Common Mistakes With Nutrition

With any exercise program, the nutrition component is important, if not more important, but a lot of people may not know a few common mistakes that you are making while trying to change your diet! Breaking a habit in regards to nutrition is hard, it only takes one slip up and you’re back to square one, therefore it is very important to nail these first go and keep your nutrition on track.

Under Eating 

Many individual think that to lose weight, you simply just cut out a few meals and therefore your calorie intake will drop, therefore resulting in weight loss? Sounds fairly easy in concept, but it is not correct and you are only harming your body and depriving your body of crucial nutrients!!

Our bodies typically have around 2 days worth of glycogen (carbohydrate stores=energy), which maintains blood sugar levels. By continuing to ‘starve’ yourself in the pursuit of weight loss, the opposite happens, this will in face slow down your metabolism, leading to a lack of energy. As the process continues your body is pretty much solely relying on protein and ketone bodies which are made from fat as its only source of energy. So in saying that, do not under eat, see a fitness professional, work out what calories you need to be consuming and do not starve yourself to lose weight, you are only damaging your own health!!!

Im sure by now most of you would have heard the saying that carbs are bad, or to avoid carbs because they make you fat… in reality a healthy portion of carbs are important and are important for weight loss. You need to understand that when the term ‘carbohydrates’ is being used, it is a broad term and that not all carbs are the same, its about the quality and quantity of carbs in the diet that is important. 

Carbohydrates are generally the bodies main source of energy in a balanced diet, they are broken down in to glucose (sugar), which is used by our body for energy, fuelling all our activities. 

Lets get into the fun part, should I cut out carbohydrates? 

If we were to cut them out, we could live without the glucose (sugar), it is unrealistic to think we can cut them out completely, but having a balanced diet requires carbs. Without carbs, it will be difficult to obtain enough fibre in our diet, which is important for a healthy digestive system.

By cutting carbs out, it could put you at an increased risk of being deficient in certain nutrients (calcium, iron, b vitamins to name a few), this would also mean you would need to substitute by increasing amount of fats and proteins which is generally higher in saturated fat, and we do not need that level of cholesterol to rise in our body! 

So in short, don’t cut out carbs, they are important in our macronutrients, just adjust what type of carbohydrate you are eating, more starchy foods, such as fruits, vegetables (5 serves a day), wholegrain varieties in comparison to the sweets, cakes and pastries which will affect weight loss.

Thinking That You Need to Eat 5-6 Times Per Day

Im sure you’ve heard of this one as well, you need to have breakfast first thing in the morning and every 2-3 hours have a small/medium meal, it will help your metabolism and help you lose weight. While eating does slightly raise your metabolic rate while digesting and metabolising food, it all comes down to calorie intake throughout a 24 hour period, not the number of meals you have. Some individuals will only have 2-3 meals per day, large in calories, whereas, other individual may have 4-5 meals of medium calorie intake.

Our bodies are well equipped to handle short periods of ‘famine’ (5 & 2, intermittent fasting - topic for another blog altogether), so don’t get caught into the whole ‘breakfast is the most important meal of the day’ topic or needing to eat 5-6 meals per day, every individual is different, remember that, what works for me, may not work for you, we need to individualise our nutritional intake and implement something that works for you and your time schedule also.

 Protein Intake

By now, you should know that protein intake is a key part of weight loss, this can be due to many different factors, including; reducing appetite, increased feelings of fullness, decreased calorie intake and a increase in metabolic rate!

In every meal you have, you should include some form of protein, carbohydrates and fat, so you can space your calories out throughout the day, every individual’s protein intake a day is different, the general rule is about 0.8 grams of protein per kilo of body weight, this can be increased to 1-1.2 grams of protein per kilo of body weight once training intensity and days increase to supplement the muscle growth and repair.
