I totally freaked out when I realized that:
- this was my lowest adult weight ever (as far as I know),
- it resulted in Body Mass Index of 18.2 (anything less than 18.5 means you are way too underweight).
I'm crazy enough to try new lifestyles, but I'm not stupid enough to continue with them if the expected results are not there.
Also about the same time, I happened to read Denise Minger's life-changing critique of The China Study.
What's more, her ashtonishing example of the Tuoli people of China shows that dairy, meat and wheat are not necessarily unhealthy, as long as they are not spoiled by the Western food industry. The Tuolians also seem to lack the Western concept of food variety. For example, Tuolians don't eat vegetables, fruits, legumes, nuts, plant oils, seafood, and so on. It's really just dairy, meat and wheat, which results in the following macronutrient breakdown: 46% fat, 35% carbohydrates, and 19 % protein. Yet their total mortality and disease rates are lower or similar compared to the other counties in China.
I used to be on a high fat low carb diet before this stint with low fat high carb - I guess I'll be a medium fat medium carb paleo runner in the future. After three weeks of reduced intake of fruits (compared to a frugivore diet), I'm happy to report that my weight has normalized around 64.8 kg (143 lb), which means a 20.0 BMI. That's probably quite perfect for a marathon/ultra trail runner.
However, unlike quicker and younger dudes like Tynan, I won't start eating meat just yet. I fully accept that The China Study may not scientifically prove that animal protein is the cause of disease like cancer. Still, even bad scientists can sometimes draw the right conclusions. I believe that people changing their diets away from animal-based processed foods towards plant-based raw foods will continue to enjoy great health benefits.
According to UN and mostly anyone paying attention to our environment, a major shift like that in our lifestyles is a must, if we plan to live on this planet for much longer.
