They vary from individual to individual but are pretty detrimental towards achieving your fitness goal; the key being finding what works best for you.
Do you like numbers? Do you like simplicity? Do you like to be in control? Do you like time-efficiency? Do you like variation?
These are all important questions to ask yourself when making positive changes to your diet. Two years ago when I began my fitness journey, I would eat what I considered 'healthy'. My diet consisted of the usual suspects; salads, fruit, no carbs with the occasional chocolate binge.
After bouncing from one restriction to another fad I began to learn that no food can be considered 'heathy', but instead the diet it is contained within. It was then that realised I was focusing too much on what I thought I should be doing rather than what works for me personally.
For me, I have discovered that I like numbers and to be in control which is why I track my daily food intake on the My Fitness Pal app. I like to weigh my oats in the morning and my rice at night. Tracking holds me accountable, keeps me motivated and also educates me on what I am putting in my mouth. Perfect.
What important to understand is that this doesn't work for everyone. Does documenting every snack, meal or alocoholic beverage sound like too much work? Then don't do it! Use portion control and food prep to keep you in check.
Does the thought of drinking a protein shake scare you? Then don't drink them! Up your protein intake by basing every meal you eat around a source of protein. Think chicken stir fry, turkey curry, salmon bagels...
It's easy to lose sight on personal preference when making a change in your eating habits - don't force yourself into restrictive eating plans which aren't compatible with you. Remember - if your diet makes you miserable, then you are doing it wrong.
