a glass of red wine a day is good for weight loss

A glass of red wine a day at lunch is good for weight loss, as it’s high in resveratrol, melatonin, polyphenols, and other phytochemicals which burn fat, control appetite, increase energy expenditure, and improve insulin sensitivity.

How many calories in a glass of wine?

A glass of wine has 125 calories. About 87% of them come from alcohol. Actually, a serving of wine (5 oz) has about 1g of sugars, 0.1g of protein, and 15g of alcohol.[1]

Alcohol has 7 calories per gram. It contains more calories per gram than carbs and protein! Carbs and protein contain only 4 calories per gram. Thus, you should avoid drinking beverages with a high alcohol content, if you’re dieting.

Moreover, you should avoid drinking wine with extra sugar, if you want to lose weight. Sweet dessert wines have 235 calories per 5 oz. Almost twice the calories of red wine!

Can wine make you fat?

Certainly, too much wine can make you gain weight, though. A glass of wine has 125 calories.

So, drinking more than a glass of wine a day makes it difficult to be in a caloric deficit. It’s absolutely vital to consume fewer calories than you burn, in order, to lose weight.

Drinking a glass of wine a day is beneficial for losing weight. More, it’s bad.

Additionally, drinking too much wine significantly affects night sleep. Bad quality sleep is linked to obesity!

Also, drinking with friends may be bad for you. We tend to drink more and consume more calories at social events. Binge-drinking can lead to binge-eating!

Therefore, you should drink only a serving (5 oz) of wine a day, if you want to lose weight. Be careful, though. As wine glasses tend to be big, it’s easy to consume more wine than you actually think.

A glass of wine a day can help you lose weight

According to many studies, drinking a glass of wine, as part of a hypocaloric diet, is beneficial for losing weight. Above all, we should limit our calorie intake from wine to 10% of the total energy consumed.[2]

It seems that moderate red wine consumption can control energy intake. It helps us consume fewer calories! Alcohol influences a number of hormones linked to satiety, such as leptin.[3,4]

Moreover, red wine seems to have a prebiotic effect. Polyphenols in red wine can positively modulate gut microbiota and increase their diversity, helping deal with obesity and other metabolic diseases.[5,6]

Moreover, according to a study among 19,220 women which last for almost 13 years, those who consumed a light amount of alcohol had a lower risk of becoming overweight or obese, as compared to nondrinkers.[7]

Another study among 15,920 women also, showed that light or moderate drinkers are less likely to gain weight over time.[8]

Resveratrol in red wine promotes weight loss

Also, wine is a good dietary source of resveratrol. Resveratrol is a polyphenol with potent antioxidant properties. High doses of resveratrol significantly decrease body weight, Body Mass Index (BMI), fat mass, and waist circumference. Also, resveratrol significantly increases lean body mass![8,9]

For instance, grapes enhance weight loss, due to their high resveratrol content. Other common foods rich in resveratrol are berries and peanuts.

Furthermore, resveratrol controls blood sugar levels and improves insulin sensitivity. Obesity is strongly associated with the development of insulin resistance and higher levels of blood sugar, which may lead to cardiovascular and metabolic diseases.[10,11]

Moreover, resveratrol may increase metabolism and decrease fat mass! Resveratrol plays a key role in the transform of white adipose tissue (fat) to brown adipose tissue, which significantly increases energy expenditure, regulates glucose and lipid metabolism.[12,13]

Melatonin in red wine is good for losing weight

Additionally, red wine is an excellent dietary source of melatonin. Merlot, Malbec, and Sangiovese cultivars are particularly high in melatonin. In fact, Merlot wine is the richest source of melatonin!

Melatonin enhances weight loss, as it seems to regulate glucose levels and appetite. Also, it may lower LDL-cholesterol and triglycerides in obese people.

Wine controls blood sugar & insulin levels

Furthermore, moderate alcohol consumption may reduce the risk of type 2 diabetes, due to improved insulin sensitivity and lower blood sugar levels.[14,15]

Besides alcohol, red wine is rich in polyphenols, which also contribute to decreased insulin resistance. In fact, red wine is considered the best alcoholic beverage for protecting your heart.[16]

We shouldn’t drink more than 1-2 glasses of wine a day, though. Too much alcohol has negative effects on glucose and insulin levels.

Obesity is strongly associated with insulin resistance, and higher blood sugar levels.

Does wine increase testosterone?

Actually, a low dose of alcohol can increase testosterone levels.[17]

On the other hand, heavy alcohol consumption results in reduced testosterone levels.[18]

High testosterone levels are associated with less body fat in the body and increased lean mass! More muscle mass means higher metabolism. Therefore, we can eat more without gaining weight.

What’s the best time of the day to drink wine to lose weight?

The best time of the day to drink wine is at lunch. A glass of wine a day is enough to promote lose weight.

Avoid drinking wine before bed, though. Alcohol helps fall asleep, but it doesn’t promote a good night’s sleep. It causes regular night awakenings, and bad sleep quality, due to snoring, or apnea.

Why should I prefer drinking red wine for weight loss, instead of white or rosé wine?

As a rule of thumb, you should prefer red wine. It has much higher concentrations of polyphenols, resveratrol, and melatonin. These compounds mainly promote weight loss.

Should I start drinking wine to lose weight?

Certainly, if you don’t already drink wine, there’s no need to start. You could eat more fruits and vegetables. They’re packted with phytonutrients which burn fat, regulate appetite, and enhance weight loss.
