Thirty-six adult male Wistar rats (4 months-old) weighing an average of 460 g were randomized into four groups (9 rats per group), as follows: Test group A (low)--rats were fed an ethanol-containing liquid diet with ethanol representing 22% of total caloric value; Control group A--rats were fed a pair-fed control diet (ethanol replaced by
isocaloric amounts of carbohydrate); Test group B (high)--rats were fed an ethanol-containing liquid diet with ethanol representing 36% of total caloric value; and Control group B--rats were fed a pair-fed control diet (ethanol replaced by
isocaloric amounts of carbohydrate).
If someone eats exactly the number of calories spent, that individual is on an "
isocaloric diet" and the person's weight remains stable.

Isocaloric high-protein and high-carbohydrate diets in energy restriction achieve similar weight loss, but diets with a higher protein-carbohydrate ratio achieve greater loss of fat to lean tissue.
(20) Indeed, a recent study with obese males revealed
isocaloric substitution of a diet high in MUFA resulted in weight loss compared with a diet rich in saturated fatty acids.
The control group of 105 patients received an
isocaloric, isonitrogenous nutritional supplement without EPA.
In this experiment we examine ethanol teratogenesis in NSA mice by exposing pregnant dams to either 5.8 g/kg ethanol or an
isocaloric amount of maltose-dextrin on day 9 of pregnancy.
Isocaloric balanced protein supplementation in pregnancy.
For example, rats given a simultaneous choice between responding to sweetened alcohol or an
isocaloric non-drug nutrient, which provides the same number of calories as alcohol (e.g., Polycose), worked harder to maintain alcohol intake than to maintain intake of the
isocaloric nutrient when bar press response requirements were increased.
Experimental diets were
isocaloric (4.35-4.38 kcal [g.sup.-1]), casein-based rations and were formulated by mixing specified quantities of 4% and 16% crude protein diets (United States Biochem, Cleveland, Ohio).
The
isocaloric substitution of ethanol for carbohydrates decreases body weight (Pirola and Lieber, 1972).
Glycemic effects of intensive caloric restriction and
isocaloric refeeding in non-insulin-dependent diabetes mellitus.
Diets were formulated isonitrogenic and
isocaloric according to the recommendations of NRC (1994).
