- Foods rich in harina blanca: panes blancos, galletas, pasteles, botanas (snacks);
- Foods rich in sugars: chocolate, sweets, fruit marmalade, ice cream, syrups;
- Drinks: refreshments, industrialized yokes, energy drinks, coffees or tés con azúcar;
- Others: white rice, porridge, pasta and fast food;
- Foods rich in fatsuch as sausages, salsas, tocino, quesos amarillos, whole milk and derivatives, fried foods, frozen foods such as pizzas and lasañas.

Small meals can be made by consuming a portion of fruit; a natural yoghurt that can be complemented with 1 cup of oatmeal, fruits and/or oilseeds such as nueces, cacahuates and almonds; 3 squares of chocolate at 70%; 1 cup of sugar-free gelatin; puffed rice tortillas with queso blanco; homemade banana and cinnamon ponquecitos; chia pudding with fruit.
