Short High Intensity Training Workouts (HIT) Can Help Regulate Blood Sugar

 

According to a recent study extremely short duration high intensity training significantly improves insulin action in young healthy males. Type 2 diabetes is a very health problem here in the United States and in developed countries- a veritable pandemic affecting millions of children and adults alike. While it has been conclusively established that the risk of developing Type 2 diabetes can be reduced by regular exercise [1]. It is also true that most people find it difficult to consistently follow a routine due to lack of time as conventional exercise guidelines call for at least an hour of aerobic type activity five times a week. The commitment required for such training protocols are beyond the means of most living within the constraints of the very hectic realities of modern life. As many experts in the field have noted, in order for an exercise protocol to as well as a health benefit for the individual, not only should the regime reliably modify key disease risk factors, it must also be plausible to implement.”[2]

Short high intensity training increases aerobic function and insulin action

 

Brief high intensity training workouts (HIT) have been demonstrated to produce improvements in aerobic function, but it was previously unknown whether high intensity training had the capacity to improve insulin action and hence glycemic control. The study, done published in BMC Endocrine Disorders proves that it does just that!

For the study 16 young men in their early twenties underwent a regime of 15 minute high intensity training type workouts for a period of two weeks. Aerobic performance testing as well as an oral glucose tolerance test were administered both before and after the training period. What researchers found after the two week period was that there was a significant increase in insulin action in addition to an increase in aerobic performance.

Notably the area under the plasma glucose, insulin and NEFA concentration-time curves were all reduced (12%, 37%, 26%), fasting plasma insulin and glucose concentrations were unchanged, but there was a tendency for reduced fasting plasma NEFA concentrations after training. Insulin sensitivity, as measured by the Cederholm index, was improved by an average of 23%, while aerobic cycling performance improved by 6%.

High intensity training is a realistic training paradigm to improve insulin action

 

The study concluded that: “the efficacy of a high intensity exercise protocol, involving only ~250 kcal of work each week, to substantially improve insulin action in young sedentary subjects is remarkable…This novel time-efficient training paradigm can be used as a strategy to reduce metabolic risk factors in young and middle aged sedentary populations who otherwise would not adhere to time consuming traditional aerobic exercise regimes.”[2]

Six Tips For Staying Food Illness Free For The Summer

June 16th, 2010 No comments

By following some basic food safety rules you can be food- illness free all summer!

Six Tips For Staying Food Illness Free For The Summer!

   

Diet is an important part of the process for anyone serious about losing weight and getting in shape, however in all the details about what to eat, when to eat and what not to eat, there is often little time given to the element of food safety. As the temperatures go up this summer more and more people will get sick from food poisoning and the bad part is that if you are eating several meals throughout the day, with most of those meals consisting of high protein foods, then you do indeed run a very high risk of getting sick if you are not careful with your food preparation and storage. According to the Center for Disease Control an estimated 76 million cases of food borne disease occur each year in the U.S. with most of them being rather mild cases and cause symptoms that last for a day or two. However many are indeed life threatening and the CDC estimates that there are 325,000 hospitalizations and 5,000 deaths related to foodborne diseases each year.  

Food safety is a big issue for me, mainly because had a serious run in with food poisoning about 15 years ago and it changed my life forever. It was my first summer here in the U.S. and I left the house earlier than usual for work and thus was unable to cook and take my lunch with me, as I usually do. That day for lunch I had Chinese food for lunch at a nearby take out restaurant - nothing fancy or unhealthy, mind you just some steamed vegetables. Later that afternoon however I got so sick that I woke up the next day in a hospital bed a full 17 lbs lighter than I was the day before! After that ordeal I promised myself that I would learn everything there was about food safety to ensure that this would never happen again- and so far so good- which is quite an accomplishment for someone that eats 6 plus times a day!  

I also worked for 14 years as the director of the recreation and food programs for both HIV/AIDS and the formerly homeless populations, and since I was responsible for sometimes preparing and handling food, I had to get food handling certification. When working with individuals with compromised immune systems, what might give someone else a bad day can end up costing them their lives!  That being said, I would like to pass on some very important tips for you this summer to make sure that you stay bacteria free this summer and all year round!  

Rule 1: KEEP HOT FOODS HOT AND COLD FOODS COLD!  

If I was asked what is the best overall rule of thumb for food safety, I would have to go with this one. It is so important if you are carrying food with you during the day that you keep it at the appropriate temperature. If you cook something fresh and need to eat it several hours later I would suggest that you invest in a thermos that is big enough for you to fit your food into. You can also use your thermos to keep foods cold that may have been refrigerated- just be sure to wash your thermos by hand after each use and check to see that there are no cracks before you put your food inside. That way you have a safe way of carrying your food around with you during the day!  

Rule 2: Wash your hands before you eat!  

I know I sound like a mother on this one, but I can hardly tell you how much of a difference it makes if you routinely clean your hands before eating or handling your food. A quick trip to any bathroom will show you that most people don’t know how to wash their hands. You have to wash with hot water and soap (any kind will do- it doesn’t have to be antibacterial) for at least 30 seconds to really get the germs off. Most wash for less than 10, which really doesn’t do much. A good guide is to sing the Happy Birthday song twice while washing, that will make sure you spend just enough time to wash your hands properly. If not around a water source, you can use a hand sanitizer or alcohol swabs, just don’t assume that your hands are clean and just eat.  

Rule 3: Get a thermometer for your refrigerator!  

Bacteria exist everywhere and you cannot get away from them. Under certain conditions like when they have moisture, and favorable temperatures, they grow very quickly, increasing in numbers to the point where some types of bacteria can make you sick. Bacteria grow most rapidly in the range of temperatures between 40 and 140 °F, the so called “Danger Zone,” with some forms being able to double in number in as little as 20 minutes.  

To minimize the growth of bacteria in a any unit the temperature must be kept at 40 degrees Fahrenheit or less. Unfortunately, while we humans can do a pretty good job of saying whether something is hot or cold, we cannot tell the difference between 39 degrees or 40 degrees, and that difference could make you very sick or worse. Don’t leave your temperature regulation to simple guesswork, invest in a thermometer for your fridge and you might be surprised that it isn’t always at the best temperature to keep your cold foods cold! By the way any perishable foods kept at temperatures above 40 °F for more than 2 hours should not be consumed.  

 Rule 4: If you eat out check the restaurant’s health inspection record!  

It might sound a bit involved but the beauty of the Internet is that you can access the food saftey inspection records for just about any restaurant  from your local department of health. Do a search for ‘restaurant food saftey inspections’ and you can look up where you are about to eat online. Interestingly enough, the Chinese take out restaurant that put me in the hospital had 48 violation points on their last inspection with everything from inadequate personal hygeine and unsantizited food contact surfaces to the presence of vermin in food areas. Do a quick check of the restaurants in your neighbourhood (if you live in New York you can do a check here) I’m sure that you will be surprised at how many places have sub standard food inspection reports.  

Here in New York starting in July 2010,  the health department will require certain types of food service establishments to prominently post letter grades that correspond to their sanitary inspection scores- which I am certain will go a long way in forcing a lot of food establishments to clean up their act!  

 Rule 5: Use Bleach and water to clean up!  

Whenever you handle meats, you should have a bottle with a bleach solution to disinfect surfaces that come into contact with meats in addition to washing with hot soapy water. You only need 1 tablespoon of bleach per quart of water to make an effective germ killer and it is a cheap and effective means of killing bacteria. More expensive cleaners only make the germs smell nice for a while, but do nothing to kill them, so bleach is the way to go.  

Rule 6: Use Your Sense Of Smell!  

Sounds a bit primitive, but it works! I cannot tell you how often I hear people say that the fish they ate didn’t smell too wholesome, but they ate it anyway- that might be a recipe for getting sick as fresh fish does not have any smell whatsoever! For over one hundred thousand years our sense of smell has kept us healthy by telling us when foods were not good to eat but today it is a sense that we almost ignore when it comes to food. That and the fact that most of our meats are wrapped in plastic- which does a first rate job of hiding the fact that the meat may be past its prime. When buying meat, chicken or fish, there should be no smell- none at all. Any odor is a sign of bacteria proliferation and you need to not buy it, not cook it and not eat it! For prepared foods (especially at restaurants) if your protein foods have a strange odor, don’t be afraid to send it back. It is your right as a consumer and don’t take the risk of eating it because the potential downsides really aren’t worth it.  

If the food is supposed to be served hot and is only lukewarm when you get it, or hot on the outside, but only warm on the inside, then send it back as well. It might sound like you are being a pain, but the reality is that you need to look out for your health, and if you are paying for food, it should be food that is safe to eat. Unfortunately foods don’t have to smell badly to make you sick, so it isn’t a be all and end all proposition that because there is no smell that all is well. There are two different types of bacteria: pathogenic bacteria, the kind that cause foodborne illness, and spoilage bacteria, the kind of bacteria that cause foods to deteriorate and develop unpleasant odors, tastes, and textures.  

Pathogenic bacteria can grow rapidly in the “Danger Zone,” the temperature range between 40 and 140 °F, but they do not generally affect the taste, smell, or appearance of a food. In other words, one cannot tell that a pathogen is present.  

On the other hand, spoilage bacteria can grow at low temperatures, such as in the refrigerator. Eventually they cause food to develop off or bad tastes and smells. Most people would not choose to eat spoiled food, but if they did, they probably would not get sick. It comes down to an issue of quality versus safety. I hope these tips help you stay safe and I wish everyone a happy summer!

Healthy Foods To Avoid To Lose Weight- Part 2 of 2

Healthy Foods To Avoid To Lose Weight- Part 2 of  2

 

Check out: Healthy Foods To Avoid Part 1

Are you tired of ‘eating right’ only to find that you are still out of shape and are nowhere near the body of your dreams? You can thank the wonders of modern advertising for most of your woes as the majority of so called healthy foods are in fact junk foods that will so do nothing but adversely affect your health and increase your waistline. In this the second part of my postings on unhealthy health foods we will take a look at the remaining members of the health food list that you need to avoid!

 

6. Margarine.

Whenever people gather around and cite the news, or media as a source of health information I always bring up margarine. In the 1980’s it was touted as the new health food, and a far superior alternative to butter, as it was low in saturated fats. Just as it is today, no one questioned the veracity of those statements and we seem to have ignored the fact that we know today that margarine contains the worst type of fat possible, trans fatty acids which we know well as hydrogenated oils. These fats are artificially created and the human body simply is not able to function well with this new synthetic fat that man has made to make foods last longer on the shelf and give them a smooth texture and taste. Banned in many parts of the world outright, trans fatty acids lower your good cholesterol, and hike up the bad cholesterol. It also has been linked to an increase in risk of heart disease and diabetes. Interestingly enough, this is a food that most people can remember being endorsed by the nutritional powers that be and should serve as a warning to anyone that loos to the government and expert nutritionists for information on what is healthy. 

5. Milk 

Milk is a high sodium, high fat and high sugar food that will bloat your physique and keep you from attaining the look that you are training for. We grew up hearing (thanks to the great sums of money invested by the dairy association lobbyists) that milk was the ‘perfect food’ and that’s true if you are an infant. As we get older however our ability to digest milk declines. This, along with the fact that adult mammals do not drink milk leads me to believe that milk is a food geared towards a particular stage of our development. As an adult, drink it regularly and just watch your toes disappear. If you have to drink it stick to the skim version and not the 1% and 2% variety. (Ladies, don’t worry about calcium and osteoporosis if you decides to skip milk- there are many better alternative and to be honest there are no validated studies to show that calcium loss is prevented by drinking milk or taking supplements. What has been observed is that calcium loss can be prevented by increasing weight bearing exercises and increasing exposure to Vitamin D. It doesn’t sell dairy products, but keep in mind as well that in Europe and the United States, milk is a staple, and yet we have high incidences of bone loss in our population, while many in third world countries where milk is not consumed they have no such occurrences. Sadly, contrary to the ads for milk and calcium supplementation, the studies conclusively show that bone loss has more to do with a high sodium, high caffeine, high phosphorus (from carbonated beverages) and or alcohol intake and lack of exercise and sun exposure than anything else.

4. Soy Milk.

Soy milk is one of the biggest selling soy products, with $300 million in sales in the year 2001, up from a mere $2 million in 1980 due to the advertising of its potential benefits. The irony is that this so called health food that is supposed to be a staple part of the Asian diet is virtually unknown in that part of the world. Vegetarianism itself, has become profitable for companies to promote as a result, and more and more people are trading soy over animal based proteins largely as a result of the overwhelmingly present push towards soy being a superior food source, with soy protein used for a wide variety of vegetarian friendly products. In fact you would be hard pressed to find someone that did not believe that soy was good for the body after such an extensive and pervasive campaign, but no matter how many people call an arm a leg, it remains a leg and processed soy products are not at all good for you! Refined soy products do not provide the full array of essential amino acids required by the human body and the chemical processing required to make it safe for consumption fast and  in large quantities denatures much of its useable amino acids, especially lysine. In fact, soy products are not as natural as one might think, since they are contain inherently harmful toxins such as phytic acid and protease inhibitors and are perhaps the most processed foods being consumed today. In terms of its effect on weight loss- very early on in my career I noticed that soy milk consumption made a huge difference in the amount of weight lost by my clients. My advice is to stay away.

3. Rice Cakes

One of the original diet foods. As odd as it may sound, rice cakes have a higher glycemic index than sugar- so forget about adding it to your diet if you are serious about getting and staying in shape. Again, it sounds like a great idea- as it is after all made from rice- but they are so highly refined that they are devoid of the fiber that makes rice a great food choice. Forget the advertising and avoid it and don’t even consider the chocolate and butter flavored versions.

2. Granola

A personal favorite. I love to hate granola in all of its incarnations. It is marketed in a manner  similar to the aforementioned rice cakes as a ‘health food’ with labels proclaiming that it is ‘all natural’, well, natural does not mean good for you! Granola is nothing but candy with good press. It’s chock full of sugar, fat and calories and last time I looked there is no such thing as a granola tree. Best left on the supermarket shelf.

1. Diet & Protein Shakes

Another one of those suspicious ‘health foods’- one popular brand whose name I will not mention has the ludicrous marketing slogan that life is too short not to slim fast! All of them, protein shakes included promise quick nutrition and weight loss in a gulp or two while the truth is usually far less promising. Firstly, the majority of those so called ‘shakes’ are nothing but glamorized milk shakes. That’s right- milk shakes, filled with sugar and fats, with some vitamins thrown in for good measure- the most hyped up cross filtered whey protein drink is nothing more than a milk byproduct at the end of the day and if you use them regularly you’ll see a nice rounding of your stomach over time. So forget about a quick fix- there are no quick fixes and there is a reason why we have evolved the way we have as a species to ingest solid food sources over liquid ones.

As depressing as the list may seem, there are indeed really good choices out there if you really want to lose weight and stay in shape. By choosing foods in their natural form and eating only foods that your great-great parents would recognize in the way that they ate it is the only tried and true way to help the general population take control of their health and their waistlines. It really is that simple- natural foods don’t need fancy slogans and neither do you.
