The majority of global COVID-19 deaths have been in countries where many people are obese, with coronavirus fatality rates 10 times higher in nations where at least 50% of adults are overweight, a global study found.
There is consistent evidence that higher amounts of body fat are associated with increased risks of a number of cancers (6), including:
- Endometrial cancer: Obese and overweight women are two to about four times as likely as normal-weight women to develop endometrial cancer (cancer of the lining of the uterus), and extremely obese women are about seven times as likely to develop the more common of the two main types of this cancer (7). The risk of endometrial cancer increases with increasing weight gain in adulthood, particularly among women who have never used menopausal hormone therapy (8).
- Esophageal adenocarcinoma: People who are overweight or obese are about twice as likely as normal-weight people to develop a type of esophageal cancer called esophageal adenocarcinoma, and people who are extremely obese are more than four times as likely (9).
- Gastric cardia cancer: People who are obese are nearly twice as likely as normal-weight people to develop cancer in the upper part of the stomach, that is, the part that is closest to the esophagus (10).
- Liver cancer: People who are overweight or obese are up to twice as likely as normal-weight people to develop liver cancer. The association between overweight/obesity and liver cancer is stronger in men than women (11, 12).
- Kidney cancer: People who are overweight or obese are nearly twice as likely as normal-weight people to develop renal cell cancer, the most common form of kidney cancer (13). The association of renal cell cancer with obesity is independent of its association with high blood pressure, a known risk factor for kidney cancer (14).
- Multiple myeloma: Compared with normal-weight individuals, overweight and obese individuals have a slight (10% to 20%) increase in the risk of developing multiple myeloma (15).
- Meningioma: The risk of this slow-growing brain tumor that arises in the membranes surrounding the brain and the spinal cord is increased by about 50% in people who are obese and about 20% in people who are overweight (16).
- Pancreatic cancer: People who are overweight or obese are about 1.5 times as likely to develop pancreatic cancer as normal-weight people (17).
- Colorectal cancer: People who are obese are slightly (about 30%) more likely to develop colorectal cancer than normal-weight people (18).A higher BMI is associated with increased risks of colon and rectal cancers in both men and in women, but the increases are higher in men than in women (18).
- Gallbladder cancer: Compared with normal-weight people, people who are overweight have a slight (about 20%) increase in risk of gallbladder cancer, and people who are obese have a 60% increase in risk of gallbladder cancer (19, 20). The risk increase is greater in women than men.
- Breast cancer: Many studies have shown that, in postmenopausal women, a higher BMI is associated with a modest increase in risk of breast cancer. For example, a 5-unit increase in BMI is associated with a 12% increase in risk (21). Among postmenopausal women, those who are obese have a 20% to 40% increase in risk of developing breast cancer compared with normal-weight women (22). The higher risks are seen mainly in women who have never used menopausal hormone therapy and for tumors that express hormone receptors. Obesity is also a risk factor for breast cancer in men (23).In premenopausal women, by contrast, overweight and obesity have been found to be associated with a 20% decreased risk of breast tumors that express hormone receptors (22).
- Ovarian cancer: Higher BMI is associated with a slight increase in the risk of ovarian cancer, particularly in women who have never used menopausal hormone therapy (24). For example, a 5-unit increase in BMI is associated with a 10% increase in risk among women who have never used menopausal hormone therapy (24).
- Thyroid cancer: Higher BMI (specifically, a 5-unit increase in BMI) is associated with a slight (10%) increase in the risk of thyroid cancer (25).
From The Lancet Diabetes & Endocrinology (June 2020):
Our findings show that the intensive lifestyle intervention led to significant weight loss at 12 months, and was associated with diabetes remission in over 60% of participants and normoglycaemia in over 30% of participants. The provision of this lifestyle intervention could allow a large proportion of young individuals with early diabetes to achieve improvements in key cardiometabolic outcomes, with potential long-term benefits for health and wellbeing.

From a Wall Street Journal online article:
Mr. Chambers, a 48-year-old physical therapist in Jersey City, N.J., modified his sleep, diet and exercise routines. Eighteen months later, his performance on a battery of cognitive tests improved, particularly in areas like processing speed and executive function, such as decision-making and planning.
Most surprising, says Dr. Isaacson, is that the MCI patients who followed at least 60% of their recommendations showed cognitive improvement. However, MCI patients who followed less than 60% of the recommendations experienced cognitive declines similar to the control groups, he notes.
Mr. Chambers is among 154 patients in a study, published Wednesday in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association, that doctors say shows encouraging results. Among healthy patients, people who made changes in nutrition and exercise showed cognitive improvements on average. People who were already experiencing some memory problems also showed cognitive improvement—if they followed at least 60% of the recommended changes.
From OutsideOnline.com article:
I wake up early and start my day by turning my coffee into a meal. I’ll pull three or four shots of dark-roast espresso and add one scoop of my custom-blend coconut-milk creamer, one scoop of turmeric creamer, a teaspoon of ghee or raw butter, a half-teaspoon of fair-trade red palm oil, a teaspoon of raw coconut, and a mushroom blend that includes shiitake, maitake, lion’s mane, and cordyceps. I emulsify the combination until it’s smooth and drink it before I head out to my morning surf or training session.
Midday I usually eat enough for two, because I haven’t had solid food since the evening before. I build my lunch around a serving of high-quality animal protein, like sustainable local fish or chicken. I’ll eat it on a bed of lettuce, cabbage, or kale, topped with avocado or crushed macadamia nuts and dressed with olive oil and vinegar. If it’s available, I’ll add raw-milk cheese to the salad. I try to get my carbs mostly from vegetables. When I’m in Hawaii, I’ll indulge in mashed purple sweet potatoes with coconut milk. While traveling, I do my best to enjoy what’s seasonal or indigenous to that particular location.

From a Wall Street Journal article by Heidi Mitchell:
Unlike carbohydrates or fats, proteins are the only nutrients that can be used to build new cells that can form tissue, said Dr. Walter, a registered dietitian.
“These have to be supplied by food, and the best source of them is what we call a complete protein, which includes meat, chicken, ﬁsh, milk or eggs,” she said. A total of eight ounces, or about 45 grams of protein, is all an adult needs each day, she said, and the type of complete protein it comes from doesn’t matter in a balanced diet that includes fruits, vegetables and grains.
