Grapefruit juice is packted with vitamin C, potassium, and health-promoting antioxidants, such as flavonoids. But, the best time to drink it for weight loss is in the morning, not before bed, due to its high sugar content.
Don’t drink grapefruit juice before bed
Above all, you shouldn’t drink grapefruit juice before bed because it’s pretty high in sugars. In fact, about 94% of its calories come from sugars! A 12 oz glass of grapefruit juice has about 30g of sugars.
As grapefruit juice has no fiber, it has a much higher Glycemic Index than whole grapefruit. Whole grapefruit has a Glycemic Index of 25, while grapefruit juice has a Glycemic Index up to 60.
Therefore, even fresh-squeezed, homemade grapefruit juice can spike your blood sugar levels.
High intake of sugar is a common reason for increased rates of obesity in the United States, and other developed countries. Most people consume much higher amounts of sugar than the recommended dose.
Our bodies need sugar for energy. But, we consume much more than we actually need.
What’s the best time to drink grapefruit juice?
Furthermore, the human body is more efficient in metabolizing sugar during the daytime. It converts most of it to muscle glycogen. Practically, the best time to drink grapefruit juice is in the morning. Drinking a glass of grapefruit juice at breakfast won’t make you gain weight.
On the contrary, the body converts most consumed sugar to body fat at night. So, drinking a beverage rich in sugar, such as grapefruit juice before bed, may cause weight gain.
Moreover, excessive doses of sugar at night may negatively affect sleep duration, and sleep quality. Additionally, less sleep has been linked to increased appetite, increased risk of obesity, fatigue and poor physical performance.[4,5,6]
Hence, the worst time to drink grapefruit juice is before bed. You should avoid all sugary beverages as well. For instance, soft drinks, energy drinks, sport drinks, and even fruit juices all contain high amounts of sugars.
Also, a great time to drink grapefruit juice, without gaining weight, is before or after exercise.
First, the body will burn the sugar of grapefruit juice for energy during a workout. Moreover, getting sugar after exercise helps replenish glycogen stores in the muscle. This is crucial for faster muscle recovery! Also, grapefruit juice could be the main ingredient of your post-workout smoothie.
Grapefruit juice at night won’t reduce hunger
Another reason why you shouldn’t drink grapefruit juice at night is because it can’t reduce hunger!
Grapefruit juice, as all juices, lacks of fiber. Dietary fiber delays digestions and expands in the stomach, sending satiating signals to the brain. So, we consume fewer calories in a day. Most importantly, without feeling hungry all the time!
Actually, a diet high in fiber aids weight loss, and significantly reduce the risk of obesity. We should consume about 28g of fiber per 2,000 calories.
Hence, prefer consuming whole grapefruit, instead of grapefruit juice. In fact, a whole grapefruit has about 2.7g of fiber and only 75 calories. Therefore, whole grapefruit is good for losing weight.
What’s the best time to drink the Vitamin C-rich grapefruit juice?
Moreover, grapefruit juice has many health benefits, due to its high vitamin C content.
An 12 oz glass of grapefruit juice has about 130 mg of vitamin C, or 140% of the recommended daily intake!
Along with orange juice, they are among the richest common sources of vitamin C.
Additionally, vitamin C may help you sleep better at night. Adequate amounts of vitamin C can increase sleep duration, reduce sleep disturbances, relieve movement disorders, and decrease the dangerous effects of sleep apnea. Also, vitamin C may improve stress tolerance.[8,9]
But, there is no need to get vitamin C right before bedtime. You can consume foods containing vitamin C throughout the day.
Potassium in grapefruit juice aids weight loss!
Also, grapefruit juice is pretty high in potassium. A 12 oz glass has about 550 mg of potassium, or 16% Daily Value.
A diet high in potassium promotes a low Body Weight Index (BMI), small waist circumference, and lower risk of obesity!
Another good time to drink grapefruit juice is with a meal high in salt. Potassium neutralizes the negative effects of sodium. On the contrary, consuming too little potassium and too much sodium can increase your risk of heart disease and stroke.
Most people fail to consume the recommended daily dose of potassium, though. The potassium deficiency is pretty common among people who follow the standard Western diet.
Try to eat at least 5 servings of fruits and vegetables a day to increase your daily potassium intake.
Grapefruit juice is packted with flavonoids which enhance weight loss
Most noteworthy, grapefruit juice is an excellent source of flavonoids. Its flavonoid concentrations are up to 84 mg per 100 ml.
Furthermore, besides obesity, flavonoids are beneficial against other metabolic disorders, such as type 2 diabetes! They can improve insulin sensitivity, prevent the buildup of new fat tissue, fight inflammation, and even increase metabolism.
What’s the best beverage to drink before bed?
The best beverage to drink before bed is chamomile tea. It’s packted with antioxidants, relieves from stress or anxiety, and helps sleep better at night. You can add lemon juice to your chamomile tea to further boost your vitamin C and total antioxidant intake.
Moreover, you should consume foods high in melatonin before bed. Melatonin helps you sleep better at night.
Last, but not least, grapefruit juice has been found to interact with several medications. It increases their oral bioavailability. Hence, the risk of toxicity. Therefore, if you take any medicine, you should consult your health care provider before drinking grapefruit juice.
