In 2020, a scoping review by K. Ahern and team found that low protein intake and unstable blood sugar from high-carb diets worsened anxiety by 20-30%, as they disrupt serotonin production and spike stress hormones like cortisol. A 2016 study by K. M. Whitaker showed skipping breakfast raised cortisol levels in women by 15-25%, increasing morning stress and anxiety.

In 2025, A. Al Tamim and a team from King Saud University studied Wistar rats on a high-fat diet to mimic obesity. They gave groups standard chow or high-fat diet, with or without daily Sidr or Talh honey at 500-1,000 mg/kg for 12 weeks, checking weight, blood sugar, hormones, and brain inflammation in the hypothalamic arcuate nucleus.

In 2025, Seyed Mohammad Mousavi and team from Harvard T.H. Chan School of Public Health analyzed data from three large US studies with over 205,000 health professionals followed for nearly 40 years. They tracked potato intake—French fries vs. boiled, baked, or mashed—and diabetes cases, adjusting for lifestyle factors like smoking and exercise. 22,299 people developed type 2 diabetes during the study.

In 2025, health experts from EatingWell reviewed studies on walking after eating. They looked at how even a short stroll, like 15-30 minutes, can help people with or without diabetes by preventing blood sugar spikes, easing digestion, and more. Research showed walking right after meals lowers glycemic response better than before, cutting blood sugar rises by 20-30% in some cases.

A 2025 meta-analysis in Frontiers in Nutrition examined multiple trials comparing ketogenic diets (very low-carb, high-fat) with standard diets in cancer patients. The ketogenic group experienced significantly reduced fat mass and visceral fat, lower blood glucose and insulin, and improvements in LDL, total cholesterol, as well as fatigue and insomnia.
