Diets For Chronic Fatigue Syndrome: What Helps, What Hurts
Healthy’s Summary
If you’re dealing with constant exhaustion, brain fog, or body aches that just won’t quit, you’re not alone. Chronic fatigue syndrome (CFS), also known as myalgic encephalomyelitis (ME/CFS), is a complex condition that affects how your body makes and uses energy. And while there’s no one-size-fits-all cure, your diet can play a huge role in how you feel day-to-day.
A well-planned diet for chronic fatigue syndrome can help reduce inflammation, support gut health, and stabilize energy levels. On the flip side, certain foods might be making your symptoms worse without you even realizing it. We’ll break down what helps, what hurts, and what might be worth trying if you’re navigating life with CFS.
What is the Best Diet for Chronic Fatigue Syndrome?
There isn’t a single “CFS diet” that works for everyone, but there are patterns that seem to support people managing this condition. The best diets for Chronic Fatigue syndrome need to help reduce inflammation, keep blood sugar steady, and nourish your mitochondria—the energy factories in your cells.
Helpful foods often include:
- High-quality protein (like eggs, legumes, chicken, tofu)
- Healthy fats (think olive oil, avocados, nuts, fatty fish)
- Complex carbs (sweet potatoes, oats, brown rice)
- Antioxidant-rich fruits and veggies (especially leafy greens, berries, beets)
- Fermented foods (like kefir, kimchi, and sauerkraut) to support gut health
Several studies suggest that people with CFS have altered gut microbiomes, which may influence immune function and energy metabolism source: NIH.
Hydration matters, too. Some people with ME/CFS have low blood volume or issues regulating blood pressure. Drinking water with a pinch of salt or electrolyte supplements can help stabilize symptoms like dizziness or weakness source: Mayo Clinic.

What Foods Make Chronic Fatigue Syndrome Worse?
If you’re trying to eat for energy, some foods might be secretly zapping your reserves. Here’s what to watch out for:
- Refined carbs and sugars (white bread, soda, candy): cause energy crashes
- Ultra-processed foods (think chips, frozen meals): promote inflammation
- Alcohol and caffeine: can disrupt sleep and tax your nervous system
- Food sensitivities: gluten, dairy, and histamine-containing foods can be culprits for some—keeping a symptom journal helps identify triggers
Many people with ME/CFS also experience something called post-exertional malaise—a worsening of symptoms after physical or mental activity. Foods that spike and crash blood sugar can make this even worse. So can inconsistent meal timing.
Interestingly, low blood sugar symptoms (like shakiness, irritability, or mental fog) can mimic or amplify fatigue. So steady, predictable meals are your friend.

Can Supplements Help Chronic Fatigue?
Sometimes, yes—but always talk to a healthcare provider first. Nutritional deficiencies can compound fatigue. The most commonly recommended supplements include:
- B vitamins, especially B12 and B6
- Magnesium, for energy metabolism and sleep
- Coenzyme Q10, a compound that supports mitochondria
- Omega-3 fatty acids, for inflammation
- L-carnitine, which helps transport fatty acids into cells for energy
Some small studies show promise, but evidence is still emerging. A functional medicine provider or registered dietitian can help tailor supplements to your specific needs.
The Takeaway
There’s no miracle food that erases chronic fatigue—but eating with intention can absolutely change how you feel. Focus on nourishing your gut, steadying your energy, and minimizing inflammatory foods. Even small shifts can make a big difference over time. And if it feels overwhelming? Start with one swap at a time. That’s where real momentum builds.
