Can drinking cranberry juice at night make you gain weight?

Cranberry juice is mainly water and sugars. In fact, 87% of its calories come from sugars. Cranberry juice has 50 calories per 100g, or 100 calories per serving (1 juice box, or 200 mL).[1]

As a rule of thumb, you should avoid drinking fruit juices, though. Most of them are packed with sugars. Even moderate amounts of homemade, fresh-squeezed fruit juices can make you gain weight.

High intake of sugar is a common reason for increased rates of obesity in the United States. Nowadays, we consume about 300% more sugar than the upper recommended dose.[2]

Above all, fruit juices don’t reduce hunger, as they lack of dietary fiber. Fiber takes a lot of space in the stomach, sending satiating signals to the brain. On the contrary, whole foods are high in fiber. Prefer them, instead of drinking their juice. Especially, if you want to lose weight.

High daily intake of fiber significantly lowers the risk of obesity. We should get 28g of fiber per 2,000 calories. Unfortunately, most people who follow the standard Western diet consume fewer than 20g of fiber a day.[3]

Actually, a serving of cranberry juice contains about 23g of sugars and no fiber.

Moreover, fiber prevents the spikes of blood sugar! The Glycemic Index of food shows how much it affects blood sugar. The lower, the better. For instance, cranberry juice has a moderate Glycemic Index of up to 68.[4]

As a rule of thumb, you should prefer eating foods with a low Glycemic Index. They help maintain a healthy body weight, as they minimize insulin responses, maintain insulin sensitivity, control appetite, and promote fat burn.[5]

Therefore, if you want to lose weight, you better consume whole cranberries at dinner. They won’t spike your blood sugar levels as much, and also, you’ll feel full, consuming fewer calories. After all, caloric deficit is crucial for weight loss.

Moreover, you could drink a glass of cranberry juice, along with a low-calorie meal, such as a salad, in order to lose weight. Fiber from vegetables will delay the absorption of sugars of the juice in the bloodstream.

Drinking cranberry juice before bed can help you sleep better at night

Most noteworthy, the best time to drink cranberry juice is before bed. It could help you sleep better at night, due to its extremely high amount of melatonin!

Melatonin is known as “the sleep hormone”. It’s the internal clock of the body. Cranberry juice contains extraordinary amounts of melatonin. It has up to 960 mcg of melatonin per 100g!

Besides the improvement on sleep duration and quality, melatonin promotes weight loss, protects from oxidative stress, boosts the immune system, and protects the heart.

Drink cranberry juice to boost your daily intake of vitamin C

Moreover, you could drink orange or grapefruit juice to instantly get the recommended daily intake of vitamin C.

Potassium neutralizes sodium. Sodium comes mainly from salt. Therefore, it’s good to get enough potassium when you eat foods high in salt. The main sources of salt in the modern Western diet are processed products and fast food.

So, as a rule of thumb, try to eat at least 5 servings of fruits and vegetables a day. They’re the richest foods in potassium.[8]

A serving (200 mL) of cranberry juice has up to 46 mg proanthocyanidins, 26 mg anthocyanins, 12.8 mg hydroxybenzoic acids, 3.8 mg, hydroxycinnamic acids, and 11.6 mg flavonols.

Due to its exceptional antioxidant content, besides weight loss, cranberry juice has many health benefits.

For instance, regular drinking of cranberry juice may lower LDL (“bad”) cholesterol, lower total cholesterol, increase (“good”) HDL cholesterol, improve endothelial function, lower the risk of coronary heart disease, lower glycemic responses, have favorable effects on blood pressure, and protect against urinary tract infections.[9]

In fact, polyphenols in cranberry juice have potent antibacterial, antiviral, antimutagenic, anticarcinogenic, anti-inflammatory, and antioxidant properties!
