Roux-en-Y gastric bypass (RYGB) and gastric sleeve (GS) have been associated with significant reductions in bone mineral density (BMD) and fluctuations in serum levels of calciotropic hormones. These changes pose a risk to bone health. The study assessed the short-term (12 and 24 months) effects of RYGB and GS on BMD and calciotropic hormones.

Objectives: Exposure to an obesogenic environment at critical stages of human development may lead to cardiovascular damage during early adulthood, such as left ventricular hypertrophy (LVH). The objective of this study is to investigate whether the consumption of diets with different levels of fat associated with fructose drink, introduced to newly weaned rats, leads to cardiovascular damage.
Methods: Male Wistar rats (age 21 d) were divided into the following groups: Control (C group) fed an American Institute of Nutrition 93G diet (16.
Objectives: The aim of this study was to analyze the effects of intermittent fasting (IF) on the performance of rats subjected to resistance training ladder climbs (RTLCs).
Methods: Thirty-two Wistar rats (80-d-old) were placed into one of the following four groups (n = 8/group): control (C), which were fed a standard diet with no exercise; intermittent fasting (IF) rats underwent IF for 16 h/d, fed a standard diet for a period of 8 h/d with no exercise; trained control (TC) were fed a standard diet and submitted to RTLC; and trained intermittent fasting (TIF) underwent IF for 16 h/d, fed a standard diet for a period of 8 h/d, and submitted to RTLC. Training groups completed 6-wk of RTLC (3 × /wk).
Article Synopsis
- The study examined the effects of high-fat (HF: 45% fat) and very high-fat (VHF: 60% fat) diets combined with a fructose drink on rats, comparing them to a control group on a lower-fat diet for 70 days.
- Results indicated that the HF diet caused greater weight gain, adipose tissue increases, and metabolic issues (like hyperinsulinemia) compared to both VHF and control groups.
- The findings suggest that a 45% fat diet with added sugars might more accurately replicate human obesity, challenging the assumption that higher fat intake is always worse and offering insights for better obesity treatment guidelines.
Article Synopsis
- The study examined whether a high protein diet using isolated whey protein (IWP) and strength training could enhance performance and reduce body fat in male Wistar rats without causing health issues.
- Four groups of rats were tested: two with normal protein diets (14% IWP) and two with a high protein diet (35% IWP), with half of each group undergoing strength training.
- Results showed that the high protein trained group significantly improved performance and muscle mass compared to other groups, and no harmful effects on health were observed, indicating a potential benefit for minimizing the risk of metabolic disorders.
Objectives: Isolated whey protein (IWP) can decrease body fat compared with other protein sources. The present study verified the effects of high protein diet (HD) containing IWP on several parameters of rats subjected to resistance training (RT).
Methods: Thirty-two male Wistar rats (60 days of age) were separated into four groups (n = 8/group): sedentary normoproteic (IWP 14%; SN); sedentary hyperproteic (IWP 35%; SH); trained normoproteic (IWP 14%; TN), and trained hyperproteic (WPI 35%; TH).
Background: The constant pursuit of improved athletic performance characterizes high-performance sport and the use of medicinal plants as dietary supplements is becoming widespread among athletes to enhance long-term endurance performance.
Aim: The present study evaluated the toxicity of Heteropterys tomentosa (HEHt) and its acute adaptogenic effects.
Methods: The in vitro safety profile was evaluated on CHO-k1 cells using the alamar Blue assay, at concentrations ranging from 3.
New insights into the effects of irisin levels in HIV-infected subjects: correlation with adiposity, fat-free mass, and strength parameters.

Objective: Patients infected with the human immunodeficiency virus (HIV) have an increased risk of metabolic disorders and alterations on irisin levels. Therefore, the purpose of the current investigation was to quantify the circulating irisin concentration in HIV-infected subjects under highly active antiretroviral therapy and to determine possible correlations between irisin levels with fat mass, fat-free mass, body mass index (BMI), and muscle strength.
Subjects And Methods: Cross-sectional study of 10 men (36.
Purpose: Although there is limited evidence regarding the pathophysiological effects of a high-protein diet (HD), it is believed that this type of diet could overload the body and cause damage to the organs directly involved with protein metabolism and excretion. The aim of this study was to verify the effects of HD on biochemical and morphological parameters of rats that completed a resistance training protocol (RT; aquatic jump) for 8 weeks.
Methods: Thirty-two adult male Wistar rats were divided into four groups (n = 8 for each group): sedentary normal protein diet (SN-14%), sedentary high-protein diet (SH-35%), trained normal protein diet (TN-14%), and trained high-protein diet (TH-35%).
