For people with coronary heart disease, losing weight will not prolong life, a new study reports, but increasing physical activity will.
To their surprise, Norwegian researchers found that in some coronary heart disease patients — those of normal weight — weight loss actually increased the risk for death.
The study, in the Journal of the American College of Cardiology, included 3,307 patients followed for an average of 16 years. There were 1,493 deaths.
Lowering body mass index by more than 0.10 in a year was associated with a 30 percent increase in the risk for death, but only in those of normal weight at the start. Weight gain was not associated with mortality.

Diet sodas may undermine weight loss efforts, a new study suggests.
Researchers put 81 overweight women with Type 2 diabetes on the same weight-control diet, except that half drank diet beverages five times a week after their main meal at lunch, while the other half substituted plain water. The study is in Diabetes, Obesity and Metabolism.
After 24 weeks, the water group had lost an average of 14 pounds, while the diet soda group lost 11.5 pounds. Average body mass index declined by 2.49 in the water group compared with 2.06 in the diet-drink group. Compared with the diet soda group, the water group also had greater improvements in fasting insulin, postprandial glucose level and other measures of diabetes severity.
Waist circumference declined in those who drank water or diet beverages, with no significant difference between the two groups.
According to the senior author, Dr. Hamid R. Farshchi, an associate professor of medicine at the University of Nottingham, the mechanism remains unclear.
But, he said, “The best drink for your health not only for weight loss but also for carbohydrate metabolism is water. Still, obese people are used to a sweet taste, and it’s very difficult for them to just say goodbye to sugary food.”

European study finds people who mostly use bikes to get around weigh less
FRIDAY, Aug. 12, 2016 (HealthDay News) -- Cyclists weigh almost 9 pounds less, on average, than people who get around mainly by car, a new study shows.
The finding from a survey that included 11,000 people in seven European cities does not prove a direct link between people's choice of transportation and weight. But researchers called the initial results intriguing.
They plan to follow 14,000 volunteers in London, Rome, Vienna and Zurich, as well as Antwerp, Belgium; Barcelona, Spain; and Orebro, Sweden. The project is called PASTA, which stands for Physical Activity Through Sustainable Transport Approaches.
"We hope this first finding will encourage more people to take part in the survey so that we can get more data over time and make a link between transport decisions and health," project leader Audrey de Nazelle said in a news release from Imperial College London. She is a lecturer at the college's Center for Environmental Policy.
Adrian Davis, a transportation and health expert in England who serves on PASTA's advisory board, noted that people who are inactive have higher odds of being overweight and developing diseases such as cancer, stroke and heart attacks.
"Our research shows that factors like urban design, how we move in cities, and the use of cars, bikes or walking could all play an important role in determining the level of people's daily physical activity," he said.
The researchers said getting people to walk or bike as part of their daily routine is an ideal way to tackle the epidemic of inactivity.
The U.S. National Heart, Lung, and Blood Institute offers a guide to physical activity.
