What is Nutrient Timing?
The application of knowing what to eat and
when to eat before, during and after exercise
Designed to help you achieve your most advantageous exercise performance and recovery
3 Areas of Interest
For exercise lasting less than 45 mins is water fine?
How long after a workout do you have to restore your muscles?
Is CHO the nutrient for aerobic athletes?Is Protein the nutrient for strength
athletes?
Hormones & Exercise
Insulin “anabolic controller”
• Transporter promotes either fat OR protein storage
• glucose uptake, glycogen storage
• protein synthesis & AA transport protein degradation
• cortisol release
How insulin increases net protein gain
3 Phases
1.Energy Phase
2. Anabolic Phase
3. Growth Phase
ENERGY PHASE
-10 mins until end of workout
Multi nutrient supplement (CHO + PRO + MCT) 30 mins prior increased vertical jump power & no. of reps at 80% 1RM
(Kraemer et al 2007)
Health benefits ?MCT (Medium Chain Triglycerides)
High in Lauric AcidAnti viral, anti bacterial, anti microbial
Straight to the liver (readily oxidized)
Increased metabolism (heat!)
Apetite suppressing effectWeight control WHEN used to replace other LCT’sIncreases in muscle? Due to cell membrane ?
Multi nutrient supplement (CHO + PRO + MCT) 30 mins prior increased vertical jump power & no. of reps at 80% 1RM
(Kraemer et al 2007)
it also growth hormone & testosterone
(Protein) 12 week study Strength and lean body mass
(Candow et al 2006)
10 week study body mass fat free mass, IGF1, mRNA,
& myofibrillar protein (Willoughby & Stout 2007)pre & post CHO + PRO + CR lean body mass, 1RM, type II fibres, muscle Cr, PRO synthesis
Cribb et al 2006
Quick word about cardio
Interesting study by (Saunders et al)
ADDING PRO to CHO 29% & 40%
improvement in performance 83% less
muscle damage
Energy phase & strength training
CHO before & during maintains muscle glycogen & enhances the benefits of training (Haff et al)
Baty et al found anabolic hormone insulin & levels of cortisol in CHO & PRO V CHO ALONE
2 studies by Bird et al ;Cortisol 105% in placebo BUT ONLY 11% in CHO & 7% in CHO + EAA levels of 3methyl-histidine reduced by 27%
CHO & PRO 26% markers of PRO breakdown & type I, type iia, type iib cross sectional areas
Effect on muscular endurance
Blunting the effect of cortisol
Bishop et al
Energy phase
ANABOLIC PHASE
The 45 mins window(the most important phase)
Importance of immediate cho/pro supp (anabolic phase)
Levenhagen et al
Effect of supp type on insulin response
Zawadzki et al
Markers of muscle damage
Siefert et al
Don’t Wait !
Ivy et al CHO + PRO + FAT immediately after exercise provoked a greater insulin response
Berardi et al : even greater levels of muscle glycogen resynthesis and protein synthesis when BCAA’s added immediately post exercise
TAKE HOME : increasing concentration of Amino Acids in blood important for promoting increases in lean tissue and improved body compostition
Practical Approach • Consume a CHO +PRO in
3:1 or 4:1 ratio within 30 mins.
This translates into 1.2-1.5gms/kg simple CHO 0.3-0.5gms/kg PRO +
BCAA’s
End of the anabolic phase to the start of next workout
GROWTH PHASE
a. Insulin resistance
b. Prolonged insulin sensitivity
Effect of amino acid level on protein synthesis
Whey vs Casein
Whey fast releasing – better for synthesis
Casein slow releasing better for attenuating protein breakdown
Casein may be better overall for protein balance (Boirie et al 1997)
(dangin et al 2001)
Creatine gives more benefits
(Cribb et al) greater changes in CR + PRO + CHO over CR, CHO or PRO alone. Body mass fat free mass and favourable body comp changes
Content of growth phase supp
ConclusionsProlonged >60-90 mins exercise will deplete
energy and prudent timing can offset this
During intense exercise regular 10-15fl/oz 6-8% CHO should be taken every 10-15mins to sustain blood glucose
Minimize fructose as it can cause GI upset/absorbed slowly
Adding Protein .15-.25g/kg/day to CHO at ALL time points especially post exercise is well tolerated and may promote greater glycogen restoration
Conclusions
6-20g EAA’s 30-40 g of high GI CHO within 3 hours and immediately before exercise significantly stimulates protein synthesis
Daily post exercise ingestion of CHO + PRO increases strength & lean tissue and body fat % during regular resistance training
Whey & Casein differ in kinetic digestion patterns
Conclusions
Adding CR to CHO & PRO facilitates greater adaptations
Inclusion of small amounts of fats (MCT) may help further
Irrespective of timing 3:1 or 4:1 CHO to PRO snacks and feeding promotes recovery
HOT TOPICS….
PROTEIN HOW MUCH?
• Protein– High thermic effect (30% calories used!)– Energy-restriction, coupled with exercise stimulates
gluconeogenesis - PROTEIN NOW USED AS A FUEL WITHIN THE BODY!
– High protein diets best for maintaining LBM throughout energy-deficits (Pikosky et al., 2008; Morita, Y., S. Igawa, et al. 1991)
– Essential for enhancing training adaptations– Leucine supports anti-catabolic effects of insulin, with
MUSCLE/PROTEIN-SPECIFIC EFFECTS (Norton & Layman, 2006)– Increasing Glutamine intake will support immunological
function and oppose inflammatory effects (sacks, 1999)
• “Excessive” is all relative…

physiology;• Potentially altering cortisol• GH production• Alkaline mineral excretion• Individual variance to alkaline

Rao. Plant-based dietary supplement increases urinary pH. Journal of the International Society of Sports Nutrition 2008
Alkaline diets result in a more alkaline urine pH and may result in reduced calcium in the urine, however, as seen in some recent reports, this may not reflect total calcium balance because of other buffers such as phosphate. There is no substantial evidence that this improves bone health or protects from osteoporosis. However, alkaline diets may result in a number of health benefits as outlined below• Increased fruits and vegetables in an alkaline diet would improve the K/Na ratio and may
benefit bone health, reduce muscle wasting, as well as mitigate other chronic diseases such as hypertension and strokes.
• The resultant increase in growth hormone with an alkaline diet may improve many outcomes from cardiovascular health to memory and cognition.
• An increase in intracellular magnesium, which is required for the function of many enzyme systems, is another added benefit of the alkaline diet. Available magnesium, which is required to activate vitamin D, would result in numerous added benefits in the vitamin D apocrine/exocrine systems.
• Alkalinity may result in added benefit for some chemotherapeutic agents that require a higher pH.

From the evidence outlined above, it would be prudent to consider an alkaline diet to reduce morbidity and mortality of chronic
disease that are plaguing our aging population.
One of the first considerations in an alkaline diet, which includes more fruits and
vegetables, is to know what type of soil they were grown in since this may significantly
influence the mineral content.
At this time, there are limited scientific studies in this area, and many more studies are indicated in regards to muscle effects,
growth hormone, and interaction with vitamin D.
Intermittent FastingDoes work for short term body fat loss / weight loss – why?
Long term (women) causes issues / problems hormones, reproductive issues.
Real problems when combined with high intensity “crossfit” etc

CONCLUSIONS:Even short-term (17d) consumption of a paleolithic type diet improves BP and glucose tolerance, decreases insulin secretion, increases insulin sensitivity and improves lipid profiles without weight loss in healthy sedentary humans.
