For over 40 years, Charlotte Erlansson-Albertsson – professor of medical and physiological chemistry at Lund University – has been researching the importance of diet for human health and well-being. For the past 20 years, Charlotte and her team have delved into appetite regulation and energy balance.

Appetite is not just a behavior. The appetite is a biochemical and physiological regulation in the body that is largely controlled from the brain according to input from, among other things, the gastrointestinal tract.

Charlotte became interested in why much of the food we eat today easily leads to overconsumption, obesity and the complications that can result from it, and began to study these mechanisms.

Charlotte and her research team found signals that regulated how we eat protein, fat and carbohydrates while they could state that sugar and carbohydrates after the combination of fat sugar is what makes us overweight.

Our hunger signals are stronger than our satiety signals

We have strong hunger signals that motivate us to eat, preferably sweet, when we are hungry. But we have weak saturation signals. At the same time, we know that satiety means well-being. Saturation signals activate our reward system, make us happy and increase our energy consumption, which is important for our health and well-being.

Thylakoids release saturation hormones

After years of research into increasing satiety signals without increasing energy intake, Charlotte found that a natural substance in green plants, thylakoids, releases satiety hormones when ingested as food. The thylakoids are necessary for photosynthesis, ie the plants’ ability to use solar energy as an energy source, and they can now also be shown to create energy and well-being for us humans.

Appethyl® contains thylakoids

The beneficial health effects of Appethyl ® have been shown in several clinical studies at Lund University. Appethyl ® promoted weight loss, reduced waist measurements and improved metabolic parameters such as cholesterol and gluten levels. Appethyl® works in a unique triple effect: lowers appetite, delays the absorption of fats, triggers the release of satiety hormones, and prolongs the absorption of carbohydrates. The effects, use and production of thylakoids are protected by three patents.


Over the years, we have conducted many studies to ensure the effect of thylakoids on human health and well-being. These have led to the following patents.

: that thylakoids counteract obesity and obesity.

that thylakoids reduce cravings and snacking.

Prebiotic effect:
that thylakoids stimulate good bacteria in the intestinal flora.


In one of our studies, 35 women with a BMI between 25 and 33 had to limit themselves to three meals a day and exercise 30 minutes a day, for twelve weeks. Half of the group also received 5 grams of thylakoids per day. This is what the result looked like:

  • Thylakoid Group – weight loss 5 kg, be full and satisfied between meals.
  • The control group – weight loss 3.5 k, wanted to snack between meals.
