Running on an empty stomach to lose weight
Physical endurance exercise performed fasting seems more effective for burning fat than the same exercise performed after eating.
Training potentiates this effect, particularly in the woman ... ??
Energy expenditure, fasting sport and thinning
It is well known, the type and duration of physical activity has an important influence on the mobilization of energy reserves of the organism. The nutritional status of a sport (amateur or not) also affects energy expenditure.
To be physically active fasting increases the use of fat to achieve muscular work.
Significant differences between exercise fasting and exercise on a full stomach
Indeed, for the same low intensity exercise, in a normal person, the effort made fasting burns about 45% fat (by "melt" fat, a reaction called lipolysis), while after the ingestion of glucose, same effort burns half less fat ??.
This observation is also true if the effort is more intense: the use of carbohydrates is twice as important if food intake is 8 to 12 hours before the service.
Running fasting can it help lose weight?
From there to lose weight?
Presumably, as highlighted the work of a team of French researchers from the University Paul Sabatier in Toulouse.
In obese person, conditions of moderate intensity exercise mobilize 47% of fat in energy expenditure, against only 31% after eating, which, if the effort is repeated regularly and is associated with a reduced calorie diet, inevitably leads to weight loss.
Long-distance race
This effect "fat-burning" has its limits.
It is maximum for an effort of moderate intensity (jogging) after an overnight fast but fall rapidly with increasing violence of effort (fast running).
However, more effort is prolonged in time, the more the body will draw energy in fat in adipose tissue and even more if the activity is practiced fasting.
The training burns more
Accustom the body to physical effort fasting also improves the efficiency of fat oxidation, through a metabolic adaptation of the body, more favorable to the use of lipids.
The woman here has undeniable advantages over man. Indeed, at a moderate intensity exercise in obese people, lipolysis and fat oxidation is significantly better for the women.
In conclusion, benefit women and exercise of moderate intensity
In other words, women mobilize more fat than men fasting, but only for low and medium intensity exercise.

An Asparagus Cancer Cure
I really enjoyed reading the columns this past week at HealthyFellow.com. In addition to the high quality, natural health information Ive come to expect there were also a few surprises. It was interesting to learn about some unexpected connections between breast and prostate cancer, carob and heart disease and even antisocial behavior (crime and violence) and nutrition. Go figure!
Monday - Why You Should Consider Supplementing w/ Magnesium
Tuesday - Does Asparagus Really Cure Cancer?
Wednesday - Carob, Multivitamins and Saturated Fat News
Thursday - The Link Between Crime and Nutrition
Friday - The Latest Breast and Prostate Cancer News
One of the points thats often made on the HealthyFellow site is that we all need to do our part to spread the word about natural medicine. If you read something of value in a book, magazine or online ... make it a point to share your discovery with your doctor, family and friends. If you do so, the information automatically becomes so much more impactful. This is a free way to make a big difference in the lives of those around us. But its up to us to actually do it.

South Beach Diet Phase One Recipes Round up for May 2014 and an announcement
 |
| Kalyn's Phase One Recipe Picks for May 2014 were Baked White Fish with Onions, Peppers, Olives, and Feta, Stir-Fried Broccolini with Oyster Sauce, Fried Cauliflower Rice with Shrimp, Sugar Snap Peas, and Red Pepper, Shrimp and Black Bean Salad with Cilantro, Cumin, and Lime, and Baked Eggs and Asparagus with Parmesan. |
It's summer, and if I needed a reminder I got a good one when I looked at the bookmarks where I save recipe links to feature here every month and realized I didn't have one single soup, stew, or chili recipe this time. I like a good bowl of soup as well as the next person, but I couldn't be happier to say bring on the salads! But before we get to the food, I want to talk a little about these round-ups.
This post makes 74 months of writing monthly South Beach Diet Phase One Recipes Round-Ups for the blog, and times have changed. I still love the South Beach Diet, but now a lot of people reading my blog follow other types of low-carb or grain-free eating plans. (That was the reason I gave the blog a makeover last year, adding new tabs so recipes could be sorted by diet type.) After asking for opinions on Facebook and giving it a lot of thought, I've decided to make the monthly round-ups more broadly focused, hopefully making them more useful for people who aren't strictly following South Beach. I'll still include recipes that are South Beach Diet Phase One of course, but I also want to spotlight interesting recipes that are Low-Carb in general, Paleo, Whole 30, and possibly others. As always, all the recipes in the round-up will be grain-free, making them Gluten-Free as well, and there will be some type of labeling system to make it easy to see which recipes are Phase One or another plan. That new format will be coming next month; hope you like it. And if you have any thoughts about this, please share them in the comments!

Nitrates Caffeine An Ergogenic Sledgehammer For High Intensity Cycling 46 Improved Time Trial Performance
 |
| You better make sure you are competing in / training for the right sports before you spend you get all excited about a 46% performance increase |
Personally, Id say that this is mostly a result of the disappointment of users of the mostly extremely underdosed "nitrate supplements" experienced. The not exactly earth-shattering effect sizes that have been reported in many of the more recent studies were are another factor... the 46% increase in time-trial performance and the albeit non-significant 27% difference to the caffeine-only trial, on the other hand, has the potential to rekindle the interest of any athlete for whom longer duration high intensity work at 80% of his / her individual VO2max doesnt sound like HIIT gone wrong ;-)
Whatever, ... the big news is that the effects add up perfectly
Within the health and fitness community people are always on the lookout for new pills to pop. If you look at the "regimen" some of them post on pertinent bulletin boards, you sometimes have to scratch your head and ask yourself, whether this guys & gals even eat anything else but supps.

| If this looks only remotely familiar, you are probably not following the "Three Simple Rules of Sensible Supplementation" | learn more |
In other words, unless you are aware that the benefits Handzlik and Gleeson observed in their fourteen well-trained male subjects wont necessarily be useful, maybe not even noticeable unless you practice sports where HIT (without the 2nd "I" for interval) is part of the training or even competition.
