Abstract
A plethora of studies to date has examined the roles of feeding-related peptides in the control of food intake. However, the influence of these peptides on the intake of particular macronutrient constituents of food - carbohydrate, fat, and protein - has not been as extensively addressed in the literature. Here, the roles of several feeding-related peptides in controlling macronutrient intake are reviewed. Next, the relationship between macronutrient intake and diseases including diabetes mellitus, obesity, and eating disorders are examined. Finally, some key considerations in macronutrient intake research are discussed. We hope that this review will shed light onto this underappreciated topic in ingestive behavior research and will help to guide further scientific investigation in this area.

Tordoff MG, Ellis HT. Obesity in C57BL/6J mice fed diets differing in carbohydrate and fat but not energy content. Physiol Behav 2022; 243:113644. [PMID: 34767835 PMCID: PMC8667181 DOI: 10.1016/j.physbeh.2021.113644] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Revised: 11/05/2021] [Accepted: 11/06/2021] [Indexed: 01/03/2023]
Abstract
To investigate the contributions of carbohydrate and fat to obesity we measured the body weight, body composition and food intake of adult C57BL/6J mice fed ad libitum with various combinations of two semisynthetic diets that differed in carbohydrate and fat but not in protein, micronutrient or energy content. In Experiment 1, involving male mice, body weights were similar in groups fed diets comprised of (by energy) 20% protein, 75% carbohydrate and 5% fat (C75-F5) or 20% protein, 5% carbohydrate and 75% fat (C5-F75). However, mice fed a 50:50 composite mixture of the C75-F5 and C5-F75 diets (i.e., a C40-F40 diet) became substantially more obese. Mice that could choose between the C75-F5 and C5-F75 diets ate equal amounts of each diet and gained almost as much weight as did the group fed C40-F40 diet. Mice switched every day between the C75-F5 and C5-F75 diets gained no more weight than did those fed either diet exclusively. In Experiment 2, male and female mice were fed chow or one of 8 isocaloric diets that differed parametrically in carbohydrate and fat content. Groups fed diets in the middle of the range (i.e., C35-F45 or C45-F35) weighed significantly more and were significantly fatter than were those fed diets with more extreme proportions of carbohydrate and fat (e.g., C75-F5, C5-F75), an effect that was more pronounced in males than females. In Experiment 3 and 4, male mice fed versions of the C40-F40 formulation gained more weight than did those fed the C75-F5 or C5-F75 formulations irrespective of whether the carbohydrate was predominantly sucrose or predominantly starch, or whether the fat was vegetable shortening, corn oil, palm oil or canola oil; the type of carbohydrate or fat had little or no impact on body weight. In all four experiments, energy intakes differed among the diet groups but could not account for the differences in body weight. These results demonstrate that the proportion of carbohydrate and fat in the diet influences body weight independently of energy content, and that the type of carbohydrate or fat has little impact on body weight. Consuming carbohydrate and fat simultaneously or in close temporal proximity exacerbates obesity.

Biochim Biophys Acta Mol Basis Dis 2017; 1863:1789-1804. [PMID: 28457799 DOI: 10.1016/j.bbadis.2017.04.022] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2016] [Revised: 04/19/2017] [Accepted: 04/25/2017] [Indexed: 12/11/2022]
Abstract
Few studies have assessed the effect of changing ratios of dietary macronutrients on fat accumulation in adipose tissue and organs such as the liver in a 3×n(n≥3) factorial design. We investigated the effects of 7 diets from a single manufacturer containing 11-58en% protein (casein), 0-81en% carbohydrates (CHO; sucrose, maltrodextrin-10 and corn starch), and 8-42en% fat (triheptanoin, olive oil or cocoa butter) in C57BL/6J mice, a good model for diet-induced obesity and fatty liver. The diets were fed for 3weeks to wild-type and hyperlipidemic male and female mice. Caloric intake was mainly determined by dietary fat. Body weight, liver lipid and cholesterol content, NFκB activation, and fat-pad size decreased only in mice fed a high-protein diet. A high dietary protein:CHO ratio reduced plasma FGF21 concentration, and increased liver PCK1 protein content and plasma triglyceride concentration. The dietary protein:CHO ratio determined hepatic expression of Pck1 and Ppargc1a in males, and Fgf21 in females, whereas the dietary CHO:fat ratio determined that of Fasn, Acaca1, and Scd1 in females. Hepatic glycogen content was determined by all three dietary components. Both hepatic PCK1 and plasma FGF21 correlated strongly and inversely with hepatic TG content, suggesting a key role for PCK1 and increased gluconeogenesis in resolving steatosis with a high-protein diet, with FGF21 expression reflecting declining cell stress. We propose that a diet containing ~35en% protein, 5-10en% fat, and 55-60en% carbohydrate will prevent fatty liver in mice without inducing side effects.

Abstract
Autism spectrum disorder (ASD) is the most commonly diagnosed neurodevelopmental disorder, with current estimates of more than 1% of affected children across nations. The patients form a highly heterogeneous group with only the behavioral phenotype in common. The genetic heterogeneity is reflected in a plethora of animal models representing multiple mutations found in families of affected children. Despite many years of scientific effort, for the majority of cases the genetic cause remains elusive. It is therefore crucial to include well-validated models of idiopathic autism in studies searching for potential therapeutic agents. One of these models is the BTBR T+Itpr3tf/J mouse. The current review summarizes data gathered in recent research on potential molecular mechanisms responsible for the autism-like behavioral phenotype of this strain.

Abstract
INTRODUCTION Decades of research have suggested that nutritional intake contributes to the development of human disease, mainly by influencing the development of obesity and obesity-related conditions. A relatively large body of research indicates that functional variation in human taste perception can influence nutritional intake as well as body mass accumulation. However, there are a considerable number of studies that suggest that no link between these variables actually exists. These discrepancies in the literature likely result from the confounding influence of a variety of other, uncontrolled, factors that can influence ingestive behavior. STRATEGY In this review, the use of controlled animal experimentation to alleviate at least some of these issues related to the lack of control of experimental variables is discussed. Specific examples of the use of some of these techniques are examined. DISCUSSION AND CONCLUSIONS The review will close with some specific suggestions aimed at strengthening the link between gustatory neural input and its putative influence on ingestive behaviors and the maintenance of body weight.
