The term ‘how to lose belly fat overnight with Vaseline’ has gained popularity online, with many individuals attempting this method. They apply Vaseline to areas like the abdomen, wrap themselves in plastic film, and hope the increased heat will help diminish stubborn fat. However, the excessive sweating caused by Vaseline and plastic wrap is due to the skin’s inability to cool properly, not enhanced metabolism. Therefore, any results are due to temporary water weight loss, not actual fat reduction. 

Vaseline, a form of petroleum jelly, is widely used as a moisturizer with anti-inflammatory properties, but it’s not designed as a weight loss product. Petrolatum seems to help our skin[1] by beefing up its natural protective barrier and boosting its ability to fend off microbes. Its use shouldn’t be misconstrued as a guaranteed solution for losing belly fat.

Can You Lose Belly Fat Overnight With Vaseline?

You cannot lose belly fat overnight with Vaseline. Some of the common treatments are:

  • Step 1: Sleeping with Vaseline on your stomach.
  • Step 2: Exercising with Vaseline on your belly.
  • Step 3: Applying Vaseline with herbs and alcohol.
  • Step 4: Applying Vaseline with instant coffee.
  • Step 5: Applying Vaseline with topical iodine.
  • Step 6: Rubbing Vaseline on your belly before exercise.

Sleep With Vaseline On Your Stomach

Sleeping with Vaseline on your stomach, with or without cling film, is one of the more popular methods for losing tummy fat overnight. However, you will find many sources suggest not just applying the jelly and sleeping in it but also drinking eight glasses of water daily, eliminating sugar and fried food, exercising most days, and continuing this regime over four weeks. 

The results from this method are likely to be from the changes in diet and exercise alone and have nothing to do with the Vaseline on the stomach. The only aesthetic positive to applying petroleum jelly on the skin every night may be that it can reduce dry skin, which may, in turn, look smoother.

Exercise With Vaseline On Your Belly

Another popular method for losing weight is applying Vaseline, with or without plastic wrap, to the belly before a workout. However, the proposition that it aids in burning extra calories for weight loss during exercise is unfounded and has no scientific evidence to back it up.

Many topical creams claim to accelerate belly fat loss during exercise. Some claim to be scientifically supported, but paying close attention to whether a test group exercised with the cream and if another group exercised without the cream is essential. This would likely show that the fat-burning results were attributed to exercise and not to any mystical cream.

Apply Vaseline With Herbs And Alcohol

This method uses a recipe for a slimming cream made with Vaseline, alcohol, rosemary, sage, a camphor tablet, and menthol cream. To prepare, mix alcohol with rosemary and sage, then add the other ingredients after a few hours. Store it in the fridge for 48 hours. Apply the mixture to the abdomen, wrap it in plastic for an hour, then wash off in the shower.

There is some evidence to support menthol as a tool for weight loss. One study[2] concluded that substances like menthol could increase energy usage and reduce animal fats, potentially preventing obesity. In humans, oral menthol showed minimal effects,[3] but applying it on the skin increased body temperature[2] and energy usage. However, no evidence of Vaseline doing the same exists. 

Apply Vaseline With Instant Coffee

This homemade cream recipe claims to reduce belly fat when applied to stubborn areas. The ingredients include Vaseline, sugar, and instant coffee, all blended together. The cream should be applied three times a week and washed off after a few hours.

While some studies suggest caffeine intake is associated with reduced body fat,[4] the available evidence supporting the effectiveness of its topical application[5] is limited and requires additional investigation.

Apply Vaseline With Topical Iodine

Purported as a quick and straightforward method to make a slimming cream, mix Vaseline and iodine, then apply the cream before bed and wash it off in the morning.

While iodine can be absorbed via the skin,[6] no evidence supports it as a topical spot treatment for stubborn fat. Iodine deficiency is associated with hypothyroidism,[7] which can cause weight gain, but supplementing iodine helps if you are deficient, and too much of it can cause issues on its own. Hence, this method is not recommended.

Rub Vaseline On Your Belly Before Exercise

Increasing your body temperature can help to improve your basal metabolic rate[8] and burn more calories. Some suggest rubbing Vaseline on your stomach before exercise, which can help to increase body temperature. However, there is a difference between raising your body temperature and basal metabolic rate internally and increasing body temperature externally. 

Increasing your internal body temperature and basal metabolic rate requires workouts and diet modifications. Increasing your external temperature by simply making yourself hot will result in excess sweating, water loss, and dehydration, not actual weight loss.

Is It Possible To Reduce Belly Fat Using Vaseline Overnight?

There is no credible scientific proof that using petroleum jelly can burn belly fat overnight. It is doubtful that this method will contribute to additional calorie burning during workouts. The misconceptions that increased heat and sweating lead to detoxification and a higher metabolic rate are misguided.

Any immediate weight loss observed after removing Vaseline can be attributed to sweating, resulting in temporary water weight loss that usually returns within a few hours. Stubborn belly fat takes much more time to shift. 

A note of caution: deliberately finding ways to increase sweating, whether at night or during gym sessions, could result in dehydration.

What Is Vaseline Good For?

Vaseline is a brand of petroleum jelly. Petroleum jelly is a mix of mineral oils and waxes[9] that act as a protective barrier on the skin. The barrier attributes of petroleum jelly prevent moisture loss through the skin, thereby keeping the skin moisturized. It effectively treats minor wound healing by helping keep the skin moist as it repairs. It can also be used for dry, chapped lips and skin or even on animal paws if they suffer from painful cracks. 

When shopping for petroleum jelly, quality matters. It should be triple distilled and purified to ensure any toxic contaminants are removed. Some concerns have been raised over mineral oil’s[10] carcinogenic components, but if processed appropriately, it is considered safe, even for use in food products. 

Petroleum jelly may trigger side effects in some people, though this is rare. These side effects include: 

  • Allergies in individuals sensitive to petroleum products. 
  • Acne, as Vaseline, can clog the pores of the skin.
  • Aspiration pneumonia[11] if used in and around the nose and inhaled.
  • Bacterial vaginosis[12] if used as a personal lubricant.
  • Fungal or bacterial skin infections if used on skin that has not been adequately cleaned.

How To Actually Lose Belly Fat

You cannot lose weight overnight. To effectively burn fat, you must embrace a healthy lifestyle encompassing a balanced diet, regular exercise, and specific lifestyle changes. 

Begin by eating healthy with unprocessed foods like lean proteins, whole grains, fruits, and vegetables, and avoiding refined carbohydrates. Pairing this balanced diet with regular cardio activities such as running or cycling and strength training helps burn calories and builds muscle, promoting healthy weight.

Staying hydrated is crucial in controlling hunger and ensuring your metabolism works efficiently. Equally important is getting enough sleep, as lack of it can disrupt hormones that regulate appetite and metabolism, potentially leading to weight gain.

Making mindful dietary choices, such as cutting down on alcohol and sugary drinks, can further support weight loss by reducing your calorie intake. Incorporating high-fiber foods into your diet can help manage your appetite by keeping you feeling full for longer.

Enhance your exercise regimen by integrating cardio and strength training, which boost metabolism and burn more calories.


The scientific community cannot find out how to get a flat stomach overnight using Vaseline. Therefore, it is not possible that applying Vaseline to the belly can result in fat loss. Though it may enhance skin hydration and softness, Vaseline cannot permeate the skin to impact fat cells beneath.

The myth of instant belly fat reduction with Vaseline likely sprang from sources trying to market an effortless solution to a complicated problem. While the promise of immediate belly fat loss with Vaseline is enticing, there are no shortcuts to a fit physique. Genuine weight loss requires patience, labor, and commitment.

By concentrating on a nutritious diet, consistent physical activity, and holistic health, you can meet your weight loss objectives in a healthy and long-lasting manner.

Always seek advice from a personal fitness trainer or a registered dietitian before substantially modifying your diet or workout regimen. They can offer tailored advice considering your specific requirements and health background, ensuring you tackle weight loss safely and efficiently.
