Calorie Restriction and Nutrigenomics

Calorie Restriction and Nutrigenomics

What is calorie restriction

Calorie restriction is a dietary intervention that is low in calories, but maintains proper nutrition and is known to decrease your biological rate of aging, thereby increasing your lifespan.

But any calorie restriction effort without knowing the exact amount of calories required to optimise and sustain your “basal metabolic rate” (BMR), your ability to digest food and your ability to perform physical activities will only tip the scales against your effort.

Here, the introduction of an optimal “calorie balance” into your lifestyle can become very important.

What is calorie balance

Calorie balance simply means a perfect match between the amount of calories you consume through food and the amount of calories you spend through your physical activities and your various energy needs such as breathing, digesting, walking and sleeping.

Are you in perfect calorie balance? If so, is it optimal to your health requirements? We may be able to answer these questions for you, as follows.

Calorie balance may impact your health

Let’s look at a larger case study of how calorie restriction effort pans out in a certain demography of diverse individuals, with you in question as a possible ‘case study example’ here.

Your own human mechanism balances the day-to-day differences in your energy consumption, so decreasing the size of your meal may not make you all thin and shiny.

In short, a reduction in your calorie intake may well be counteracted by your own mechanism, which might slow down your metabolic rate and possibly increase your calorie intake, making sure that your calorie balance is tilted more towards your weight gain than towards your attempted weight loss.

In short, it’s all about how your hormonal mechanisms react to your various practises of calorie intake and the mismatch in the energy expenditure.

Calorie restriction does not help obesity

The reason why men on calorie restriction for years on end remain largely obese can very well be deduced from this perspective. The same can be explained by reversing the roles of individuals with lean men in this particular demography as to why they never seem to gain weight, despite their best calorie restriction efforts.

Obesity, for example, is complex and multifactorial in nature that a mere calorie restriction diet without understanding your genotype and what your own genetic markers point to is not an ideal way to make your informed health decisions.

Calorie restriction may also result in the decreased levels of your metabolism, can cause nutrient deficiencies and fatigue, can lower your immunity and even result in reduced fertility.

Why are DNA-based dietary recommendations good for you

Calorie restriction is, therefore, a tricky proposition.

The difference between you and me is genetic. Your genetic predisposition may point to something different from mine; your genetic markers may point to something different from what my genetic markers point to. A calorie restriction effort without understanding what our genetic markers point to cannot be part of our informed health decisions.

No single, universal dietary recommendation works for everyone. Therefore, the solution lies more in dietary recommendations based on DNA-based nutritional interventions than conventional science would permit us to choose.

Truth be told, calorie restriction diet can lead to long term weight gain.

In this new age of modern, scientific advancements, it is incumbent on us individuals to choose from the maze and clutter of million cures what is most favourable to us in terms of what our genetic predisposition mandates and what our biological markers require of us.
