Looking for a fruit that ticks both boxes—low in calories and helps prevent blood sugar spikes? Then berries (especially strawberries and raspberries) and grapefruit are the ideal choice.
These fruits have a low glycemic index (GI), meaning that sugar is released slowly into the body. They also contain special substances that improve insulin sensitivity.
Top picks for stable blood sugar and a slim figure
🍓 Strawberries and raspberries
Berries are unbeatable in this category.
Calories: Approx. 33 to 45 kcal per 100 g.
Why they work so well: They are rich in fiber and antioxidants (anthocyanins). Fiber slows down the digestion and absorption of carbohydrates, thus preventing a sharp rise in blood sugar after eating. Studies show that regularly eating berries improves the body’s insulin sensitivity.
🍊 Grapefruit
A traditional component of diets for weight management and metabolic regulation.
Calories: Approximately 32 to 42 kcal per 100 g.
How it works: Grapefruit has an extremely low glycemic index. It contains the antioxidant naringenin, which, according to studies, increases the insulin sensitivity of cells and helps the body process sugars from food more efficiently.
Nutritional Overview (per 100g)
Fruit Calories (approx.) Glycemic Index (GI) Main Benefit for Blood Sugar Levels
Raspberries 43 kcal 32 (very low) Extremely high in fiber
Strawberries 32 kcal 25 (very low) Rich in vitamin C and anthocyanins
Grapefruit 42 kcal 25 (very low) Naringenin increases insulin sensitivity
Blueberries 57 kcal 53 (low) Supports long-term blood sugar control
💡 Tips to get the most out of fruit:
Eat it whole, not as juice: Juicing removes valuable fiber. All that remains is the easily digestible sugar (fructose), which causes your blood sugar to spike quickly.
Combine fruit with healthy fats or proteins: Strawberries or grapefruit with a handful of almonds, walnuts, or natural yogurt will further slow the absorption of sugar into the bloodstream.
Pay attention to ripeness: The riper the fruit (e.g., bananas or pears), the higher its glycemic index. However, you don’t need to worry about this with berries and grapefruits.
