Ben Greenfield Fitness: 399: The Latest Science On Low Carb Diets, Is Fasting An Eating Disorder, Should Lean Females Fast, How To Combat Sleep Deprivation & Much More.

Podcast Notes Key Takeaways A low-carb, high-fat diet does not impair high-intensity exercise performanceLift weights and use the sauna to avoid muscle loss while eating at a calorie deficit for weight lossShort duration (~10 minutes), moderate-intensity exercise is best for boosting moodIf you’re a lean, active female be careful with time-restricted eating/intermittent fasting“I don’t think lean females should avoid fasting, but my general recommendation is as follows: If you’re a lean, active female you really don’t need to be intermittent fasting longer than 12 hours”Why? A regular fasting protocol (especially involving fasting periods for 12+ hours) can limit both luteinizing hormone and follicle-stimulating hormone production, resulting in a downregulation of fertility. Anytime you see a downregulation in fertility, there’s also a downregulation of things like libido and overall energy levels.How far from your body should red light therapy devices, like the Joovv, be?“Typically with a red light therapy device that has a power of ~100 mW/cm^2 [like the Joovv), you can get all the benefits you need in about 5-15 minutes if you are 2-6 inches away from the device”There’s 0 evidence that a Joovv can cause harm by putting it right on the skin (just don’t leave it there longer than ~5-10 minute)

I tried it out this morning and my brain has been humming along quite nicely since about 5am. Here's the full recipe (yeah, you need plenty of ingredients, but it's worth it). Into a Nutribullet or any other heat-friendly blender, add the following: - 2 heaping tablespoons of MiCacao mix (this is a mix of cacao nibs and cacao shells that gives you the experience of drinking pure chocolate with no calories) - 2 packets Four Sigmatic Chaga mushroom extract - 2 packets Four Sigmatic Lion's Mane extract - 1 dropperful Omica Organics butterscotch toffee stevia - 1 teaspoon of a good salt (I used Colima salt) - 12-16 piping hot ounces of Kion Coffee Blend on high for about 90 seconds, then open your blender carefully as contents can expand and get foamy (and the foam is oh-so-delicious). I may or may not have also put 0.5 grams of psilocybin extract into this mix, but that's your call. ;) Bon appetit! News Flashes...5:30 Turns out a very low carb diet doesn’t seem to impair high-end exercise performance but there are SO many variables to this that I’ll unpack in next podcast. If you are eating a very low carbohydrate diet and also limiting calories for the goals of weight loss, this study shows that you sure as heck better also be lifting weights. It's so ridiculous how the media thinks "fasting" is a newfangled eating disorder. They should read this. Interesting! A new review looks into the optimum exercise intensity, type, and duration for boosting mood.

Jenny asks: You've mentioned on the podcast that fasting doesn't always work well for lean females. So should lean females like myself avoid fasting altogether? Or is there a fasting protocol you would recommend that will have a positive impact on my health? In my response, I recommend: A recent tweet: Intermittent fasting + resistance training IS effective fat loss strategy for females but they did not analyze long term effects on endocrine system, thyroid function, etc.: Get Fit Guy's Guide To Achieving Your Ideal Body Type KetoFast book by Joe Mercola (and my podcast with him) Jason Fung's "Complete Guide To Fasting" How Newborn Parents Can Sleep Better Jack asks: You mentioned in Q&A 398 about the physiological changes that occur in men when they become fathers. About a month ago, my wife gave birth to identical twin boys, and as you know, all sleep schedules go out the window.

In my response, I recommend: Sleepstream App NuCalm  (use code: BEN500 for $500 off  for the Performance and the Pro) Yoga Nidra Modafinil Qualia Mind or Qualia Focus Short frequent bursts of exercise or endurance, aerobic exercise Rotate nights, not rotate feedings Blue light blockers (Ben recommends RA Optics) when you get up at night to feed Red incandescent bulbs CBD Vape Pen (BioCBD is good brand) C-Reactive Protein Levels and Tendinitis Jackie in Japan asks: Is it possible to have plantar fasciitis and full-blown achilles tendinitis in both feet and have a C-reactive protein level of .01-.03?

The manual says it should be 2-6", but I oftentimes will put it directly on my skin to help heal an injury and it seems to be just fine. I also heard you say in a previous podcast that your wife puts the device on her face. Can you give some guidance on how close is too close?
