Eat 3-6 Meals

Rationale (ISSN Position Stand on Meal Frequency)

See Possible Strategies

  1. Increasing meal frequency does not appear to favorably change body composition in sedentary populations.
  2. If protein levels are adequate, increasing meal frequency during periods of hypoenergetic dieting may preserve lean body mass in athletic populations.
  3. Increased meal frequency appears to have a positive effect on various blood markers of health, particularly LDL cholesterol, total cholesterol, and insulin.
  4. Increased meal frequency does not appear to significantly enhance diet induced thermogenesis, total energy expenditure or resting metabolic rate.
  5. Increasing meal frequency appears to help decrease hunger and improve appetite control.

Eat higher carbohydrate meal (with protein) very soon after exercise

Rationale

See Guidelines

  • Improves post workout recovery (Niles 2001)
    • Faster rate of muscle glycogen re-synthesis
      • 50% more glycogen can be stored (Friedman 1991)
    • Improved performance in subsequent exercise
    • Less muscle damage
  • Increased protein synthesis
    • Nearly 3 fold increase (Levenhagen 2001)
    • Decreases post exercise cortisol levels
  • Increase lean muscle mass (Esmarck 2001, Holm 2004)
  • Decreases risk of injury (Flakoll 2004)

Counter Argument

  • Ingestion of sugar (glucose) has shown to acutely depress testosterone by 25% (Iranmanesh 2012, Caronia 2013).
