Dietary Tips and Rationale

Explanation of Dietary Guidelines > Diet > Outline

Eat meals and snacks at regular times every day


See Possible Strategies

  • Less tendency to over eat next meal
    • Particularly if meal is higher fat
    • Less probability to eat easily accessible calorie dense snacks
  • Regular eating may keep metabolism high
    • Particularly digestion of higher fiber foods
    • Thermoneogenesis: calories converted to body heat
  • Maintains energy level throughout day
    • Potentially higher caloric expenditure during activity
  • Improve serum profile
    • Reduced fasting circulatory concentrations of cholesterol, low-density-lipoprotein (LDL), and apolipoprotein B (Jenkins 1989, Jones 1993)
    • Reduced circulating insulin concentrations (Jenkins 1989. Jones 1993)
  • Reduced mean 24-hour urinary cortisol excretion (Jenkins 1989)
  • Possible decrease of BMI and waist circumference over time
    • Girls with a lower initial frequency of eating had greater increases in BMI and waist circumference across 10 years of adolescence (Ritchie 2012).

Counter Argument

Eating a high fat, low carbohydrate diet offers longer satiety thus frequent feedings are not required.

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


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).

Eat fruits or vegetables

Eat high fiber foods

Possible Strategies

Moderate dietary fat


Possible Strategies

Counter Arguments

Limit sugar consumption

Possible Strategies

Eat a variety of foods

  • Better insures ingestion of all essential nutrients
  • Decreases risk of developing food intolerances
