Is weight loss all in the mind?
Well, with the danger of oversimplifying a complex topic, this latest research shows it is, and shows precisely how and with what networks. So, what did these researchers find?
The goal of this study was to measure the effectiveness of a behaviour-based (a good old-fashioned diet with restriction of calories) weight loss intervention. This was carried out by Jonathon Burdette and his team – they had previously identified two networks that are related to weight loss. These, called Functional Network 1 and 2 in this study (FN1 or FN2) with FN1 a network related to sensory and motor control and FN2 related to attention and cognitive control.
Participants were scanned in resting state (while doing nothing) and then after completing a food-cue task. They then completed a 6-month programme for weight loss and their results measured and then compared to their brain scans. What did they find?
They found that those who failed to lose weight had higher activity in FN1 in the resting state and lower activity in FN2 after the food-cue task. This may not sound clear but what it actualyl suggetss is those who had trouble losing weight had a higher natural desire to search out and find food in a resting state combined with inhibited or lower emotional regulation, control, and focus in the presence of food.
This therefore suggests that even in resting state the brain is activated differently and rather than a question of simple will power, it is different neural activation patterns – which may be less of a problem “in the wild” but in modern society when there are food cues everywhere, this can be obviously problematic.
The researchers don’t give any tips at this stage, but it is a step forward in understanding some of the challenges and dynamics of weight loss and getting obese in the first place. It also shows that a more individualised approach is necessary because individuals face different challenges.
