The outcomes include weight, height/length, adiposity indices, and/or risk of overweight and/or obesity. The risk of bias was evaluated with instruments for each respective design (Cochrane’s Risk of Bias 2.0 and RoB-NObS). A meta-analysis of five cohort studies was performed.

In total, 21 studies from 27 publications were included, of which five were RCTs and 16 were cohort studies. The RCTs found generally null effects of high-protein intake in infants on weight gain, nor that lower protein diets negatively affected growth. All included RCTs had some concern regarding the risk of bias and were limited by small sample sizes. Total protein intake and BMI were assessed in 12 cohorts, of which 11 found positive associations. The meta-analysis revealed a pooled effect estimate of 0.06 (95% CI 0.03, 0.1) kg/m<sup>2</sup>&nbsp;BMI per one E% increment in total protein (<em>I</em><sup>2</sup>&nbsp;= 15.5). Therefore, the evidence for a positive relationship between total protein intake and BMI was considered&nbsp;<em>probable</em>. Furthermore, there was&nbsp;<em>probable</em>&nbsp;evidence for an association between higher intake of animal protein and increased BMI. There was&nbsp;<em>limited, suggestive</em>&nbsp;evidence for an effect of total protein intake and higher risk of overweight and/or obesity, while no conclusions could be made on the associations between animal vs. plant protein intake and risk of overweight and/or obesity.</p> <p style="color: #000000; font-family: 'Times New Roman'; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;"><strong><em>Discussion:</em></strong>&nbsp;In healthy, well-nourished children of Western populations, there is probably a causal relationship between a high-protein intake in early childhood (≤ 18 months) – particularly protein of animal origin – and higher BMI later in childhood, with consistent findings across cohort studies. A lack of RCTs precluded a stronger grading of the evidence.</p> 2022-02-21T12:55:34-08:00 Copyright (c) 2022 Erik Kristoffer Arnesen, Birna Thorisdottir, Christel Lamberg-Allardt, Linnea Bärebring, Bright Nwaru, Jutta Dierkes, Alfons Ramel, Agneta Åkesson https://foodandnutritionresearch.net/index.php/fnr/article/view/7974 <em>Lactobacillus plantarum</em> FRT4 alleviated obesity by modulating gut microbiota and liver metabolome in high-fat diet-induced obese mice 2022-05-09T22:25:15-07:00 Hongying Cai caihongying@caas.cn Zhiguo Wen wenzhiguo@caas.cn Lulu Zhao zhll2014@yeah.net Dali Yu poseidon788@hotmail.com Kun Meng mengkun@caas.cn Peilong Yang yangpeilong@caas.cn <p style="color: #000000; font-family: 'Times New Roman'; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;"><strong><em>Background</em>:</strong>&nbsp;Obesity has become a global epidemic recognized by the World Health Organization.

Calorie restriction (CR) is a safety and effective life intervention to defend against obesity. Short-term moderate CR may be a more favorable strategy against this pathology. However, the mechanisms behind the effects of CR remain to be clarified. Increased energy expenditure in the liver and brown adipose tissue could potentially be manipulated to modulate and improve metabolism in obesity. Moreover, nicotinamide adenine dinucleotide (NAD)-dependent deacetylase sirtuin-1 (SIRT1) and AMP-activated protein kinase (AMPK) are well-characterized metabolic modulators. We aim to explore the anti-obesity effects of short-term moderate CR by improving energy metabolism via the SIRT1/AMPK pathway in white adipocytes and liver in a mouse model of obesity.</p> <p style="color: #000000; font-family: 'Times New Roman'; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;"><strong><em>Methods</em></strong>: Male C57BL/6 mice were randomized into two groups receiving either a standard or a high-fat diet (HFD) for 8 weeks to induce obesity. The HFD-induced obese mice were further randomized into two groups: HFD group or CR group (received 75% of the food eaten by HFD group). Their energy metabolism, white adipose tissue (WAT) contents, hepatic fat deposition, the expression of AMPK, SIRT1, peroxisome proliferators γ-activated receptor coactivator-1α (PGC-1α), nuclear factor kappa B (NF-κB), endothelial nitric oxide synthase (eNOS) in WAT, and hepatic tissues were determined.</p> <p style="color: #000000; font-family: 'Times New Roman'; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;"><strong><em>Results</em></strong>: After 4 weeks, body weight, total serum cholesterol, fasting blood glucose, and insulin levels were significantly lower in the CR group.

At the end of experiment, glucose tolerance test and insulin tolerance test were performed; the levels of lipids and oxidative stress-related factors in the serum and skeletal muscle were detected using chemistry reagent kits; lipid accumulation in skeletal muscle was observed by oil red O staining; the expressions of muscular glucose and lipid metabolism associated proteins were measured by Western blotting.</p> <p style="color: #000000; font-family: 'Times New Roman'; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;"><strong><em>Results</em>:</strong>&nbsp;Sesamol decreased the body weight and alleviated obesity-associated metabolism syndrome in middle-aged mice, such as glucose intolerance, insulin resistance, dyslipidemia, and oxidative stress. Moreover, muscular metabolic disorders were attenuated after treatment with sesamol. It increased the expression of glucose transporter type-4 and down-regulated the protein levels of pyruvate dehydrogenase kinase isozyme 4, implying the increase of glucose uptake and oxidation. Meanwhile, sesamol decreased the expression of sterol regulatory element binding protein 1c and up-regulated the phosphorylation of hormone-sensitive lipase and the level of carnitine palmityl transferase 1α, which led to the declined lipogenesis and the increased lipolysis and lipid oxidation. In addition, the SIRT1/AMPK signaling pathway was triggered by sesamol, from which it is understood how sesamol enhances glucose and lipid metabolism.</p> <p style="color: #000000; font-family: 'Times New Roman'; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;"><strong><em>Conclusions</em>:</strong>&nbsp;Sesamol counteracts on metabolic disorders of middle-aged alimentary obese mice through regulating skeletal muscle glucose and lipid metabolism, which might be associated with the stimulation of the SIRT1/AMPK pathway.</p> 2022-03-17T02:55:46-07:00 Copyright (c) 2022 Min-Min Hu, Ji-Hua Chen, Quan-Quan Zhang, Zi-Yu Song, Horia Shaukat, Hong Qin https://foodandnutritionresearch.net/index.php/fnr/article/view/7923 Aged green tea reduces high-fat diet-induced fat accumulation and inflammation via activating the AMP-activated protein kinase signaling pathway 2022-03-10T02:38:47-08:00 Ruohong Chen chenruohong@tea.gdaas.cn Xingfei Lai laixingfei@tea.gdaas.cn Limin Xiang liminxiang2021@126.com Qiuhua Li liqiuhua@tea.gdaas.cn Lingli Sun sunlingli@tea.gdaas.cn Zhaoxiang Lai laizhaoxiang@tea.gdaas.cn Zhigang Li lizhigang@tea.gdaas.cn Wenji Zhang zhangwenji@tea.gdaas.cn Shuai Wen wenshuai@tea.gdaas.cn Junxi Cao junxic@126.com Shili Sun sunshili@gdaas.cn <p style="color: #000000; font-family: 'Times New Roman'; font-size: medium; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;"><strong><em>Background:</em></strong>&nbsp;Obesity is a global public health concern and increases the risk of metabolic syndrome and other diseases.

Real time quantitative PCR results showed that CLA increased hepatic inflammation and intestinal permeability in the WT mice, while it significantly decreased the mRNA expression of liver TNF-α, IFN-γ, and IL-1β and markedly ameliorated intestinal tight junction proteins in the OB mice. The gut microbiota testing indicated a higher abundance of beneficial bacteria (e.g.,&nbsp;<em>Lachnoclostridium</em>,&nbsp;<em>Roseburia</em>,&nbsp;<em>Dubosiella</em>,&nbsp;<em>Oscillibacter</em>, and&nbsp;<em>Anaerostipes</em>) and a lower abundance of pro-inflammatory bacteria (e.g.,&nbsp;<em>Tyzzerella</em>&nbsp;and&nbsp;<em>Alistipes</em>) in the OB-CLA group than those of the OB group.
