Fighting a Fatty Liver

A couple of years ago my doctor asked me how much alcohol I was drinking because my blood test came back with abnormal results.  I don’t drink very much or very often so i was surprised by the question.  It turns out that the most common disease in America is called NALFD (non-alcoholic fatty liver disease) or fatty liver, for short, and is a major risk factor for diabetes, heart attacks, and even cancer. It can progress to Non Alcoholic Steatohepatis (NASH), which causes liver inflammation and can lead to cirrhosis or liver cancer in about 10% of those affected.

Fat and the liver: Though the exact effect of excess fat on the liver isn’t well understood, it appears to create problems on a spectrum. At the low and least harmful end, the liver may be able to perform its many functions even while it contains too much fat. However, once inflammation and swelling occur in the organ, scarring can result as the liver tries to heal itself. This is a hallmark symptom of liver injury in advanced non-alcoholic fatty liver disease: collagen is laid down, and fibrosis or thickening of the liver tissue ensues. As the disease progresses, about 10% of cases will develop over the next ten years into the much more serious NASH, or non-alcoholic steatohepatitis. NASH can lead to cirrhosis or hardening of the liver, liver failure, liver cancer, and death.

What causes it?  The high fructose corn syrup found in our processed foods is the single biggest cause of fatty liver. Soda, which, frighteningly, is the number one source of calories in the American diet, is the biggest cause of fatty liver.

Who gets non-alcoholic fatty liver disease? Though the exact causes of NAFLD are not known, most of the people who develop it are obese, have type 2 diabetes or have metabolic syndrome, which is associated with insulin resistance. What’s more, the severity of NAFLD increases with the degree of obesity, and abdominal or belly fat seems to increase the risk of dangerous NASH, even in patients with a body mass index (BMI) in a normal range.

Genetic factors influence each individual component of the syndrome, and the syndrome itself. A family history that includes type 2 diabetes, hypertension, and early heart disease greatly increases the chance that an individual will develop the metabolic syndrome.

Environmental issues such as low activity level, sedentary lifestyle, and progressive weight gain also contribute significantly to the risk of developing the metabolic syndrome.

Metabolic syndrome is present in about 5% of people with normal body weight, 22% of those who are overweight and 60% of those considered obese. Adults who continue to gain five or more pounds per year raise their risk of developing metabolic syndrome by up to 45%.

While obesity itself is likely the greatest risk factor, others factors of concern include:

  • Women who are post-menopausal
  • Smoking
  • Eating an excessively high carbohydrate diet
  • Lack of activity (even without weight change)

How do you know if you have it?

There are blood tests available that can detect a fatty liver. You can also see it on an ultrasound. And if your test comes back abnormal, you are in trouble. But even if your test comes back normal, you might not be out of the woods. It’s important to know that a liver function test doesn’t always detect a fatty liver. An ultrasound can be more sensitive.

The bottom line is, if you eat a lot of sugar and flour, if you have a little bit of belly fat, or if you crave carbs, starch, and sugar, you probably have this.

How to fix your fatty liver

The most promising treatments for NAFLD are weight loss (including bariatric surgery) and exercise. There are some really simple things you can do:

  • Cut out all high fructose corn syrup from your diet. If you see it on any label for any product—whether it’s a salad dressing or ketchup or tomato sauce—don’t eat it.
  • Reduce or eliminate starch. Get rid of white, processed flour. Even whole grain flours can be a problem.
  • Add some good things to your diet to help heal your fatty liver. Add plenty of fruit, vegetables, nuts, and seeds. Add lean animal protein like chicken and fish. Add good oils like olive oil, macadamia nut oil, avocados, coconut butter, and fish oil. Good fats like these are anti-inflammatory, and they help repair your liver.
  • Improve your metabolism through exercise. This is a fabulous way to improve insulin resistance and reduce fatty liver.
  • Supplements:  Polyunsaturated Fatty Acids (PUFA’s), can be helpful. Omega 3 fish oils have been shown to reduce fatty infiltration on ultrasound, and they’re also anti-inflammatory and reduce insulin resistance. A recent study used Cinnamon (1500mg) to treat NALFD and found that liver enzymes improved (as well as blood sugar, lipids and inflammation markers).

Healthy Eating and Walking

So the thought for today is to eat better and continue exercising.  It’s a lovely day so I did a 3.7 mile loop of the park this afternoon.  As for healthy eating, I like the advice of: Prospect Park Preserve

  • cutting out junk food, processed foods, sugars…[including the dreaded High Fructose Corn Syrup]
  • eating more colorful and fresh foods
  • eating in moderation [drinking more water as I might be thirsty rather than hungry]

I found a nice web page called Healthy Eating Easy Tips for Planning a Healthy Diet and Sticking To It from Helpguide.com that provides some common sense advice.

I had a weird diet day today.  I slept in this morning so ate fewer meals.  I’m not sure how that ranks in the BMR [Basal Metabolic Rate] calculation.  Given my 3-5 days/week of moderate exercise activity, I can eat about 2150 calories each day.  The Fat2FitRadio.com calculation is described as:

The chart shows the number of calories that you should eat on a daily basis to reach your goal weight. At Fat 2 Fit Radio we advocate eating like the thin, healthy person that you want to become. The calorie levels …create that all important caloric deficit that is required to get you to your goal weight in a safe manner. Once you reach your goal weight, you will continue eating the same number of calories for the rest of your life to maintain that weight. You’ll never be on a diet again.

Based on how much activity you do on an average day, the [calculation provides] the number of calories that you will be able to eat at your goal weight. If you start eating those calories right now (eating like the thinner you), you will eventually become that thinner person.

Given that I woke up late today, I only ate 2 meals and consumed approximately 650  calories today….. is that bad? I don’t know….

Optimum Nutrition - 100% Nat Oats & Whey ChocolateAlso,  the Helpguide.com article mentioned that we should avoid sugars in any form.  My breakfast this morning comprised a fruit shake made from frozen mangoes, Zico Coconut Water, and Optimum Nutrition – 100% Natural Oats & Whey Chocolate.  The Optimum Nutrition protein drink is very tasty.  The label says, however, that it contains 8 g of Sugars in the form of honey powder and evaporated cane juice powder.  I’m guessing that is not good news but I’m very fond of it.  The Livestrong.com site has an article titled Health Risks of High Fructose Corn Syrup that sums up many of the concerns about High Fructose Corn Syrup [HFCS].  Among other things, it notes that the human body process regular sugars differently than HFCS.

A couple of excerpts from the Health Risks of High Fructose Corn Syrup article:

The human body does not process HFCS the same way it processes sugar. Fructose requires a different metabolic pathway than other carbohydrates because it skips glycolysis, or normal carbohydrate metabolism. Because of this, fructose is an unregulated source of “acetyl CoA,” or the starting material for fatty acid synthesis. Furthermore, by ingesting HFCS, a vicious cycle can ensue. This is because eating HFCS can increase the feelings of hunger.

Liver Disease & Metabolic Syndrome
Metabolic syndrome is a combination of conditions that increase the risk of heart disease, stroke and diabetes. Metabolic syndrome includes elevated insulin levels, excess body fat, abnormal cholesterol levels and increased blood pressure. The journal, “Hepatology” noted in June 2010, “The rising incidence of obesity and diabetes coincides with a marked increase in fructose consumption and is higher in individuals with nonalcoholic fatty liver disease.” Furthermore, fructose consumption is a contributing environmental risk factor for increased fibrosis of the liver.

..and, yes, I remembered to log my nutrition and exercise into SparkPeople.com site .  I’ve been less consistent about logging into the Self.com Diet Club as it’s more cumbersome.
