Why Diet and Nutrition should be Paired

Content by Anna Kallianteri, RD, BSc, MSc, Dietitian

In today’s fast-paced world, where convenience often takes precedence over mindful choices, it is becoming increasingly crucial to prioritize our overall health and well-being. While there are numerous factors that contribute to a healthy lifestyle, two key pillars stand out as essential components: fitness and nutrition. Often discussed in isolation, the true power lies in the synergy that arises when these two elements come together.

By understanding and embracing the intrinsic connection between these two pillars, we can unlock a host of benefits that contribute to our overall health and quality of life including reduced risk of chronic diseases and mortality, more effective weight management, improved mental wellbeing and sleep.

The importance of pairing fitness with nutrition

It is well established that both diet and exercise are vital for overall health, but you may not know that there is evidence that integrating both nutrition and physical activity produces greater benefits than focusing on one or the other (1).

Eating healthy and being active have similar effects on our health. These include:

  • Reduce the risk of chronic diseases, such as diabetes, heart disease, high blood pressure, stroke, and some cancers and associated health conditions
  • Prevent weight gain and/or promote weight loss
  • Improve overall wellbeing

Disease Prevention and Longevity

Health food or exercise alone isn’t enough to prevent chronic disease, new research shows. Not surprisingly, people with both higher levels of physical activity and better-quality diets had the lowest mortality risk. A big scale prospective study on UK national data (2 ), showed an overall positive association between physical activity levels with a lower mortality risk, and further that, those who regularly engaged in vigorous exercise — the kind that makes you break a sweat — had a particularly lower risk of cardiovascular disease mortality.

Combining a nutritious diet with regular physical activity has a protective role against the risk of heart disease (3). Combining the two with behavioural counselling is very important especially in individuals at increased risk of cardiovascular disease (4).

Also, the combination of dietary interventions with regular exercise can significantly favour our overall health by modulating our gut microbiota with a protective role against obesity, type 2 diabetes, cardiovascular and non-alcoholic fatty liver disease (5).

Sustainable Weight Management

Physical activity in combination with healthy dietary approaches is key when it comes to preventing overweight/obesity and achieving desired weight management long-term.

In fact, one review showed that combining modest calorie restriction and exercise was the best way to achieve weight loss. In some cases, combining the two led to over five times more weight loss compared to exercise interventions alone (6).

Various factors affect and influence someone’s energy balance. There is a general consensus that weight loss occurs with a negative energy balance (energy expenditure is higher than the energy intake). There is a dynamic, non-linear relationship between energy intake and energy expenditure that is affected by factors such as diet composition, body composition, the type and amount of someone’s physical activity levels, the thermic effect of food, an individual’s hormones, environmental and lifestyle factors such as sedentary behaviours, mood and stress, to name a few (7).

Exercise can affect appetite in two ways. Regular exercise may help manage hunger by regulating your hunger hormones and thus preventing overeating (8). That being said, excessive exercise may increase appetite as well as injury risk, so considering what sort(s) of exercise fits to your lifestyle and that is sustainable to you, is key (9).

Maintaining regular physical activity increases energy expenditure and resting metabolic rate which means your body uses more energy even at rest (10). This allows you to have more flexibility with your diet, so that weight loss feels more enjoyable, less restrictive, and more manageable long-term (11).

Improved Mood

General interventions to promote a healthy lifestyle that incorporates healthy dietary habits and regular exercise has been associated with overall improvement in mental health (stress management, socialising) and overall quality of life and healthy aging (12).

By adopting a balanced diet and engaging in regular physical activity, we can experience a multitude of positive effects on our mental well-being. Not only do these practices help reduce stress levels, but they also have the potential to enhance brain activity. Moreover, the release of endorphins through exercise can act as a natural antidepressant, fostering improved self-esteem and preventing depressive symptoms.

Specifically for women, there is evidence to suggest that when it comes mood, women are more sensitive to dietary triggers, meaning that compared to men, women may have higher needs for exercise to achieve mental wellbeing depending on the type of food groups consumed. Caffeine, fast food and high glycemic foods for example can trigger mental distress whereas this did not apply in men, according to a recent study (13).

Better Sleep

Diet, exercise and sleep are very tightly interconnected and their relationship is bi-directional. A very interesting recent study suggested that the quality and sleep alertness of an individual after waking up is positively influenced by having higher physical activity levels the day before, by consuming a breakfast that is rich in carbohydrates and when a lower glycemic response after consuming breakfast is produced (lower rise in blood sugars after breakfast) (14)

Additionally, diet and exercise can influence your sleep habits. It’s recommended that you don’t exercise heavily or eat right before bedtime. Healthy habits in both areas can turn restless nights into comfortable ones.
