Why is it that someone can lose 15 pounds following a weight loss nutrition plan, but another person doesn’t lose any weight when following that same plan? And how is it possible that a vegan diet can leave one person filled with energy and another feeling weak?

And why are there so many different types of diets? Paleo, gluten-free, raw-food, low-carb, vegan, vegetarian, pescatarian, ketogenic, Dietary Guidelines for Americans… It seems like every day we’re hit with a new discovery regarding that food and this diet. And every day I’m even more confused about what I should and should not be eating.

But I have realized one thing…

There is no “one size fits all” diet.

Nutrition is a science. And science is never perfect or finished. 

When it comes to nutrition, two contradictory theories can both be proven true. What works for one does not work for everyone. A diet that’s perfect for you and your unique body may negatively affect someone else.

We’re individuals. We all have different bodies that function in their own ways. And there are so many other factors and variables that affect how something may impact us. Age, lifestyle, environmental factors, gender, ethnic background, size, unknown health concerns… They all play a role. So don’t beat yourself up if certain drugs and herbs work for your friend, but they don’t work for you.

This is why I recommend using personalized nutrition plans as opposed to general ones. There are studies that prove the beneficial effects of using personalized nutrition plans. (1, 2)

And you don’t need to follow someone else’s guidance. You can create your own nutrition plan. Research and try different foods. Examine and record how they make you feel. You’ll see that some food energizes you and some cause diarrhea. Some foods will enhance your memory and focus and others will make you feel weak.

Listen to and trust your body. It will guide you to, and show you, the foods that are best for you.

Also, don’t get stuck on one particular nutrition plan. What works for you now, may not work for you later. Just continue to trust your intuition. 

And always remember that what works for someone else may not work for you.
