BACKGROUND Low-carbohydrate, ketogenic diets cause mild, subclinical systemic acidosis. [] Key Method Anaerobic exercise performance was evaluated with the Wingate anaerobic cycling test and the yo-yo intermittent recovery test. RESULTS The diets were matched for total energy (LC: 2333±158 kcal/d; HC: 2280±160 kcal/d; P=0.65) but differed in carbohydrate content (9±1% vs. 63±2% of energy intake; P<0.001).
Anaerobic Performance after a Low-Carbohydrate Diet (LCD) Followed by 7 Days of Carbohydrate Loading in Male Basketball Players
TLDR
Evaluating the effects of a low-carbohydrate diet followed by seven days of carbohydrate loading (Carbo-L) on anaerobic performance in male basketball players found total work, resting values of pH, bicarbonate, and lactate increased significantly compared with the results obtained after the low- Carbohydrate diet.
Effect of a four-week ketogenic diet on exercise metabolism in CrossFit-trained athletes
TLDR
Male CrossFit-trained athletes seem to be more prone to shifts in macronutrient utilization (in favor of fat utilization) during submaximal intensity exercise under a ketogenic diet than are female athletes.
Exercise Training, Intermittent Fasting and Alkaline Supplementation as an Effective Strategy for Body Weight Loss: A 12-Week Placebo-Controlled Double-Blind Intervention with Overweight Subjects
TLDR
Exercise training in combination with IF and alkaline supplementation is an effective strategy to reduce body weight and improve running performance in a 12-week intervention.
Effects of 30 days of ketogenic diet on body composition, muscle strength, muscle area, metabolism, and performance in semi-professional soccer players
TLDR
In this study KD athletes lost fat mass without any detrimental effects on strength, power and muscle mass, and when the goal is a rapid weight reduction in such athletes, the use of a KD should be taken into account.
Dietary Manipulations Concurrent to Endurance Training
TLDR
Over the past 20 years, research has suggested that strategically reducing carbohydrate availability during an athlete’s training can modify the metabolic responses in lieu of simply maintaining a high CHO diet, yet data showing a direct performance benefit is still unclear.
The impact of keto-adaptation on exercise performance and the role of metabolic-regulating cytokines.
TLDR
This review provides new insights into the adaptation period necessary for enhancement in skeletal muscle fat and ketone oxidation after sustained nutritional ketosis and highlights metabolically active growth factors and cytokines, which may function as important regulators of keto-adaptation in the setting of exercise and the KD.
Dietary periodisation for health and performance in world-class endurance athletes
TLDR
This thesis will investigate dietary periodisation approaches in elite endurance athletes as well as the effects of low energy and low CHO availability on direct and indirect outcomes of markers of bone modelling and bone health in this population.
A ketogenic diet for reducing obesity and maintaining capacity for physical activity: hype or hope?
TLDR
The ketogenic diet is a potentially promising diet for reducing obesity while maintaining capacity for physical activity, however, questions surrounding the sustainability of this diet for the long-term remain.
The Effects of 10-Day Exogenous Ketone Consumption on Repeated Time Trial Running Performances: A Randomized-Control Trial
TLDR
In trained subjects, 10 days of ketone salt supplementation does not affect performance in an initial bout of short-distance running, such as during TT1, however, ergogenic effects may be observed under fatigue conditions for example during a repeated running bout.
SPRINTING. . . Dietary Approaches to Optimize Training Adaptation and Performance.
TLDR
Despite the short duration of competitions and relative long-recovery periods between races, nutrition still plays an important role in sprint performance, so too should intake of energy and macronutrients to prevent unwanted weight gain.

The acute reversal of a diet-induced metabolic acidosis does not restore endurance capacity during high-intensity exercise in man
TLDR
These data confirm previous data showing that the ingestion of a low-CHO diet reduces the capacity to perform high-intensity exercise, but it appears that the metabolic acidosis induced by the low- CHO diet is not the cause of the reduced exercise capacity observed during high- intensity exercise under these conditions.
Endurance training on low-carbohydrate and grain-based diets: a case study.
TLDR
Researchers should consider how the potential mediating effect of disruptions to training could influence pretest-posttest designs.
High-protein, low-fat, short-term diet results in less stress and fatigue than moderate-protein moderate-fat diet during weight loss in male weightlifters: a pilot study.
TLDR
A HPLF diet during short-term weight loss may be more effective at mitigating mood disturbance, fatigue, diet dissatisfaction, and stress than a MPMF diet.
The Effects of a Ketogenic Diet on Exercise Metabolism and Physical Performance in Off-Road Cyclists
TLDR
The alterations in insulin and cortisol concentrations due to the dietary intervention confirm the concept that the glucostatic mechanism controls the hormonal and metabolic responses to exercise.
The effects of diet on muscle pH and metabolism during high intensity exercise
TLDR
It is demonstrated that a FP diet can induce metabolic acidosis and may reduce pre-exercise muscle buffering capacity, which may then influence subsequent exercise performance, and that a CHO diet has no influence on muscle glutamine levels after the FP diet.
Effect of low-carbohydrate high-protein diets on acid-base balance, stone-forming propensity, and calcium metabolism.
TLDR
Consumption of an LCHP diet for 6 weeks delivers a marked acid load to the kidney, increases the risk for stone formation, decreases estimated calcium balance, and may increase the risk of bone loss.
Acidosis, but Not Alkalosis, Affects Anaerobic Metabolism and Performance in a 4-km Time Trial
TLDR
Preexercise acidosis, but not alkalosis, affects anaerobic metabolism and PO during a 4-km cycling TT and there was no difference between NaHCO3 and placebo for any of these variables (P > 0.05).
The effects of dietary manipulation on blood acid-base status and the performance of high intensity exercise
TLDR
It is suggested that a predetermined regimen of dietary and exercise variation can significantly affect blood acid-base status and may thereby influence high intensity exercise performance.
Low‐carbohydrate diets: nutritional and physiological aspects
TLDR
The currently available scientific literature shows that low‐carbohydrate diets acutely induce a number of favourable effects, such as a rapid weight loss, decrease of fasting glucose and insulin levels, reduction of circulating triglyceride levels and improvement of blood pressure, while some less desirable immediate effects such as enhanced lean body mass loss and increased urinary calcium loss are reported.
