ProSilhouette® Base is an innovative program designed to help you achieve your ideal body. It is based on a bioactive citrus extract, combined with other plant extracts, vitamins, and trace elements that influence energy and fat metabolism. The result is a product program that supports fat metabolism and contributes to shaping your silhouette.
How it works

The Base Shake
The ProSilhouette® Base Shake is ideal for starting the day and can also serve as a breakfast replacement during busy mornings. It provides you with high-quality protein from chickpeas, as well as satiating fiber from psyllium husks and konjac root. The shake is enriched with extracts from pomegranate, acai, and aronia, along with lactic acid and bifidobacteria. Konjac root is particularly beneficial as it contains the plant-based fiber glucomannan, which has the highest known water-binding capacity of any natural substance and can absorb 40 times its own weight in water. This fiber swells in the stomach, helping to provide a longer-lasting feeling of fullness.
What is the yo-yo effect, and how does it happen?
What makes life difficult for us today was actually an important survival mechanism for our bodies thousands of years ago. For most of human history, long periods of hunger were not uncommon and were certainly not voluntary.
Today, however, the situation is very different: food scarcity is no longer an issue in our countries. Instead, our modern lifestyle is marked by an abundance of food and extreme physical inactivity. Inexpensive, convenient, often high-calorie, and highly processed food and treats are more popular than ever.
During a diet, the body still believes it is in a phase of hunger and slows down the metabolism to reduce energy consumption to a minimum to avoid starvation. Even after resuming 'normal' eating, the metabolism remains in 'energy-saving mode,' burning less energy to store up reserves for the next hard times.

The result: the proportion of overweight and obese children and adults is increasing worldwide at an epidemic rate. Current data from the Robert Koch Institute shows that about two-thirds of men and more than half of women in Germany are overweight, meaning they have a BMI over 25 kg/m². About a quarter of adults suffer from severe obesity (adiposity).
What is obesity?
Obesity is the medical term for morbid overweight or an abnormal or excessive accumulation of body fat. It typically occurs when the daily energy intake exceeds the body's energy needs over long periods. A rough measure of obesity is the Body Mass Index (BMI), which describes the ratio of body weight to height and can be calculated using the following formula:

However, the BMI does not provide information about the ratio of lean to fat mass in the human body. As it says very little about the health-related causes of under- or overweight, it is often criticized by experts. For example, people with a very high muscle mass are mistakenly classified as overweight or even obese according to the BMI. Therefore, experts also measure the waist-to-hip ratio. The waist circumference is divided by the hip circumference. For women, this value should not exceed 0.85, and for men, it should not exceed 1.0. A more meaningful measure is the waist-to-height ratio. This ratio provides information about body fat distribution and whether it poses an increased health risk.

Fat is not just fat
The most problematic type of fat, from a health perspective, is belly fat, also known as visceral fat, which accumulates around the internal organs in the abdomen (apple-shaped fat distribution). Visceral fat is particularly metabolically active and poses a higher risk for diseases. Hip-centered overweight (pear-shaped fat distribution), characterized by subcutaneous fat on the hips, thighs, and buttocks, is more favorable medically and is associated with fewer conditions such as high blood pressure or diabetes.

Regardless of whether the fat is on the stomach or hips, it is usually unwanted and often stubbornly resists any diet. For figure concerns, the focus is on reducing body fat in critical areas such as the abdomen, hips, waist, and thighs. This not only helps us look fitter, firmer, and healthier but also where ProSilhouette Base comes into play.
With ProSilhouette, achieve your figure goals sustainably, without hunger or the yo-yo effect
Based on the latest nutritional science, BioProphyl® has developed an innovative program that will help you achieve your ideal body. What's special about it: our program is based on a patented citrus extract, whose effectiveness has already been proven in various scientific studies.
In a 12-week double-blind, placebo-controlled study, 95 overweight participants with a BMI between 26 and 29, aged 22 to 45 years, were randomly assigned to two groups: one group received 450 mg of citrus extract twice a day, while the other received a placebo. After 12 weeks, it was found that the group receiving the citrus extract lost an average of 5.15 cm in waist circumference and 5.17 cm in hip circumference compared to the placebo group.
This patented bioactive citrus extract has been combined with other plant extracts, vitamins, and trace elements that also influence energy and fat metabolism to create the ProSilhouette program. The result is an innovative product program that supports fat metabolism and helps shape your silhouette.
