The quest for effective weight loss methods has led to various approaches, including the use of neoprene shorts and sauna suits. These garments, designed to trap heat and increase sweating, are often marketed as tools to enhance calorie burning and promote weight loss. However, the scientific evidence supporting these claims is limited and sometimes contradictory. This article delves into the available research and expert opinions to provide a comprehensive overview of the potential benefits and risks associated with neoprene shorts and similar products.
Understanding Rapid Weight Loss and Hot Water Immersion
Rapid weight loss (RWL) is a common practice in sports with weight class restrictions, such as mixed martial arts (MMA). Athletes often employ strategies to reduce body water stores, including hot baths, to meet weight requirements before competition. Hot baths typically involve immersion in hot water followed by wrapping in warm clothing. Some athletes add Epsom salts (magnesium sulfate) to the water, believing it enhances fluid loss.
A study investigated the magnitude of body mass losses during hot water immersion with or without Epsom salts. Eight male MMA athletes participated in a crossover design, performing a 20-minute whole-body immersion followed by a 40-minute wrap, twice in sequence. One visit involved fresh water (FWB), while the other used magnesium sulfate (SWB). Participants restricted carbohydrate, fiber, and fluid intake for 24 hours before each visit.
The study found that body mass losses were similar between FWB and SWB, approximately 1.71 kg and 1.66 kg, respectively, equivalent to about 2.0% body mass. The total body mass loss during the entire RWL protocol was 4.5%. These results suggest that, under the conditions employed, adding Epsom salts did not significantly increase body mass loss compared to fresh water immersion.
Sauna Suits and Calorie Burning
Sauna suits, often made of neoprene or nylon, are designed to trap heat and increase sweat production during exercise. Some manufacturers claim that these suits boost the efficacy of workouts and promote weight loss. However, the evidence supporting these claims is mixed.

One study found that wearing a sauna suit during exercise increased physiological strain and sweat loss. However, it did not conclude whether this translated to improved athletic performance. Another study compared fitness results between participants who wore sauna suits and those who did not. The sauna suit group showed a greater improvement in VO2 max (11.7% vs. 7.3%) and a larger reduction in body weight (2.6% vs. 0.9%) and body fat (13.8% vs. 8.3%).
Despite these findings, it's important to note that the extra calories burned while wearing a sauna suit may be negligible. One study found that sauna suits may help to burn body fat and increase energy expenditure, but the amount of extra calories burned was only 23 per workout.
Safety Concerns and Potential Risks
Using sauna suits and neoprene shorts can pose certain risks, primarily due to the potential for overheating and dehydration. The National Collegiate Athletics Association (NCAA) has banned sauna suits for cutting weight after the deaths of three collegiate-level wrestlers.
Symptoms of heat-related illness include dizziness, faintness, fatigue, headache, heavy sweating, low blood pressure, muscle cramps, and nausea. If these symptoms occur, it's crucial to stop exercising, remove the sauna suit, move to a cool place, and drink plenty of fluids.
Additionally, it's important to dispel the myth that increased sweating leads to detoxification. The human body removes harmful substances through the kidneys and liver, not through sweat.

Expert Opinions and Recommendations
Experts generally advise caution when using sauna suits and neoprene shorts for weight loss. While they may increase sweat production and calorie burning, the potential benefits may not outweigh the risks.
Gary Hunter, a professor at the University of Alabama at Birmingham, notes that neoprene waistbands primarily help rid the body of water, not body fat. He also suggests that overheating can hinder workout performance, making the belts counterproductive for weight loss.
The team at Garage Gym Reviews recommends consulting a doctor before incorporating a sauna suit into your training. It's also advisable to limit sauna suit use to two or three sessions per week, between 5 and 20 minutes each, depending on experience.
Neoprene Materials and Construction
The construction and materials of sauna suits and neoprene shorts are important factors to consider. Most sweat suits are made from anti-rip or tear-resistant materials, such as neoprene and nylon. Neoprene sauna suits are typically machine washable and dryer-safe, while nylon and polyester suits may require air drying or hand washing.
Some sauna suits feature ventilation mechanisms, such as zippers or breathable mesh areas, to help regulate body temperature and prevent overheating.

The Kutting Weight Sauna Suit Study
A study on Kutting Weight sauna suit clothing found that exercise with the suit significantly increased metabolism (20.8%) and facilitated greater weight loss (40.4%) compared to exercise without the suit. The study also showed improvements in energy expenditure and excess post-exercise oxygen consumption (EPOC).
However, it's important to note that this study was sponsored by Kutting Weight, which may introduce bias. While the study reported no adverse events, it's essential to consider the potential risks of overheating and dehydration when using sauna suits.
Alternative Options and Considerations
While neoprene shorts and sauna suits may offer some benefits, there are alternative options for weight loss and fitness that may be safer and more effective. These include:
- Regular exercise: Engaging in a consistent exercise routine that combines cardiovascular activity and strength training can help burn calories, build muscle, and improve overall fitness.
- Healthy diet: Consuming a balanced diet that is rich in fruits, vegetables, lean proteins, and whole grains can support weight loss and improve overall health.
- Hydration: Drinking plenty of water throughout the day is essential for maintaining proper hydration and supporting bodily functions.
