CHAPTER 14: D IS FOR DIABESITY: REVERSE THE EPIDEMIC THAT’S DESTROYING BRAINS, MINDS, AND BODIES
As your weight goes up, the size and function of your brain go down.[585]
CYRUS RAJI, MD, PHD, ASSISTANT PROFESSOR OF RADIOLOGY, WASHINGTON UNIVERSITY
My wife and I saw you on Facebook and decided to give your program a try. We knew we had to make some changes for our family. My wife has Hashimoto’s disease [neurohormones]. My daughter has polycystic ovarian syndrome [neurohormones] and struggled with moodiness, and I had not felt great about myself in a long time.
We made a commitment as a family to do what you said and give it two weeks. If it hadn’t been for my wife pushing us, I would have quit. I admit we struggled with cravings for the first few days. After one week the cravings were gone! In fact, real food started to taste delicious. I was surprised how much the flavor was magnified in a carrot. I never noticed before. After two weeks on the program, we couldn’t have been happier. We all felt fantastic and had each lost between 10 and 12 pounds [diabesity] and no longer thought about quitting. Each week on the program gets better and better, and we feel more energetic [blood flow] than ever! In fact, I can’t remember the last time I have ever felt this wonderful. I lost 20 pounds after four weeks. People tell me that my skin looks great. I am more confident, more energetic, and I sleep so much better.
Now we are all mentoring our family and friends to live this way. Both my wife and daughter had struggled with weight loss in the past in spite of exercising twice a day at times. My wife has lost 24 pounds since she started eating this way, and her skin is also more vibrant. My 18-year-old daughter has lost 22 pounds and feels happier and much more confident. As soon as they started eating according to your food rules, they were able to exercise a fraction of the time and get more results. What you eat matters!
One of the amazing things we’ve noticed is how many other people ask us for help after seeing our family’s transformation. My mother, who lives with us after suffering several strokes [blood flow], is now eating this way. Her moods and energy are much better. She is more social and no longer isolates herself to her room as much. My mother-in-law, who suffers from fibromyalgia [immunity/infection], also reports less pain and is able to walk more easily. Even our two younger sons, who don’t seem to have much interest in learning about our new lifestyle yet, are eating better without even realizing it because we no longer have junk food in the house. We know this will have a long-term effect on their health. As a family we are healthier and happier.
Several of my coworkers noticed the changes and have started the program. Now they are asking me a ton of questions. When you feel good, you look better. I even walk differently, and I think people notice. It’s hard not to share what you learn when the changes are so obvious.

Diabesity is having high blood sugar and/or being overweight or obese. In the United States, it has become an epidemic that continues to get worse, with half the population affected by prediabetes (36 percent) or diabetes (14 percent),[586] 70 percent considered overweight, and 40 percent falling into the obese category. The annual medical costs of obesity alone top more than $150 billion.[587] Diabesity is destroying brains, minds, and bodies, and it’s robbing our children and grandchildren of their future. They will not be able to afford the tsunami of illness that is headed their way unless we get serious and do something about it. The increase in diabesity is one of the main reasons brain health/mental health issues are increasing. Both high blood sugar and being overweight take a toll on the brain and mind and negatively impact the BRIGHT MINDS risk factors.
Excess fat on your body is not your friend. Obesity is detrimental to brain health/mental health and is associated with a greater risk of depression, bipolar disorder, panic disorder, agoraphobia (fear of going out), and addictions.[588] Untreated attention deficit disorder/attention deficit hyperactivity disorder (ADD/ADHD),[589] lower self-esteem, and poor body image[590] are also associated with being overweight.[591] Among women, increased body mass index (BMI) is also linked to a rise in suicidal thoughts.[592] Being overweight or obese also impacts your BRIGHT MINDS risk factors. For example, it has been associated with a smaller brain and decreased blood flow to the brain.[593] It produces chemicals that increase inflammation, store toxins, and disrupt hormonal function. It also makes you more susceptible to developing sleep problems, such as sleep apnea.[594]
High blood sugar is associated with a smaller hippocampus, the seahorse-shaped structure in your temporal lobes associated with mood, learning, and memory. Anxiety and depression are two to three times higher in patients with Type 2 diabetes than in the general population.[595] High blood sugar causes blood vessels to become brittle and break, delays healing, increases the risk of stroke, and causes overall lower blood flow in the brain. In fact, diabetes has been linked to decreased blood flow on SPECT scans.[596] On top of that, high blood sugar and diabetes are also associated with increased inflammation; Alzheimer’s disease; strokes, heart disease, hypertension; and accelerated aging.[597] People with diabetes are also at greater risk for eating disorders, such as binge eating.[598] Having diabetes during pregnancy significantly increases the risk of psychosis in the children (auditory and visual hallucinations).[599]
All of the four circles play a role in the diabesity connection to brain health/mental health:
By the way that our culture promotes unhealthy food choices and indulgence, you would think an evil ruler has gotten a hold of us and is behind all our weight issues and the diabetes epidemic.
THE EVIL RULER WOULD . . .
- 1. Demand that high-sugar desserts be served with all school lunches as a way to boost inattention among children.
- 2. Encourage companies to put out candy bowls and doughnuts in the break room to raise the risk of diabesity.
- 3. Fool people into viewing sweet desserts (which spike blood sugar and contribute to anxiety and other mental health symptoms) as a “reward” for good behavior or a job well done.
- 4. Allow unhealthy, artificially flavor-enhanced foods and drinks to be aggressively marketed as desirable (think Coke’s “Open Happiness” slogan). In fact, the evil ruler would encourage professional athletes and coaches to visibly drink Coke, Pepsi, or Gatorade (all filled with sugar, artificial colors, and preservatives) on the sidelines of games as a way of marketing these products to children and teens.
- 5. Tell people that diabetes isn’t that bad and discourage making any lifestyle changes because there are drugs they can take for it.
- 6. Blame genetics for the obesity epidemic, saying there’s nothing people can do about it.
THE BENEVOLENT RULER WOULD . . .
- 1. Limit sugar-laden snacks and desserts in school lunches to promote stable blood sugar levels and healthy weight.
- 2. Encourage corporations to serve brain-healthy snacks to employees to prevent diabesity.
- 3. Tell the truth that drinking and eating foods that make you fat and diabetic is not a smart way to celebrate.
- 4. Prevent food and beverage manufacturers from easily marketing products that increase the risk for diabesity.
- 5. Educate people about the consequences of diabetes and encourage lifestyle changes —exercise and diet —to regulate blood sugar levels.
- 6. Inform people that their DNA is not their destiny. Their daily habits can influence their genes, and it is within their power to control their weight.
As your weight goes up, the size and function of the brain goes down; which should scare the fat off everyone.
INSULIN AND THE BLOOD SUGAR-MOOD CONNECTION
In chapter 14, you learned about six of the neurohormones that influence your brain health/mental health. Here, I’ll show you how the seventh neurohormone, insulin, is related to diabesity and your mental well-being. In the body, the hormone insulin is involved in regulating blood sugar levels. Your body’s cells need sugar (glucose) for energy, but they can’t absorb it directly from your bloodstream. That’s where insulin comes in. Released by the pancreas when you eat carbohydrates, insulin is like a key that unlocks cell membranes so they can get the glucose they need from the foods you eat.
Now, not all carbohydrates are created equal. Complex carbohydrates (such as vegetables, quinoa, and fruits) help keep insulin working effectively and stabilize blood sugar levels. However, simple sugars (such as cookies, candies, and sodas) as well as highly processed carbohydrates (such as bread, pasta, and crackers) require the pancreas to pump out large amounts of insulin and can cause blood sugar levels to soar. If there’s too much sugar in your bloodstream, insulin signals your body to shuttle it to the liver for storage, which can eventually lead to fatty liver disease in some people. Another consequence of high insulin levels is that the body switches from breaking down and flushing dietary fat from the body to storing that fat, which over time can lead to weight problems. One of the main consequences of chronically eating a high-sugar diet and being obese is a decrease in insulin’s ability to regulate blood sugar, leading to prediabetes and diabetes.
How do insulin and blood sugar levels affect your mind? Eating sugar or refined carbs causes blood sugar levels to spike and, subsequently, causes them to crash. This roller-coaster effect can impact your moods and mental well-being. Research shows that high-sugar diets and blood sugar issues are associated with:
- Anxiety[600]
- Depression[601]
- Schizophrenia[602]
- Irritability[603]
- Anger[604]
- Addiction to sugar[605]
- Trouble concentrating[606]
If you want to get your brain right, it is imperative to get your food right. Eliminating sugar and other refined carbohydrates from your diet can help regulate your body’s production of insulin, stabilize blood sugar levels, and facilitate the fat breakdown process. It can also prevent the depletion of chromium, a mineral required by insulin receptors. In a fascinating study,[607] researchers from the University of Illinois looked at the nutrient levels of patients and compared them to scans of their brains and measurements of executive function (planning and impulse control) and intelligence. Improved executive function was associated with higher levels of omega-3 fatty acids, lycopene, carotenoids, vitamin D, and vitamins B2 (riboflavin), B9 (folate), and B12 (cobalamin). The brain functioned better with higher levels of omega-3s and carotene; and omega-3 levels were associated with higher intelligence.
Eliminating sugar and other refined carbohydrates from your diet can help regulate your body’s production of insulin, stabilize blood sugar levels, and facilitate the fat breakdown process.
