This finding has significant implications for treating conditions such as type 2 diabetes and aging populations.
A new study published in Cell Metabolism found that eating a larger meal in the morning does not impact energy metabolism but may help with appetite control and satiety. Healthy subjects who followed a morning-loaded diet reported feeling less hungry later in the day.
The study found that pregnant individuals younger than 25 years, non-Hispanic Black individuals, unmarried individuals, and those with obesity before pregnancy experienced higher gestational weight gain. The pandemic also led to a higher risk of excessive gestational weight gain among these groups.
Researchers found that early weight loss is strongly associated with short and medium-term success in weight management programmes. Those who fail to lose at least 0.5% of their body weight after three sessions are unlikely to succeed. The threshold of failing to achieve 0.5% body weight loss was 95% accurate at identifying participant...
Children born to mothers with gestational diabetes and obesity are twice as likely to develop attention-deficit/hyperactivity disorder (ADHD), according to a new study. The researchers found that excessive weight gain during pregnancy was a significant risk factor for ADHD in offspring, but not within normal weight gain ranges.

A new study reveals that areas once 'redlined' in the 1930s continue to suffer from higher rates of cardiometabolic health risk factors, including obesity, diabetes, and high blood pressure. Neighborhoods with lower grades on historical redlining maps had better access to healthcare and lower rates of disease.
A study by Tufts researchers found that only 6.8% of US adults had optimal levels of blood pressure, blood sugar, cholesterol, adiposity, and cardiovascular disease in 2017-2018.
