Whole-Body Magnetic Stimulation Reduces Binge-Like Feeding in a Mouse Model of Disordered Eating

Area of Science:

• Neuroscience
• Behavioral Science
• Medical Engineering

Background:

• Binge-like eating is a complex behavior with significant health implications.
• Current treatments for binge-eating behaviors have limitations.
• Novel non-invasive neuromodulation techniques are being explored.

Purpose of the Study:

• To investigate the efficacy of whole-body magnetic stimulation (WB-MS) in a rodent model of binge-like feeding.
• To assess the short-term and long-term effects of WB-MS on food intake and related physiological parameters.

Main Methods:

• A binge-like feeding model was established using intermittent access to a palatable diet in rodents.
• Whole-body magnetic stimulation (WB-MS) was applied during the feeding sessions.
• Food intake (palatable diet and chow), body weight, adiposity, and accumbens c-Fos expression were measured.

Main Results:

• WB-MS transiently reduced palatable food intake during stimulation periods.
• Chow intake remained unaffected by WB-MS.
• Binge-like feeding behavior reemerged after the cessation of WB-MS.
• No significant changes were observed in body weight, adiposity, or accumbens c-Fos expression post-treatment.

Conclusions:

• WB-MS shows transient potential for reducing binge-like eating behavior.
• The anti-binge effects of WB-MS are not sustained after treatment cessation.
• Further research is needed to optimize WB-MS protocols for sustained therapeutic effects in eating disorders.
