Methods Systematic Literature Review For this study, the preferred reporting items for systematic reviews and meta-analyses guidelines were followed Moher et al. Figure 1 —Selection of articles for meta-analysis of fat metabolism when consuming CAF. Statistical Analysis Study data were extracted from text or relevant tables.

If data were not reported elsewhere, figures were used for data extraction. Figures were enlarged, and the mean and variance data presented were measured to the nearest millimeters using the appropriate scale of the figure.

Data from each study were converted into the same format by calculating the effect size ES as the standardized difference in means. where M is the mean, and SD Pooled is the pooled SD Borenstein et al. Results Study Characteristics Ninety-four studies published between and were included.

Figure 2 —Summary ES of the subgroup meta-analyses examining the effects of CAF on fat metabolism during rest and exercise. Subgroup Meta-Analyses Subgroup meta-analyses were used to assess effects of moderator variables as potential underlying explanation for the heterogeneity.

Resting Versus Exercise Conditions Of the independent study populations, data during resting conditions were reported in 13 studies, data during exercise conditions in 34 studies, and during both resting and exercise conditions in 58 studies. Fat Metabolism Assessment Method Five different fat metabolism biomarkers were reported across studies.

Figure 3 —Summary ES of the subgroup meta-analyses examining the effects of CAF on fat metabolism by A fat assessment method and B blood lipolysis metrics versus gas analysis metrics. Other Potential Modifier Variables Figure 4 summarizes the impact of other factors on CAF ES on fat metabolism.

Figure 4 —Summary ES of the subgroup meta-analyses examining the effects of CAF on fat metabolism by A sex, B habitual CAF use, C CAF dose, and D fasting state. Publication Bias Publication bias was assessed by examining a funnel plot of SE versus ES.

Figure 5 —Funnel plot of the ES of CAF on fat metabolism versus the SE. Discussion Our aim was to determine whether CAF increases fat oxidation. Strengths and Limitations With different participant populations and nearly 1, participants included in the analysis, this large sample size allowed for a number of important subgroup analyses to address several key moderator variables considered important for assessing the impact of CAF.

Performance, utiluzation composition, substrate ktilization, cardiometabolic, and day minute-by-minute glucose CGM biomarkers were assessed. We also found that the day mean glucose on HCLF predicted day glucose reductions on LCHF, and the day glucose reduction on LCHF predicted LCHF peak fat oxidation rates. These results: i challenge whether higher carbohydrate intake is superior for athletic performance, even during shorter-duration, higher-intensity exercise; ii demonstrate that lower carbohydrate intake may be a therapeutic strategy to independently improve glycemic control, particularly in those at risk for diabetes; iii demonstrate a unique relationship between continuous glycemic parameters and systemic metabolism. From toathletes competing in the Olympics demonstrated trends for increased carbohydrate intake in and a predominant shift toward high-carbohydrate low-fat HCLF diets in the Olympic games 1 — 3.
