The Ketogenic Diet and Sport: A Possible Marriage? : Exercise and Sport Sciences Reviews - 0 views

  • It is important to note that, although the blood level of glucose drops, it still remains at a physiological level (23), which is maintained through gluconeogenesis involving glucogenic amino acids and also glycerol released from triglycerides
  • “physiological ketosis” where KB levels may rise to 7 to 8 mmol L-1 (but without any pH change). In “pathological diabetic ketoacidosis,” on the other hand, ketonemia can exceed 20 mmol L-1 and also cause lowering of blood pH
  • in the initial phase of KD, about 16% of glucose comes from glycerol (released from triglyceride hydrolysis) and the bulk (60–65 g) from proteins via gluconeogenesis (proteins may be of either dietary or endogenous origin

  • the protein supply consumed during a KD “preserves,” as demonstrated, lean body mass
  • The importance of glycerol as a glucose source increases progressively during ketosis; in fact, glycerol passes from supplying 16% of total glucose to an average of 60% after many days (>7 d) of complete fasting (from 38% in lean individual to 79% in the obese).
  • The possible reasons for the effectiveness of KD for weight loss may be listed as follows, in order of evidence, strongest first: Figure 3Image Tools 1. Appetite reduction: protein satiety, effects on appetite-related hormones such as ghrelin, and possibly a sort of direct appetite-blocking effect of KB 2. Reduced lipogenesis and increased fat oxidation 3. A reduction in respiratory quotient may indicate a greater metabolic efficiency in fat oxidation 4. A thermic effect of proteins and increased energy usage by gluconeogenesis
  • all data regarding biochemical and molecular mechanisms suggest that it is very difficult to increase muscle mass during a KD; use of which really should be limited to the few days immediately before competition in bodybuilding.
  • a long-term KD can interfere with some muscle hypertrophy mechanisms and this could be counterproductive if the aim of the athlete is to gain muscle mass

    Those with Alzheimer's disease have associated dysfunction of glucose metabolism in the brain, particularly in the hippocampus. It has been reported that a ketogenic diet can improve cognitive function in these individuals. In this study, the ketone bodies were initiated through a diet high in medium chain fatty acids. The ketone bodies served as an alternative fuel source for the brain.

  • The most prevalent types of cognitive impairments include disturbances in attention and learning and memory function
  • An association between BDNF and learning and memory was found when measuring the performance of rats on the Morris water maze task
  • exercise and BDNF have been associated with reducing depression and promoting cognitive enhancement.

  • In addition to reducing oxidative stress and inflammation, DHA serves to improve neuronal function by supporting synaptic membrane fluidity
  • Curcumin has also been shown to protect the hippocampus and to counteract learning impairment
  • insufficient DHA in the brain can compromise neuronal function with subsequent effects on a broad range of neurological and behavioral faculties.
  • Nathan Goodyear on 01 Nov 13
     
    diet and exercise increases BDNF.  Diets rich in omega 3, curcumin, and polyphenols increase BDNF and thus increase neuroplasticity and associated cognition.   In contrast, sugar and saturated fats in crease oxidative stress and worsened spatial learning.  This study is a review.

  • Five branched chain and aromatic amino acids (isoleucine, leucine, valine, tyrosine, and phenylalanine) showed significant associations with future diabetes
  • there is increasing evidence that longer term high-protein intake may have detrimental effects on insulin resistance [68, 117–123], diabetes risk [69], and the risk of developing cardiovascular disease
  • high-protein and the high GI diets significantly increased markers of low-grade inflammation
  • ...5 more annotations...
  • significant and clinically relevant worsening of insulin sensitivity with an isoenergetic plant-based high-protein diet
  • healthy humans that are exposed to amino acid infusions rapidly develop insulin resistance
  • longer term high-protein intake has been shown to result in whole-body insulin resistance [68, 118], associated with upregulation of factors involved in the mammalian target of rapamycin (mTOR)/S6K1 signalling pathway [68], increased stimulation of glucagon and insulin within the endocrine pancreas, high glycogen turnover [118] and stimulation of gluconeogenesis [68, 118].
  • it was recently shown in a large prospective cohort with 10 years followup that consuming 5% of energy from both animal and total protein at the expense of carbohydrates or fat increases diabetes risk by as much as 30% [69]. This reinforces the theory that high-protein diets can have adverse effects on glucose metabolism.
  • Another recent study showed that low-carbohydrate high-protein diets, used on a regular basis and without consideration of the nature of carbohydrates or the source of proteins, are also associated with increased risk of cardiovascular disease [70], thereby indicating a potential link between high-protein Western diets, T2DM, and cardiovascular risk.
