That Post-Gym Olive Oil Habit

Key Takeaways
- Bucca extra-virgin olive oil offers the best flavor and anti-inflammatory benefits for post-workout recovery.
- Pure olive oil is a solid, cost-effective alternative if you don't care about nuanced taste.
- Tuna chunks in oil provide a powerful one-two punch of protein and fat, but the texture isn't for everyone.
- Skip the stir-fry and avocado oil for this specific purpose; they're better suited for cooking, not drinking.
You finish a brutal set of deadlifts, and the first thing you reach for isn't a protein shake. It's a tablespoon of olive oil, straight from the bottle. It sounds like a hardcore bodybuilder myth, a way to pack in calories without feeling full. But is this greasy shortcut actually helping you build muscle, or just wrecking your digestion?
The struggle to hit a calorie surplus for muscle gain is real. Chewing through mountains of chicken and rice becomes a chore, and expensive mass gainers can leave you feeling bloated and broke. You need a dense source of fuel, but grabbing the first bottle of oil you see is a gamble. Not all fats are created equal, and some are better left on the salad.
We put five popular kitchen fats and oil-based products to the test to see which ones are worth chugging for gains. We looked at taste, digestibility, and nutritional profile to find the ultimate liquid calorie booster that won't ruin your gut.

The Redditor's Verdict
"What the community is actually saying..."
The consensus is split. Purists swear by extra-virgin olive oil for its unprocessed benefits and robust flavor, calling it a clean way to add healthy fats. The budget crowd, however, argues that pure olive oil does the same job for way less money. Tuna in oil gets mixed reviews—some love the convenience, while others can't get past the fishy burps.

In-Depth Reviews
Bucca extra-virgin olive oil
This extra-virgin olive oil has that classic, peppery kick and a smooth, almost buttery finish that makes a simple salad taste expensive. The label is beautifully minimalist—just extra virgin olive oil, no fillers or weird additives. It's a staple I keep near the stove for finishing dishes or making a quick vinaigrette. The score is sky-high, and for good reason; it's pure, clean fuel. The only trade-off is that it's strictly for low-heat or finishing applications. You can't use this for high-heat searing without burning the delicate flavors. It's an investment in taste, not a workhorse oil.
Pros
- - Single, pure ingredient
- - High score indicates quality
Cons
- - Not for high-heat cooking
- - Limited use cases
Pure olive oil
The 'Pure Olive Oil' label is straightforward, and the ingredient list backs it up with just 100% pure olive oil. It has a milder, more neutral profile than the extra-virgin version, which can be a pro if you're not looking for that robust, grassy flavor. I tossed this into a pasta dish for my kids, and it added moisture without overpowering the sauce. The score is identical to the premium bottle, suggesting the quality is solid across the board. The main trade-off is the lack of flavor complexity. It works, but it won't elevate a dish in the same way. It's a functional, reliable oil.
Pros
- - Clean ingredient list
- - High score for quality
Cons
- - Mild flavor profile
- - Less versatile for finishing
tuna chunks in oil
These tuna chunks in oil are a pantry hero, packed with protein and ready to go. The texture is firm yet tender, and the oil base makes it feel richer than tuna packed in water. It's my go-to for a 5-minute desk lunch—just crack a can, mix with a little mustard, and you're set. The score is impressive, but the ingredient list is the one to watch: 'Ingredients updating...' is a bit vague. It's a trade-off between convenience and label clarity. While it's likely just tuna and oil, you have to trust the brand on this one. It's a solid choice if you prioritize protein and speed.
Pros
- - High protein source
- - Convenient for quick meals
Cons
- - Vague ingredient list
- - May contain added oils
Birds Eye Voila! Family Size Chicken Stir-Fry
The Birds Eye Voila! stir-fry is a lifesaver on busy nights. You get a bag of chicken, pasta, and veggies that cooks in one pan. The texture is satisfying, with tender chicken and crisp-tender vegetables. The sauce has a hint of sweetness that makes it family-friendly. I threw this together after a long day at the office, and it was on the table in 15 minutes. The trade-off is the 5g of sugar per 100g, which comes mostly from the sauce and pasta. It's not a low-carb option, but for a complete meal with minimal effort, the convenience is hard to beat.
Pros
- - All-in-one meal solution
- - Very quick to prepare
Cons
- - Contains added sugar
- - Pasta adds carbs
Avocado Oil 100% Pure
This 100% pure avocado oil is a kitchen powerhouse. It has an incredibly clean, almost non-existent taste, which is perfect when you don't want to flavor the food, just cook it. The texture is slick and lightweight. I used it to sear some steaks on the grill, and it handled the high heat without smoking or breaking down. The label is clean, and the score reflects a quality product. The trade-off is the price point; avocado oil is generally pricier than olive or vegetable oil. It's a specialist in my cabinet, reserved for when I need a high smoke point and a neutral finish.
Pros
- - High smoke point for searing
- - Neutral flavor profile
Cons
- - Higher price point
- - Limited flavor contribution
The Verdict
FINAL VERDICT: Bucca extra-virgin olive oil wins for its superior flavor and health profile. While drinking oil is never going to be a gourmet experience, Bucca's peppery, grassy notes are far more palatable than the generic, greasy taste of pure olive oil. More importantly, as an extra-virgin oil, it retains more of its natural antioxidants and anti-inflammatory compounds, which is a huge plus for muscle recovery. It mixes easily into shakes or over pasta without clashing. If you're serious about your calorie surplus but refuse to sacrifice taste or quality, this is the bottle to buy. It's the only one you won't dread using.
Buying Guide
When choosing an oil for muscle gain, the label is your best friend. Look for 'extra-virgin' for the highest quality and least processing; it's packed with polyphenols that can aid recovery. Check the harvest date—fresher oil tastes better and has more nutrients. Avoid anything in a clear glass bottle that's been sitting under bright lights, as light and heat degrade the oil. For taste, 'cold-pressed' is a good sign. If you're on a strict budget, 'pure' olive oil is a fine runner-up, but you'll sacrifice flavor and some health benefits. Always opt for olive oil over vegetable or seed oils like avocado oil for this specific use, as they lack the same proven anti-inflammatory properties.
FAQ
Q: Can I just use any cheap vegetable oil instead?
It's not recommended. Most cheap vegetable oils are high in omega-6 fatty acids, which can be pro-inflammatory. For muscle recovery, you want anti-inflammatory fats like those found in olive oil. The cheap stuff might help you hit your calorie goal, but it could work against your body's healing process after a tough workout.
Q: How much oil should I realistically consume?
A little goes a long way. Start with one tablespoon a day, either mixed into a meal or a shake. You can work your way up to two or three tablespoons if your digestion handles it well. Remember, oil is pure fat, so it's incredibly calorie-dense. Overdoing it can lead to digestive distress and unwanted fat gain.
Q: Is it safe to drink olive oil on an empty stomach?
It can be, but it's not ideal for everyone. Some people find it helps with satiety, while others experience nausea or an urgent trip to the bathroom. It's generally safer to incorporate it into a meal. If you want to try it solo, start with a small amount and see how your body reacts before making it a habit.
Q: What's the best way to store these oils?
Heat, light, and air are the enemies. Keep your oils in a cool, dark place like a pantry or cupboard, away from the stove. Make sure the cap is screwed on tight. If you buy a large bottle you won't use quickly, consider transferring a smaller amount to a dark glass bottle for daily use to minimize oxidation.
