Portion Sizes

Portion sizes are often mentioned as one of the most confusing parts of getting the hang of this whole healthy eating eating thing. While everyones required calorie intake varies and along with that so does portion sizing, it's still a good idea to have a visual understanding of common portion sizes.
​
Your meal plan will have the required portion size for your specific goals and weighing food is always going to be the most accurate way to reach that portion size but not everyone is going to have the time or desire to do that. For most of us, weighing food is not the most sustainable method of healthy eating. With that in mind, the below will give you an idea of portion sizes without weighing food and instead using standard every day items as a comparision.
​
You can then double or halve the amounts as required based on your meal plan.
