  • Frequent consumption of foods high in fat and sugar can increase your risk of weight gain and conditions such as heart disease and diabetes.
  • Researchers are still investigating the underlying mechanisms involved in craving foods high in fat and sugar.
  • Studies have found that eating foods high in fat and sugar alters the brain’s reward centers, making them more responsive to these foods and reducing cravings for low-fat foods. Adaptation may increase the risk of obesity.

Consuming a Western diet high in sugar and fat poses many health risks. However, in many cases, these foods are craving and easy to consume.

A recent study published in cell metabolism We investigated how eating high-fat and high-sugar foods alters the brain’s reward center.

Researchers found that participants who consumed high-fat, high-sugar yogurt had fewer cravings for low-fat foods and increased brain responses to foods high in fat and sugar. The results suggest the importance of dietary choices in maintaining a healthy weight.

The nutrients that humans need to survive are obtained through food. Most meals contain fats and sugars that are often needed. However, eating large amounts of certain foods can lead to certain health conditions.

foods high in saturated fat It may increase the risk of stroke and heart disease.of American Heart Association (AHA) suggests that we should limit intake of foods high in saturated fat, such as butter, ice cream, and fried foods. Similarly, sugar It occurs naturally in some foods, but can be added in excess in others. Too much sugar increases your risk of diabetes, weight gain, and heart disease.

Barbara Kovalenko, a non-study author, registered dietitian and nutritional consultant at Rasta, explained: medical news today:

“Regular consumption of foods high in fat and sugar can have several negative effects on health. Foods high in saturated and trans fats can raise cholesterol levels and increase the risk of heart disease. Whole foods high in sugar can lead to weight gain, tooth decay, and an increased risk of developing type 2 diabetes.Not all fats and sugars are bad for you, but eating too much of them can It’s important to remember that it can be harmful. A balanced diet that includes a variety of nutritious foods is key to optimal health.”

Even when people are aware of the benefits of eating foods low in sugar and fat, it can be difficult to make healthier food choices. One is still working to understand the relationship between food choices and brain changes.

Dr. Marc Tittgemeyer, study author at the Max Planck Institute for Metabolic Research, explained the purpose of the study: MNT:

“Studies in rodents show that diet alone can alter preferences and rewire brain circuits. I wanted to understand if there was any possibility of rewiring the human brain circuits.”

The study was a randomized controlled study of 57 individuals who were not overweight. dopaminergic systempathways in the brain involved in motivation and reward behavior.

Researchers divided the participants into two groups. For eight weeks, the first group had him eat high-fat, high-sugar yogurt twice daily. In contrast, the second group had him consume low-fat, low-sugar yogurt twice daily. Other than this, the group continued with their normal diet.

Body weight and metabolic parameters remained approximately the same in both groups. However, other changes have occurred. Participants who ate the high-fat, high-sugar yogurt had a much lower preference for low-fat foods than those who ate the low-fat, low-sugar yogurt. It also increased the brain’s response when consuming with anticipation.

Dr. Tittgemeyer explains the key points of the findings:

“Our study suggests that short-term daily consumption of (high-fat/high-sugar) snacks reduces preference for low-fat foods and rewires the brain’s reward circuitry to enhance responses to palatable foods. Surprisingly, high-fat/sugar snacks did not, not only rewiring brain circuits that respond to food, but also brain circuits important for learning in general. And these effects occur without weight gain.”

Kelsey Costa, a registered dietitian in Dayville, Connecticut, and not the study’s authors, commented on the findings:

“This study suggests that exposure to an unhealthy diet due to lack of access to healthy foods can alter physiology, even in people of healthy weight, leading to unhealthy food preferences and overeating. This study suggests that the food environment in which we live has a significant impact on our dietary habits.

This study had several limitations. First, the study included minimal participants, indicating the need for larger studies in follow-up. Researchers had fairly stringent inclusion criteria, such as having to have a baseline of at least moderate cravings for yogurt and milkshakes.

Results may vary if participants were unwilling to include food or were overweight or obese. This indicates that more diverse research is needed.

Furthermore, the researchers did not examine the individual effects of sugar or fat intake, which limited the results of the study. There is a nature. They also did not examine other dietary intakes of the participants that might have influenced the results. Some authors had declarations of interest included in their papers.

Overall, the results suggest that food choices may contribute to obesity risk because of the way these foods rewire the brain. bottom.

“The most important takeaway message is that diet alone can rewire brain circuits to promote overeating. Eating a lot of food can put you at risk.”

As Kovalenko pointed out, as more research progresses, it may help clinicians approach how to help people maintain a healthy weight:

“These findings highlight the need for more comprehensive strategies to combat HF/HS overdose. [high-fat high-sugar] Help individuals overcome powerful neurobehavioral adaptations that may reinforce unhealthy eating habits as well as weight loss interventions.
