Lipids are also not poison.They are essential to cell structure as they form the majority of the cell membrane, which is a key determinant of cellular differentiation. The brain is 70% fatty tissue--making all of us "fat heads".
It's not lipids per se that are the problem--it is the amount and kind of lipids we ingest. Being more than 30% of calories, saturation, and the "trans" isomeric structure all can cause metabolic problems (especially atherosclerosis). Stored fats (adipose tissue), which are the second layer of energy after glucose and stored glycogen, are highly efficient in that they contain about 7 calories per gram, whereas glycogen and protein only contain 4. This means, in fact, that more calories must be expended to utilize it as energy.
And, unfortunately, foodie lies about special "fat burning foods" are just that--lies.
Once again the issue is balancing intake with output, and in the case of lipids making sure to avoid saturated and trans fats, as well as excess calories!
