A new study highlights how signals from the liver to the brain influence eating patterns tied to our circadian rhythms. This liver-brain communication can become disrupted in people working night shifts or irregular hours, leading to weight gain and metabolic issues.

Ultra-processed foods are linked to accelerated biological aging, as confirmed in a study analyzing over 22,000 people. Researchers found that these foods, high in additives and preservatives, speed up the body’s internal aging clock, independently of nutritional quality.

A new study found that calorie restriction, rather than intermittent fasting, had the greatest impact on extending lifespan in mice. Surprisingly, the mice that lived the longest maintained stable body weight and energy levels despite eating less, while those that lost significant weight had shorter lifespans. The findings indicate that genetic factors and resilience to stress play crucial roles in how dietary changes impact health and longevity.

A recent study using mathematical models suggests that breakfast choices may affect men’s and women’s metabolisms differently. Results indicate that men’s metabolisms respond better to carb-heavy breakfasts, while women’s bodies benefit more from higher-fat options like eggs or avocados, especially after fasting.

A recent study has mapped how molecules in food interact with gut bacteria, revealing why people respond differently to the same diets. By examining 150 dietary compounds, researchers found that these molecules can reshape gut microbiomes in some individuals, while having little effect in others.

A new study reveals that a high-fat diet alone does not appear to be responsible for changes in brain neurons that regulate appetite and energy balance. Researchers found no immediate effect on neurons in the hypothalamus of mice fed a high-fat, low-sugar diet, suggesting that other nutrients like sugar may play a more significant role in altering brain function.
