Metabolic characteristics of keto-adapted ultra-endurance runners - Metabolism - Clinical and Experimental - 0 views

  •  
    For endurance athletes, low carb and high fat diet utilizes the high fat oxidation in these athletes compared to a high carb diet.  Glycogen stores did not differ between the two groups.

Metabolic characteristics of keto-adapted ultra-endurance runners - Metabolism - Clinical and Experimental - 0 views

  •  
    full study of previous abstract: low carb and high fat diet found to maintain muscle glycogen equal to high carb diet in endurance athletes.  Endurance athletes have high fat oxidation and this probably only applies to these endurance athletes; I would suspect this high fat oxidation would not be found in other short interval sports i.e. sprinting, football....

Dietary Macronutrient Content Alters Cortisol Metabolism Independently of Body Weight Changes in Obese Men - 0 views

  •  
    Extra-adrenal cortisol production is increased by 11-Beta-HSD1 via low Carb diet.  This is counter to that seen in mice studies.  The fat content of the diet could explain this.  This study looked at men.

Carbohydrates and fat for training and recovery. - PubMed - NCBI - 0 views

  •  
    only abstract available here.  Carbs, particularly high glycemic cars are helpful in recovery.  Carbs in the recovery are ket to restoration of muscle glycogen.  Immediate supplementation aids glycogen restorations compared to > 2 hours.  At 24 hours, there is no difference between early < 2h and delayed >2h; peak glycogen occurs at 24 h in this study.

Effect of Distinct Lifestyle Interventions on Mobilization of Fat Storage Pools: The CENTRAL MRI Randomized Controlled Trial | Circulation - 0 views

  •  
    low carb mediterranean nutrition out performs low fat diet; but both are not served by following weight number.  MRI shows that fat mobilization of the superior low carb mediterranean nutrition plan is not adequately reflected in weight measurement.

  •  
    Carb reduction and increase in vegetable fat appears to be associated with reduction in prostate cancer spread and all-cause mortality

A Review of Very Low Carbohydrate Diets for Weight Loss - 0 views

  •  
    Low carb diets result in significant weight loss. This is a meta-analysis.

JAMA Network | JAMA: The Journal of the American Medical Association | Effects of Dietary Composition on Energy Expenditure During Weight-Loss MaintenanceDietary Composition During Weight-Loss Maintenance - 0 views

  •  
    small study shows that low carb results in greater calories burned in weight loss.  The least calories burned goes to low fat diet.  Many, many studies have show the negative benefits of a low fat diet.

JAMA Network | JAMA: The Journal of the American Medical Association | Effects of Protein, Monounsaturated Fat, and Carbohydrate Intake on Blood Pressure and Serum LipidsResults of the OmniHeart Randomized Trial - 0 views

  •  
    In this study, a high carbohydrate diet was replaced with a diet higher in monosaturated fats.  The result was: a lower carb diet with resultant increase in monosaturated fats resulted in a reduction in triglycerides, reduction in systolic B/P, increase in HDL, and resultant decrease in CVD risk

A Lower-Carbohydrate, Higher-Fat Diet Reduces Abdominal and Intermuscular Fat and Increases Insulin Sensitivity in Adults at Risk of Type 2 Diabetes - 0 views

  •  
    Diet higher in fats and lower in carbs associated with a reduction in weight, fat mass, improved insulin sensitivity, lowered fasting glucose, and a reduction in TNF-alpha

ScienceDirect.com - Physiology & Behavior - The effects of a high-energy diet on hippocampal-dependent discrimination performance and blood-brain barrier integrity differ for diet-induced obese and diet-resistant rats - 0 views

  •  
    We have known that diet and brain inflammation were linked.  This study shows a link between, what they call High energy diet (better known as  high calorie, high fat, high carb...), and altered hippocampus brain function.

Regulation of muscle glycogen repletion, muscle, protein synthesis and repair following exercise - 0 views

  •  
    Nice study and review of other studies that looked at post-exercise recovery strategies. This authors conclusion, and I concur, is that a mixture of carb 0.8 g/kg and protein 0.2 g/kg mixture immediately and 2 hours post is the best to restore glycogen stores and promote an anabolic state

Treatment of Diabetes and Diabetic Complicati... [J Child Neurol. 2013] - PubMed - NCBI - 0 views

  •  
    Only the abstract, but for Diabetics, a ketogenic diet needs to include high fat and low protein.  Especially the elimination of animal protein.  A transition to a high protein diet will reduce ketosis.  The switch to ketosis from glucose will be what improves glycemic control.  The primary increase in most ketogenic or "low carb" diets today is an increase in protein.

Diet-hormone interactions: Protein/carbohydrate ratio alters reciprocally the plasma levels of testosterone and cortisol and their respective binding globulins in man - 0 views

  •  
    small study, but complex carbs found to increase Testosterone more than high protein diet.  That goes against most marketing.  In contrast, cortisol was the opposite.

Dietary carbohydrate restriction as the first approach in diabetes management: Critical review and evidence base - Nutrition - 0 views

  •  
    Excellent article on the ketogenic diet and the treatment of diabetes.   A ketogenic diet here was defined as < 10% carbs

Influence of dietary carbohydrate intake on the free testosterone: cortisol ratio responses to short-term intensive exercise training. - PubMed - NCBI - 0 views

  •  
    excessive carb restriction in athletes can lower Testosterone levels and negatively impact Testosterone to cortisol ratio. This will limit performance and hinder recovery.

Ketone bodies as a therapeutic for Alzheim... [Neurotherapeutics. 2008] - PubMed - NCBI - 0 views

  •  
    Ketone bodies have been shown to benefit the mitochondria in the brains of those with Alzheimer's disease.  This ketosis can be achieved through low carb/protein, high fat diet.
