Abstract
Ideal body weight (IBW) equations and body mass index (BMI) ranges have both been used to delineate healthy or normal weight ranges, although these 2 different approaches are at odds with each other. In particular, past IBW equations are misaligned with BMI values, and unlike BMI, the equations have failed to recognize that there is a range of ideal or target body weights.For the first time, to our knowledge, we merged the concepts of a linear IBW equation and of defining target body weights in terms of BMI.With the use of calculus and approximations, we derived an easy-to-use linear equation that clinicians can use to calculate both IBW and body weight at any target BMI value. We measured the empirical accuracy of the equation with the use of NHANES data and performed a comparative analysis with past IBW equations.Our linear equation allowed us to calculate body weights for any BMI and height with a mean empirical accuracy of 0.5-0.7% on the basis of NHANES data. Moreover, we showed that our body weight equation directly aligns with BMI values for both men and women, which avoids the overestimation and underestimation problems at the upper and lower ends of the height spectrum that have plagued past IBW equations.Our linear equation increases the sophistication of IBW equations by replacing them with a single universal equation that calculates both IBW and body weight at any target BMI and height. Therefore, our equation is compatible with BMI and can be applied with the use of mental math or a calculator without the need for an app, which makes it a useful tool for both health practitioners and the general public.

Overweight and obesity are associated with various chronic conditions.1 These conditions are considerable health care and societal burdens, yet could potentially be averted by preventing weight gain and obesity. In a prior analysis, now almost 20 years old, Must et al2 used a nationally representative data set from 1988 through 1994 and reported the US chronic disease burden associated with body mass index (BMI), thus informing clinical practice and the priorities for cost-effective prevention s...

Objective—This report presents national anthropometric reference data for all ages of the U.S. population in 2003–2006, adding to results published previously from 1960–2002. Methods—Data are from the National Health and Nutrition Examination Survey (NHANES), a complex, stratified, and multistage probability sample of the civilian, noninstitutionalized U.S. population. Anthropometry measurements were obtained from 19,593 survey participants. The anthropometric measures included weight, height, r...

The purpose of this paper was to compare the ideal body weight (IBW) formulas and published height-weight tables for healthy adults in the United States with the body mass index (BMI) of 22 kg/m2, which is associated with lowest mortality. There are numerous formulas and published height-weight tables available to determine IBW, but there are no published studies comparing the validity of formulas with each other or comparing formulas with BMIs. Data from height-weight tables, weight for specifi...

OBJECTIVE:To provide a historical perspective on the origin and similarity of the “ideal” body weight (IBW) equations, and clarify the terms ideal and lean body weight (LBW).DATA SOURCES:Primary and review literature were identified using MEDLINE (1966–November 1999) and International Pharmaceutical Abstracts (1970–November 1999) pertaining to ideal and lean weight, height–weight tables, and obesity. In addition, textbooks and relevant reference lists were reviewed.DATA EXTRACTION:All articles i...

Abstract This paper attempts to answer five questions. (1) How should we best measure overweight? Although life insurance tables and relative weights have been used, I propose that body mass index (BMI; wt/ht 2 ) is the preferred method. It is currently used in most epidemiologic studies and can be used in clinical evaluation of individual patients. (2) What is a healthy body weight? A healthy body weight can be defined from normative population data as well as from mortality experience. The Nat...

The ideal body weight (kg) of each individual can be calculated by the following formula: ideal body mass index × the height (m) 2 , since body mass index is expressed by the body weight in kilogram divided by the height squared in meters. We investigated an ideal body mass index with respect to morbidity in 4565 Japanese men and women aged 30-59 years. Ten medical problems served as indices of morbidity: lung disease, heart disease, upper gastrointenstinal disease, hypertension, renal disease, ...

Summary Purpose Enteral and parenteral nutrition of adult critically ill patients varies in terms of the route of nutrient delivery, the amount and composition of macro- and micronutrients, and the choice of specific, immune-modulating substrates. Variations of clinical nutrition may affect clinical outcomes. The present guideline provides clinicians with updated consensus-based recommendations for clinical nutrition in adult critically ill patients who suffer from at least one acute organ dysfu...

We evaluated the presence of sarcopenia in a population of systemic sclerosis (SSc) patients, with respect to nutritional, clinical, and laboratory features. A total of 62 patients who met the ACR/EULAR 2013 classification criteria were enrolled. Sarcopenia was defined according to the Relative Skeletal Mass Index (RSMI) and hand grip strength (HGS). Body composition was assessed with the calculation of the Body Mass Index (BMI), lean body mass (LBM) and fat mass (FM). Malnutrition was evaluated...

Nutritional therapy is an elemental component of intensive care treatment. Therapeutic goals are the enteral or parenteral provision of calories, protein, electrolytes, vitamins and trace elements. Pathophysiologically, metabolism in critical illness is characterized by a catabolic stress status. This results from an underlying systemic inflammatory response and is associated with increased rate of infections, multiple organ failure and unfavourable outcome. In this article, the principles and s...

Purpose Enteral feeding intolerance (EFI) is a frequent problem in the intensive care unit (ICU), but current prokinetic agents have uncertain efficacy and safety profiles. The current study compared the efficacy and safety of ulimorelin, a ghrelin agonist, with metoclopramide in the treatment of EFI.

Summary Following the new ESPEN Standard Operating Procedures, the previous guidelines to provide best medical nutritional therapy to critically ill patients have been updated. These guidelines define who are the patients at risk, how to assess nutritional status of an ICU patient, how to define the amount of energy to provide, the route to choose and how to adapt according to various clinical conditions. When to start and how to progress in the administration of adequate provision of nutrients ...

Summary Background & aims High protein delivery during early critical illness is associated with lower mortality, while energy overfeeding is associated with higher mortality. Protein-to-energy ratios of traditional enteral formulae are sometimes too low to reach protein targets without energy overfeeding. This prospective feasibility study aimed to evaluate the ability of a new enteral formula with a high protein-to-energy ratio to achieve the desired protein target while avoiding energy overfe...
