Controlling your Hunger

When you are trying to lose weight, there is nothing worse than insatiable hunger!  Here are some tips to try and keep your appetite at bay.

  1. Eat regularly and don’t skip meals.
When you leave a long gap between meals, it is easy to overeat at the next meal due to excessive hunger.  Eating small, regular meals will allow you to control your portions.

  1. Are you really hungry?
Do you physically need to eat or is something triggering you to want food?  Physical hunger is when your stomach is rumbling or you may feel light feel light-headed or dizzy.  There are many eating cues that can influence you to eat when your body does not need sustenance.  These can be particular people, places, circumstances as well as thought and emotions.  Emotional or psychological cues such as stress, feeling depressed, bored or anxiety are very common and it's important to devise strategies to deal with them in order to maintain your weight.  Strategies include going for a walk (get away from the kitchen!), having a relaxing hot bath with a good novel or calling a friend to talk things through.  For successful weight loss and weight management, it is important to learn the difference between physical hunger and the psychological inclination to eat and be able to control these urges.

  1. Let yourself feel a little hunger
It is okay to feel hungry sometimes when you are losing weight.  Even after a meal or snack it is okay to not feel completely full.  Try to learn to be more comfortable with this feeling.  The next meal is always not that far away.

  1. Eat your vegetables
Vegetables not only are full of nutrients, but they contain high levels of fibre which help keep hunger at bay.  Adding plenty of vegetables to your meal also increases your meal size without adding additional calories and makes your  stomach feel fuller!  If you are feeling hungry between meals or snacks, ‘free vegetables’, such as carrot, celery, beans, capsicum are low in calories and good to nibble on to get you through.

  1. Keep sipping on water
As the saying goes, “Don’t confuse thirst with hunger”.  Are you really hungry or perhaps just thirsty?  Water helps control your appetite and help fills you up.  Carry a drink bottle with you during the day and have a glass or two of water with every meal.

  1. Eat slowly

Take the time to sit down and enjoy the flavour and savour the taste of your food.  Eat your meal in a similar way a wine taster savours a fine glass of wine.  Take a moment to enjoy the foods visual appearance and aroma.  When taking a bite, be mindful of the foods taste and texture.  Maximise it’s exposure to your taste buds.  Eating slowly and mindfully will give you more satisfaction and control over your eating. 

  1. Get enough sleep!
Two particular hormones which control weight and appetite are called ‘Leptin’ and ‘Grehlin’.  Research* has shown that these hormones can be disturbed with lack of sleep.  Leptin is produced by fat cells and allows us to feel satisfied after a meal.  Ghrelin triggers our hunger.  Studies have found that sleep deprivation decreases leptin and increases levels of grehlin.  This makes us not feel as satisfied after a meal and leads to cravings for carbohydrates and high fat foods.  It is recommended we aim to have at least 7 hours of sleep per night to keep your body healthy and help promote healthy eating.

How Much Dietary Fat Should You Consume During Weight Loss?


Fat contains twice as many calories as carbohydrate and protein, so it makes sense to reduce the amount of fat in your diet if you want to lose weight. 

However you shouldn't eliminate all fat from your diet. Your body needs some fat for vitamin absorption, hormone regulation, the health of your heart and the protection of your vital organs. And you need some fat in your diet to enjoy the flavour and texture of your food.

How Much Dietary Fat Should I Consume During Weight Loss?

Females:
Fairly healthy with normal cholesterol and triglycerides: 40g fat per day
At risk of heart disease, high blood pressure or diabetes: 30g fat per day

Males:
Fairly healthy with normal cholesterol and triglycerides: 50g fat per day
At risk of heart disease, high blood pressure or diabetes: 40g fat per day

How Much Dietary Fat Should I Consume to Maintain a Healthy Weight?

Fats should not contribute to more than 30% of your daily calorie intake, but many Australians consume more than 40% of their daily calorie intake from fat.
Assuming that you will remain fairly active when you reach your weight loss goal, you should consume the following levels of dietary fat:

Females: Fairly healthy with normal cholesterol and triglycerides: 65g fat per day
At risk of heart disease, high blood pressure or diabetes: 55g fat per day

Males: Fairly healthy with normal cholesterol and triglycerides: 85g fat per day
At risk of heart disease, high blood pressure or diabetes: 70g fat per day

To find out how much fat is in your favourite foods, visit the
Calorie King website.
In summary, it's important to moderate your intake of dietary fat but don't eliminate it completely. Choose foods that are high in healthy fats such as monounsaturated, polyunsaturated and omega-3 fats. And limit your intake of foods that contain unhealthy fats (saturated and trans fats) as they increase your blood cholesterol levels.
