Running burns more CALORIES than walking. But that doesn't mean it burns more FAT.
Because different kinds of muscle cells are active during vigorous movements and gentle movements and because these fibre types each burn a different fuel, it is possible to burn a huge amount of fuel while using up a TINY quantity of FAT.
Sugar is burnt by muscle fibers that produce powerful movements. Burning sugar makes you TIRED and HUNGRY,so that you need to stop for recovery and eat more.
The fibres that burn FAT are 'fatigue resistant' ; using them won't make you weary, or increase you appetite. They don't produce Lactic Acid (a breakdown product of sugar) so your legs won't feel 'rubbery' . You can keep a fat burning activity going indefinitely.
Most activities use BOTH fibres types but you can 'tip the balance' by working more gently (using more fat because you use less sugar ) for longer , or by working out vigorously (more sugar) in short bursts.
By working gently enough to keep going continously , you can EASILY BURN MORE CALORIES in a day than by doing short , exhausting sessions. (The processes involved in 'recovery ' also mainly burn sugar , so 'elevated metabolism' during rest is NOT helping to burn fat either
By working more gently your body will 'capillarise' more effectively (building new blood vessels) and control the blood flow better in the vessles its already got. By building up the capillaries in your Cardiovascular system , you will improve the avilablity of oxygen to your muscles.
Walking fast can burn more sugar than running slowly. But walking slowly burns more fat than either of these. Bottom line, for fat loss lift weights varying rep ranges and go for long walks .
And to the sprinter's physique comments you make. Have I ever seen a fat sprinter. SURE I HAVE. Did ever see the guys in the NFL? They sprint and many are fat. Do a google search of Masters Sprinters - many are fat. The Olympic sprinters physiques are the result of WEIGHT TRAINING NOT sprints.
Now do a google search of the imgaes of hunter gatherer types who WALK. THEY are LEAN. They don't sprint much, if at all.
As far as observational evidence look at the great health of Fauja Singh a 97 year old a vegetarian distance runner and a British man named Martin who is 101 years old and full of energy. You will hard pressed to find anyone as well off as them at that age.

There is no scientific evidence the sprint program you propagate leads to a longer healthier life. Our ancestors were long distance runners.
Humans hot, sweaty, natural-born runners
And as far as the pro - saturated fat stance 95 percent of all the cardiologists are not wrong. I have seen more studies on this than you know exist. I have repeatedly shown how you have misinterpreted the literature or taken it out of context .
Where are you qualifications to read primary literature? Have you ever taken a course to be able to interpret it ?
I don't buy into your ridiculous conspiracy theories you make your living off of Mr. Hale -(ex: The establishment is wrong, I am right, etc .)
