Stress and anxiety generated by cancer and supported, can lead to changes in eating behavior and overweight. Age also plays a role because with time the basic metabolism decreases and energy needs. Thus, it naturally tends to gain weight with age, which is particularly visible between 50 and 60 years. Fatigue and depression, almost inevitable in cancer, logically accompanied by a decline in untreated menopause physique.La activity (hormone treatment is cons-indicated in cases of breast cancer) and estrogen deficiency which promotes the localization of fat on the abdomen and upper body, as in hommes.Et finally, adjuvant hormonal therapies (anti-aromatase), which administered for several years after surgery, chemotherapy and / or radiotherapy, are the source of great fatigue and joint pain are not conducive to physical activity and conducive to weight gain .

Running helps you lose weight

Many people smoke to avoid getting bigger, or not to aggravate their overweight. But there is a much more effective and much less expensive method: the foot race! 

Cigarettes, and one of its active ingredients, nicotine, indeed cause a general activation of the metabolism and a rise in the total calorie expenditure, which, if your contributions are not increasing, will result in a slight loss of weight. But the race walk also activates the metabolism, even outside the calories you spend! It is estimated that 15 to 20 minutes of daily race equivalent to the effect on the weight of a pack of cigarettes.

Obesity: why do you want to lose weight?

This is true for those with cardiovascular actual risk (hypertension, cholesterol and / or triglycerides, fasting glucose greater than 1.10 g / l).However, for overweight subjects, showing no effective cardiovascular risk, weight loss or fat increases mortality, whereas weight maintenance is beneficial.

Excess mortality has been evaluated in a population of nearly 3,000 overweight or obese subjects with no cardiovascular risk. The authors divided the volunteers into groups according to their intention to lose weight and the actual weight loss achieved. They note as well as weight loss, intentional or not, has no effect on mortality at six. Thus, people who have lost weight and those who have taken have an excess mortality of 43% and 46% respectively, compared with those who maintained a stable weight. And it is precisely the subjects who intended to lose weight, but the weight remained stable, which have the lowest mortality. As for the higher mortality is observed among subjects who lost weight intentionally. And this, even compared to people who lost weight unintentionally.
