are low calorie foods good for you?

9th August 2017 by Jess

Calories is such a poorly misunderstood area of nutrition, we decided to bust some myths around them. Once you understand them, your decision making process around food and health will change forever.

Most people will tell you that you have to lose weight to be healthy, when these days, you actually have to be healthy to lose weight. We are seeing more and move evidence that not all calories are equal.

metabolising different calories

Our bodies react very differently to calories from different sources. They may go through similar digestive processes, but the biochemical reactions they trigger can be completely different. To put this into context, let's compare how 1000 calories from fruit juice are metabolised in the body versus 1000 calories from broccoli.

Same number of calories, but two very different sources.

calories from fruit juice

When you consume fruit juice your body quickly absorbs the fibre-less sugars, the glucose (sugar) spikes your blood sugar, which stimulates insulin and subsequently signals to your body to store body fat.

Inflammation goes up, triglycerides are raised (essentially fat in your blood), and leptin, one of the hormones involved in appetite regulation, is blocked. Leptin’s role is to signal to your brain that you're satisfied, and if the brain doesn't receive this message, you are likely to continue eating.

This experience of never feeling like you are full, is a typical feeling of those who follow a low fat, high carbohydrate diet, and constant battle of willpower over wanting to feed that constant hunger, is a tough one, which almost always ends up in de-railing from the ‘diet’, ‘hangry’ moments’ and eating anything and everything in site.

I have personally witnessed this hundreds of time with my clients in my nutrition practice. When my clients stop counting calories and focus on nourishing their body by eating real food, irrespective of the number of calories the food brings to the body, they have a rapid improvement in their overall wellbeing, but they also feel satisfied, and never hungry - which is how life should be enjoyed. They don’t get it, but their bodies understand.

So to answer the initial question of ‘can low calorie foods be good for you?’

…the answer is yes, they can be.

But just because a food is low in calories, it doesn’t mean that it’s necessarily good for you. 100 calories of sugar and refined foods is 100 calories that your body would much rather receive from more nutrient abundant sources like nuts, seeds, fresh fruits and vegetables, sustainably sources meats and fish, eggs etc. This is a far better gauge for working out your food choices.
