Eat This Today, Feel Better Tomorrow: Intermittent Fasting Trial

Earlier today we highlighted some approaches to intermittent fasting and recommended a condensed eating window for those who were new to IF. Over time, many people who regularly IF with the condensed approach develop their “ideal” timing and balance to food intake during their eating windows.

For those who are new to the approach, we thought we’d offer up a simple (and easily modified) set of ideas for inspiration. Include all or some of the items in your condensed eating window, depending on your appetite and available time to cook. While we believe in including a good variety of nutrient rich food, we think it’s important to let your body’s signals guide your portions. Don’t feel you need to eat the amount you would normally eat in a regular day.

How To: Intermittent Fasting

After the great discussion last week following the 1 Meal vs. 3 Meals news post, we thought it was a great opportunity to follow up and delve into the nitty gritty of IF. Practically speaking, what does IF look like? Today we’d like to focus on the “window of eating,” a dimension of IF that got people talking last week.

Any brand of fasting can already seem a little daunting for the newcomer. (But for those whose impressions of fasting involve hunger strikes or gaunt figures sitting in meditation, we think you’ll be pleasantly surprised.) Reading about some options, and knowing your efforts will indeed be rewarded with true health benefits, makes the leap a little more inviting.

Dear Mark: Mulling Multivitamins

Dear Mark,

I’m new to your blog and am interested in taking better care of my health. I’m changing my diet and want to start a multivitamin. I go to the store though and end up bewildered enough that I don’t end up buying anything. What am I supposed to be looking for?

Not surprisingly, I get a good number of questions about supplements. Since it’s a topic I’m obviously passionate about, I’m always happy to offer advice on what my research and experience have taught me about wise supplementation.

First off, I definitely recommend the kind of product you’re looking for: a core nutrient assurance. As you know, I’m all about a good diet – a great diet, in fact. But a great diet with strategic supplementation can offer optimum health benefits A few fundamental suggestions:

Study Finds Frequent Sleep Disruption Increases Risk of Kidney, Heart Disease

A study published in the April edition of the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology suggests that frequent disruptions in the sleep cycle (also known as circadian rhythm) can increase the risk of kidney and heart disease. (The study is not yet available online.)

Conducted by researchers from the Peter Munk Cardiac Centre at Toronto General Hospital, the study altered the internal biological clocks of rodent (hamster) models using external regulators (such as reversing light and dark periods) and found that the changes resulted in cardiomyopathy (damage and enlargement of the heart) and scarring of the kidney tubules.

Based on findings from this and several other previous studies, the researchers concluded that renewal of organ tissues likely occurs during sleep, suggesting that sleep disruption prevents this process from happening and results in damage to the organs.
