Michael Eades: New Hypothesis of Obesity

Where does the topic of exercise fit into this thread?

It belongs! I think most of our weight is the result of how much we eat. Exercise has some calorie burning benefits, but in the 5 to 10% range, you can't exercise away fat without cutting calories. Exercise has lots of other non-weight related benefits.

Ed was in trouble. He forgot his wedding anniversary. His wife was really angry. She told him "Tomorrow morning, I expect to find a gift in the driveway that goes from 0 to over 150 in less than 6 seconds
AND IT BETTER BE THERE".
The next morning Ed got up early and left for work. When his wife woke up, she looked out the window and sure enough there was a small box gift-wrapped in the middle of the driveway. Confused, the wife put on he robe and ran out to the driveway, brought the box back in the house.
She opened it and found a brand new bathroom scale.
Funeral services for Ed have been scheduled for Friday.​
 

I'm with Alligatorob on this. In my experience, there are lots of benefits to exercise, but It plays a smaller role in weight loss than a lot of people believe.

Agree. We ought to be looking at all this in terms of total fitness, which encompasses exercise, diet, mental health and other components. One part supports the other.

Certainly. Exercise uses up what we run on - in fact what every living thing runs on - glucose. Not fat. That's why 100% of carbohydrate we eat is converted to glucose.
We store a small amount of fat in case there is no food available, but it's not our main source of energy. Unfortunately, many people think the more they exercise, the more weight they'll lose.

Every living thing does not run on glucose. Even our primate relatives, for example, eat prodigious amounts of plant matter, containing glucose, fructose and cellulose. They have huge guts with large colonies of bacteria that ferments the cellulose into SCFA (short chain fatty acids - particularly butyrate). They run mostly on butyrate. Glucose and fructose are minor sources of energy.

Ruminants eat exclusively grasses and related small shrubs which are virtually all cellulose. They, too, have a huge digestive system consisting of 4 separate chambers. One contains a large colony of cellulose fermenting bacteria that ferments the cellulose into SCFA - almost entirely butyrate.

That's why 100% of carbohydrate we eat is converted to glucose.

Please watch the video by Dr Paul Mason I linked above. It's also here. Carbs are glucose. The more carbs you eat the more glucose gets converted to fat, both in adipose cells and the liver.

Humans can store huge amounts of fat as the current epidemic of obesity demonstrates beyond doubt. One can store so much fat that mobility becomes impossible without a powered wheel chair.

but it's not our main source of energy.

Our species evolved over several million years with animal fat as our main source of energy. It's only been within the last 8-10K years that plant based carbs have become common. Much to our detriment. Prior to the advent of the Holocene, our ancestors lived most, if not all, of their lives in ketosis - which is the normal and healthy state of human metabolism - running on fatty acids and ketones derived from them.

See this for a relatively non-technical discussion, with references if you care to investigate further.

Carnivorous animals that mainly eat meat have a digestive system that converts more of their protein to glucose for energy. Same with Ruminants that eat mainly plant matter.

Yes, Carbs are glucose - as I stated. 100% of carbs are converted to glucose. Carbs that aren't used get converted to fat. Depends on both how much carbs we eat and how active we are. Of course, if we eat excess carbs AND don't use them for energy, we will store much of it as fat.
