Diet induced thermogenesis, fat oxidation and food intake following sequential meals: influence of calcium and vitamin D.

What Was Tested

Researchers studied Vitamin D, K2, Magnesium and Zinc in this randomized controlled trial publication.

The mechanisms linking dietary calcium and vitamin D to body weight regulation require confirmation.

Who Took Part

PubMed indexes the participants as middle-aged adults, both men and women.

Eleven subjects, aged (mean ± SEM) 54 ± 1.2 y and BMI 31 ± 2.4 kg/m(2), participated in a randomised within-subject, sequential meal protocol comparing a low calcium trial (LCT) to an isoenergetic high calcium trial (HCT).

Diet induced thermogenesis (DIT), fat oxidation rates (FOR), serum leptin, subjective feelings of hunger/satiety were measured at fasting and hourly over 8 h.

How the Study Was Run

The design is described as randomized and crossover.

The participants were allocated by chance, so the Vitamin D, K2, Magnesium and Zinc group and the comparison group should start out alike.

In the crossover set-up each of the participants took both Vitamin D, K2, Magnesium and Zinc and the comparison in turn, acting as their own control.

Spontaneous food intake at a buffet and over the following 30 h was recorded.

Postprandial responses, calculated as change (Δ) from baseline for each meal, were analysed by paired t-tests and 2 × 2 repeated measures ANOVA.

What Was Measured

PubMed files the paper under topics including Appetite Regulation, Calcium, Dietary, Dairy Products, Dietary Carbohydrates, Dietary Fats, Eating and Leptin.

What This Means in Plain Language

The paper is a randomized and crossover study of Vitamin D, K2, Magnesium and Zinc.

Results are reported in around 4 sentences of the abstract; we leave them to the paper itself rather than summarise them.

The publication is from 2011 (Clinical nutrition (Edinburgh, Scotland)), a journal based in England.
