Different connections between weight change and overall lifestyle are studied widely. Nowadays it has become an even more widespread issue as cancer rates have been blooming. Sadly is the fact that almost anyone knows someone who has or has had this problem. It is important to draw more attention to sudden weight gain or loss which both can lead to further health concerns including cancer.
As one of the studies that bring light on consequences and importance of weight gain and loss is controlled clinical trial. It “includes a comparison (control) group.” This group receives “a placebo, another treatment, or no treatment at all.” Their experiments have proved that people can lose weight no matter what is the reason behind it as well as that decreases the risk of further complications like chronic diseases (diabetes, etc.), cardiovascular diseases and cancer. Further information is gathered from observational studies but still it is also worth to keep in mind that each case can be different as people are different. It goes beyond a simple body mass index (BMI).
As a general influence proved by studies of people with lower weight gain is that they have a lower risk of colon, breast (after menopause) and endometrial cancer. The same also works if you lose some weight as it helps to minimize the possible health problems and thus also the cancer risk.
There are numerous ways how people choose to deal with their weight. As one of the most radical ways is to undergo some surgical intervention like bariatric surgery. It can be either restriction of the food amount the stomach can hold or malabsorption of nutrients or both methods together. Despite the techniques used (laparoscopic surgery) are minimally invasive, it still often causes hormonal changes that can lead to further problems. Additionally, it involves also “gastric bypass, sleeve gastrectomy, adjustable gastric band, and biliopancreatic diversion with duodenal switch.” Yet it is still worth nothing that this radical method can be highly useful in late stages of weight loss when nothing else seems to work.
For more successful weight loss, different combinations of lifestyle and food changes can help. It might also include Diabetes Prevention Program. The main basis of it is reduced calorie consumption, low-fat diet with 1200-2000 kcal per day in a combination of 150 min of walking activity. There are also numerous other plans by specialists, including nutritionists who specialize in balanced food choices and can attribute theory into practice for each person.
It is possible to increasingly lower obesity and cancer risk with the right lifestyle choices involving at least small changes. It is worth also remembering that an effect might take a long time, but even the slightest improvement that can be firstly noticed is highly valuable for the health.
