Since the launch of NoGym two weeks ago, with this post, not only has the reception for the site been wonderful & social sharing been unbelievable (which makes me so happy, you have no idea), but the amount of insightful, positive, and inquisitive emails has pleasantly surprised me as well.

You guys have some great questions.

My goal over the course of this coming year is to fully answer every question, and some… to give you every resource you can possibly use to quench your inquisitive thirst – your knowledge-hungry minds.

The most questions, however, over the last couple weeks, have revolved around one topic: intermittent fasting.

So, in an effort to deliver on my promise of publishing nothing but super-helpful, resource-packed content on NoGym.net, I decided my efforts were best spent on putting together this fasting resource: the ultimate guide.

The goal here is not to reinvent the wheel; I’m not trying to present any novel new breakthrough information or research. I’m merely aggregating the “best of the web” on intermittent fasting…everything you need to know, and only the good stuff. The aim is to save you all the time of digging through the mountains of information out there.

Let me do the work for you. I’ll separate the wheat from the chaff, then serve you a nice hot loaf of proverbial, 100% resource-rich bread, with all the necessary vitamins & minerals.

OK, so let’s move away from the food analogies and get into the meat & potatoes of this post… oops, did it again.

Fasting To Lose Weight:

“It’s sad, but anytime you tell someone that you’re fasting, the only acceptable reasons for doing so are for medical or religious reasons. If you even mention the words “weight loss” and “fasting” in the sentence, then you’re in for a world of hurt. But in my opinion, fasting for the sake of weight loss isn’t crazy. Not at all…[Read More]

Dr. Eades and Tim Ferriss On Intermittent Fasting:

“There is evidence suggesting that intermittent fasting may have beneficial effects on the health and longevity of animals—including humans—that are similar to the effects of caloric restriction (CR).

Dear Mark: Women and Intermittent Fasting:
“Many differences exist between the two sexes. We look different. We sound different. We dress differently from each other. We like different things. Different genres of movies cause men and women to cry (differently).

#Fuckarounditis:

“I have been trying to cure people of fuckarounditis since the late 90′s, starting from the day I was first cleansed from it myself. Ever since I recognized the disease, I have acknowledged it as a serious threat to physique development and mental well-being. It is therefore with shock and horror I have watched an increasing number of people fall victim to the disease and the dubious training practices it inspires. [Read More]

Dear Mark: Post-Workout Fasting:

“For this week’s Dear Mark I thought I’d follow up on the issue of post-workout nutrition from a couple of weeks ago. I mentioned in Dear Mark: Muscle Building and Carbs that I fast once in awhile after a workout. I’ve gotten a lot of comments and messages about this point since that post. So, here’s my take on PWO fasting as promised! [Read More]

Intermittent Fasting For Athletes:

“What if your life isn’t optimized solely for weight-training workouts? And what about life beyond the barbell? Fasting for weight-training is all well and good, but we’re talking about performance here. Can fasters still perform at a high level? [Read More]

 

Wait, Is This Even Based On Any Research?

Intermittent Fasting Dissociates Beneficial Effects Of Dietary Restriction On Glucose Metabolism And Neuronal Injury From Calories Intake:

“Intermittent fasting resulted in beneficial effects that met or exceeded those of caloric restriction including reduced serum glucose and insulin levels and increased resistance of neurons in the brain to excitotoxic stress. Intermittent fasting therefore has beneficial effects on glucose regulation and neuronal resistance to injury in these mice that are independent of caloric intake. [Read More]

A Controlled Trial Of Reduced Meal Frequency With Caloric Restriction In Healthy Adults:

“Although consumption of 3 meals/d is the most common pattern of eating in industrialized countries, a scientific rationale for this meal frequency with respect to optimal health is lacking. A diet with less meal frequency can improve the health and extend
the lifespan of laboratory animals, but its effect on humans has never been tested. [Read More]

The Effect On Health Of Alternate Day Calorie Restriction: Eating Less And More Than Needed On Alternate Days Prolongs Life:

“Restricting caloric intake to 60–70% of normal adult weight maintenance requirement prolongs lifespan 30–50% and confers near perfect health across a broad range of species. Every other day feeding produces similar effects in rodents, and profound beneficial physiologic changes have been demonstrated in the absence of weight loss in ob/ob mice. Since May 2003 we have experimented with alternate day calorie restriction, one day consuming 20–50% of estimated daily caloric requirement and the next day ad lib eating, and have observed… [Read More]

Intermittent Food Deprivation Improves Cardiovascular and Neuroendocrine Responses To Stress In Rats:

“The IF rats exhibited robust hypothalamic/pituitary and sympathetic neuroendocrine responses to a different stress (swim). The IF treatment improved glucose metabolism, as indicated by lower basal levels of circulating glucose and insulin, but with maintenance of glucose and insulin responses to stress. We concluded that improvements in cardiovascular risk factors and cardiovascular and neuroendocrine stress adaptation occur in response to IF. [Read More]

Beneficial Effects Of Intermittent Fasting On The Cardiovascular And Cerebrovascular Systems: 

“Recent findings suggest that some of the beneficial effects of IF on both the cardiovascular system and the brain are mediated by brain-derived neurotrophic factor signaling in the brain. Interestingly, cellular and molecular effects of IF and CR on the cardiovascular system and the brain are similar to those of regular physical exercise, suggesting shared mechanisms. A better understanding of the cellular and molecular mechanisms by which IF and CR affect the blood vessels and heart and brain cells will likely lead to novel preventative and therapeutic strategies for extending health span. [Read More]

Alternate Day Fasting And Chronic Disease Prevention: A Review Of Human And Animal Trials:

“We review here animal and human evidence concerning ADF and the risk of certain chronic diseases, such as type 2 diabetes, cardiovascular disease, and cancer. We also compare the magnitude of risk reduction resulting from ADF with that resulting from CR. In terms of diabetes risk, animal studies of ADF find lower diabetes incidence and lower fasting glucose and insulin concentrations, effects that are comparable to those of CR. [Read More]

Apparent Prolongation of the Life Span of Rats by Intermittent Fasting:

“When a sufficient amount of choice food is available, laboratory rats, like many humans, eat enough to become more or less obese. As a consequence, the life span of rats feeding ad libitum, like the life span of their human counterparts, is presumably shortened. [Read More]

Intermittent Fasting: A “New” Historical Strategy For Controlling Seizures?:

“In antiquity, fasting was a treatment for epilepsy and a rationale for the ketogenic diet (KD). Preclinical data indicate the KD and intermittent fastingdo not share identical anticonvulsant mechanisms. We implemented an intermittent fasting regimen in six children with an incomplete response to a KD. Three patients adhered to the combined intermittent fasting/KD regimen for 2 months and four had transient improvement in seizure control, albeit with some hunger-related adverse reactions. [Read More]

Intermittent Fasting Combined With CR Is Effective For Weight Loss And Cardio Protection In Obese Women:

“These findings suggest that IF combined with CR and liquid meals is an effective strategy to help obese women lose weight and lower CHD risk. [Read More]

Anabolic Signaling And Protein Deposition Are Enhanced By Intermittent Compared With Continuous Feeding In Skeletal Muscle Of Neonates:

“These results suggest that muscle protein accretion in neonates is enhanced with intermittent bolus to a greater extent than continuous feeding, mainly by increased protein synthesis. [Read More]
