What Should I Eat?

What should I eat? One of the most frequent questions I get asked by my clients.  Whether it be to improve digestion, performance or body composition, most people are looking for some sort of guidance around the question ‘What should I eat?’.  This often comes from the belief that the answer is contained within a book, a course or inside the brain of a dietitian, nutritionist or health coach.  If they can just figure out whether they should be eating ‘plant-based', ‘paleo’, ‘Mediterranean’, or 'carnivore', all of their food issues would be resolved.

But really, the answer to ‘What should I eat?’ is ‘What works for you.’  I know that’s not a sexy answer.  It certainly doesn't sell any diet books. But the fact of the matter is that we’re all different.  While one person may thrive on a vegan diet, another may need something with more animal protein.  Think of all of the different environments around the world where humans have evolved over thousands of years. It should come as no surprise that in one geographic or cultural area we could evolve to thrive on a dietary pattern that might look very different from another.

So how do we answer the question, ‘What should I eat?’.  I come from a position that there are no bad foods. Some foods are just better than others.  There are good foods, better foods and best foods.  How do we know what the better and best choices are for us?  There are the three characteristics I look at:

1) How processed is the food?

There are a number of reasons why, regardless of the nutritional strategy you choose, whole foods are a better choice than over-processed foods.  Here are just a few:

  • Whole foods tend to have a lot more dietary fibre which keeps you ‘regular’.  Dietary fibre also helps to keep you fuller, longer so you don’t overeat. Fibre reduces blood sugar highs and lows and their negative side effects.  And lastly, fibre has been associated with reducing your risk for colon cancer.

  • Whole foods tend to have more of the vitamins and minerals that our bodies need to function at their best.  When foods are overly processed, many of these critical components are lost during processing.
  • Whole foods help with weight management.  In this Research Review, the authors discuss the thermic effect of digesting food. For those that aren’t familiar with the concept, the thermic effect is looking at the energy required for digestion, absorption and disposal of food.  The study compared the consumption of two calorie-matched cheese sandwiches.  Now, one could argue that a cheese sandwich in itself is quite processed. But we’re looking at good, better, best here, not good and bad.  One cheese sandwich contained multi-grain bread and real cheddar cheese while the other was made with white bread and a processed cheese product.  Eating the whole food version took 46.8% more energy to digest than its processed counterpart.  More calories used for digestion means fewer calories available for storage!
  • Not not only does whole food require more energy to digest than processed food, but we also tend to eat less of it.  In a 2019 study, 20 volunteers were fed 14 days of ultra-processed food and 14 days of unprocessed food.  The diets were matched for calories, sugar, fat, fibre, sodium and macronutrients.  Subjects were told to eat as much or as little they desired. Then the researchers measured how much food was consumed. Those on the ultra-processed food ate 500 more calories per day than those eating the minimally processed food.  This was reflected in weight gain while on the ultra-processed diet and weight loss on the unprocessed.

2) What works for you

Regardless of whether a food is processed or not, some foods are going to just feel better in your body.  For example, some people have food sensitivities. They don’t tolerate dairy, gluten upsets their stomach or maybe onions don’t sit well with them. Different people have different tolerances for carbohydrates.  For some, they feel like they get good, sustained energy from a diet high in carbohydrates while others feel like they need to ensure those carbs are always balanced with lots of protein and/or fat to avoid a blood sugar roller coaster.  Some thrive on a vegan diet, while others find they really need some animal protein to function at their best.
 When it comes to figuring out what works for you, you need to be your own detective.  How do you feel 30 minutes after you eat?  A couple of hours later?  The next day?  If you have a digestive system that is easily upset or you find your energy level can really fluctuate, it can help to keep a diary. Write down the different foods you eat and any symptoms you experience.  Over time this record can help deduce what in your diet might be causing you trouble and what makes you feel great.

Regardless of what the media might be promoting, at the end of the day, the diet that is best for everybody is a diet customized to suit the needs of each body.

3) What you like to eat

You might think duh, of course, you need to like what you eat, but really, this is a key element that is often overlooked.  Many people decide that when it comes to making improvements to their diet, they have to eat ‘gross, healthy food’.   This thinking comes from a lack of understanding of what constitutes ‘healthy’, a lack of experience with preparing and trialling a variety of foods and the flawed belief that improving our health means never eating some of our favourite foods again.

We often overlook the fact that unless we want temporary results, we are looking at dietary changes that we’re going to be adopting until the end of our days. So we better pick changes that include the foods that we like!  While we want the majority of our foods to contribute to our health goals and taste great, we should also include some of our favourite foods that might not do a darn thing for our health.  This is what helps us stick to our lifestyle long-term without feeling deprived.

If we take into account these 3 factors: 1) less processed food that 2) serves our body and 3) tastes good, we’ll have answered the age-old question of ‘What should I eat?’

As a health coach, this is what I do.  I help clients identify less processed alternatives to some of their favourite foods.  I work with them to figure out what works for their body.  Most importantly, I make sure that we’re designing a way of eating that is enjoyable, sustainable and moves them toward their goals.  Figuring out 'What should I eat? combined with looking at how our relationship with food might be influencing the how, why and how much we eat is the health coaching sweet spot.
