Vinegar to Treat Diabetes?

Vinegar reduces blood sugar elevations after meals containing complex carbohydrates, according to the Department of Nutrition at Arizona State University.

Meals containing carbohydrates (and to a lesser extent, proteins) raise blood sugar after meals in people with or without diabetes.  [I’ve written previously about the normal ranges of blood sugars.]  Previous studies established that a single vinegar dose around mealtime lowers postprandial (after meal) blood sugar levels by up to 50%.  Arizona investigators wanted to know the best dose and timing for reducing postprandial blood sugar elevations.

They ran multiple tests on about 40 adults who reported they were generally healthy except nine had type 2 diabetes (not taking insulin). 

Findings

Mealtime vinegar ingestion reduced postprandial (two hours after meal)  blood sugars by about 20% compared to placebo.  The test meal was white bagel (variable amounts), 20 g of butter, and 200 g of juice. 

The most effective dose of vinegar was 10 g (about two teaspoons or 10 ml) of 5% acetic acid vinegar (either Heinz apple cider vinegar or Star Fine Foods raspberry vinegar).  This equates to two tablespoons of vinaigrette dressing (two parts oil/1 part vinegar) as might be used on a salad.  The authors also say that “…two teaspoons of vinegar could be consumed palatably in hot tea with lemon at mealtime.”

Discussion

The study authors suggest that the blood-sugar-lowering effect of vinegar may be related to inhibition of digestive enzymes or to a slower rate of empyting by the stomach.  Remember that most of digestion and absorption of nutrients occurs in the small intestine; the stomach first has to empty food into the small intestine.  Vinegar seems to inhibit digestion of starch but not of simple (monosaccharide) sugars.

They also note another study that found vinegar slowed the rate of stomach emptying by almost 40% in type 1 diabetics with gastoparesis, potentially raising the risk of low blood sugar.

Take-Home Points

The development of cardiovascular disease, like heart attacks and strokes, seems to be tied especially to elevations of blood sugar after meals as compared to before-meal or fasting sugar levels.  This may be related to formation of free radicals  and inflammatory mediators.  So reduction of postprandial blood sugar elevations by vinegar may be particularly helpful in preventing heart disease.  It will be many years before we can prove this by a clinical study, if ever. 

Diabetics, especially type 2’s without gastroparesis, may better tolerate grains, fruits, and legumes—in terms of lower blood sugar spikes—if they eat them in a meal that includes two teaspoons of vinegar.

Lowering Blood Pressure to 140 mmHg in Type 2 Diabetics is Good Enough

Several published treatment guidelines for high blood pressure (hypertension) recommend that type 2 diabetics aim for systolic blood pressure of 130–135 or less.  The latest research indicates that a goal of 140 mmHg is adequate. 

Details are available in the  HeartWire issue of March 14, 2010

Review: Gestational Diabetes

You can't tell if she has it just by looking

You can’t tell if she has it just by looking

Ever heard of gestational diabetes?  It’s when a when a woman develops diabetes during pregnancy.  It usually goes away soon after the baby is born.  All pregnancies are characterized by some degree of insulin resistance and high insulin levels: they are necessary for the baby.  Nevertheless, healthy pregnant women run blood sugars 20% lower than when they are not pregnant.

In the U.S., gestational diabetes occurs in 5% of pregnancies, affecting more than 240,000 births annually.  Compared to caucasians, gestational diabetes mellitus (GDM) occurs more often in blacks, native Americans, Asians, and Latinos.

So What’s the Big Deal?

Numerous problems are associated with GDM, for both the mother and the baby:

  • dangerously high blood pressure (preeclampsia)
  • excessive amount of amniotic fluid (the baby in the uterus floats in this fluid)
  • delivery requiring an operation
  • early or premature delivery
  • death of the baby
  • birth trauma, such as broken bones or nerve injury
  • metabolic problems in the baby (low blood sugar, for example)
  • abnormally large baby (macrosomia, a major problem)

Diabetic ketoacidosis—a life-threatening complication of diabetes—is rare in GDM.

How Is GDM Diagnosed?  (section updated December 28, 2013)

Most women should undergo a screening test around the 24th to 28th week of pregnancy.  Screen earlier if undiagnosed type 2 diabetes is suspected or if risk factors for diabetes are present.  The American Diabetes Association (2014 guidelines) recommends either one of two screening tests.

  • “One-step test.” It’s a morning oral glucose tolerance test after at least eight hours of fasting. Fasting blood sugar is tested then he woman drinks 75 grams oral of glucose.  Blood sugar is tested again one and two hours later.  This blood sample is obtained by a needle in a vein, not by finger prick.  Gestational diabetes is diagnosed if any of the following apply: 1) fasting glucose is 92 mg/dl (5.1 mmol/l) or higher, 2) 0ne-hour level is 180 mg/dl (10.0 mmol/l) or higher, or 3) two-hour level is 153 mg/dl (8.5 mmol/l) or higher.
  • “Two-step test.” This is a nonfasting test with only one needle-stick. The woman drinks 50 grams of glucose; plasma glucose is tested one hour later. But if it’s over 140 mg/dl (10.0 mmol/l), that’s a flunk and a three-hour 100-gram oral glucose tolerance test in the fasting state must be done (step two). Gestational diabetes is present if the three-hour glucose is 140 mg/dl (7.8 mmol/l) or higher. Other experts say the diagnosis requires two or more of the following:
    • fasting blood sugar > 95 mg/dl (5.3 mmol/l)
    • 1-hour blood sugar > 180 mg/dl (10 mmol/l)
    • 2-hour blood sugar > 155 mg/dl (8.6 mmol/l)
    • 3-hour blood sugar > 140 mg/dl (7.8 mmol/l)

You’ll find that various expert panels have proposed different criteria for the diagnosis. The National Institutes of Health in the U.S. published their consensus statement in 2013

There’s no need for the screening test if a random blood sugar is over 200 mg/dl (11.1 mmol/l) or a fasting sugar is over 126 mg/dl: those numbers already define diabetes, assuming they are confirmed with a second high reading.  A random blood sugar over 200 mg/dl (11.1 mmol/l) should probably be repeated for confirmation.  Gestational diabetes can be diagnosed at the first prenatal visit if fasting blood sugar is 92 or over mg/dl (5.1 mmol/l or over) but under 126 mg/dl (7 mmol/l), or if hemoglobin A1c at the first prenatal visit is 6.5% or greater.

Women with diabetes in the first trimester have overt diabetes, not gestational diabetes.

What’s the Treatment for Gestational Diabetes?

Briefly: diet, exercise, blood glucose self-monitoring,  and insulin if needed.  The immediate goal is to achieve normal blood sugars.

A registered dietitian is involved in teaching diet modification.  The standard recommendation is to reduce carbohydrate consumption to 35-40% of total calories.  [By comparison, the standard American diet provides about 55% of calories as carbohydrates.]  Protein and fat are about 20% and 40%, respectively.  Total calorie recommendations are based on the mother’s ideal body weight.  Insulin resistance is greatest in the morning, so breakfast is small.  Complex carbohydrates are favored over simple sugars.  Most women will achieve normal glucose (blood sugar) levels with diet modification.

Moderate exercise also helps control blood sugars, partially by increasing sensitivity of body tissues to insulin.

How often should blood sugar be monitored by the mother?  Ideally, at least four times daily: fasting (on an empty stomach before breakfast) and one hour after the first bite of each meal.

Insulin therapy should be seriously considered when fasting glucose is over 90–95 mg/dl (5.0–5.3 mmol/l) or 1-hour-after-meal glucose is over 120-130 mg/dl (6.7–7.2 mmol/l).  Fifteen percent of mothers with GDM will need insulin injections.  If elevated fasting glucose is the only problem, NPH insulin before bedtime is prescribed.  If sugar levels one hour after meals are elevated, then use rapid-acting insulin aspart or insulin lispro just before meals.  In some cases, both NPH and rapid-acting insulin are both necessary.

Outside the U.S., glucose-lowering pills are sometimes used: glyburide and/or metformin most commonly.

What About After Delivery?

Having had gestational diabetes, the mother is at high risk of developing typical non-pregnant diabetes in the future. She should be screened for the development of diabetes and prediabetes at least every three years. Regular exercise and loss of excess weight decrease the risk substantially.

MORE Health Benefits of the Mediterranean Diet

I ran across a good summary of the health benefits of Mediterranean-style eating at Medical News Today, published online May 6, 2009.  An excerpt:

The following health benefits have been observed by people who have a Mediterranean diet:

  • Longer lifespan
  • Lower risk of dying at any age
  • Lower risk of dying from heart disease
  • Lower risk of dying from cancer
  • Lower risk of developing Type 2 diabetes
  • Lower risk of hypertension (high blood pressure)
  • Lower risk of raised cholesterol levels
  • Lower risk of becoming obese
  • Lower risk of developing Alzheimer’s disease

Not mentioned above is the lower risk of Parkinson’s Disease and chronic obstructive pulmonary disease.  You’ll also find a fair description of the traditional Mediterranean diet.

Do You Hari Hachi Bu?

I loved the sound of this phrase—hari hachi bu—even before I knew what it meant.

“Hari hachi bu” comes from the Japanese islands of Okinawa.  It refers to eating a meal until you’re only 80% full, then stop eating.  It’s a method to control weight. 

Okinawa, remember, is one of the longevity hot spots in Dan Buettner’s Blue Zones

But would it really work for many in Western culture?  Probably not.  We don’t have the discipline to stick with it long-term.  Maybe for a day.

One of the currently popular dieting gimmicks is to eat every 3-4 hours while awake.  The rationale is, “you need the energy.”  If you eat 5–6 meals a day, you’re not cutting back on total calories even if you eat only until 80% full.

As long as you’re eating a fair amount of carbohydrates, you can store plenty of energy as glucose in glycogen—in your liver and muscles—to easily live without eating for at least 8–12 hours.  So, there’s no “need” to eat every 3–4 hours.  If there were, we would have gone extinct years ago.  At rest, you’re getting about 60% of your energy supplied by metabolism of fats, not carbohydrates.  Most people can live without all food, but not water, for about two months.

Plenty of people have said, “I’m going to lose weight by just cutting back on food consumption.”  I don’t have scientific data to back it up, but I’d bet that a food diary works better.

A simple weight-loss or management plan that would work better than “just cutting back” would be:

Don’t eat anything man-made

So off limits are bread, rolls, soft drinks, table sugar, high fructose corn syrup, pancakes, pizza, potato chips, Pringles, pies, cookies, cake, casseroles, cannolis, Doritos, Ding-Dongs, Snickers, etc.  I’d complicate it just a bit by avoiding naturally starchy foods like potatoes and corn.

For those who don’t like the negativity of “don’t eat that,” here’s the positive spin:

Eat only natural, minimally processed food

In other words, eat fresh fruit, vegetables, eggs, meat, chicken, fish, olive oil, nuts, etc.  These are God-made foods, not man-made.

Hello, World! Announcing the Low-Carb Mediterranean Diet

It’s here.  It’s online.  It’s free.  It’s…

The Low-Carb Mediterranean Diet

Many folks—diabetic or not—following the Ketogenic Mediterranean Diet are interested in expanding their carbohydrate options and consumption.  The Low-Carb Mediterranean Diet (LCMD) does that while aiming to control both excess weight and high blood sugar levels in diabetics, prediabetics, metabolic syndrome.  

Non-diabetics on the KMD can continue with it or move on to the Low-Carb Mediterranean Diet if they wish.  If eating a “diabetic diet” seems weird, just think of the LCMD as a low-carb Mediterranean diet—the world’s first published low-carb Mediterranean Diet, by the way.  How low-carb?  The KMD supplies about 5% of energy (calories) as carbohydrate; the LCMD goes to the 10–20% range.  [By way of reference, most people eat around 55% of caloric intake as carbs.] 

I started this whole project with the goal of helping my personal patients with type 2 diabetes gain the health benefits of the traditional Mediterranean diet: longer lifespan and lower rates of heart attack, stroke, cancer, and dementia, for example.  It’s my sincere hope that it benefits others as well.

Book Review: The New Atkins for a New You

Here’s my review of The New Atkins for  a New You, a weight-loss book by Dr. Eric Westman, Dr. Stephen Phinney, and Dr. Jeff Volek released a week ago.  The copyright holder is Atkins Nutritionals, Inc.  Under Amazon.com’s five-star rating system, I give it four stars (“I like it”).  

♦   ♦   ♦ 

The most exciting nutritional medicine development in recent memory is the fact that saturated fat consumption is not a significant cause of heart disease and premature death. The same goes for for total fat and cholesterol.  When enough physicians, nutritionists, and dietitians learn this, low-carb eating will take off like a rocket.

For those unfamiliar with the Atkins diet, it is designed for weight loss via high fat consumption and major carbohydrate restriction.  Protein intake is a bit higher than average.  As long as carbohydrates (carbs) are kept low, other foods are mostly unlimited.  Atkins has four phases.  As you graduate from one phase tothe next, more carbs are allowed, adding some carb sources before others (the Carb Ladder). 

Atkins has been around for years.  It’s not just a weight-loss diet; it’s a lifetime way of eating.

Doctors Westman, Phinney, and Volek are leaders in low-carb nutritional science.  The last time Atkins peaked (2003), we didn’t have the scientific studies backing up safety of the diet.  Now we do, in large part thanks to these guys. 

Physicians see beaucoup patients with overweight-related medical conditions.  We’re not going to recommend a diet that causes heart attacks, strokes, and other major medical complications.  Published research over the last eight years has established the relative safety of very low-carb diets, particularly Atkins.  Low-carb diets may even be healthier than the low-fat, high-carb diet that has been recommended by U.S. public health authorities for the last forty years.  Come to think of it, our current obesity and diabetes epidemics started around that same time.

The book covers nutrition basics, day-to-day practical application of Atkins eating, recipes and detailed meal plans, and the science behind the program.    

What’s New Since Dr. Atkins’ 2002 Book?

  • adaptations for vegetarians and vegans
  • adaptations for Latinos
  • coffee is now OK
  • introduction of the term “foundation vegetables” and almost doubling the amount of vegetables allowed in Phase 1: “approximately six cups of salad and up to two cups of cooked vegetables, depending upon the ones you select”
  • more flexility, such as the option to skip Phase 1 (induction)
  • focus on adequate protein intake, based on your height
  • emphasis on getting enough omega-3 fatty acids
  • no emphasis on supplements and low-carb products sold by Atkins Nutritionals,Inc.
  • diet journals—a personal record of your weight-loss journey—are recommended
  • eliminate or minimize “induction flu” and constipation (in Phase 1) by eating at least 1/2 teaspoon of salt daily [I’m skeptical.]
  • discussion of the trendy omega-6/omega-3 fatty acid ratio
  • favor monounsaturated fatty acids (e.g., olive oil, canola oil) over certain polyunsaturated fats, as in oils from corn, soybeans, sunflower, cottonseed, and peanuts
  • no mention of testing urine for ketosis
  • more discussion of psychological aspects of weight

The lack of ads for Atkins Nutritionals products is welcome and refreshing.  Too many of the official Atkins books read like infomercials, which diminishes credibility.

A vegetarian or vegan “Atkins diet” is just not something I can visualize.

What Could Have Been Done Better?

  • no specific amounts given for these recommended supplements: calcium, vitamin D, omega-3 fats, multivitamin, magnesium and other minerals (except “no iron”).  [Is the idea to encourage a visit the official Atkins website?]
  • little guidance for physicians who are to advise diabetics doing Atkins.  Few physicians are familiar enough with the program to make the necessary changes in particular diabetic medications.
  • little discussion of the constipation and leg cramps that often accompany very low-carb diets
  • the hype on the cover: “How would you like to LOSE UP TO 15 POUNDS IN TWO WEEKS!”  [To their credit, the authors note that such results are not typical.]
  • nearly all the measurements are U.S. Customary.  Metric users are out of luck.
  • four phases seem a bit much.  The beauty of Atkins Phase 1 is its simplicity. 

My favorite sentence: “White flour is better suited to glue for kindergarten art projects than to nutrition.”

My least favorite sentence: “We can’t stress strongly enough that the best diet for you is one composed of foods you love.”  I love apple pie and Cinnabon cinnamon rolls, but they won’t help me manage my weight.

The only error I found worth mentioning is minor.  The authors state that the American Heart Association recommends consumption of fish three times a week. The official policy is still “at least twice weekly.”

The book is very practical and easily understood by average people.  Most will skip the science chapters at the end.  I know the basic Atkins program works at least short-term; many of my patients have done it.

In summary, the book has nearly everything you need to be successful with the Atkins diet. 

As far as I know, there are no comprehensive long-term studies (e.g., 10+ years) regarding health outcomes of Atkins-style eating.  In other words, does Atkins have any effect on longevity, cancer, heart attacks, strokes, etc.?  But very few of the popular diets have these data either.  The best researched ways of eating in this respect are the Mediterranean diet and vegetarian diets.

My Ketogenic Mediterranean Diet and Low-Carb Eating: Six-Month Summary

I started my Ketogenic Mediterranean Diet on September 1, 2009.  After two months, I stopped compulsive record-keeping and food measurement and made a few other intentional tweaks: fish five times a week instead of seven miminum, more nuts (often two ounces a day—I like nuts and they’re convenient), less salad, more dark chocolate.  Otherwise the last four months have been similar to the initial two months of strict KMD.  My daily digestible carbohydrate intake has probably crept up to 40 g compared to 20-25 g on the strict KMD—this is still considered very low-carb. 

Accomplishments

Starting weight was 170 pounds (77.3 kg) on September 1.   After two months—8.6 weeks—my weight clearly stabilized at 155 lb (70.5 kg).  I lost the 15 lb (6.8 kg) over the first six weeks then just hovered around 155 lb.  So average weekly weight loss over the six weeks was 2.5 pounds.  Also lost a couple inches (5 cm) off my waist.

For the last four months—November through February—I’ve been eating the aforementioned liberalized KMD.  Weight has stayed around 155-157 lb (71 kg).  No calorie counting.  I eat as much as I want, except for carbs.  The experience of the first two months taught me how to eat 20-25 g of carbs in a day; it’s the gauge by which I estimate I’m eating 40 g daily now.

Has It Been Easy?

Yeah, relatively easy.  Two other adults in my house are also eating low-carb, which definitely helps.  Blogging here also helps me maintain compliance.  I promised myself to report everything—the good, the bad, and the ugly—honestly.  Accountability is important. 

Staying with the program may be easier for me than for others because I am heavily invested in it, psychologically and time-wise. 

It’s also been helpful for me to participate at two low-carb online communities: LowCarbFriends and Active Low-Carber Forums.  We support each other.  Thanks, guys.

I took diet holidays twice, for three days at both Thanksgiving and Christmas.  Gained three to five pounds (1.8 kg) each time on high-carb eating, but lost it over the next week by returning to the strict KMD.

Any Surprises?

Induction flu.  I’d never heard of it before.  Occurs typically on days 2–5 of very low-carb dieting: achiness and fatigue.  Others also experience headaches and dizziness, and it may last 1–2 weeks.

Rapid weight gain during my diet holidays (aka cheat days).  I was not gorging.  I figure the weight was mostly new glycogen in liver and muscle.  And water.

Eating fish more than once a day is a lot of fish!  Quickly boring, even unappetizing.  But that’s just me.  I need to be a more creative.  Most of my fish lately has been canned tuna.

Assuming that the Daily Values of various nutrients recommended by the U.S. Food and Drug Administration are valid, the KMD foods come up short in many vitamins and minerals.  I bet this is an issue (a problem?) with many, if not most, very low-carb diets if supplements aren’t used.  Those Daily Values are debatable, of course.  For instance, Gary Taubes argues that you don’t need much vitamin C if eating few carbs.  My nocturnal leg cramps and constipation were proof enough for me that I needed at least some supplements.  The recommended KMD supplements remedy the DailyValue shortfall in vitamins and minerals.  Dr. Richard K. Bernstein has a 30-gram carbohydrate diet for his diabetic patients and himself, as outlined in his Diabetes Solution book: no supplements are required.  

As time passes, I worry less about getting enough of various micronutrients.   I feel fine.  I’m still taking the recommended KMD supplements (5 pills a day) plus sugar-free Metamucil.   

I never had hunger that I couldn’t satisfy within the guidelines of the diet. 

No major trouble with cravings or longing for carbs.  I’ve gone six months now without whole grain bread, oatmeal, pizza, and pasta—very unusual for me.  I’d be OK never eating them again.  What I do miss are sweet, often fat-laced, carbohydrates: pie, cookies, cinnamon rolls, candy bars, cake, ice cream.  I doubt that desire will ever disappear, although it does for some who eat very low-carb.   

I counted calories only during the first two months of this experiment.  Remember, fats and proteins are unlimited.  Nevertheless, I ate fewer calories than my baseline intake.   This calorie reduction is a well-documented effect of very low-carb diets.  Fats and proteins are more satiating than carbohydrates.  It’s possible I’ve limited total calories subconsciously. 

[An interesting experiment would be to try to gain weight by over-eating fats and proteins while keeping total digestible carbs under 30 g/day.  Has it been done already?]

What’s Next?

I’d like to answer some intriguing questions.

Why did my weight loss stop where it did, at 155 lb (70.5 kg)? 

If I’d started the KMD at 270 lb (123 kg) instead of 170 lb (77.3 kg), would my weight loss have stopped at 255 lb (116 kg), 210 lb (95.5 kg) or 155 lb (70.5 kg)? 

Will two people, 300 lb each (136 kg), end up at the same final weight when following the program religiously?  Probably not, but why not?    

Six months ago, I believed many scientific studies supported the idea that a higher intake of carbohydrates is healthier, long-term, than the very low-carb Ketogenic Mediterranean Diet and other very low-carb diets.  Studies seemed to support higher carbohydrate intake in the form of traditional fruits, vegetables, legumes, and whole grains.  After reviewing the scientific literature over the last few months, I’m not so sure that higher carb consumption is necessary or beneficial for long-term health and longevity.  The evidence is weak.  Nearly all the pertinent studies are observational or epidemiologic—not the most rigorous science. 

On the other hand, I still can’t help feeling that the recommended eating styles of people like Monica Reinagel, Darya Pino, and Holly Hickman may be healthier than the KMD over the long run, at least for people free of diabetes and prediabetes.  What features unify those three?  Food that is minimally processed, fresh, locally produced when able, including a variety of fruits, vegetables, nuts, whole grains, and legumes. 

It seems that the human body is marvelously designed to survive, even thrive, with multiple ways of eating—but not all ways.   

The strongest evidence for higher carb consumption supports whole grains as a preventative for heart disease (coronary artery disease).  But the effect is modest. 

The argument against higher carb consumption is simple for people with diabetes and prediabetes: carbs raise blood sugar levels, sometimes to an unhealthy degree.  

I don’t see much role for highly processed, refined carbohydrates except as a cheap source of energy (calories).

What’s next for me is to formalize an opinion on which carbs, if any, and in what amount, to add back into the diet of those who have lost weight with the Ketogenic Mediterranean Diet.  The answer will probably be different for two groups:

  1. those who have diabetes, prediabetes, or metabolic syndrome
  2. healthy people who just need to control weight

The goal is to maximize health and longevity without tipping over into excessive carb intake that leads to overweight and obesity with associated illnesses.  

The traditional Mediterranean diet—long associated with health and longevity—is rich in carbohydrates.  The Ketogenic Mediterranean Diet—much lower in carbs—has great potential to help with loss of excess weight and control of blood sugar levels.  Does the KMD incorporate enough of the healthy components of the Mediterranean diet?  We may never know for sure.

My New Pedometer: Accusplit Eagle AE 170 XLG

Regular physical activity is a great way to help prevent regain of lost weight.  One activity available to most of us is easy, inexpensive, generally safe, and available in all climates:

Walking

I received my Accusplit Eagle AE 170 XLG pedometer in the mail today, having ordered from Amazon.com a week ago.  About $25 USD, and I got free shipping.  I thought I ordered the AE 170 instead, because I didn’t want the extra bells and whistles of the XLG.  Same price for both.  What’s extra?  You can set goals for total distance, total steps, walking time, and calories burned on the XLG.  A graph shows your progress. 

Initial Impressions

It’s smaller than I imagined: 2 x 1.3  x 0.5 inches.

Over four pages of instructions.  This will be a little intimidating for some folks.  I’m sure I’ll have to refer back to the instructions at some point.  Do you tend to lose instructions, like me?  The well-designed Accusplit website has them.

For accurate estimates of distance and calories burned, you have to input your stride length and weight.  If you just want your step count, no need to input data.  Instructions on measuring stride length are good, resulting in x feet and xx inches.  The data input screen seems to request the stride length purely in inches, however.  This was the most confusing thing about setup.  I’m still not sure I entered my stride length properly.

It’s a good thing to see an estimate of calories burned.  You might think twice about that Snickers bar if you know you have to walk five miles to burn it off.

I usually think in English units.  You can switch the device to metric  if you prefer.

I clipped the Accusplit onto my jeans and thrice walked 200 steps.  Each time the device was right on the money.  I’m happy so far.

Steve Parker, M.D.
