Eating disorders such as anorexia nervosa, bulimia, and binge eating disorder affect approximately 5-10 percent of the general population. Researchers have demonstrated the involvement of a protein produced by some intestinal bacteria that may be the source of these disorders. Antibodies produced by the body against this protein also react with the main satiety hormone, which is similar in structure. According to the researchers, it may ultimately be possible to correct this mechanism that causes variations in food intake.
Eating breakfast increases brain chemical involved in regulating food intake, cravings
Eating breakfast, particularly meals rich in protein, increases young adults’ levels of a brain chemical associated with feelings of reward, which may reduce food cravings and overeating later in the day. Understanding the brain chemical and its role in food cravings could lead to improvements in obesity prevention and treatment.
Brain circuit that controls compulsive overeating and sugar addiction discovered
Compulsive overeating and sugar addiction are major threats to human health, but potential treatments face the risk of impairing normal feeding behaviors that are crucial for survival. A new study reveals a reward-related neural circuit that specifically controls compulsive sugar consumption in mice without preventing feeding necessary for survival, providing a novel target for the safe and effective treatment of compulsive overeating in humans.
Researchers identify peptide that reduces urge to eat
Researchers have identified a peptide and hormone that when administered to a specific area of the brain may reduce the desire for food. The study may one day lead to medications that treat obesity and binge eating disorders.
Obesity is associated with brain’s neurotransmitters
Researchers have revealed how obesity is associated with altered opioid neurotransmission in the brain. New research reveals how obesity is associated with altered functioning of brain’s opioid system, which is intimately involved in generating pleasurable sensations. The researchers found that obesity was associated with significantly lowered number of opioid receptors in the brain. However, no changes were observed in the dopamine neurotransmitter system, which regulates motivational aspects of eating.
People with anorexia, body dysmorphic disorder have similar brain anomalies
People with anorexia nervosa and with body dysmorphic disorder have similar abnormalities in their brains that affect their ability to process visual information, a new study reveals. People with anorexia have such an intense fear of gaining weight that they starve themselves even when they are dangerously thin. Body dysmorphic disorder is a psychiatric condition characterized by an obsessive preoccupation with a perceived flaw in physical appearance.
‘Bad’ genes lead teens to binge-eating
Binge-eating in teenagers may be linked to a gene variation, according to new research.
Even moderate picky eating can have negative effects on children’s health
Picky eating among children is a common but burdensome problem that can result in poor nutrition for kids, family conflict, and frustrated parents. Although many families see picky eating as a phase, a new study finds moderate and severe picky eating often coincides with serious childhood issues such as depression and anxiety that may need intervention.
Gut bacteria population, diversity linked to anorexia nervosa
Studying the ‘gut-brain axis,’ researchers find evidence of an association between the gut microbiota and the eating disorder anorexia nervosa.
Key differences in brain activity in people with anorexia nervosa revealed by study
When people with anorexia nervosa decide what to eat, they engage a part of the brain associated with habitual behavior. These findings open up entirely new avenues for treatment development and understanding of disease mechanisms, say the researchers.
Have an apple-shaped body? You may be more susceptible to binge eating
Women with apple-shaped bodies — those who store more of their fat in their trunk and abdominal regions — may be at particular risk for the development of eating episodes during which they experience a sense of ‘loss of control,’ according to a new study.
Surprising links between bullying and eating disorders
Being bullied in childhood has been associated with increased risk for anxiety, depression and even eating disorders. But according to new research, it’s not only the victims who could be at risk psychologically, but also the bullies themselves.
