A recent study showed that if children consume fewer calories per day, and walk an additional 2,000 steps, it could help them prevent weight gain.
However, the study was funded by McNeil Nutritionals, the manufacturers of the sugar substitute Splenda, and those study participants who were on a calorie-reduction program used Splenda.
The study was touted as showing the beneficial effects of calorie reduction, and the participants using Splenda and exercise controlled their weight better than those simply asked to monitor their usual levels of diet and exercise. However, neither group experienced any great changes in weight or fitness.
