THERMOfit's Programs and Recipes aren't calorie controlled but more focused on a balance of Macronutrients (Carbs, Proteins, Fats) without counting anything just eating healthy for sustainability. The above video I made about the type of eating you will find in THERMOfit's Programs.

Yes, most of the recipes containing nuts can be modified. It is mostly Cashews and Almonds used in the program as flour substitutes and I have found that if you replace all Cashews with Sunflower Seeds and the Almonds with Linseeds/Flaxseeds that works well. You can even use a mix of those 2 plus Buckwheat to replace the nuts.

Where there is a nut flour used for something I recommend getting the total amount of nut meal needed and dividing that amount into 3 parts and use an equal sunflower/flaxseed/buckwheat combination.

Yes this has been designed to suit the whole family and even the hard to please. You will find these recipes are healthy versions of familiar favourites.

The reason this meal plan is 5 days rather than the full 7 is for a few reasons:
 - To account for the inevitable and occasional nights out, social events or nights off cooking without wasting food and money.
 - It is great practice to take ownership and responsibility of those 2 nights a week. If not going out, it is a great way to start a routine of finding some recipes you would like to add into your week. Doing this for just 1 or 2 nights a week will be less overwhelming and build a great habit to increase upon later.

Should you wish to increase this to 6 or 7 nights a week it is easy to do so. I suggest the following ways:
 - Choose the recipe/s to add in to your week and add the ingredients to your shopping list accordingly.
 - Some meals are more than 4 serves and create freezable leftovers. You can factor those leftovers into your weekly meal plan and enjoy those nights off cooking while also saving money.
