No "lips to hips"

One of the many false assertions that foodie pseudo-scientists make is that food is absorbed essentially intact. WRONG!
Ingestion, digestion, propulsion, absorption, and defecation are process es that are focused on breaking food down into usable units--glucose, fatty acids, amino acids, and small co-factor molecules such as vitamins and minerals.
We have evolved a nutrient utilization system that is maximally flexible, so that we can consume a broad array of foods and still get what we need at the cellular level.
What goes to the hips (or belly) are excess calories of any kind, stored as adipose or fat. The key to not having this happen? Consume fewer calories than you expend!
