There are numerous possibilities in adjusting both the level and
source of fat. The following formulas could be used to
induce obesity and metabolic syndrome. Contact us to discuss
the use of these diets or one that better meets your needs (and
read below for background information).

Control Diets (for high fat
diets)
Purified control diets can be designed in several ways,
depending on what features the researcher wants to modify relative
to the high fat diet. Below are just two examples.

Diets for Diet Induced
Obesity (DIO)
Purified high fat diets used to induce obesity and
obesity-related complications such as diabetes and metabolic
syndrome typically have from 40-60% of energy derived from fat.
This flyer summarizes relevant diet details for several different
diets, and includes a table with information on the fatty acid
profile of various fat sources used in purified diets.
As a reference point, the AIN purified diets have in the range
of 4-7% fat by weight, or about 10-18% of energy from fat. Adding
fat (at the expense of carbohydrate) is done to increase the kcal
density. Diets with higher fat levels will have a greater kcal
density, since fat contains 9 kcal/g vs. 4 kcal/g for carbohydrate
or protein. The AIN-93G diet contains approx. 3.8 kcal/g, while a
typical diet with 45% kcal from fat has ~4.5 kcal/g and a diet with
60% of kcal from fat has ~5.0-5.5 kcal/g. In the formulation of a
high fat diet, it is common to adjust other nutrients (vitamins,
minerals, protein) relative to energy content.
A number of different fat sources can be used (solid fats,
oils), and diets can be designed to target a specific fat level or
fatty acid profile.
The amount and type of fat used can affect pellet quality. As
the fat level increases, pellet quality (durability) is
compromised. Some higher fat formulas are available only in
non-pelleted form. Depending on the fat source used, the
non-pelleted form could be dense and crumbly, dough-like, or
paste like.
