Visceral Fat: A Central Risk Factor
When it comes to health, where fat accumulates is more important than weight alone. Research conducted on 366 participants reveals that a mere 10% reduction in visceral fat can lower the risk of type 2 diabetes by an impressive 28%, regardless of overall body weight.
The health benefits are significant, including improved insulin sensitivity and reduced inflammation levels. One effective method for reducing belly fat is through the 14:10 intermittent fasting approach, where eating is limited to a 10-hour window each day.
The Yo-Yo Effect: Quick Weight Loss Isn’t Always Bad
Many people fear the dreaded yo-yo effect following rapid weight loss. However, a Norwegian study involving 284 adults challenges this perception. Presented at the Obesity Congress in Istanbul in May 2026, the findings indicated that one group consuming less than 1,000 kilocalories per day lost 14.4% of their body weight over twelve months, compared to a moderate calorie-restricted group that achieved only 10.5%. Dr. Line Kristin Johnson noted that faster weight loss did not correlate with an increased yo-yo effect.
Nonetheless, sustainable lifestyle changes remain crucial. Conditions like fatty liver can complicate weight loss, indirectly causing insulin resistance. Notably, a weight reduction of just 5% can decrease liver fat, while a reduction of 7-10% can alleviate inflammation and fibrosis.
Meal Timing: The Importance of When We Eat
Researchers from the German Institute of Human Nutrition and the Charité have examined how meal timing affects fat metabolism. Their findings showed that 1,386 genes in fat tissue adhere to a circadian rhythm.

Additionally, studies indicate that a high-fat breakfast combined with a carbohydrate-rich dinner can improve insulin sensitivity, while high-fat meals at dinner may activate inflammation-related genes.
Protein intake also plays a vital role, especially for those over 65. Dr. Chris Macdonald from the University of Cambridge recommends 1.0 grams of protein per kilogram of body weight daily to prevent muscle loss. Importantly, the source of protein matters: Animal protein correlates with a higher diabetes risk, whereas plant-based sources like legumes are considered beneficial.
Semi-Weight Loss Injections: Boon with Side Effects
The Diabetes Congress in Düsseldorf on June 25 saw around 250 experts discuss modern GLP-1 receptor agonists, which can lead to weight loss of up to 20%. However, Michael Roden from the German Diabetes Centre warns against self-treatment without medical supervision due to potential risks.
Professor Dr. Thomas Kälicke explained that these medications slow gastric emptying, which can increase anesthesia risks. Without sustainable lifestyle changes, there is a high likelihood of regaining weight after stopping the medication. Dr. Thomas Mansfeld from Asklepios West Clinic in Hamburg emphasizes that surgical interventions remain the most effective evidence-based approach for severe obesity.
Furthermore, precision diabetes care is gaining traction, with the DDZ investing approximately €70 million in a new research facility to tailor treatments more effectively. A promising approach is the DPP-4 inhibitor Trelagliptin-Succinate, which lowers the risk of hypoglycemia through a glucose-dependent mechanism with weekly administration.
Prevention: Steps We Can Take Now
Recent studies emphasize the importance of prevention. A survey during major sporting events found that approximately 14% of respondents increased their fast-food consumption during these times. The German Brain Foundation warns that highly processed foods can negatively impact the brain within days, significantly increasing the long-term risk of cardiovascular diseases, dementia, and colorectal cancer.
To engage younger populations, the Technical University of Munich launched the “Science Snack” project in June 2026, which focuses on the links between nutrition, stress, and the microbiome. Findings from the previous year’s research suggest that chronic stress can adversely affect the tumor environment in the gut.
