Beyond Calories: A Deep Dive into the Science of Diet and Nutrition


Eating is far more than simply consuming calories. In fact, the science of diet and nutrition is a complex field that’s just beginning to be understood by the public. But as our understanding grows, so do the ways in which we can customize our diets based on our unique genetic makeup, lifestyle choices, and health goals. In this article we’ll explore some core concepts of dieting: macronutrients, micronutrients (or phytonutrients), and calorie density. Dr. Mahmud Kara will delve into how food impacts your body beyond simple calorie counting and takeaways for how to optimize your diet based on these principles!

What is the science behind eating?

The science behind eating is a complex and nuanced topic. It’s easy to get lost in all of the details, but there are some key concepts that can guide your understanding of diet and nutrition. This section will help you understand how food impacts our bodies more than just calories, how we know if a diet is working for us, and whether or not there is an ideal ratio of macronutrient to micronutrient intake that works for everyone.

What are macronutrients, micronutrients, and phytonutrients?

Macronutrients are the nutrients that provide energy. They include carbohydrates, proteins, and fats.

Micronutrients are vitamins and minerals that your body needs in smaller amounts to function properly (i.e., for things like digestion).

Phytonutrients are plant-based nutrients that have been shown to have benefits for human health but haven’t yet been fully researched for their effects on humans.

How does food impact our bodies more than just calories?

Food is more than just a source of calories. It also contains macronutrients (fat, protein and carbohydrate) and micronutrients (vitamins and minerals). These nutrients work together to help your body function properly.

Food impacts our bodies in more ways than just providing the energy it needs to burn through the day: at a cellular level, food can change how we age or even whether we develop certain diseases like cancer or heart disease later in life.

How do we know if a diet is working for us?

  • Monitor your weight
  • Monitor your body fat percentage
  • Monitor your body measurements (waist circumference, hip circumference and abdominal circumference)
  • Monitor your energy levels
  • Keep a food diary: write down everything that you eat or drink throughout the day. This will help you see which foods are contributing to any changes in weight or energy levels.

Is there an ideal ratio of macronutrient to micronutrient intake that works for everyone?

If you’ve ever tried to lose weight, you may have heard that there are certain ratios of macronutrients (protein, fat and carbohydrates) to micronutrients (vitamins and minerals) that work for everyone. While it’s true that these ratios can help guide your food choices, there is no one-size-fits-all diet out there that works for everyone.

The truth is that not all foods are created equal–some foods are better than others when it comes to nutrition and health benefits; some are more nutritious than others; some are more healthy than others; some are more energy dense than others (meaning they contain more calories per bite); while others provide greater satiety (the feeling of fullness). So while a low fat diet may work well for one person trying to lose weight because they find themselves hungry all the time without enough calories coming in each day–if another person tries this same approach without factoring in their unique needs based on their age/gender/activity level then they might end up feeling even hungrier while still being underweight!

Can we develop a personalized diet based on our unique genetic makeup?

The short answer is a resounding yes. You can develop a personalized diet based on your unique genetic makeup. But that’s not all–the future of nutrition is also likely to include personalized dietary supplements and nutritional advice tailored to your DNA.

To determine your genetic makeup, you’ll need to have your genome sequenced by one of the many companies now offering this service (for example, 23andMe). This process involves sending saliva samples through the mail or visiting a lab where they swab your cheek with a Q-tip. The company then analyzes the sample and returns detailed information about any mutations in genes related to diet and nutrition that may affect how well you absorb certain nutrients from food or respond differently than other people do when eating certain foods (for example, gluten sensitivity).

Once you know which genes are responsible for these traits in yourself or family members who share similar traits as yours, then it becomes possible for doctors and nutritionists alike who specialize in personalized diets based on genetics research into how different types react differently under various circumstances such as stress levels affecting appetite control hormones like ghrelin which tells us when we’re hungry or full

If a food has a lot of nutrients, will it automatically be good for us to eat it?

This is a great question, and one that we hear often. The answer is no: just because a food has a lot of nutrients doesn’t automatically make it good for us to eat. For example, let’s say you have been eating an apple every day for lunch because they’re healthy and have lots of vitamins and minerals in them (which they do). But what if that apple was actually made with caramel? And what if there was so much caramel on top that it was almost entirely covered by it? Eating this would give you some calories from sugar but not much else beyond that!

This is where calorie count comes into play–it allows us to see exactly how many calories are in each food item so we can compare apples with apples (or apples with bananas).

The quality and quantity of your food matters!

The quality and quantity of your food matters! The more nutrients you eat, the better. Conversely, the fewer nutrients there are in a food item, the worse it is for you. This is true whether we’re talking about carbohydrates or fats–there are no exceptions to this rule.

Similarly, foods that contain more calories will make you gain weight if consumed in excess compared with those containing fewer calories per serving size (e.g., 200 grams). This also applies regardless of whether those extra calories come from fat or carbohydrates as long as they end up adding up over time by contributing toward your daily total intake without burning off during physical activity or exercise sessions throughout each day’s waking hours.”


The quality and quantity of your food matters! You don’t have to be a scientist or nutritionist to understand the importance of eating well, but it helps if you want to learn more about how your body works. There are many different diets out there that claim they will make you healthier, but at the end of the day it comes down to what works best for each individual person. Eating well means finding foods that provide enough nutrients without being too much or too little of anything else–and this may not be as easy as it sounds when so many factors come into play (such as genetics). However, with some research and experimentation we can all find an eating plan that suits our unique needs!
