Taking This Supplement Daily Can Help You Lose Weight Quickly In a Week Without Dieting

[ad_1]

Resveratrol is one of the most widely studied plant compounds because of its multiple health-promoting effects. 

Some of these favorable effects include anti-inflammatory, anti-aging, anti-bacterial, anti-viral, cardioprotective, and neuroprotective (1). 

However, research in humans is limited and further research is needed to confirm these benefits.

The hype surrounding resveratrol started in 1992, with the so-called “French Paradox.” This term described a phenomenon observed in French people. 

They appeared to have lower rates of heart disease, despite eating a diet rich in fat. Scientists attributed this to the moderate consumption of red wine, which is rich in resveratrol (1).

Research is ongoing regarding the resveratrol-weight loss connection. Scientists are still trying to understand the exact mechanisms by which resveratrol carries out its beneficial effect on metabolism and weight.

There is no one magic bullet for weight loss. Successful weight loss requires a multi-pronged approach.

Exercise and a healthy diet are vital to any weight loss effort. Adding resveratrol to your diet is a tool that you can add to your toolbox that may support your weight loss efforts.

What’s Resveratrol?

Resveratrol

Resveratrol is a natural polyphenol found in over 70 plant species.

This antioxidant is produced in certain plants including grapes, apples, peanuts, soy, and blueberries. It is also found in products derived from these plant foods, such as red wine.

A major challenge for the drug industry is due to the poor solubility and bioavailability of resveratrol. 

What we do know is that there are two chemical structures of resveratrol: cis and trans. Trans-resveratrol is the more bioavailable form, which means it’s easier for the body to absorb and utilize.

Scientists are working on more effective delivery strategies to enhance the bioavailability (2). One strategy that is showing promise is direct absorption through the sublingual mucosa. In other words, absorption of the supplement under the tongue.

Calorie Restricting Effects

One theory supporting the resveratrol-weight loss link is that it has a calorie-restriction effect on the body (3, 6, 7). It is known that restricting calories can slow the rate of aging and delay the onset of numerous diseases, including obesity-related diseases. 

A study at Harvard Medical School showed that resveratrol extended the lifespan of fat mice fed a high-calorie diet. 

They also found that resveratrol reversed the negative effects of a high-calorie diet – some of which are associated with diabetes, heart disease, and other diseases related to obesity (8).

Subsequent research has been mixed and is often contradictory with regard to the soundness of using resveratrol as a calorie restricting mimetic. 

Sliming Down Effect

A review summarizing the effects of resveratrol on weight loss demonstrated that resveratrol intake significantly reduced weight, BMI, waist circumference, and fat mass, and significantly increased lean mass (9).

In animal models, resveratrol is reported to improve blood sugar control and prevent obesity (10). 

Research on the resveraterol-weight loss effect shows promise but is mixed, especially with regard to humans. 

How to Take Resveratrol

The safe window of resveratrol lies between 100 and 1,000 mg per day (4).

No adverse effects were associated in people taking 500 mg of resveratrol per day (5).

Higher does 2.5 to 5 g (2,500 to 5,000 mg) may result in mild to moderate gastrointestinal symptoms.

Pregnant or breastfeeding women should not take resveratrol.

Where to Buy Resveratrol

Resveratrol can be found in health food stores and online. Just be sure to purchase supplements through a high-quality manufacturer.

Summary

There is a wealth of promising research regarding the health-promoting effects of resveratrol. Further research is needed to confirm these benefits.

In the meantime, resveratrol appears to be safe and well-tolerated in doses up to 1,000 mg per day. As always, check-in with your doctor before adding any new drug or supplement to your diet.
