Body Weight Copy

Having a healthy body weight is linked to lower risk of many types of cancer, better body terrain—a body that is less supportive of cancer—fewer or less severe side effects and symptoms, and in some cases better survival after diagnosis.

A letter from Laura

Sometimes I fear that people who struggle with too much weight may not want to hear from me—I’ve never been worrisomely overweight—they’ll just say I don’t understand what it’s like. Well, it’s true that I don’t know what it is to live in a body that is overweight, but it’s also true that I’ve never had cancer, yet I’ve been able to be of true service to many who have cancer. So, here goes.

The sections below this letter will tell you about what the science tells us about the very real and significant effects of body weight not only on general well-being but also on cancer risk and how people with cancer tend to fare. And, we’re not just talking about problems with being overweight, but being at an unhealthy low weight, as well. I have to be honest, the research is still evolving about this, and some of the information is confusing. We don’t always have good explanations and therefore aren’t always certain what advice to give. But there are many pieces of the weight puzzle that we do understand and for which we have good advice.

Giving simple, good advice about weight is sometimes muddied by all the other messages bombarding us. The picture of health and what is desirable in a body has been painted by commercialism—not by we, the artists creating our own body-mind-spirit. The ads and our celebrity icons show us that “skinny is good”, while at the same time telling us to eat and drink more and more of the things that pull us away from those unattainable ideals, and more importantly from simply being healthy. Then, there are the slews of diet books and websites and health gurus with promises of making a new you in no time, often without any consideration of underlying health issues or your specific metabolism and relationship to food.

We don’t provide a diet prescription for you in these pages, but we do present some down-to-earth facts about the importance of weight in cancer treatment, recovery and survival. We also give you some general ideas on a basic health-supportive approach to managing weight as well as resources for where to go from here.

We care that you find all the support and guidance you need to find your healthy weight—the weight that will reflect the inner energy and vitality to carry you forward without “weighing” you down in your walk through the cancer experience.

Take care,

Laura

Healthy body weight at a glance

Having a healthy body weight is linked to lower risk of many types of cancer—at least 13 cancer types have known links to obesity. Obesity is linked to body terrainthe internal conditions of your body, including nutritional status, fitness, blood sugar balance, hormone balance, inflammation, and more factors that are known to support cancer development and growth, including high blood sugar and insulin resistance, hormone imbalances, immune function, inflammation, oxidative stress, and microbiome imbalances. A healthy body weight is linked to fewer or less severe side effects and symptoms, and in some cases better survival after diagnosis.

What’s a healthy body weight for you?

To measure whether or not body weight may be a concern for you, measuring your Body Mass Index can be a useful tool. Body mass index (BMI) compares your weight to your height; it is calculated as kilograms per meter squared (kg/m²). Most of the research we cite defines overweight as a BMI between 25 and 29.9, and obesity as a BMI of 30 or higher. Underweight is a BMI lower than 18.5. Like the researchers we cite, we realize that BMI is not a perfect measure of overweight or obesity, as it doesn’t differentiate between lean body mass and excess body fat. But a BMI between 18.5 and 24.9 is a good indicator of healthy body weight for most people.
