Weight Reduction Effect of Puerh Tea in Male Patients with Metabolic Syndrome

Abstract

Puerh tea has been proposed to promote weight loss and favorably modify glucose, insulin and blood lipids. This study tested the effect of daily Puerh tea consumption for 3 months on weight and body mass index (BMI), and select metabolic parameters. The effect of daily Puerh tea intake on weight, BMI and changes in glucose, HbA1c and lipids was evaluated in patients with metabolic syndrome. The patients (N = 70) were randomized into two groups: those taking Puerh tea extract capsule (333 mg Puerh tea extract) three times a day and those taking a placebo tea for 3 months. There was a decrease in body weight of 1.3 kg in the Puerh tea group (p = 0.077) versus 0.23 kg in the placebo arm (p = 0.186). There was also a slight decrease in BMI 0.47 kg/m(2) in the Puerh tea group (p = 0.076) versus 0.09 kg/m(2) in the placebo arm (p = 0.185), suggesting a trend of weight change, but without statistical significance. Subgroup analysis of the male patients demonstrated statistically significant improvements in body weight reduction (p = 0.004) and BMI (p = 0.004). However, the change in other metabolic parameters (cholesterol or triglyceride) or HbA1c was not statistically significant. Intake of Puerh tea for 3 months was associated with a slight reduction in body weight and BMI, especially in the male patients. Therefore, daily Puerh tea consumption may be an alternative choice to modify body weight.

Tea Consumption and Longitudinal Change in High‐Density Lipoprotein Cholesterol Concentration in Chinese Adults

“…Similar results were observed in some12, 31 but not all previous studies 30, 32. Total/HDL cholesterol reflects the balance between the cholesterol carried by atherogenic and protective lipoproteins 33.…”

“…However, in the participants at highest cardiovascular disease risk, a nonsignificant trend was observed for a positive association between tea consumption and HDL‐C concentrations, whereas no such trend was observed in the healthy participants 7, 8, 9. Trials conducted in participants with chronic conditions including obesity, hypertension, or other metabolic symptoms and durations >12 weeks reported significant increases in HDL‐C concentrations resulting from tea consumption 11, 13, 29, 30. Consistent with those data, in the current study we examined the long‐term effects of tea consumption on HDL‐C concentrations and found a more pronounced association between higher tea consumption and slower decreases in HDL‐C concentration over a 6‐year period in individuals aged ≥60 years or at elevated risk of developing metabolic syndrome.…”

Effects of dietary polyphenols on metabolic syndrome features in humans: a systematic review

“…As reported in Table , numerous clinical interventions have investigated the effects of polyphenol‐rich intake on anthropometric variables, weight, body mass index (BMI), waist circumference and body fat mass in MetS subjects. Clearly, clinical studies pointed towards significant beneficial effects of green tea on BMI and waist circumference . In a study by Basu et al , 35 MetS subjects were randomly assigned to three groups : control, green tea (beverage) and green tea extract given for 8 weeks.…”

Effect of the herbal medicines in obesity and metabolic syndrome: A systematic review and meta‐analysis of clinical trials

“…A significant decrease in concentration of C‐reactive protein was seen by I. gabonensis (Ngondi et al, ), pomegranate (Hosseini et al, ), Palmaria palmata (Allsopp et al, ), puerh tea (Chu et al, ; Yang et al, ), Opuntia ficus‐indica (Godard et al, ), cardamom (Kazemi et al, ), Salba‐chia ( S. hispanica L.; Vuksan et al, ), and the combination red orange, grapefruit, sweet orange, and guarana (Dallas et al, ; Figure ).…”
