- 1. Fitness – The Chart - CNN.com Blogs June 4th, 2014 12:01 PM ET "Eat breakfast!" nutrition experts have been telling us for decades. It revs your metabolism! It keeps you from overindulging at lunch! It helps you lose weight! But a new study suggests the "most important meal of the day" may not be so important - at least for adults trying to lose weight. Published Wednesday in the American Journal of Clinical Nutrition, the study found dieters who skipped breakfast lost just as much weight as dieters who ate breakfast regularly. The researchers concluded that while breakfast may have several health benefits, weight loss isn't one of them. FULL POST May 20th, 2014 03:44 PM ET Approximately 18% of women are diagnosed with gestational diabetes during pregnancy - meaning they're up to seven times more likely to develop type 2 diabetes later in life. The good news is that even if you have gestational diabetes, exercise can help. A new study published this week in the journal JAMA Internal Medicine finds that every two hours of moderate activity (like walking or gardening) each week reduces a women's risk of developing type 2 diabetes by 9%. Women who added 2.5 hours or more of moderate activity to their weekly regimen reduced their risk for type 2 diabetes by 47%. FULL POST May 16th, 2014 10:29 AM ET Scientists know obese people have an increased risk of getting several types of cancer. But a new study suggests being obese also increases the chance that some patients' cancers will come back,  and increases the likelihood that those patients will die from cancer. The study was released in advance of the 2014 American Society of Clinical Oncology annual meeting, which begins on May 30. Researchers looked at 80,000 patients in 70 early breast cancer trials and analyzed their body mass index, estrogen receptor, menopause status, cancer recurrence and their prognosis.

They found for younger, pre-menopausal women who have early breast cancer, obesity appears to be strongly linked to worse outcomes, including death. FULL POST May 15th, 2014 06:01 PM ET Editor's note: This blog was originally published in June 2013 when the research was presented at the American Diabetes Association Scientific Sessions in Chicago. The final study results were published Thursday in the journal Diabetologia. You've probably heard that eating multiple small meals throughout the day is a good way to stave off hunger and keep your metabolism revved up while trying to lose weight. But a new study could change your diet strategy. Eating two large meals early and skipping dinner may lead to more weight loss than eating six smaller meals throughout the day, the study suggests. "Both experimental and human studies strongly support the positive effects of intermittent fasting," lead study author Dr. Hana Kahleova told CNN in an e-mail.

- 3. 03:33 PM ET You might want to think twice before heading out to your favorite oyster bar. According to the Centers for Disease Control and Prevention's annual report card on foodborne illnesses, vibrio infections - most frequently found in raw or undercooked shellfish - have increased by 75% since the CDC's previous analysis period, 2006-2008. That's about 6,600 cases for every 100,000 people - and for every case that is reported, the CDC estimates there 142 more that aren't diagnosed. The microbe that causes vibrio is found naturally in coastal saltwater. It only represents 1% of foodborne illness in the United States, according to the CDC, but that's still 35,000 cases of food poisoning each year. Vibrio infections are at their highest rate since the CDC started tracking nine foodborne illness-related microorganisms in 1996, according to the new report. FULL POST April 15th, 2014 04:58 PM ET Pregnant women who are obese or overweight have an increased risk of delivering a stillborn baby, according to a new study published Tuesday in the Journal of the American Medical Association. Researchers looked at 38 studies to better understand the potential risks to an unborn child in relation to its mother's body mass index. They found even a modest increase in an obese pregnant woman's weight is linked to an increased risk of fetal death, stillbirth and infant death. The highest risk was in women with a BMI over 40 (30 is considered obese). These women were two to three times more likely to experience complications. Even women with a BMI over 25 (which is considered overweight) were found to experience increased complications. FULL POST
- 4. This chart shows the trends in prevalence of overweight and obese children between 1999 and 2012. April 7th, 2014 04:01 PM ET The decline of childhood obesity rates seen in a couple of recent studies may be nothing more than an illusion, according to a new study published Monday in JAMA Pediatrics. The researchers looked at data from more than 26,000 children age 2 to 19 in the United States who participated in the National Health and Nutrition Examination Survey. They found that rates of overweight and obese children have been trending upward since 1999, with significant increases seen recently in the number of severely obese children. Severe childhood obesity rates have more than doubled since 1999, according to the study. In 1999- 2000, less than 1% of children fell into the Class 3 obesity category - meaning they had a body mass index 140% higher than their peers. In 2011-2012, 2.1% of children were in the same category. An additional 5.9% met the criteria for Class 2 obesity. FULL POST April 3rd, 2014 12:58 PM ET No, this isn't an excuse to put down your running shoes. Unless, of course, you're already running more than 20 miles a week. Research presented this week at the annual American College of Cardiology Scientific Sessions in Washington shows runners who average more than 20 miles a week don't live as long as those who run less than 20 miles a week. In fact, they live, on average, about as long as people who don't run much at all. In other words, like most things in life, moderation may be key. FULL POST March 31st, 2014 06:31 PM ET You know the saying, "An apple a day keeps the doctor away"? Turns out eating one apple isn't enough. A new study suggests people who eat up to seven servings of fruit and vegetables a day can cut their risk of premature death by 42% - and that vegetables may be more important than fruit to your overall health. The study, conducted by scientists in the United Kingdom, was published online Monday in the Journal of Epidemiology and Community Health. The study

Remember, correlation is not causation - so if a study finds a connection between two things, it doesn't mean that one causes the other. Don't diss canned vegetables American Journal of Lifestyle Medicine Researchers at Michigan State University analyzed more than 40 scientific journal studies to see if canned fruits and vegetables provide the same nutritional benefits as fresh and frozen produce. Cans are often cheaper than fresh or frozen products, and therefore easier for low-income families to buy.
