## TL;DR

A clinical trial found that cinnamon did not significantly reduce body measurements in people with type 2 diabetes.

## Contribution

This study provides new evidence on the limited efficacy of cinnamon for weight management in type 2 diabetes patients.

## Key findings

- Cinnamon reduced weight by 0.8 kg but not significantly (p = 0.11).
- No significant changes in BMI, body adiposity, or waist/hip measurements were observed.
- Results suggest cinnamon may not be effective for reducing body measurements in type 2 diabetes.

## Abstract

to evaluate the effectiveness of cinnamon (Cinnamomum verum) in reducing anthropometric measurements in individuals with type 2 diabetes.

a randomized, triple-blind, placebo-controlled clinical trial was conducted with 140 participants, divided into an experimental group (n = 71) and a control group (n = 69). The experimental group consumed 3 g/day of encapsulated cinnamon for 90 days. Anthropometric variables were measured at baseline and at the end of the study, with intra-group comparisons performed using a paired t-test.

the majority of participants were women (69.2%) with a mean age of 61 years. Reductions were observed in weight (-0.8 kg, p =0.11), body mass index (-0.36 kg/m2, p =0.16), body adiposity index (-1.02%, p =0.38), waist circumference (-3.97 cm, p =0.67), neck circumference (-0.45 cm, p = 0.68), and hip circumference (-1.83 cm, p =0.49), none of which were statistically significant (p > 0.05).

cinnamon supplementation resulted in reductions in anthropometric measurements compared to placebo, but these differences were not statistically significant.

analisar a eficácia da canela (Cinnamomum verum) na redução de medidas antropométricas em pessoas com diabetes tipo 2.

ensaio clínico randomizado, controlado por placebo, triplo cego, realizado com 140 participantes divididos em grupo experimental (n = 71) e controle (n = 69). O grupo experimental ingeriu 3 g/dia de canela encapsulada por 90 dias. Variáveis antropométricas foram medidas no início e ao final do estudo, comparadas intragrupo pelo teste t pareado.

a maioria dos participantes era composta por mulheres (69,2%), com média de 61 anos. Observou-se redução no peso (-0,8 kg, p =0,11), índice de massa corporal (-0,36 kg/m2, p =0,16), índice de adiposidade corporal (-1,02%, p =0,38), circunferência da cintura (-3,97 cm, p =0,67), pescoço (-0,45 cm, p =0,68) e quadril (-1,83 cm, p =0,49), sem significância estatística (p > 0,05).

o uso da canela reduziu medidas antropométricas em comparação ao placebo, porém sem significância estatística.
