Free food-energy guide
Find the meals that fuel your day.
Food is not just calories. A meal can change how full, steady, foggy, bright, or hungry you feel later. Use this guide to notice what a meal seems to do to your next few hours.

Track what happened. Check how it felt. Test the next plate.
The useful question is not whether a food was good or bad. It is what the meal seemed to do to your energy, hunger, focus, and next choice.
-
Log what actually happened.
Meal, portion, timing, hidden sauces, drinks, and what came before.
-
Check how it felt later.
Low, sluggish, steady, or great. Use your lived signal, not a generic rule.
-
Look for the repeat clue.
One meal is a clue. A few normal days can reveal a pattern worth testing.
-
Change the next plate.
Add protein, add fiber, change timing, repeat a steady meal, or shrink a heavy portion.
Not a moral score.
Carbohydrates break down into glucose, a major fuel source. Fiber, protein, fat, portion size, and meal order can change how quickly a meal is digested and how full or steady you feel afterward.
Important: sleep, stress, hydration, caffeine, alcohol, illness, medications, menstrual cycle, and medical conditions can all matter. Use food-energy tracking for general awareness, not diagnosis or treatment.
Four practical clues on the plate.
You do not need perfect tracking — four visible, testable levers do most of the work: protein, fiber-rich plants, carb type and amount, and the size or timing of the meal.
-
Plants
Vegetables, beans, lentils, fruit, and whole grains bring fiber. Fiber helps with fullness and steadier digestion.
-
Protein
Eggs, yogurt, fish, chicken, tofu, beans, and lean meats can make a meal more satisfying and less snack-prone.
-
Carbs
Carbs are not the enemy. The clue is type, amount, and pairing: whole-food carbs with protein and fiber tend to be more useful than a naked sugar hit.
Spot a clue, test one lever.
-
Quick rise, then dip?
Pair carbs with protein and fiber.
-
Very heavy meal?
Test a smaller portion, walk, or vegetable side.
-
Hungry an hour later?
Look for missing protein, fiber, or enough total food.
-
Steady twice?
Save the meal and repeat what works.
A 7-day plan to see what fuels you.
Do not overhaul your diet. Track normal life, then make one small test. The goal is evidence you can use, not a perfect score.
-
Days 1-2
Log normal meals.
Capture food, drinks, portion clues, timing, and anything unusual.
-
Days 3-4
Add energy check-ins.
Mark low, sluggish, steady, or great 1-3 hours after meals — one tap per read.
-
Days 5-6
Test one lever.
Add protein, add fiber, adjust portion, repeat a steady meal, or change meal timing.
-
Day 7
Keep the clue.
Pick one meal to repeat, one meal to improve, and one next-plate idea to test.
Take the worksheet with you.
The same guide as this page in three plain-language pages: what to log, what to look for on the plate, and a 7-day plan to test one change.
