Starvation response in animals (including humans) is a set of adaptive biochemical and physiological changes, triggered by lack of food or extreme weight loss, in which the body seeks to conserve energy by reducing metabolic rate and/or non-resting energy expenditure to prolong survival and preserve body fat and lean mass.
Lipid metabolism is often considered the digestion and absorption process of dietary fat; however, there are two sources of fats that organisms can use to obtain energy: from consumed dietary fats and from stored fat. [5] Vertebrates (including humans) use both sources of fat to produce energy for organs such as the heart to function. [6]
The digestion products consisting of a mixture of tri-, di- and monoglycerides and free fatty acids, which, together with the other fat soluble contents of the diet (e.g. the fat soluble vitamins and cholesterol) and bile salts form mixed micelles, in the watery duodenal contents (see diagrams on the right).

Food fat is dispersed by the action of bile into smaller units called micelles. The breaking down into micelles creates a much larger surface area for the pancreatic enzyme, lipase to work on. The breaking down into micelles creates a much larger surface area for the pancreatic enzyme, lipase to work on.
Some foods, like ice cream cones, don't require any special equipment to get to the good stuff, but you'd be hard-pressed to finish a whole cone without at least some very sticky fingers.

The foods within the bland diet are lower in fiber and fat, while also having a more neutral flavor and smell. These include:, Lean proteins prepared with little to no fat and with mild seasoning.
The thermic effect of food is the energy required for digestion, absorption, and disposal of ingested nutrients. Its magnitude depends on the composition of the food consumed: Carbohydrates: 5 to 15% of the energy consumed [7] Protein: 20 to 30% [7] Fats: at most 5 to 15% [8]
