If someone eats more calories than they burn, then they will put on weight, as I understand.
But what if a person eats a lot of calories but zero fat? Or zero saturated fats and trans fats?
Would the person then put on weight or not?
That question is based on the idea - and I don't know if this is true or not - that people put on fat by eating too many calories because the body burns other stuff that it extracts from food before burning the fat from food.
So question 2:
Is it true that that is the reason the body accumulates fat - because the body uses other things as energy before using fat?
That first question is also based on the idea - and again, I don't know if this is true or not - that the body cannot convert something that is not fat, into fat. Something that is not fat cannot be changed into fat in the body.
Is it true that the body cannot convert something that is not fat into fat? Rather, the body simply accumulates fat while burning other things?
And question 4:
Would a diet consisting only of fruit, vegetables, nuts, seeds, honey, eggs, and fish be effective for a person to lose weight even if the person eats a lot of food - so long as they only eat those things?
