As summer vacation time approaches and you’re starting to chase that healthy glow, you might have heard that tanning can help with weight loss and now you are wondering: Is it true? Does tanning help with weight loss? The answer isn’t straightforward—but let’s unpack the important facts using the latest scientific reports and research available.
Because, whether you’re considering indoor tanning, spray tans, or the latest trend red light therapy, or simply spending time in the sun, this article will help you understand if there’s any connection between tanning and fat loss—and whether it’s a great way to reach your healthy weight goals.
Let’s start here. What you need to know.
Tanning, UV Rays & Fat Loss: What Science Really Says
Where does the myths come from that tanning can help you lose weight?
In the early days of tanning trends, there was a common belief that sunlight exposure increased calorie burn or melted away fat. Today, science tells a more complex story.
According to a new study from the University of Alberta Faculty of Medicine and the Alberta Diabetes Institute, UV light exposure—specifically the sun’s blue light wavelengths—may shrink lipid droplets in white fat cells, potentially aiding fat loss. Lipid droplets are fat storage units inside your fat cells. The more white fat you have, the more lipid droplets are present, storing excess energy. These findings suggested a small impact on the basal metabolic rate and energy expenditure.
Your basal metabolic rate (BMR) is the amount of energy your body uses just to keep you alive — breathing, digesting, circulating blood. If L-carnitine helps raise that even a little, it means your body might naturally burn a few more calories each day, even when you’re not doing anything.
And energy expenditure refers to the total number of calories you burn throughout the day, including during workouts, chores, or even fidgeting. While the boost isn’t dramatic, it could help support steady fat loss over time — especially when paired with healthy eating and light movement.
But before you jump into a tanning bed, here’s what you need to know: while this may sound like a giant leap, it’s not a primary method of weight loss. There’s limited scientific evidence to support tanning as an effective fat-burning strategy.
Here’s why.
How UV Exposure Affects Your Body
Let’s break it down for you:
- UV radiation—particularly UVB rays—stimulates the production of melanin (Melanin is the natural pigment responsible for the color of your skin, hair, and eyes. It’s produced by special skin cells called melanocytes, and its main role is to protect your skin from UV radiation). When the production of melanin is stimulated, it causes your skin to darken. It can also increase vitamin D levels, which supports immune system health and muscle mass.
- However, UVA rays, while less intense than UVB, penetrate deeper into the skin but contribute to premature aging and dark spots.
- Some research ties UV exposure to minor shifts in circadian rhythm, energy levels, and even food intake. This could theoretically help regulate increased appetite, but again, it’s not a weight-loss guarantee.
- Blood flow and blood circulation may slightly improve with heat exposure, helping oxygen reach muscles more efficiently during physical activity.
Still, health professionals and the American Academy of Dermatology strongly advise protective measures due to the increased risk of skin cancer.
Now, you might be wondering which one is actually better, tanning beds or red light therapy… or maybe something else?
Tanning Beds vs. Red Light Therapy: What’s the Best Way?
If you’re exploring tanning bed use to target a stubborn fat area, pause.
Because, tanning beds emit high doses of UV radiation, posing a skin cancer risk and increasing chances of skin damage, dark spots, and early aging. In fact, people who begin bed use before age 35 increase their risk of melanoma by 59%. That’s why many states require parental consent for high school students to use tanning beds.
On the other hand, red light therapy is being studied for its impact on fat loss, skin tone, and overall health without the same health risks. While red light therapy is not a miracle solution, there are studies to support that it may help reduce fat in targeted areas and support skin health when combined with strength training, a healthy diet high in protein, and regular sun exposure.
What About Tanning Nasal Sprays and Self-Tanners?
You may have seen a nasal spray marketed to tan your skin while reducing appetite. Honestly, most of these products are unregulated, potentially dangerous, and sold through online retailers with little oversight. There’s no robust scientific evidence that they support weight loss safely.
So, if you’re after a natural glow, opting for self-tanning products and spray tans Instead, offers you a safe tan without the harmful UV damage. These products are ideal for achieving the perfect tan while preserving skin health.
Does Where You Live Matter? (Zip Codes, Sunshine & Vitamin D)
Interestingly, your zip code can influence your vitamin D levels, based on how much healthy sunshine exposure you get.
People in the United States living farther north often have lower vitamin D, impacting mood and even energy levels. Still, these effects are indirect and don’t replace the need for physical activity and a healthy diet for weight loss. I am curious, tell me in the comments where you’re from, I’d love to hear.
Bottom Line: Can Tanning Help You Lose Weight?
Ok, so let’s get real.
Tanning alone—whether via indoor tanning, sunlight, or red light—won’t significantly impact fat loss or weight gain. While sun exposure may support your circadian rhythm (your body’s natural 24-hour internal clock that regulates your sleep-wake cycle, hormone release, eating habits, digestion, and other bodily functions. It responds primarily to light and darkness in your environment), vitamin D, and even influence appetite, the effect on actual calorie burn and muscle mass is minimal without exercise and amino acids from proper nutrition.
So, what is the best way to lose weight? The answer is, combine strength training, a healthy diet high in protein, and movement—not UV rays. Because UV rays carry great risks.
Personally, I love my protein packed meal replacement shakes that are also full of essential vitamins and minerals.
These science-backed, nutrient-dense shakes contains high-quality protein to help push past weight loss plateaus while nourishing your body with essential whole-food-sourced vitamins and minerals. This protein shake covers all your nutritional bases to fuel your body, help build lean muscle, and boost your metabolism, which is great for weight loss.
What I love about them is that they contain 36 grams of high-quality protein, including undenatured whey from grass-fed cows which means it’s untouched and as nature intended.
Risks You Shouldn’t Ignore
Tanning might give a natural glow, but excessive sun exposure dramatically raises your skin cancer risk. The Skin Cancer Foundation urges everyone to use sun protection—including SPF 30+, wide-brim hats, and shade—regardless of whether they tan easily or have a base tan.
As the Seoul National University Hospital and other institutions have shown, early detection and sun protection are essential, especially as types of skin cancers are on the rise.
Just remember:
- Tanning may offer minimal effects on white fat cells through UV-induced metabolic shifts.
- Any weight loss or fat loss effect is small and not reliable for real transformation.
- Risks from UV exposure, especially via tanning beds, outweigh the benefits.
- Opt for spray tans or self-tanning products if you want a healthy glow without damage.
- Focus on sustainable habits: physical activity, healthy diet, bright light exposure (not UV), and protective measures for your skin.
