Why What You Eat When You Eat Matters | Nutrition Periodization for Tactical Athletes
Nov 03, 2026A nutrition plan that worked five years ago may not make sense for the athlete you are today.
Your body composition may have changed. Your training volume may have changed. Your goals may have changed. Your job may have changed. And yet athletes routinely continue using the same calories, macros, or meal plan regardless of what their training currently requires.
Performance nutrition should support the training outcome you are trying to achieve. That is the basic idea behind nutrition periodization.
Start With the Training Calendar
Before deciding how an athlete should eat, I want to understand what that athlete is doing. When we're building a periodized nutrition program, we may look at an entire 12-month calendar and consider:
▪️ Training goals
▪️ Current nutrition
▪️ Lifestyle
▪️ Schedule
▪️ Current limitations
▪️ Areas that need improvement
▪️ Upcoming events
Then we look at the training. Nutrition gets layered over that training plan.
Why Training Comes First
Performance nutrition exists to support performance. That makes it difficult to appropriately plan nutrition without knowing what you're fueling.
A lower-volume aerobic phase does not necessarily create the same nutrition demands as a high-volume training block involving more speed, power, or high-intensity work.
As those demands change, nutrition may need to change with them.
Carbohydrate Intake Should Reflect the Work
Carbohydrate is one of the most useful variables we can manipulate across a training cycle.
An earlier phase emphasizing body composition, lower-intensity aerobic work, or absolute strength may use a different carbohydrate strategy than a high-volume phase closer to an important event.
As training volume and intensity rise, carbohydrate needs can rise substantially. That is why eating the exact same macros every day for an entire year does not necessarily make sense for a performance-focused athlete.
Fuel the work you're actually doing.
Protein Can Change Too
Protein does not necessarily remain identical across every phase. During a calorie deficit or body-composition phase, protein may represent a larger portion of the nutrition plan.
As training volume increases and carbohydrate demands rise, we may need to make more room for carbohydrate while still maintaining adequate protein.
Again, context matters. The macro targets serve the training goal.
Stop Living in a Calorie Deficit
This is one of the biggest mistakes I see among performance-focused athletes who are also chasing body-composition goals. They start a calorie deficit and refuse to leave it until they reach a specific aesthetic target. Meanwhile, they also want to:
▪️ Get faster
▪️ Get stronger
▪️ Hit PRs
▪️ Recover better
▪️ Increase training volume
Those goals eventually begin competing with chronic energy restriction.
I discuss generally keeping dedicated deficit phases limited rather than dieting continuously throughout the training year. The exact duration and size of a deficit still need to reflect the individual athlete and situation.
If performance is truly the priority, athletes need meaningful periods of adequate fueling.
Put Body Composition in the Right Place
Body composition can absolutely be part of a performance plan. But timing matters. Earlier portions of a long training cycle may provide a better opportunity to address body composition, particularly when training demands are lower.
As you move toward higher-volume training, competition, testing, or other important performance periods, fueling increasingly needs to support the work. Trying to peak performance while aggressively dieting creates unnecessary conflict between goals.
Build the Training Plan, Then Fuel It
- Start with the calendar.
- Lay out the major training phases.
- Identify periods of higher and lower volume.
- Mark important events.
- Identify potential body-composition phases.
- Then layer nutrition over the top.
Your calories, carbohydrates, protein, meal timing, and recovery strategy should reflect what you're asking your body to accomplish during that phase.
Training periodization gives you the roadmap. Nutrition periodization helps provide the fuel to execute it.
Together, they create a much more useful performance system than following the same training and nutrition plan every day of the year.
