To Lose Weight or Not to Lose Weight, That Is the Big Question—in Obesity-Related Heart Failure

Obesity and heart failure (HF) are twin public health problems. Moreover, obesity can contribute to HF (1). Each contributes to increased mortality. Conversely, weight loss in obese patients without HF improves diastolic function and decreases oxygen requirements and left ventricular (LV) mass (2,3). In two large studies, surgery-induced weight loss reduced cardiac death and improved survival i...

Reducing Calorie Intake May Not Help You Lose Body Weight

As the widespread availability of highly calorific food has resulted in a high incidence of obesity, attempts to decrease body weight have concentrated on trying to reduce energy intake. It is suggested that this is not the best approach. Although consuming more calories than expended is part of the initial problem, it does not follow that reducing intake, unless consciously counting calories, ...

To Weight or Not to Weight: Where is the Question?

We investigate the approximability properties of several weighted problems, by comparing them with the respective unweighted problems. For an appropriate (and very general) deenition of niceness, we show that if a nice weighted problem is hard to approximate within r, then its polynomially bounded weighted version is hard to approximate within r ? o(1). Then we turn our attention to speciic pro...
