Excess weight and obesity are widespread issues these days, considering that around 40% of the global adult population is overweight and 13% is classed as obese1.

Despite all the efforts that have been done to reduce it, obesity prevalence has nearly tripled during the last 40 years1.
The fundamental cause of excess weight is the imbalance between the calories consumed and the calories expended that comes with the increased consumption of energy-dense foods, and the reduction of physical activity due to the increasingly sedentary nature of many forms of work, new modes of transportation, and urban lifestyle1.

Therefore, the main strategies in order to restore the balance between calories consumed and calories expended would be to consciously create opportunities for a more active lifestyle and a healthy diet. But, as easy as it might sound, there are many people who struggle to make the right food choices, often due to the lack of time, the need to eat outside home, the increased portion sizes being served and the availability, convenience and palatability of high-energy but low-nutrient dense food2-5.

Within this context, Meal Replacements for weight control can be an innovative and practical tool, especially for those to whom healthy food choices might represent a challenge.
