Grapefruits have long been known as a superfood. Study results also show a clear connection between the queen of citrus fruits and a weight loss success.
Yes, they taste bitter. But there are too many good reasons not to give grapefruit a chance anyway.
These morning rituals make losing weight difficult
They are full of vitamin C, antioxidants, and minerals such as calcium and magnesium and small magic weapons for our immune system.
The cross between orange and grapefruit can do even more: As part of a study by the University of Arizona, researchers were able to find out that the fruit can also successfully help you lose weight.
Half a grapefruit already leads to weight loss.
For the study, 74 overweight adults were divided into two groups and examined over six weeks. 42 of the 72 subjects were served half a grapefruit each morning, noon, and evening in addition to the respective meal.
The 32 remaining study participants were assigned to a control group and maintained their previous diet without additional grapefruit.
After six weeks, the researchers found significant differences. The subjects’ blood pressure values improve, the researchers also found weight loss and a significant slimming of the waist.
This is how grapefruits help you lose weight.
These five properties, in particular, make grapefruit the ideal weight loss aid.
1. Hardly any calories
Due to their high water content, grapefruits at 100 grams only have 32 calories. An even lower-calorie snack is scarcely possible.
2. Vitamin C
With around 44 milligrams of vitamin C per 100 grams of pulp, grapefruit already covers more than half of an adult’s daily requirement.
This not only strengthens the immune system but also promotes fat burning. Vitamin C also produces the hormone norepinephrine, which in turn increases the body’s calorie consumption.
Pectin, a fiber, on the one hand, stimulates digestion and, on the other side, swells in the gastrointestinal tract. As a result, we feel full longer and eat less accordingly.
The contained mineral potassium has a draining effect. Excess fluids in the tissue, such as water retention, disappear better, and at the same time, toxins are removed from the body.
5. Bitter substances
Ultimately, even the bitter taste has something right: The bitter substance naringenin influences specific proteins in such a way that the liver prefers to break down fatty acids.
