metabolic effects of treadmill and wheel running exercise in mouse model

The results suggest that TE and THE AUTHORS may exert beneficial effects in suppressing metabolic risks in mouse model through attenuating body weight, fat mass, size, and increase in mitochondria biogenesis marker, PGC-1α.
