☆☆☆☆☆Oxygen has 8 protons in the atom.
It becomes a negative ion.
Not exactly; it's true to say that all cooking oils are vegetable oils, but not all vegetable oils are cooking oils. For example, linseed oil is vegetable oil, but can't be used for cooking.
One reason people are fat is because they eat and eat and eat and don't exercise. Another reason is because some people have fast working calorie burning systems and some people have slow ones causing them to be fat.
It might be that those people that are not fat have high metabolism you eat as much as you want and not get fat.
Polysaccharides have more chemical bonds.

Short Answer:
By weight, oxygen makes up approximately 65% of the human body.
Carbon comes in second with 18% of the mass
Hydrogen adds 10% more of the mass.
These three account for 93% of the mass of the human body.
Numerically, hydrogen 63% of the total number of atoms in the human body, but it is probably closer to 63% for most people.
Accounting by Mass:
The mass of the human body is provided mostly by oxygen, carbon, hydrogen, nitrogen. Together these elements account for about 96% of the mass of a human.
Add in about a kilogram of calcium in the bones and body fluids and you are up to 97.4%. All of this depends on the particular person since water, our major component, can differ by 10% from one individual to another.
That said, typically the breakdown goes like this.
Oxygen: 65% of the mass
Carbon: 18% of the mass
Hydrogen: 10% of the mass
Nitrogen: 3% of the mass
Calcium: 1.4 % of the mass
Phosphorus 1.1% of the mass
With phosphorus, one has accounted for 98.5% of the mass of the typical human and that will change by a couple of tenths from person to person.
Accounting by Numbers:
Numerically we have nearly twice as many hydrogen atoms in our bodies as compared to all other elements combined. Specifically, hydrogen counts as 63% of our atoms by number, give or take a bit, but being so light it barely gets to 10% of our mass. Oxygen atoms count as 24% and carbon atoms are a mere 12% of the populations. Together, our three basic organic building blocks account for 99% of all the atoms in the body.
Caveat:
As was said above, the water content of the human body weight varieties between 55 to 65 % from one person to the next and being the major component changes the numbers above a little for each individual.
Summary:
Almost 99% of the mass of the human body is made up of the six elements oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.
Most of the last 1% is made up of five elements: potassium, sulfur, sodium, chlorine, and magnesium, but a tenth of a percent or so is made up of another dozen or so elements which include those recognized as essential to health such as iron, iodine and fluorine as well as beneficial trace elements like manganese, copper and zinc.
