A lot of people don’t exercise because they think they have to spend a lot of time doing it every week, and that does not appeal to them.  Let’s see what research has found.

Several years ago research was conducted on what was called high intensity short interval training. Since the start of that, a lot of research has been published on that topic, experimenting with different durations of exercise.

The original research started using a stationary bike doing 30 seconds intervals, peddling as hard as possible, then resting for up to 4 minutes. This was then repeated 4 to 6 times.

This regime was very effective documenting that just 2 minutes of actual exercise time produced the same results as an hour of regular intensity aerobic exercise.

So how little can you exercise and still improve your performance? Is 30 seconds interval as low as you can go?

The following research tested six sub elite triathletes comparing them with 6 endurance-trained sub elite athletes maintaining their normal training routine .(Jakeman J, et.al., 2012).

These athletes were already in good shape. It’s harder to improve the performance at that level, compared to starting with people out of shape.

6 of the participants did 10, 6 seconds sprints on a stationary bike with a resting period of 1 minute in between, 3 times a week for 2 weeks. The resistance on the bike was set to 7.5% of the body weight.

Two weeks of the high intensity short interval training resulted in a 10% decrease in a 10-km time trial.

The time taken to reach the onset of blood lactate accumulation, defined as the point where blood lactate reaches 4 mmol·L⁻¹) was significantly increased. This is another way of measuring improved aerobic fitness.

The actual exercise time was only 1 minute 3 times a week.

It is amazing, spending only 3 minutes a week for 2 weeks can improve aerobic performance.

If you want to improve cardiovascular fitness, but want to spend as little time as possible exercising, this is the way to do it.

You need a stationary bike to implement this protocol, but if you have that at home, you don’t necessarily even have to do the 10 sprints at one time. You can split them up throughout the day depending on what’s most convenient for you.

Other studies has documented that it is more beneficial to be active several times a day compared to exercising longer only once a day.

Lack of time is no longer a valid reason not to exercise. Most people would most likely have 3 minutes a week to spend on exercise considering the benefits.

How do you think stress affects your metabolism?

Fotolia,fatYou don’t want to have a slow metabolic rate because that would make it harder to maintain a lean body composition.
You can probably also agree that most of us are exposed to plenty of stress during a average day.
 

I think you will find the reviewed research interesting because it investigated how stress may affect our metabolic rate (Kiecolt-Glaser JK, et al. 2014).
 

Fifty-eight healthy women, with the average age of 53.1 years, participated in the study and were given high fat test meals. The day prior to eating the test meals, stressors were also assessed using a standard test. Fat and carbohydrate oxidation, triglycerides, cortisol, insulin and glucose were measured before and after the 2 high fat meals.

It was found that greater numbers of stressors were associated with lower fat oxidation after the meals and also higher insulin levels. The difference between stressors the day before and no stressors turned out to be 435 kj which is approximately 104 calories. The researchers estimated that it could add up to almost 11 pounds per year in weight gain.

This means that stress can contribute to weight gain.

You may not be able to control the factors contributing to stress, but you can, with some training, control how you react to stress.

In other words you can make yourself more stress resistant.
Meditation is a great tool for that.

How healthy is green tea?

Grüner TeeGreen tea seems to be one of the best things you can drink for your health. One of the reasons is that it contains a lot of antioxidants.

One of the most important things we can do to stay healthy is to be sure we stay insulin sensitive. When we are insulin sensitive the glucose is transferred from the blood into the cells very easily without the pancreas having to release a lot of insulin. This will keep the blood glucose at a low and normal level, and also help to keep inflammation low, both are very important if we want to be healthy.

The reviewed research investigated if green tea could improve glucose control and increase insulin sensitivity(Liu K, et.al.,2013). 17 studies were included in the analysis. It showed that green tea consumption significantly reduced the fasting glucose and Hemoglobin A1c. Hemoglobin A1c is a test for long-term glucose control.

If you don’t like green tea and if you want to be sure your green tea does not contain a lot of pesticides, you can take it in capsule form like our Better Green Tea formula which meets the German standards for pesticide content, which is very strict.

Could gluten cause problems for everybody?

Posted by on 8:17 am Eating, Inflammation, Inflammatory factor, Insulin resistance, metabolic syndrome, Low glycemic meals, The Learn to Eat Plan, Weight loss, Wellness | 0 comments

3d render of digestive systemThere is more and more information published every day on adverse reactions to gluten.

We used to believe that if you did not have celiac disease, you would not have any issues with gluten. This does not seem to be true since there are different degrees of gluten intolerance. People who have celiac disease just have a very severe reaction to it.

A gastroenterologist and researcher at Harvard University has published a very interesting article on this subject(Fasano,A,2011).

The intestinal mucosa act as a barrier to protect us from pathogens and other particles that are not supposed to be absorbed into the blood. This is called intestinal permeability. Dr. Fasano explains that gliadin (a protein found in gluten) trigger IL-8 (an inflammatory cytokine) leading to recruitment of neutrophils. Neutrophils are a type of white blood cell which are activated as a part of the body’s defense mechanism.

Gliadin increases intestinal permeability through the release of a substance called zonulin. When the intestinal permeability increases we may absorb both pathogens (bacterias) and larger proteins not intended to be absorbed, triggering an inflammatory response.

Gliadin also interacts with macrophages, another type of white blood cell. This establishes an inflammatory environment in the intestinal mucosa. Depending on genetic predisposition, we will then experience a more or less severe reaction. This may, for example, trigger an autoimmune response in someone who is predisposed to that.

In other words, it looks like gluten is triggering an inflammatory response in everybody, but because we don’t have exactly the same genes, we will not have exactly the same reaction.

Gluten is found in common grains, but gluten free grains are not without problems either because they elevate the blood glucose high.

There are; however, solutions to this which you will find in the Learn to Eat program.

Interesting reason why you may gain fat around your waist.

Woman's fingers measuring her belly fatWhen you notice that you have gained fat around your waist, it usually also means that you have gained visceral fat.

Visceral fat is fat deposited around your inner organs, and is contributing to metabolic dysfunction and inflammation.

The reviewed research is very interesting because it investigated if there was a connection between an increase in waist circumference, visceral fat, and increased intestinal permeability (Gummesson A, et al. 2011). Intestinal permeability is a way to tell if we are absorbing particles into the blood that were not meant to be absorbed. The mucosal membranes of the intestinal tract are supposed to protect us from absorbing pathogens like bacteria’s and also large protein particles that were not meant to be absorbed. Our body will attempt to defend itself by triggering inflammation when we absorb particles that we are not meant to absorb.

 In this study, waist circumference and intestinal permeability were measured, and computed tomography and dual energy X-Ray were also used. A positive correlation was found between waist circumference and intestinal permeability. Visceral fat and liver fat also correlated with increased intestinal permeability.

It is important to have normal intestinal permeability and a well functioning gastrointestinal tract for many reasons, and it may also help you in keeping your waist slim.

Not all exercise burns fat equally.

Posted by on 11:01 am Body fat, Eating, Exercise, General Health, Get in shape, Intensity Training, Weight, Weight loss | 0 comments

Gym CyclingHave you accepted this truism: that the more physically active you are, the less likely you are to gain weight? Here is the catch: not all exercise is equally effective when it comes to burning fat. The good news is you don’t have to exercise for several hours a day to make a difference.

The reviewed research is very interesting and the results may surprise you. Healthy young men were divided into three groups: one control group did not exercise, one group did moderate intensity exercise at 50 percent Vo2peak for 60 minutes, and one group did high intensity exercise, alternating 2 minutes at 90 percent Vo2peak with 2 minutes at 25 percent Vo2peak(Trombold JR, et al. 2013). The energy expenditure was the same for both exercise groups.

The participants were provided a test meal the morning after the exercises. Tests were performed fasting before the meal, and 2, 4, and 6 hours after the meal.

The results showed that even if the participant had similar energy expenditures the high intensity exercise was more effective in lowering triglycerides after the meal. The high intensity was also more effective in increasing fat oxidation which means the high intensity exercise burned more fat.
