Watch the LCHF movie Run on Fat – with a discount or for free with membership trial

Carb loading apparently just hit the wall.

What if everything you knew about sports nutrition was wrong? What if there was no need for carbs or sports drinks when you exercise? What if you could – in fact – break records rowing across the Pacific Ocean without it?

Those are the questions behind the LCHF movie Run on Fat, which was released earlier this year. It’s the follow-up to the popular movie Cereal Killers, and it can change how you fuel your exercise sessions forever.

I really enjoyed Run on Fat. You can watch the trailer above and now the entire movie is instantly available on our membership site:

    Most of the information you give about LCHF athletes and performance come from men. I would love to see an interview or movie/video with a female LCHF athlete. Ever since I went LCHF (3 years ago) to manage my Type 2 Diabetes I've had amenorrhea. Having a a cycle where I ovulate and menstruate regularly is very important to me. I have been to 7 doctors in the last three years and they all tell me the same thing. My amenorrhea is caused by a low carb diet. I need to eat at least 100 - 150 g of carbs a day (I am more around 50g), I need to gain more weight (my current BMI is 20 after gaining 20lbs in the last three years), and exercise less (my body fat is 24% and I have totally quit HIIT training and jogging after the video from Dr. Fox).

    I have asked a few LCHF doctors (including Dr. Fung here at diet doctor) and have been told a low carb diet does not cause amenorrhea. However, all LCHF doctors have been men. I would really love to see a women not on artificial birth control be an athlete with a low carb diet and still ovulate and menstruate on a regularly. If you know of any, please include an interview or video about how she does this. A lot of your athletic posts about athletes are very men centered.

    Hi, I am a HFLC dieter, female, 41 yrs old, 14.8% body fat, strength athlete. I'm on 20 net carbs a day. I have regular periods with no adverse effects from my diet. Could by the amenorrhea has another cause. Keep investigating. Best of luck to you in future.

    Considering your history of diabetes, I would be suspicious that your amenorrhea is actually caused by PCOS(polycystic ovarian syndrome). Have you been evaluated by a reproductive endocrinologist?

    The movie links are not giving the discount...?

    I follow with interest Dr Joel Wallach, a renowned naturopathic physician, pathologist, veternary doctor, soil scientist who maintains our bodies need 90 essential nutrients on a daily basis to thrive. He says sweat contains minerals which need to be replaced when exercising. Running on water? I am questioning that. Trish
