The goal of this intervention study is to evaluate the efficacy in subjects with overweight or obesity of protein bars consumption. The main questions it aims to answer are: * Does the regular consumption of these protein bars help to loose weight? * Does the regular consumption of these protein bars help to improve the osteoarticular health? Participants will be asked to follow the indications of consumption of the bars togather with healthy nutritional advice during 16 weeks. Researchers will compare exparimental Versus placebo groups to see if weight is lost in similar or different ways.
The intervention is designed to evaluate the efficacy of the consumption of a protein bar vs placebo on weight control and osteoarticular health. For this purpose, a total of 102 subjects will be randomised to either the experimental group or the placebo group, the only stratification performed will be acording to sex.
