Our research is suggesting that these differences in attention may come down to variations in how our brains prioritise sensory data – a dopamine-driven process called ‘incentive salience attribution’.
我们的研究表明，这些注意力差异可能取决于大脑在处理感官数据优先级时存在差异——这一过程是由多巴胺驱动的，称为“激励显著性归因”。

Para.1
Popular 'weight-loss' diets that are hyper-focused on carbohydrates, like the keto diet, may be doing more harm than good in the long run. Sticking to a low-carb meal plan can help some with diabetes manage their weight and blood sugar levels, but a new study from Australia questions the long-term effectiveness and safety of this approach for those without diabetes.
Para.2
If refined sugars and starches are not replaced with the 'right' foods, the 17-year-long analysis suggests a low-carb diet may actually increase the risk of type 2 diabetes. "A healthy diet is a cornerstone for the prevention and management of type 2 diabetes," write researchers from Monash University and RMIT University, who led the study.
Para.3
The findings suggest that a low-carb diet may result in weight gain in the long run, possibly increasing the risk of developing metabolic disease. This may be "mainly due to the high fat content of the diet (specially unsaturated fat)," the researchers in Australia conclude. Those who reported eating the fewest carbohydrates in the study tended to consume less fiber and eat more protein and fat than those who ate the most carbohydrates.
Para.4
Their study joins several others that have recently questioned the advisability of a keto diet, which promotes a low-carb, high-fat eating pattern. For instance, an analysis published earlier this year found a worrying association between the keto diet and a higher risk of heart disease, stroke, type 2 diabetes, and irritable bowel syndrome.
Para.5
Rigorous evidence suggests that a well-balanced diet is one of the best ways to prevent metabolic disease – and that means making sure a diet is, well, balanced. Cutting out refined sugars and starches is all well and good, but if those carbohydrates are replaced with saturated fats, these new findings suggest it could be creating a whole other problem.
