Manipulating Brain Activity and Training Lower Food Consumption Levels
Université de Grenade Researchers Investigate Brain Training and Stimulation to Combat Unhealthy Eating Habits
A research team at the University of Granada is pioneering a novel approach to combat unhealthy eating habits, particularly among those struggling with weight management or binge eating. Their study focuses on the brain's response to tempting food and how it can be modified to promote healthier choices.
People prone to unhealthy eating often find it difficult to adhere to healthy habits, even when they desire to do so. According to the researchers, this issue may stem from the brain's quick response to high-calorie, processed food. The team asserts that when shown such foods, the part of the brain responsible for impulses can activate before the reasoning part has time to react.
To address this challenge, scientists have blended two innovative tools: Transcranial Magnetic Stimulation (TMS), which involves applying magnetic pulses to the brain, and a training method designed to help individuals resist automatic urges. Past research indicates that participants who underwent this combined treatment were more likely to make better food choices and exhibit improvements in their overall eating habits.
The training program incorporates a smartphone application that strengthens a person's ability to resist unhealthy food choices. Through a series of quick, repeatable tasks, the app aims to enhance impulse control, leading to changes in how someone reacts to food cues and ultimately encouraging healthier choices. The researchers believe these techniques can reshape brain activity, particularly in areas involving reward and decision-making.
Emerging research suggests that some individuals react more strongly to food cues than others, particularly those who are overweight. These people may have difficulty ignoring unhealthy options, especially when feeling stressed or tired. The studies also reveal that these reactions often occur so quickly they don't feel like decisions at all; eating becomes an automatic response to sight, smell, or habit, rather than hunger.
In addition to brain stimulation and training, researchers considered various factors, such as body measurements, blood markers, and overall behavior changes. TMS sessions were brief and non-invasive, lasting only 10-15 minutes per day for a fortnight. Participants also underwent brain scans before and after the program to track changes.
The studies form part of an extensive effort to understand the role of brain systems in weight gain and diet failure. The research team has spent over 15 years working on similar projects, frequently collaborating with UK and Australian partners. Unlike traditional health programs that primarily focus on diet and exercise plans, this research suggests that incorporating brain-based training could help individuals stick with their goals.
While each person's brain responds differently to food cues, the researchers continue to explore the impact of genetics, hormones, and emotions on eating patterns. As more is learned about how food choices are shaped by the brain, scientists hope to develop better ways to support those trying to manage their weight, helping them not only initiate healthier habits but maintain them, a challenge that traditional diet programs often struggle to address.
Related Findings:
- Brain Stem Nerve Cells and Semaglutide: A study found that specific nerve cells in the brain stem played a crucial role in reducing appetite and weight through semaglutide, a GLP-1R agonist. This discovery could lead to safer weight loss treatments with fewer side effects.
- Vagus Nerve Stimulation (VNS): Researchers are investigating VNS as a tool for obesity management. By stimulating the vagus nerve, which signals fullness, VNS could help reduce food intake and promote weight loss.
