Study: Prepackaged Meals May Spur More Weight Loss

By Posted on 3 Comments on Study: Prepackaged Meals May Spur More Weight Loss

With many Americans trying to get to or stay a healthy weight, it’s important to find evidence-based strategies that help people lose weight not only in the short term, but that are also realistic to follow long-term to keep the weight off. That’s important for cancer prevention, because with AICR’s latest report on stomach cancer, we now know that obesity is linked to increased risk for 11 cancers, including colorectal, endometrial and kidney.

A new study published in Obesity last week, found that in a 12-week weight loss program, people randomized to receive portion-controlled and prepackaged foods lost more weight compared to those who selected their own diet. Of the 183 participants, all overweight or obese, 139 received portion controlled, prepackaged lunch and dinner Lean Cuisine frozen entrees, and 45 selected their own foods based on the diet prescription given to both groups.

Both groups successfully lost weight, but the group receiving preportioned foods lost more than 8% (18 lbs on average ) of their weight compared to 6% (13 lbs on average) weight loss in the control group. The prepackaged meals group also had lower LDL (bad) cholesterol and triglycerides than the control group.

    Now, on World Cancer Day, We Already Have the Knowledge, Tools to Prevent So Many Cancers

    By Posted on Leave a comment on Now, on World Cancer Day, We Already Have the Knowledge, Tools to Prevent So Many Cancers

    In his State of the Union address, President Obama announced a “moonshot” program to fight cancer. In charge of that program, Vice President Biden has met with oncologists, scientists, and other leaders in the cancer field, and stated that, “We’re trying to get to a quantum leap on the path to a cure”

    Much of the focus has been on Big Data, and on sharing science across institutions, in the effort to quickly move results from the lab to the public. In a nation where approximately four in ten people can expect to be diagnosed with invasive cancer in their lifetimes, we need big efforts to fight this disease.

    Today, World Cancer Day, is a time to raise awareness of prevention: Cancer prevention needs to be a part of the renewed push against cancer.

    Focusing only on the cure is like trying to douse a forest fire on one front while someone is lighting matches on another. The good news is that we already have the knowledge and tools here on earth to prevent a large proportion of cancers from developing, without reaching for the moon.

    WCD adAvoidance of known carcinogens (including tobacco, excess radiation, sun and tanning), and use of vaccines for human papilloma and hepatitis B viruses, can prevent a wide range of cancers such as lung, skin, liver, cervix, mouth and throat. Screening and removal of premalignant lesions can prevent several cancers including those of the skin, colon, and cervix. Medications have been shown in clinical trials to prevent breast or prostate cancers in persons at high risk for those cancers.

      Sugar and Breast Cancer, An Intriguing But Early Animal Study

      By Posted on 1 Comment on Sugar and Breast Cancer, An Intriguing But Early Animal Study

      One of the most common questions we get here at AICR is about sugar. And it can be confusing. The overall body of evidence suggests that sugar’s link to cancer risk is an indirect one: diets high in sugar can lead to obesity, and excess body fat is a cause of ten different cancers.

      But now comes a study performed in mice that is getting a lot of media attention. It suggests a more direct link between sugar consumption and breast cancer development. Published in Cancer Research, the study is interesting, says AICR Vice President of Research Susan Higginbotham, PhD, RD, “but it’s important to recognize, that this is a single study and it is testing diets in mice, not in people.”

      Our reports, which have reviewed thousands of studies on diet and cancer, have found no evidence that sugar or added sugar directly causes cancer in humans. We recommend limiting energy-dense foods and avoiding sugary drinks, but current evidence suggests it is not necessary to avoid sugar altogether.”

      The animal study
      In this animal study, researchers fed groups of mice diets with increasing amounts of the sugar sucrose – your basic white table sugar – and compared them to mice fed a sugar-free starch-based diet. These mice all were carrying breast cancer cells. Read more… “Sugar and Breast Cancer, An Intriguing But Early Animal Study”
