What do you think is a moderate amount of pizza? I would say 1-2 slices, but I can bet that my 20-year-old brother would say the whole pizza. Eating food in moderation has become a common piece of advice for weight-maintenance and weight-loss. Being a healthy weight is the most important thing you can do to prevent cancer, after not smoking, according to AICR research.
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.
Losing weight is hard. Keeping it off is harder. It’s definitely doable — we’ve written about successes here — but wouldn’t it be great if young adults could prevent gaining too much weight in the first place? A new multi-year study suggests that with daily weigh-ins and a few small changes, you can.
The study is among a growing area of research looking at ways to prevent weight gain, and it’s one of the largest randomized controlled studies on the topic to date. Previous research cited in the study suggests that young adults gain about 1.5 pounds per year. Over a couple decades, that adds up. And with two-thirds of US adults now overweight or obese, the research carries important potential for slowing the obesity epidemic. That, in turn, will play a role in cancer prevention. AICR research shows that carrying too much body fat is a cause of 11 cancers, including postmenopausal breast, ovarian and advanced prostate.
This study built upon prior research about how knowing and tracking your own weight can help with weight control.
