Fans of intermittent fasting say consuming fewers calories by skipping meals helps lose weight and leads to other health benefits.
But what happens to your body when you add exercise to the mix?
“Finding ways to lose weight that are as simple as skipping a meal is very difficult because many people find it hard to manage their hunger while being in a caloric deficit,” Eric Williamson and Matthew Lees of the University of Toronto’s Faculty of Kinesiology and Physical Education, say. “But, if they find that their hunger is well managed with intermittent fasting and they plan to exercise at the same time, then it can be an effective tool for losing fat.”
Here is what Lees and Willamson had to say about the benefits of complementing intermittent fasting with exercise.
Conventional wisdom at the time held that the more animals were fed, the better they’d fare. But McKay noticed something different: Long after the well-fed rats began to show signs of aging, those on a nutrient-dense but super-low-calorie diet retained a silky sheen to their fur, remained alert and agile and lacked the age-related health problems of their more gluttonous peers. In the end, the calorie-restricted mice also lived about 300 days longer — nearly a third of a lifetime in rat years.
Fast forward to 2020, and studies in everything from fruit flies and worms to monkeys and people have confirmed that sharply restricting calories (by 20-40 percent) while maintaining essential nutrients can fend off age-related diseases and, in some cases, extend lifespan. The problem: People like to eat, so almost no one is willing to do it. And it can be dangerous. Continue reading →
Ten years ago when I started writing this blog it was all about dieting and losing weight. It has long since morphed into a general good health and successful aging blog. Once I lost my weight it never came back because I lost my old lifestyle with it. No more eating food for the fun of it and not paying attention to getting enough exercise. I think one of the great open secrets of folks with weight problems is their sedentary lifestyle.
While I haven’t done any dieting for weight loss in years, I realize that a lot of people are interested in ways to cut back. Herewith is the Tufts Health & Nutrition Letter discussing fasting diets.
So-called “fasting” diets have recently received a lot of buzz in the media and attention from researchers as a possible means to promote weight loss and improve health. Data from animal studies are promising on several fronts, but data on humans are limited and short-term. Let’s take a closer look at the current science on this increasingly-popular diet trend.

About 6 weeks ago I discovered something called intermittent fasting. Intermittent fasting can take various forms, but the most common are a 16 x 8, or a sporadic 24 hour fast. The 16 x 8 method is when you fast for 16 hours and have an 8 hour eating window. For people that work during the daytime, it makes sense to have your last meal at 7:00 or 8:00 p.m. and then not eat again until noon or lunch time. This provides you with a 16 or 17 hour fast, essentially skipping breakfast. I have been using the 16 hour fast method on a daily basis for about 6 weeks now, and found it to be fairly easy to accomplish. The first week is probably the hardest, but fortunately it becomes easier with time. Most of the fast is spent sleeping so depending on when you get up you may…
I am posting this because it has a ton of good information about eating before working out and working out on an empty stomach. As a matter of fact, I don’t do fasting well, even the short ones, but if this kind of thing works for you, go for it.
