3 “Healthy” Foods That Are Making You Exhausted
You ate a great breakfast. A smoothie. A protein bar. Maybe some yogurt with granola. You felt fine — for about an hour.
Then the crash hit. The fog rolled in. By 2 PM, you were staring at your screen wondering if it was nap time or if something was seriously wrong.
Your doctor says you’re fine. Your bloodwork is normal. But you’re not fine. You’re exhausted.
Here’s the thing nobody’s telling you: the foods you’ve been told are “healthy” might be the very thing draining your energy. Not because they’re inherently bad — but because of what’s hiding inside them.
Let me show you three of the worst offenders I see every day in my coaching practice.
#1: The “Low-Sugar” Protein Bar
You grabbed it because it said “only 2g sugar” on the front. But flip it over. Somewhere in the ingredient list, you’ll find erythritol, xylitol, maltitol, or sorbitol. These are sugar alcohols — they taste sweet but your body can’t process them efficiently.
For a lot of people, sugar alcohols cause:
- Bloating and gas within 30–60 minutes
- An energy crash 90 minutes later (the “rebound fatigue”)
- Brain fog that lasts for hours
And here’s the kicker: sugar alcohols don’t trigger the same satiety signals as real sugar, so you end up hungrier — not more satisfied.
What to look for instead: Bars sweetened with dates, honey, or maple syrup. Or better yet — a handful of almonds and an apple. Same protein, real energy, no crash.
#2: The “Heart-Healthy” Salad Dressing
You made a beautiful salad. You dressed it with something that said “heart healthy” on the bottle. You felt virtuous.
But that dressing almost certainly contains canola oil, soybean oil, sunflower oil, or safflower oil. These are highly processed seed oils that oxidize during manufacturing, creating compounds that trigger inflammatory responses in your body.
Inflammation = fatigue. It’s that simple. Your immune system is working overtime to deal with the inflammatory cascade from these oils, and the energy drain is immediate and cumulative.
What to look for instead: Dressings made with olive oil, avocado oil, or sesame oil. Or make your own — olive oil, lemon juice, salt, pepper. Thirty seconds, zero hidden ingredients. *side note* I am seeing a decrease in avocado oil quality. Have you noticed it being added to everything recently? Use with caution.
#3: The “Natural” Granola or Yogurt
The yogurt says “made with real fruit.” The granola says “whole grain” and “all natural.” Both are hiding massive amounts of added sugar — sometimes more than a candy bar.
Added sugar under 47 different names appears on ingredient labels. Here are just a few:
- Agave nectar
- Brown rice syrup
- Coconut sugar
- Dextrose
- Evaporated cane juice
- Fruit puree concentrate
- Maltodextrin
- Turbinado
When you eat a yogurt with 19 grams of added sugar (yes, that’s almost 5 teaspoons) plus granola with another 12 grams, you’ve essentially eaten dessert for breakfast. Your blood sugar spikes, your insulin surges, and 90 minutes later — you crash.
What to look for instead: Plain, unsweetened yogurt (Greek or Icelandic skyr are highest in protein) with fresh berries and a drizzle of honey you can actually measure. For crunch: raw nuts instead of granola. *Side note* Greek yogurt is good for you if you can find a brand that is not ultra-processed. Check the ingredients on everything.
The Real Question: Is It YOUR Trigger?
Here’s what I tell every client: these three foods are common culprits, but they might not be YOUR culprit. Everybody reacts differently. Your colleague might eat a protein bar every day and feel great. You might eat the same bar and feel terrible.
The only way to know — really know — is to track what you eat and how you feel for 7 days. Write it down. Every meal. Every snack. Every symptom: energy level, bloating, headache, brain fog, mood, sleep quality.
Within 7–14 days, patterns appear. You’ll see that you always feel tired 90 minutes after your morning smoothie. Or that you’re bloated every Wednesday because that’s when you grab the gas station protein bar on your way to the office.
That data is power. It turns “I feel bad all the time” into “this specific food is causing this specific problem.” And once you know that, the fix is simple.
Want Help Finding Your Triggers?
I’ve helped hundreds of people identify the foods that are draining their energy, causing their bloating, and wrecking their focus — using a simple tracking method I developed after years of struggling with my own food allergies.
Three ways to work with me:
- Grocery Store GPS ($97) — A 45-minute virtual or in-person grocery store walkthrough. I’ll read labels with you in real-time and show you what’s actually in the food you’re buying.
- “What’s Making Me Sick?” 30-Day Reset ($197) — My food-tracking journal, a kickoff call, and three check-ins over 30 days. We’ll find your triggers together.
- “Food Detective” 1-on-1 Intensive ($2,497) — 90 days of personalized coaching, weekly calls, unlimited access to me, and a live grocery store walkthrough.
