Poor olfaction is correlated with higher long-term mortality in older adults, particularly in those with good health at baseline. Dementia, Parkinson's disease and weight loss may be possible drivers for the higher mortality rates, but around 70% of cases are unexplained.
According to a new study, women with the APOEe4 allele, a genetic variant closely tied to Alzheimer's disease, face sharper weight loss after the age of 70 than those without the gene, whether they go on to develop dementia or not.
A recent study found 42% of participants gained, on average, 29 lb of unwanted weight during the pandemic, with people gaining 1.5lb per month. Researchers say a combination of stress, hormones, and dwindling motivation to exercise during the lockdowns may be to blame.
A new neuroimaging study found those who achieved greater success at losing weight showed increased activation in regions of the lateral prefrontal cortex, an area of the brain associated with self control.
Losing weight isn't just a case of restricting the foods or calories you eat, it also comes down to when you eat. Skipping breakfast and snacking late at night delays the body's fat-burning mechanisms.
Researchers urge people to reframe negative messages about eating and weight loss for the new year ahead.
