Adherence
Weight loss interventions, particularly meal replacement with reduced-calorie shakes, can rapidly modify functional brain connectivity, reducing the hyperconnectivity between reward-related regions (NAc, amygdala, OFC, insula) and the dorsolateral prefrontal cortex (dlPFC) in response to food cues.
Consider using meal replacement shakes for a short period (e.g., 3 weeks) as part of a weight loss strategy. This approach may rapidly rewire your brain's response to food cues, reducing cravings and making it easier to regulate eating, potentially more so than standard calorie-restricted diets alone.
Total meal replacement with reduced calorie shakes was associated with reduced dorsolateral prefrontal cortex (dlPFC) connectivity with NAc, amygdala, OFC and insula in response to food cues at post-intervention compared to pre-intervention among individuals with obesity... the effect of meal replacement on functional connectivity was evident after just 3 weeks of intervention.

More from this paper
- Obesity is associated with disrupted functional brain network organization, specifically weakened connectivity in the executive control network (ECN) and enhanced connectivity in the salience (SN) and default mode networks (DMN), which correlates with impairments in self-regulation and reward valuation.Moderate
- Stronger baseline connectivity between the dorsolateral prefrontal cortex (dlPFC) and ventromedial prefrontal cortex (vmPFC) predicts greater weight loss following a dietary intervention, suggesting that this neural pattern facilitates dietary impulse control.Moderate
