Modern nutritional counseling no longer relies on strict prohibitions but focuses on physiological principles and psychological flexibility. The combination of a moderate calorie deficit, targeted nutrient composition, and physical activity is considered the foundation for sustainable weight reduction.
The Three-Rule Model
Experts have identified three core rules that assist in weight loss without having to forgo specific foods.
Rule 1: Combine every meal with proteins and fibers. This promotes satiety.
Rule 2: Maintain a moderate calorie deficit of 300 to 500 calories per day. This ensures enough energy for metabolism while the body taps into fat reserves.
Rule 3: Apply the 80/20 rule. 80 percent of the diet should consist of nutrient-rich foods, while 20 percent is reserved for enjoyment without guilt.
Ideally, these principles should be complemented by more movement in daily life and two to three training sessions per week.
The Blood Sugar Trick – And Its Limitations
A widely discussed approach is the glucose diet, which emphasizes the order of food intake: first, fibers; then fats and proteins; finally carbohydrates and sugars. This is believed to prevent blood sugar spikes.
Scientific evidence? Still lacking, experts admit. The effects vary significantly among individuals.
Hidden Fat Accelerates Aging
Medical studies underline the importance of fat distribution. A study published in the journal Obesity shows that visceral fat – the fat tissue around internal organs – can accelerate cellular aging. For every 100 grams of visceral fat, biological age increases by 0.32 years in women and 0.16 years in men.
Moreover, this type of fat tissue promotes chronic inflammation and heightens the risk for Type 2 diabetes as well as cardiovascular diseases.
Chronic inflammation and fluctuating blood sugar levels are often tightly connected to our daily food choices.
Medications as Support
In addition to conventional methods, pharmaceutical therapies are gaining significance. Claudia Effenberg has been using the medication Mounjaro under medical supervision since March 2026 for weight loss after health setbacks.
In clinical research, new active substances are emerging: oral semaglutide enabled weight loss of up to 17 percent in studies. A so-called triple agonist (BI 3034701) is currently in Phase II clinical trials.
However, doctors warn of side effects, such as an increased risk of hair loss with GLP-1 agonists. In Austria, where more than a third of adults are overweight and around 16 percent are classified as obese, addiction specialists also suggest examining eating behavior from a neurobiological perspective to prevent relapses.
Three Success Stories – Three Strategies
Practical evidence shows that different paths lead to the same goal.
Aline lost 100 kilograms in one year – without surgery or medication. Kerstin relied on conscious eating, adequate sleep, and movement, resulting in a loss of 13.6 kilograms in twelve weeks.
31-year-old Jared halved his body fat percentage in ten months by increasing his protein intake and focusing on complex carbohydrates.
It’s important to note that sugary drinks can reduce fat burning by up to one-third during protein-rich meals, according to the USDA. Avoiding sodas and energy drinks can optimize metabolism.
