The example I posted was not about diet's influence on training for athletic performance.KyleAAA wrote:Have you ever trained for a marathon while eating junk food? It's a lot harder to exercise when you're eating crap than when you're eating healthy. In my experience, it is absolutely better for weight loss to eat more healthy calories than to eat fewer unhealthy calories in most cases because you will also tend to be more active as a result.
The real world example was the Twinkie diet by a KState nutrition professor. He went from a normal, diet full of mostly healthy food where he commonly ate more than 2000 calories to a 1800 Calorie diet primarily consisting of snack machine food. He lost 27 lbs in 2 months, and his other health markers improved (like LDL cholesterol).
None of this is to say that eating healthy is not important (or that only eating junk food is wise). Healthy food contains nutrients we need, but there is probably a point of diminishing returns once you get past some minimum required nutrient level for function.
Personally I think there is a lot of mysticism and placebo affect (not to mention big business) when it comes to the health food industry.
