Eat Exercises Sleep

A typical shift worker can feel like they’re “doing everything right” and still wake up hungry, snacky, and low-energy - then wonder why the scale and workouts don’t match their effort. One of the most common reasons is that their carbs, protein, and fats aren’t set to do the jobs they’re supposed to: fuel training, steady appetite, and cover daily energy needs. In other words, it’s not just calories - it’s how those calories are split.

In this chapter, you’ll learn how to set carbs, protein, and fats using a simple approach called the Energy Triangle Macro Model. The goal isn’t perfection; it’s repeatable choices that make your body feel more predictable from meal to meal. You’ll leave with a practical way to build meals around training days vs. rest days, plus clear “stop and get help” warning signs.

Who this is for: anyone who trains (gym, classes, running, strength work) and wants better appetite control and steadier energy - especially if your schedule makes meals inconsistent, like rotating shifts. Key benefits you can expect:

• more stable hunger and fewer “late-day crashes”
• better workout fuel (without feeling overly stuffed)
• a macro setup you can repeat and adjust instead of guessing

Health Foundations: Why Macros Change Energy, Hunger, and Training

Think of your macros - carbs, protein, and fats - as three levers on the same dashboard. Move them in the wrong direction and your engine sputters: you’re either under-fueled for training, over-hungry between meals, or you don’t recover well. Move them in the right direction and your day feels smoother.

Here’s the plain-language “why” behind the outcomes you care about:

1) Carbs are your most direct training fuel. When you use carbs around workouts, your body can pull from glycogen (stored carbohydrate) and blood sugar to power higher-intensity efforts. That can mean better performance, less mid-workout fatigue, and fewer “I can’t finish” moments.

2) Protein supports muscle repair and recovery, and it also helps appetite. Protein increases satiety (feeling full) and gives your body the amino acids it uses to rebuild after training. If protein is too low, people often feel hungrier and recover slower.

3) Fats help with hormones and long-term satiety. Dietary fat slows stomach emptying compared with carbs alone, which can make meals feel more satisfying and last longer. That matters when your schedule makes timing hard.

Now add the shift-work layer. Nia, 34, an ER nurse with rotating shifts, can’t always eat at the same time every day. On some days she’s training in the morning; on others she’s training after a late shift. When her macros don’t match her training demand and her meal timing, she ends up with the classic pattern: she eats carbs but not enough protein, or she “goes light” on carbs but tries to push hard in workouts, or she eats a lot of fat but feels sluggish and misses her training targets.

A few risk factors make macro mismatches show up faster:

1. Irregular meal timing (like rotating shifts)

2. Training that includes both strength and conditioning (needs more consistent fuel)

3. Long gaps between meals (hunger turns into “whatever’s fast”)

4. Low protein intake (often the hidden driver of snacky evenings)

Quick comprehension check: Ask yourself, “When I feel my energy dip, does it happen during workouts, 2-4 hours after meals, or late at night?” The timing often points to whether carbs, protein, or fats need adjusting.

Practical takeaway / reflection prompt: Pick one recent day and note what you ate and when you trained. Then ask: was your macro split helping your workout and your next meal, or fighting your schedule?

Practical Protocol: Set Your Macros Using the Energy Triangle Macro Model

The Energy Triangle Macro Model is simple: you set a “triangle” of carbs, protein, and fats that matches (1) training demand, (2) appetite needs, and (3) daily energy. Instead of chasing exact numbers forever, you start with a repeatable baseline and adjust based on hunger and performance.

Step 1: Choose your protein anchor (start here)

Protein is the easiest macro to get right and the hardest to replace with “willpower.” Aim for 0.7-1.0 grams of protein per pound of body weight per day (or 1.6-2.2 g/kg). If you’re training most days, lean toward the higher end.

For Nia, the difference shows up quickly. On days she hits her protein target, she reports fewer late-shift cravings for quick snacks and better recovery after strength sessions. On days she skips protein to “save room,” she gets hungry faster and her workouts feel flatter.

Step 2: Set carbs for training (then taper on rest days)

Use carbs to support workout intensity, not just to “hit a number.” A practical starting range:

• Training days: 2-3 grams of carbs per pound of body weight (or 4-6.5 g/kg)
• Rest days: 1-2 grams of carbs per pound (or 2-4 g/kg)
