Prof. William Dalton, Ph.D.Your body's energy systems operate daily according to biological rhythms. Eating at the correct times is energizing. I learned this in my nutrition residency. Eating food out of step with my clock left me drained, no matter how good the food was. Timely eating allows the nutrients to work for you.
Circadian rhythms regulate enzyme secretion. Digestive enzymes peak midday when metabolism is higher. Eating the largest meal first maximizes nutrient digestion. I schedule client lunches between 12:00 and 1:00 p.m. Their energy later stays constant with no slumping. Evening meals digest more slowly because enzymes are diminishing at night.
Breakfast Protocol
- Protein within 60 minutes of waking stabilizes blood sugar
- Triggers metabolism for efficient calorie burning
- Prevents cortisol spikes from delayed eating
Lunch Advantage
- Noon digestion peaks with enzyme production
- Maximizes nutrient absorption from complex meals
- Aligns with natural cortisol dip for efficient processing
Pre-Sleep Fasting
- 3-hour food-free window before sleep
- Allows digestion completion before restorative phases
- Prevents energy diversion to gut during cellular repair
Eating breakfast sets your metabolism for the day. If you eat within an hour after waking up, you won't experience a crash from low blood sugar levels. I eat 2 eggs every morning at 7:00am. This habit stopped my 10:00am tiredness after getting up. Protein rich breakfasts cut afternoon cravings for my clients by 40%.
Dinner should be planned carefully. Stop eating 3 hours before bed for optimum health and vigor. Sleep is the time when the body repairs itself and recycles cells. Digestion is one of the functions competing for the body's resources. Consuming heavy meals late at night can disrupt the production of melatonin. I creak and groan, but I finish dinner by 7.00 pm. The quality of my sleep has improved tremendously.
Distribute the amounts among the meals. Eat 40% of your meals at lunch. Use 25% for breakfast and 35% for supper. I review the client's meals according to this ratio. Their energy is uniform throughout the day. This plan prevents lethargy following meals.
Try changing one timing today. Try having a protein breakfast within an hour of waking. You'll notice the difference in energy tomorrow. Consistency is the key to establishing lasting rhythms. Your body works best on a predictable fuel schedule.
