THE BEST DIET FOR YOU!
Updated: Feb 10
So over the Years I have been constantly asked 'What is the best diet'? 🤔
Do I recommend Keto?', 'Is IIFYM better than Clean Eating?', 'What about Vegan'?
In truth, most of the said diets appear to work for most people.
Part of the problem however is there is no one size that fits all generally speaking. One dietary lifestyle for one individual may be a complete disaster for another individual.
So what is the BEST diet? 🤔🤔
To put it simply whilst this topic is incredibly nuanced it is also very much context dependent i.e. Goals, individual situation, Health etc.
However, before we can decipher which diet may be right for you, let's re-cap some of the most popular diets and how they fare up alongside one another.

VERDICT? 🤔
Ok, so every diet has a 'gimme' and a 'gotcha'.
Changing from one diet to another i.e. high carbs to low carbs or high fat to low fat, tends to have less of a positive effect on our metabolic health and biomarkers for the most part[2-3,6-11].
Following rigid dietary practices whilst removing the thought process and emotion can also be less than perfect as micronutrient quality intake & healthy eating practices also come into play [4,5].
Whilst deciphering which dietary lifestyle (Energy In) is best, Physical activity (Energy Out) demands will also play a key role going forward.
Physical activity and exercise are always great tools and a useful weight loss strategy through total energy (calorie) expenditure alongside appetite regulation[26].
However, there will always be some sort of trade-off i.e. learning required in order to successfully adhere to any dietary lifestyle long term.
The key is Education.
If you are constantly jumping around in search for 'the best diet',
The question isn't "What is the best diet?", but rather "What can I stick to long term?".
Make the informed decision before making the switch!
