How to Fix Low Energy on a Plant-Based Diet

If you’ve switched to a vegan or plant-based diet and started feeling tired or sluggish, you’re not alone. Low energy doesn’t mean the vegan diet “doesn’t work” — it usually means your nutrition balance needs a small tweak.

1. Eat Enough Calories (Don’t Undereat)

Many new vegans unintentionally eat too little. Whole plant foods are high in nutrients but lower in calories — so if you simply eat the same volume of food you used to, you may be under-fueling your body.

How to fix it:

Add calorie-dense foods like nuts, seeds, avocados, and nut butters.

Increase portion sizes slightly, especially around workouts.

2. Prioritize Protein to Stabilize Energy

Protein isn’t just for muscle — it helps balance blood sugar and keeps you full longer. Without it, you’ll feel drained and hungry all day.

Best vegan protein sources:

Tofu, tempeh, lentils, chickpeas

Quinoa, edamame, and vegan protein shakes

3. Include Complex Carbs (Don’t Fear Them)

Carbs are your brain’s and muscles’ main energy source. The problem isn’t carbs — it’s refined carbs.

Go for:

Oats, quinoa, brown rice, sweet potatoes, whole fruits

Avoid:

White bread, processed snacks, sugary cereals

4. Don’t Skip Healthy Fats

Fats are vital for hormone balance, brain function, and steady energy.

Cutting them too low can cause fatigue, brain fog, and even mood swings.

Add these daily:

1 tbsp flaxseeds or chia seeds

¼ avocado

1 tsp olive or coconut oil

5. Check Micronutrients (Especially B12, Iron & Omega-3)

Nutrient deficiencies are one of the most common reasons for low energy on a vegan diet.

Focus on:

Vitamin B12: take a supplement (crucial for nerve and energy health)

Iron: eat lentils, spinach, pumpkin seeds, and pair with vitamin C

Omega-3: get from chia, flax, or algae oil supplements

6. Hydrate Throughout the Day

Dehydration can mimic fatigue. Aim for at least 2.5–3 liters of water daily, and include hydrating foods like cucumber, oranges, and coconut water.

Pro tip: Add a pinch of salt and lemon to your morning water to replenish electrolytes.

7. Sleep & Recovery Matter

Even with perfect nutrition, lack of sleep drains your energy and slows fat metabolism.

Aim for 7–8 hours of quality sleep — no screens 30 minutes before bed.
