Whole-body cryostimulation in obesity. A scoping review

Currently available treatments for the management of obesity struggle to provide clinically significant weight loss and reduction of the chronic low-grade inflammatory state in order to reduce obesity-related complications. This scoping review aims to provide an up-to-date picture of the therapeutic effects of Whole-Body Cryostimulation (WBC) in patients with obesity and evidence-based indications for its complementary use in the treatment of obesity. We searched the literature until the end of August 2021, retrieving 8 eligible studies out of 856, all evaluated for their methodological quality using the Downs and Black checklist. Overall, the limited data presented in this review article seem to support the efficacy of WBC as an adjuvant treatment in obesity. The cryogenic stimulus has important anti-inflammatory/antioxidant effects and its effectiveness is directly related to the individual percentage of fat mass and initial fitness capacity, mimicking an exercise-induced effect. Based on the limited results gathered, WBC emerges as a promising adjuvant therapy to reduce systemic inflammation, oxidative stress, abdominal obesity, and body mass. However, the data presented in this review article fail to reach definitive conclusions with regards to the efficacy of WBC in the treatment of obesity. Application of WBC protocols yields the potential to widen the therapeutic armor for the treatment of obesity and obesity-related disorders but larger, high-quality studies are still needed.
