The liquid diet, the baby food diet, the raw food diet, people have gone to some pretty extreme lengths to lose weight, but even those who don't follow the craziest diet trends and stick with plain old healthy eating regimens, could be doing it wrong. Yes, one dietician is shedding some light on these healthy food mistakes by posting identical photos of the same healthy recipe but with an upward difference of around 300 calories.

The nutritionist, Paula Norris, has captioned the collection on Instagram 'Spot The Difference' and trust us - you can't. Along with the high calorie and low-calorie photos, she writes out the calorie saving recipes and general healthy diet tips such as portion control, focusing on healthy oils and replacing starchy carbs with nutritious foods.

For Norris, the key is attainability, writing on her page: "Ever since I studied Dietetics, I haven't bothered with drastic diet changes to achieve goals because I know how short term, unsustainable and depressing they are. Changes I make are small, almost unnoticeable, and spread across days and weeks. Decreasing the serving size of energy-dense foods and increasing portions of low energy density but high in nutrition value foods has been key for me. A lot of small changes can add up!"
