As the Bodytrim shakes are Meal Replacements they do need to contain a certain amount of energy/calories so as to provide the body with some sustenance. In fact, legally there is a certain amount of calories a product must contain for it to be labelled and sold as a ‘Formulated Meal Replacement’.
Calories come from protein, carbohydrates (includes sugar), fat and alcohol. The Bodytrim shakes do not contain alcohol, so to make up the calories required to produce a meal replacement shake we need to utilise and find a balance of protein, carbohydrates and fats.
As you have found, most- if not all formulated meal replacement products do contain a higher amount of carbohydrates and sugars, and if they didn’t there would need to be more calories coming from protein and/or fats (the protein and/or fat content would be higher instead). Too much fat is not ideal and the same goes for protein.
In terms of the Bodytrim shakes, the milk ingredients Whole Milk Powder, Skim Milk Powder and Whey Protein Concentrate each contribute sugar in the form of lactose (naturally occurring milk sugar). The majority of sugars in the Bodytrim shakes is coming from these milk ingredients rather than added sugars, although there is a small amount of added sugar in the formula also.
I like your thinking on the Erythritol! Erythritol is a low calorie sweetener, so unfortunately the addition of this as a sweetener will not do much to contribute to the energy content of the product. We will definitely pass your suggestion onto our Product Development Team though as perhaps there may be another way around this.
