Are Dark Chocolates high in sugar?
Dark chocolates contain about 24.2g sugar per 100g — mostly natural sugars when whole.
Is dark chocolate good for weight loss?
Yes, dark chocolate can support weight loss when integrated mindfully. Its rich flavor and high fiber content (10.9g per 100g) help satisfy cravings with a smaller portion, preventing overeating. However, because it contains 598 kcal per 100g, strict portion control is essential to maintain a calorie deficit.
Is dark chocolate keto-friendly?
With net carbs sitting at approximately 35.0g per 100g, dark chocolate is generally too high in carbohydrates for a standard ketogenic diet in large quantities. However, a very small portion (such as 10g to 15g of 85% or 90% dark chocolate) can fit into some daily keto carb allocations.
What is the glycemic index of dark chocolate?
The estimated glycemic index of dark chocolate is 23, which is considered low. The high concentration of healthy fats (42.63g) and dietary fiber (10.9g) slows down the digestion and absorption of carbohydrates, resulting in a stable, gradual release of glucose into the bloodstream.
Is dark chocolate safe for people with diabetes?
Yes, dark chocolate is generally safe for people with diabetes when consumed in moderation. Its low glycemic index of 23 means it won't cause rapid blood sugar spikes. However, because it contains 24.23g of sugar per 100g, it should be paired with protein or healthy fats to further stabilize glucose.
How many calories does dark chocolate have?
Dark chocolate contains approximately 598 calories (kcal) per 100g, according to USDA reference data. A standard 1-ounce (28g) serving provides about 170 calories. This calorie density means that while it is highly nutritious, portion control is key to keeping your daily energy intake balanced.
