Chew more thoroughly for better health and weight loss

Gandhi’s advice to chew your drink and drink your food has stood the test of time. Although what you eat is important, how you eat deserves equal attention as research shows chewing thoroughly and eating slowly helps prevent weight gain and improves digestion.

Chewing more thoroughly suppresses appetite

A series of recent studies show chewing each bite thoroughly reduces appetite, lowers calorie intake, and can aid weight loss. That’s because the hormones that leave us feeling satiated don’t kick in until 20 to 40 minutes after you begin eating.

For instance, one study measured the release of gut hormones that suppress appetite in subjects five minutes and 30 minutes after they consumed a meal. The results showed eating the meal more slowly increased the secretion of appetite-reducing hormones.

In another study a group of both lean and obese men ate the exact same meal twice in one day. For the first meal they were instructed to chew each bite 15 times and for the second meal, 40 times. The results showed that whether lean or obese, the men consumed 12 percent less food when they had to chew each mouthful 40 times.

Another recent study showed lengthening the time of your meal can decrease hunger, something many European cultures practice regularly. Stretching a meal over two hours by taking breaks makes the food seem more rewarding, lowers grehlin, a hormone that induces hunger, and raises hormones that increase satiety.

Chewing thoroughly improves health

Digestion starts in the mouth, not the stomach. Saliva contains enzymes that begin the breakdown of fats, carbohydrates, and proteins. Exposing food to saliva for longer periods of time in your mouth creates less stress on the rest of the digestive tract, which frees up more energy so you feel better.

Taking the time to eat slowly and consciously also gives the digestive tract ample notice to secrete stomach acid, pancreatic enzymes, gallbladder bile, and other chemicals to completely digest your food for maximum nutrient absorption. By wolfing down your meal you throw improperly digested food into an unprepared digestive system, which is stressful and can create symptoms of bloating, gas, constipation, diarrhea, or stomach pain.

Because the immune system resides largely in the gut, chewing thoroughly is one way to promote better immune health.

Healthier foods require more chewing

You may have noticed that many processed and fast foods are so easy to chew you hardly need teeth. Whole foods, on the other hand, tend to require more chewing. Simply choosing a whole foods diet free of refined foods can encourage you to chew more thoroughly.

However, you may need some outside reinforcement to develop a better chewing habit. Here are some strategies:

• Take the time to sit down and calmly eat a meal
• Take small bites
• Count so you chew each mouthful 20 or more times—until your food is completely liquid
• Pay attention to the taste, texture, and flavor of your meals; avoid reading or watching TV while eating
• Try to make meals into lengthy, relaxing occasions as often as possible

Why eating breakfast prevents weight gain and fatigue

Breakfast is the easiest meal to skip—mornings are rushed and many people don’t have an appetite when they wake up. Some people even feel nauseous in the morning (which indicates a blood sugar disorder). But if you skip breakfast you may be sabotaging your weight loss efforts, increasing your risk of obesity and blood sugar disorders, and robbing your brain of energy.

Skipping breakfast associated with obesity

Numerous studies show skipping breakfast is associated with higher rates of obesity in both children and adults. Some people erroneously think that by skipping breakfast they consume fewer calories and thus aid weight loss. However, skipping breakfast can set into motion an unhealthy metabolic cascade that eventually leads to excess fat.

Breakfast is the first meal after a long night of fasting. In the absence of food, the body must release stored glucose to fuel the brain or create glucose by breaking down muscle tissue. This process is made possible by stress hormones.

Skipping breakfast when your brain and body are starved for energy exaggerates this stress response, forcing the body to continually pump out stress hormones to fuel the brain. These stress hormones also explain why some people wake up feeling nauseous. Although it seems counter-intuitive, eating can actually relieve that morning nausea by inhibiting the stress response.

The habitual stress response caused by skipping breakfast and other meals promotes weight gain, upsets hormonal balance, causes inflammation, hinders brain function, and can lead to symptoms such as migraines, depression, mood swings, shakiness, lightheadedness, brain fog, sleep disorders, and more. Eating meals high in sugar and carbohydrates also contributes to this problem by causing energy to continually spike and crash throughout the day.

Eating breakfast is an important strategy when it comes to preventing weight gain and fatigue.

Skipping breakfast makes you more prone to overeating or poor food choices

Skipping breakfast can increase your chances of overindulging or making poor food choices later in the day. When your energy is crashing and your brain is starving for fuel, downing a caramel latte or package of mini donuts suddenly seems unavoidable. A well-fueled brain is better equipped to make healthier choices and not succumb to a mad grab for the nearest source of quick energy (for which the American food industry seems to be designed).

A recent study validated this tendency, showing participants who skipped breakfast were more likely to seek out high-calorie junk foods and that dieters who skip meals are more prone to gain weight over the long run. Their brain scans showed skipping meals stimulated the brain in a way that made high-calorie foods seem more appealing. Those who skipped breakfast also ate about 20 percent more at lunch.

Breakfast keeps body and brain on an even keel

Breakfast should emphasize healthy proteins and fat (avoid sugary, starchy breakfasts) to start the day on an even keel and maximize brain function. Eat frequently enough to avoid blood sugar crashes, and include protein, healthy fat, and fiber (vegetables) with every meal to sustain energy and prevent fatigue throughout the day.

The importance of keeping a food diary

Whether you want to lose weight or manage an autoimmune disease, studies show keeping a food diary is one of the best ways to ensure success. For instance, diet research shows those who keep a food diary lose 30 to 50 percent more weight than those who don’t.

Keeping a food diary keeps you honest

It’s easy to think you are eating or behaving one way when the reality is strikingly different. Keeping track of everything you eat, portion sizes, and when you eat lifts the veil on bad habits you have managed to hide from yourself, such as how much sugar you really eat, how big your portions are, how frequently (or infrequently) you eat, or how often you eat a food you know causes problems for you.

Keeping a food diary for weight loss

One of the most popular reasons to keep a food diary is for weight loss. Most people underestimate portion sizes or how often they eat. Measuring the peanut butter or mayonnaise may show you’re eating much more than you thought.

Knowing you have to record everything is also great motivation to stick to your plan. That tantalizing dessert loses appeal when you see how those extra calories or grams of carbohydrates are going to kill your numbers at the end of the day. On the other hand, jotting down your exercise feels great.

It’s also good to tie in timing, location, and emotions with your meals. You may notice waiting too long between meals predisposes you to a binge, or that a particular person or situation increases your sugar cravings.

Keeping a food diary for health changes

Food diaries aren’t just for weight loss. Many people must make dramatic dietary changes to manage a chronic health condition. Autoimmune diseases such as Hashimoto’s hypothyroidism, multiple sclerosis, psoriasis, and rheumatoid arthritis all respond positively to changes in diet. Tracking both what you eat and your symptoms not only helps with compliance, but also can show you if any foods flare up your condition. For instance, you may be following a gluten-free and dairy-free diet but notice your health worsens when you eat eggs.

Keeping a food diary to find food intolerances

In fact, a food diary is an excellent tool for an elimination-provocation diet. These diets involve eliminating common dietary immune triggers such as grains (gluten in particular), dairy, eggs, soy, and sweeteners for a number of weeks. After the elimination period you add in each food one at a time every 48 to 72 hours and monitor your reactions.

Most people don’t realize they have a food intolerance because either they eat the food all the time or because reactions can happen up to 72 hours later. By removing the foods for a period of time and then introducing them singly, the immune system will typically produce a noticeable reaction if that food is an issue. It’s important to record symptoms as they appear. They can be very diverse and affect the skin, digestive tract, respiratory system, mood, mental function, joints, and more.

Are you always hungry? You could have leptin resistance

You would think people who are overweight or obese would never feel hungry—after all, they have all that extra fat to burn. But in a cruel twist of metabolic trickery, carrying excess fat can actually make you hungrier thanks to a phenomenon called leptin resistance.

What is leptin?

Leptin is a “satiety” hormone secreted by fat cells that tells the brain when you have had enough to eat. Eating causes the secretion of leptin, which signals that the stomach is full and it’s time to stop eating. Between meals or during long periods without food, leptin levels drop, triggering hunger and motivating you to eat and replenish the body’s energy stores.

Leptin resistance causes you to always feel hungry

Because fat cells secrete leptin, overweight and obese people should never feel hungry. Unfortunately, the reverse happens. Excess fat secretes too much leptin, bombarding leptin receptors on cells. Eventually these cells become overwhelmed and shut down their leptin receptors to protect themselves. This is called leptin resistance—leptin can no longer get into the cells to deliver their message that the stomach is full and it’s time to stop eating.

Hence the leptin-resistant person always feels hungry and is prone to overeat, even if she or he is carrying plenty of fat. In addition to causing chronic hunger, leptin resistance doubly vexes the overweight person by promoting fat storage and making it tough to lose weight.

Leptin serves other roles beyond hunger and satiety. It is also important for fertility, libido, and puberty. Leptin resistance could explain why obese girls are 80 percent more likely to start puberty earlier than girls of normal weight.

High triglycerides block leptin

High triglycerides have been shown to block leptin. Diets high in alcohol, sugars and carbohydrate-rich foods, such as breads, pasta, rice, and potatoes, raise triglycerides considerably. High triglycerides have been shown to block the ability of leptin to pass into the brain to tell it you’re full.

Diet can reverse leptin resistance and chronic hunger

The key to unwinding leptin resistance is to adopt a diet that will restore leptin sensitivity. The eating habits that typically lead to being overweight or obese—overeating and eating too many sweets and starchy foods, processed foods, and foods fried in industrialized fats—also lead to leptin resistance, high triglycerides, and hence the feeling of always being hungry.

To restore leptin sensitivity, diminish chronic hunger, and release excess fat, consider the following leptin facts and begin making the changes you need to your own diet and lifestyle.

• Regular exercise, particularly strength training and interval training, lowers leptin.
• Sugar, corn syrup, and high fructose corn syrup found in sweets and sodas make the brain resistant to leptin. Sweets also raise triglycerides so leptin can’t reach the brain.
• Healthy fats activate leptin’s satiety switch. Eat coconut oil, butter, ghee, olive oil, avocado, salmon, etc. as part of a lower-carb diet.
• Omega-3 fatty acids regulate leptin sensitivity. Ask your practitioner whether a fish or krill oil supplement may help you.
• Overeating causes leptin resistance. Ditch the sodas, sweets, processed foods, and high-carbohydrate foods, which trigger cravings in many people. Healthy fats and sufficient protein curb cravings. Consider hypnotherapy, acupuncture, or other tools to address an eating disorder that may cause you to overeat.

Mother’s inflammation raises risk of child’s autism, asthma, and allergies

While practitioners of functional medicine have long understood the link between the health of a mother’s immune system and the risk of giving birth to a child with autism, asthma, allergies, and other disorders, it is validating to see this information in the New York Times: An Immune Disorder at the Root of Autism.

In this article, the author reports one-third of autism cases are the result of an inflammatory disease that began in the womb, thanks to the mother’s imbalanced immune system. Looking back through 20 years of data, researchers discovered that infections during pregnancy increase the risk of autism. Hospitalization for a viral infection (i.e., the flu) during the first trimester tripled the odds for autism, while a bacterial infection (including urinary tract infections) during the second trimester increased the risk by 40 percent.

Maternal autoimmunity increases risk of autism in children

While viral and bacterial infections have declined over the last 60 years, autoimmune and chronic inflammatory disorders are steadily climbing. Autoimmune disease dwarfs cancer and heart disease combined, now affecting about 50 million people, or 20 percent of the population.

Investigation revealed it isn’t the infections themselves that cause autism, but instead the reaction of the mother’s immune system to infection (her inflammatory response), as well as the overall health of her immune system.

One study of 700,000 births found that a mother’s rheumatoid arthritis, celiac disease, or Type 1 diabetes more than doubles the risk of autism in her child. Other research has connected additional autoimmune diseases, such as Hashimoto’s hypothyroidism, with an increased risk of giving birth to a child who develops autism.

In an autoimmune response, the immune system mistakenly creates antibodies to the body’s own tissue, thereby tagging the tissue for destruction. Researchers have found that some mothers of autistic children create antibodies to the brain tissue of their fetus, meaning the child is a born with a brain already developmentally imbalanced by immune destruction. In fact, research indicates that mothers of children with autism are five times more likely to have anti-brain antibodies in their systems.

Chronic inflammation in pregnancy raises risk of childhood disorders

Other risk factors for autism include maternal asthma, allergies, insulin resistance, obesity, and chronic low-grade inflammation. In other words, when a mom’s immune system is in constant overdrive—never getting the opportunity to rest—the development of the fetal brain is adversely affected and the overall risk for disorders is increased.

Western diet and lifestyle behind inflammation and autoimmunity

Unfortunately, the story An Immune Disorder at the Root of Autism veers into the promise of using whip worms—yes, worms—to tame the out-of-control immune system. The theory is that autoimmune disease has skyrocketed in developed nations because we are too clean.

The article fails to mention those other hallmarks of Western civilization besides good hygiene: overabundant diets laden with sweet, starchy, processed foods; chronic stress; a sedentary lifestyle; and daily bombardment of environmental toxins.

Thankfully, practitioners of functional medicine have measures other than the whip-worm therapy to manage autoimmune diseases and chronic inflammation, all backed by peer-reviewed science. These include an autoimmune diet and the use of targeted, customized nutritional therapies.

Ask my office how we can assist you in balancing your immune system and, in so doing, help you to lower the risk of giving birth to a child with asthma, allergies, autism, or other brain and immune disorders.

Wake up at 3 a.m. and can't fall back asleep? Consider low blood sugar

Do you consistently wake up around 3 a.m. and can’t fall back asleep? Although the reasons for sleep problems can be complex, waking up too early is often a symptom of hypoglycemia, or low blood sugar, and can be remedied through dietary changes and nutritional therapy.

Why you wake up at 3 a.m.

The brain is highly active at night, transforming short-term memory into long-term memory and carrying out repair and regeneration, and it depends on a steady supply of energy to do these tasks. When you sleep at night your body goes into a fasting state. In order not to deprive the brain of the food it needs for energy, the body compensates by gradually raising cortisol, an adrenal hormone. Cortisol stimulates the body to release or create glucose to supply the brain with energy during the night-long fast.

Chronic low blood sugar, however, throws a kink in this process. People with hypoglycemia tend to have difficulty making the right amount of cortisol at the right times of the day or night. They also have blood sugar levels that spike and then crash throughout the day. If they go too long without eating they experience lightheadedness, irritability, shakiness, a spacey feeling, and other symptoms that signify the brain is not getting enough glucose.

In these cases, not only does blood sugar drop too low during the night, but the adrenal glands don't produce enough cortisol to keep the brain fueled. In response, the body sounds the emergency alarm by releasing “fight-or-flight” hormones. These stress hormones raise blood sugar back to a safer level. Unfortunately, they also raise stress, which can cause anxiety or panic in the middle of the night. Hence the waking up at 3 a.m. and not being able to fall back asleep.

How to fall asleep if you wake up at 3 a.m.

A quick fix for waking up at 3 a.m. can be as simple as eating a small amount of protein, with perhaps some fat thrown in—a spoonful of nut butter, a little bit of meat, or a hard-boiled egg. For some people this raises blood sugar to a healthier level and sustains it so they can fall back asleep. It’s best not to eat something sweet or starchy (however tempting to your hungry brain) because this will just cause blood sugar to spike and crash again.

Daytime tips to avoid waking up at 3 a.m.

Although a 3 a.m. snack may help you fall back asleep, it’s better to prevent that anxious awakening in the first place. If you wake up regularly at 3 a.m. you may suffer from chronic low blood sugar and need dietary therapy. Symptoms include:

• Sugar cravings
• Irritability, light-headedness, dizziness, or brain fog if meals are missed
• Lack of appetite or nausea in the morning
• The need for caffeine for energy
• Eating to relieve fatigue
• Energy crashes in the afternoon

A diet that stabilizes daytime blood sugar levels will have you sleeping better. This requires that you:

• Never skip breakfast and eat a breakfast lower in carbohydrates. If you have chronic low blood sugar you may have lost the ability to feel hunger and you need to eat in the morning and throughout the day (even if you don't feel like it).
• Eat frequently enough so blood sugar does not crash.
• Ditch the sweets and starchy foods and adopt a lower-carbohydrate diet. People with low blood sugar symptoms typically eat too many sweets and starchy foods (breads, pasta, rice, potatoes, etc.) and also frequently skip meals. Go for foods lower on the glycemic index and eat enough protein and healthy fats to sustain your energy.

A variety of nutritional compounds can further support your blood sugar handling and stress hormone functions so you sleep better. Ask my office how we can help.

Vitamin B12 deficiency more common than thought

Vitamin B12 deficiency is more common than people realize and can mimic or cause other disorders. A B12 deficiency is linked with memory loss, anemia, cardiovascular disease, and autism, to name a few. B12 is necessary for the brain and nervous system to function and for other aspects of health. It’s believed B12 deficiency is due in most cases not to lack of dietary sources but to poor absorption of the vitamin in the digestive tract.

Could your declining brain function be a B12 deficiency?

Because B12 is so vital for brain function, a B12 deficiency can manifest as numbness and tingling in the hands and feet, shakiness, depression, and loss of memory and cognition that can mimic the beginnings of dementia. It’s especially important to pay attention to a possible B12 deficiency in older people as the ability to absorb the vitamin declines with age. Studies show older people with higher B12 levels show less brain shrinkage and cognitive decline than their B12 deficient counterparts.

Is your anemia a B12 deficiency?

Other common manifestations of B12 deficiency are symptoms of anemia, which include fatigue, lethargy and weakness. Many people with B12 anemia discover they have an autoimmune disease called pernicious anemia, which inhibits the absorption of B12. In this case managing the autoimmune disease is important as well as supplementing with B12 sublingually or through injection.

A deficiency in B12 is also linked to an increased risk of cardiovascular disease, autism, autoimmune disease, infertility, and more.

B12 deficiency often due to poor absorption

So what causes B12 deficiency? For many people it’s due not to diet but rather to poor absorption of nutrients.

Many people today have damaged guts due to diets high in inflammatory foods, chronic stress, and food intolerances, such as to gluten. It’s difficult for nutrients such as B12 to pass through an inflamed and damaged gut lining into the bloodstream.

Other factors that can lead to a B12 deficiency include a decline in stomach acid (common in elderly), the use of antacids and acid-blocking drugs, the use of metformin and other prescription drugs, alcoholism, and weight-loss surgery.

Repairing and restoring gut health should always be addressed in the event of a B12 deficiency.

Vegans and vegetarians at risk for B12 deficiency

One group at risk for dietary deficiency of B12 are vegans and vegetarians—B12 is only found in animal foods. Natural plant sources of B12 such as spirulina, algae, seaweed, or grasses are poorly absorbed and may give a false reading of normal B12 on a lab result. This population especially should supplement with B12.

Also, although gut bacteria can synthesize B12, this requires healthy gut function and flora, and most of it is synthesized downstream of the small intestine where B12 is absorbed.

Taking B12

Recommended doses of B12 vary depending on whether you have a deficiency, and you should work with a qualified health care practitioner to determine the best dose. However, there is a low risk of B12 toxicity.

The more bioavailable form of B12 supplementation is methyl B12, or methylcobalamin, as opposed to the more common, synthetic cyanocobalamin. Not only is methyl B12 more neurologically active, it also enhances a liver detoxification process called methylation, which can reduce inflammation.
