Activation of CB1 cannabinoid receptors stimulates orexin A release, increasing food consumption. The findings suggest potential targets for new treatments to address obesity.
A study published in Obesity found that the body's internal clock regulates hunger, increasing appetite for sweet, starchy and salty foods in the evenings. This natural tendency can lead to weight gain due to impaired sugar tolerance and energy storage in the evening, rather than expending energy after a morning meal.

In mouse models and human studies, reversing this imbalance protected against weight gain, metabolic problems, and inflammation.
Research published in The FASEB Journal found that sildenafil promotes healthy expansion and browning of white adipose tissue. This is achieved through the inhibition of cyclic GMP breakdown, which reduces pro-inflammatory hormones and shifts fat storage to 'brown' type.
New research using mice shows that disrupting our internal clocks can lead to a complete absence of 24-hour bodily rhythms, resulting in immediate weight gain. Proper sleep patterns are critical for healthy metabolic function, and even mild impairment in circadian rhythms can have serious health consequences.
Researchers confirm that obesity leads to a decrease in physical activity over time, with obese participants showing an 8% drop in moderate to vigorous activity.
