Could eating chocolate make you thinner?

Could eating chocolate make you thinner?

It's every woman's dream: could chocolate, the substance that cures everything from PMS to heartbreak,  also make you skinnier?

If true, there's got to be a catch, right?

Here's the skinny: Dr. Beatrice Golomb, associate professor of medicine at University of California, San Diego, has published a study in the Archives of Internal Medicine linking regular chocolate consumption with a lower body mass index, or BMI.

Golomb and her team surveyed 1,018 men and women aged 20 to 85 years old about their weekly food intake. Those who reported that they ate chocolate more frequently had lower BMIs. Even more surprisingly, the lower BMI group did not report eating fewer calories or exercising more than their heavier counterparts in the study.

"That does not mean that you can eat unbounded amounts of chocolate," Golomb says.

Ah, the catch.

The research is certainly intriguing. Golomb had hypothesized that the metabolic benefits of chocolate - properties that would slightly increase your metabolism - would offset the calories consumed. "I wasn’t bold enough to conjecture that the net effect would be favorable." But that's what the results showed.

Research has long revealed the heart-healthy benefits of eating small amounts of chocolate, says registered dietician Nancy Copperman, director of Public Health Initiatives at the North Shore-LIJ Health System in New York. Dark chocolate in particular is high in anti-oxidants and has anti-inflammatory properties.

A 2006 meta-analysis of studies published between 1966 and 2005 showed cocoa may even lower blood pressure, increase HDL (good cholesterol) and lower LDL (bad cholesterol). More recently in 2011, researchers at the University of Cambridge analyzed the results of seven studies and concluded that high levels of chocolate consumption might be associated with a notable reduction in the risk of developing heart disease.

Still, those cardiovascular benefits come with a risk, Copperman says. "Before you start eating a chocolate bar a day to keep the doctor away, remember that a chocolate bar can contain over 200 calories, which mostly come from saturated fats and sugar."

Dr. Susan Roberts, director of the Energy Metabolism Laboratory at the USDA Human Nutrition Research Center on Aging at Tufts University, has concerns about the way the study's researchers gathered their data. For instance, all of the participants in the study self-reported their meals.

"When I looked at this study, my first question was, 'Did they exclude people who were not accurately reporting their diet?'" Roberts wrote in an e-mail. "It is well known that people who are overweight or obese under-report their food intake, and what they under-report is the bad stuff."

In other words, the higher BMI group could have under-reported their chocolate intake. Or the lower BMI group could have over-estimated the total number of calories they were eating.

Roberts acknowledges the possible health benefits of chocolate - it contains caffeine, which may increase your metabolic rate.

"But having healthy constituents does not necessarily make the food good for weight control!" she wrote. "An example here would be cheese – it contains tons of calcium, but is not recommended as a panacea for obesity."

What's needed, all three women agree, are more studies to determine if chocolate's metabolic benefits really can offset the calories consumed, and help people keep their weight in check. Golomb would next like to do a randomized trial, which would include a control group and an experimental group. In such a trial, both groups would eat similar meal plans but only one would add chocolate to their diet.

Is there a way to ensure we're in the chocolate group? Because if so... sign us up.

      I would go with a semi-sweet 73% cacao or higher. No artificial sweeteners! An acidic PH is a prescription for a host of health problems.

      Yeah, umm, correlation and causation are different things. Perhaps you see more overweight people using artificial sweeteners BECAUSE they're fat. People of a normal weight don't usually feel a need to cut calories by using them, do they?

      Morbus is right. Regardless of whether artificial sweeteners are good or not, you're confusing correlation with causation in the same way as much of the reporting on this Chocolate study. Overweight people eat more artificial sweetener and less chocolate because they're trying to lose weight. Here's an article about this exact issue: http://simplehealth.co/chocolate-mondays-media-distortions-of-health-and-science

    I eat one or two organic 88% cocoa chocolate bites each day, too dark and not sweet enough for most people, think each one is about 50 calories and 5 grams of sugar. Good stuff.

      Absolutely right. When the medical community suggests that something is good for you I'm skeptical. The problem is that these researchers are trying to turn a complex system (the human body) into a simple one like a car. You know if you put in gasoline with a low octane rating into a car that requires higher octane you'll run into a problem. It's much more difficult to know, for instance, that increasing any nutrient will be good for you. I think the approach most likely to be helpful is "moderation in all things."

      I definitely agree with Debbie Innes suggestion on Xocai's cold pressed Belgian chocolate!

      This chocolate may or may not work for YOUR body "more2bits." I had recently met with a woman whom was allergic to chocolate from the time she was 15 years old, and was elated once she realized that within 24 hours of consuming Xocai's Healthy Chocolate, she had realized she had finally found a chocolate that she too could enjoy, and has continued to everyday since! On top of that she has created an amazing lifestyle from consuming & sharing her story.

      I would love to connect, and see if you too could share a similar story.

    I am addicted to 70-85% cocoa dark chocolate. Have been for about 5 years.
    I have a low BMI and size 4. I am slender but not anorexic looking. I don't like
    the sugar taste in milk chocolate and only eat dark. I eat very little cookies or cakes
    but prefer a couple squares of dark chocolate after dinner or before breakfast. Instead of reaching for cookies I reach for a bite of dark chocolate. One Trader Joes size bar – medium – lasts maybe 5 days.
    there is a little truth to this although my anecdote is obviously not enough to be statistically sound.

    Just like smoking. Cuban people smoke cigars daily and the average life span is early ninties...low stress, lots of coffee as well. If you eat chocolate just eat dark..anything in moderation is fine

    I also eat tons of dark choclate. I prefer the taste over milk choclate. If you want to not gain weight lay off the sugar and the carbs. Cereals is what do most people in. I still eat some carbs as I do not believe in a completely restrictive diet. But 90% of the time it is vegies, meat, nuts, eggs, dairy, and a modest amount of fruit. But I can't really say any diet helps me more then my parents absolute refusal to give me pop and candy except as an occasional treat. The lack of a sweet tooth really helps as I always stop at 3 or 4 for any sweets or just a handful of chips when I treat myself

    Weight management is best served by eating a wide variety of food in moderation, chocolate included. Those who do tend to keep weight in a normal range, hence the connection to chocolate with normal weight. The key is moderation, and it can be difficult for those who struggle with weight and often eat for reasons that have nothing to do with metabolic hunger.

    including chocolate into your diet won't make you skinnier or fatter, watching how many calories and grams of fat per day you consume is what'll do it.

    Eat fewer calories than you burn and you will get thinner, whether you eat chocolate or granola.

    Thinner doesn't mean healthier, but thin is easy to acquire if you're willing to control your caloric intake.

    Eat what you want, just do not be a lazy slob and exercise. The most important thing if you want to loose weight is that your standing metabolism + exercise (calories burned) is greater than the total number of calories you take in.

    Yes it can! Cacao is a natural, healthy food that are made not so healthy by the addition of sweeteners, fillers, etc and then they are cooked, which further reduces the nutrients.

    Proof is in the (chocolate) pudding… Interesting. I was a 2-3 x per day dark-chocolate addict. I’m a 52 year old active male at 5’8” and 150 lbs. My new year’s resolution was to stop all chocolate. Now chocolate free for 88 days with no other change in diet, I have put on 4 pounds and have my waist size has increased 1.5”. First 3 weeks was extremely challenging with mood swings, headaches and tremors (especially after meals). My goal was to reach 100 days without Chocolate, but now... Is Doctor Godiva in the house?

    This is simple....I had a bar of good organic chocolate last night (a small one) and I didn't eat dinner because I felt full. The high fat content and the serotonin release satisfied my hunger. Wasn't that why they gave chocolate bars to WWI soldiers? Maybe chocolate just makes people eat a little less than usual. Even 50 calories a day less would = big losses in the long haul.

    Bubble tea was originally created being a tea-based drink which was invented in the 1980s in tea shops in Taichung, Taiwan. As inside name, most bubble tea drinks have a tea base when combined fruit flavor or milk. Ice-blended versions are usually mixed with more ice, providing a slushy consistency. The fun of bubble tea emanates from the small chewy tapioca balls, also known as the "pearls", boba, zhen zhu, or "the chew balls".�ҹ����ء �ҹ����ء����ѹ
