To gain weight, it is enough to maintain a calorie surplus and follow a diet high in protein and complex carbohydrates. We use proven, working formulas for calculating calories in our meal plan, and the amount of food indicated in the plan is enough for proper and healthy weight gain.
You can gain weight just by following the plan without adding protein supplements, but we can also offer adding protein shakes to the plan. If they are not shown as a first meal, you can use the Swap function (for the snack meals) and choose a protein shake/bar from the proposed list of replacements.
In addition, protein powder is included in some dishes as one of the ingredients (mainly breakfasts and snacks: you can find a lot of protein cereals and protein pancakes in the list of dishes, which you can also see using the Swap function).
