“…Results from validation studies demonstrate that BIA routinely overestimates lean mass by 5-10% (15,16), when compared to DXA. These systematic errors in accuracy may therefore partly explain why lean mass findings differed between studies.…”

Objective: Alternate day fasting (ADF; 24-h feeding/24-h 25% energy intake at lunchtime), is effective for weight loss, but diet tolerability is questionable. Moving the fast day meal to dinnertime, or dividing it into smaller meals, may improve tolerability. Accordingly, this study compared the effects of ADF with three meal times on body weight and heart disease risk. Methods: Obese subjects (n 5 74) were randomized to 1 of 3 groups for 8 weeks: 1) ADF-L: lunch, 2) ADF-D: dinner, or 3) ADF-SM: small meals. Results: Body weight decreased similarly (P < 0.001) in all groups (ADF-L: 3.5 6 0.4 kg, ADF-D 4.1 6 0.5 kg, ADF-SM 4.0 6 0.5 kg). Reductions (P < 0.001) in fat mass and visceral fat were also comparable. Plasma lipids remained unchanged, and low density lipoprotein (LDL) particle size increased (P < 0.05) in all groups (1.3 6 0.5 Å ). Systolic blood pressure decreased (P < 0.05) by ADF-SM only. Fasting glucose, insulin, and HOMA-IR remained unchanged. Conclusions: Thus, allowing individuals to consume the fast day meal at dinner or small meals produces similar weight loss and cardio-protection as consuming the meal at lunch. This flexibility in meal timing may increase tolerability and long-term adherence to ADF protocols.

“…By means of multi-electrode configurations placed in different parts of the body, impedance measurements of the different segments can be made and local fluid distribution can be estimated. Using an eight-electrode SEG-BIA with three different frequencies (5, 50 and 250 kHz), Shafer et al (2009) analyzed 132 adults exhibiting a large range of body mass indexes (normal, overweight and obese) and found that body fat percent (BF%) can be accurately estimated in subjects classified as normal and overweight, while a significant overestimation was found in subjects classified as obese. Eight electrodes around the abdominal surface were used with SF-BIA at 50 kHz by Yoneda et al (2007) to estimate the visceral fat volume.…”

Abstract. Electrical impedance spectroscopy (EIS), in which a sinusoidal test voltage or current is applied to the sample under test to measure its impedance over a suitable frequency range, is a powerful technique to investigate the electrical properties of a large variety of materials. In practice, the measured impedance spectra, usually fitted with an equivalent electrical model, represent an electrical fingerprint of the sample providing an insight into its properties and behavior. EIS is used in a broad range of applications as a quick and easily automated technique to characterize solid, liquid, semiliquid, organic as well as inorganic materials. This paper presents an updated review of EIS main implementations and applications.

“…The region of the trunk represents ~50% of the body fat-free mass but only ~10% of body resistance. In contrast, one arm and one leg comprise ~25% of the fat-free mass and up to ~90% of total body resistance [18,19]. Those proportions can be explained by virtue of the nature of the regression equations used in bioimpedance analysis, where body parts with smaller crosssection areas make a dominant effect on resistance.…”

Current guidelines do not recommend bioelectrical impedance analysis (BIA) in patients with implanted cardiac devices. There is no data on the influence of such devices over the parameters assessed by BIA. We aimed to assess the influence of cardiac devices on the parameters assessed by BIA as well as to evaluate the likelihood of electromagnetic interference of BIA in patients with implanted cardiac devices. Sixty-two consecutive patients over 18 years of age who underwent single (PM) or multisite (CRT) pacemaker or defibrillator (ICD) implantation were included. Body composition assessment was done using a single frequency device, on both right and left sides, before and after cardiac device implantation. During BIA analysis after device implantation, we did real-time telemetry to assess electromagnetic interference. Patients were 67+14 years old and 51.6% male. PM was implanted in 52 patients (83.9%), ICD in 7 (11.3%), ICD with CRT in 2 (3.2%) and CRT in 1 (1.6%). During real-time telemetry, there was no electromagnetic interference including interruption of telemetry. Default device programming did not change after BIA assessment. After surgery, resistance and fat mass were smaller, while cellular mass, fat-free mass, metabolic rate and total body water/ body weight increased, on right and left sides measurements. We concluded that decreased resistance and related parameters after device implantation were probably influenced to a change in hydration status, regardless of the implanted device. Bioimpedance analysis is safe in patients with an implanted cardiac device.
