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.

Non-Hungry Eating: How to Take Control

If you eat when you aren't hungry you may be finding it difficult to lose weight. Here are some tips to help you fight the urge to eat when you aren't hungry, a habit which we call 'non-hungry eating':

What are Your Eating Cues?

When you understand why you eat when you aren't hungry you can take positive steps to prevent it from happening again. Do you eat when you are feeling down or lonely? When you are engaging in certain habits or activities? Because the weather is gloomy? Or simply because food is put in front of you?

Next time you catch yourself heading to the pantry when you aren't hungry, think about your motivations for wanting to eat. Then you can work toward re-gaining control of how you respond to your cues. Try removing the cue (e.g. take the packet of chips away from the TV room if you eat when you watch TV). Or you can actively respond to the cue in a different way (e.g. call a friend instead of heading to the kitchen when you are bored). 

Don't be disheartened if you don't succeed in changing your habits straight away. Change is a process that takes time, dedication and the courage to persevere - even when you don't succeed.

Measure Your Hunger

Be aware of when you are engaging in hungry eating because hunger is an appropriate cue to eat. To ascertain your level of hunger, try using the following scale to rate your hunger before eating, then five minutes after you have started eating and then again when you have finished your meal:

Rating / Physical Sensation

1 Starvation, physical pain

2 Definite physical symptoms: headache, low energy, light headed feeling, empty stomach

3 Beginning of physical signs of hunger

4 Could eat if suggestion was made

5 Neutral

6 Satisfied

7 Feel food in stomach

8 Stomach protrudes, beginning of mood alteration

9 Bloated, definite mood alteration

10 Definitely full: physical pain and numbness

People who are successful at weight loss generally wait until they are at a rating of 2 or 3 before they eat, and then they only eat to a rating of 6.

Remember that you are in control of how you respond to your eating cues. And when you control how you respond to your eating cues, you can start to control your weight.

Find Your Motivation to Exercise: 10 Tips

Struggling to get out the door for your afternoon walk? Or finding that extra hour of sleep more appealing than hitting the pavement for your morning stroll?

Despite being well aware of the benefits of exercise - and knowing how great you will feel after exercising - you may find yourself struggling with motivation. Read on for some tips:

1. Adopt an Exercise Buddy

Exercise buddies keep you accountable - there's nothing like the commitment of knowing that someone is waiting for you. Walking groups or cycling bunch rides are a great way to meet people, and as your fitness improves, other people who have greater fitness will spur you on!

2. Walk to a Beat

Listening to music can motivate you during exercise, resulting in longer, more enjoyable sessions. If music isn't your thing, try listening to books on CD or podcasts.

3. Try Something New

Try cycling, aqua aerobics, water running, walking, swimming or even dancing. There is a form of exercise that you will love out there - you just may not have found it yet!

4. Just Do It

Sometimes overanalysing can be detrimental - you just need to get out there and exercise!

5. Enter Fun Runs and Walks

You don't have to be a serious runner or athlete to enter races, most have 'walker' divisions. Aim to do a fun run or walk to sustain interest and give yourself a goal to work towards.

6. Schedule It

Book an appointment with yourself and prioritise exercise just like you would any other appointment.

7. Exercise Early

If you want to get something done, do it before other tasks and responsibilities accumulate. If you exercise early you will benefit from an elevated metabolic rate for the remainder of the day, which means you are likely to burn more calories. If you can't fit exercise in early, try to do it before you get home. Once you get home, it can be difficult to go back outside!

8. Be Prepared

Keep a bag of exercise clothes at your work or in your car - you never know when you may be able to fit in an exercise session. If you are going to exercise in the morning, organise the gear you need the night before.

9. Keep Track

Keep an exercise diary, or use a heart rate monitor to measure your exercise intensity, duration and calories burned. When you meet your exercise goals, treat yourself to a non food-related reward. When you are pressed for time, a pedometer is a great way of measuring your incidental exercise.

10. Be Flexible

Don't worry too much about missed exercise days, but try to identify the barriers that prevent you from exercising and address them.

How Much Exercise Do I Need to Do to Lose Weight?

The amount of exercise you need to do depends on your weight loss goal. If your goal is:

1. Weight loss 150-250 minutes of moderate intensity* physical activity per week provides modest weight loss. People with a body mass index that classifies them as overweight or obese should aim for more than 250 minutes of exercise per week (e.g. 5 sessions of one hour per week) and perform resistance training to increase the amount of metabolically active muscle tissue in their bodies and reduce their health risks.

2. Weight maintenance More than 250 minutes per week of moderate intensity physical activity per week (e.g. 5 sessions of 50 minutes per week).

3. Preventing weight gain 150-250 minutes of moderate intensity physical activity per week (e.g. 5 sessions of 30 - 50 minutes per week).

*Moderate intensity physical activity is an increase in your breathing rate to a point where you are still able to talk comfortably but not sing. A more technical explanation is that it is exercising in a range of 65-75% of your maximum heart rate. Modes of exercise which are best suited to moderate intensity exercise are brisk walking, swimming, bike riding or cardio machines at the gym. Exercise should be continuous rather than in short bursts (these short bursts occur in sports such as tennis or touch football).

Remember that it's very difficult to lose weight through exercise alone. If you try to lose weight without reducing your calorie intake you'll need to exercise for at least 300 minutes a week! The best way to lose weight is to exercise AND consume fewer calories. Not only will you lose weight at a faster rate, but by engaging in regular aerobic exercise you'll keep the weight off for life.

How to Increase Your Metabolic Rate

To increase your metabolic rate, or the rate at which your body burns energy, you need to exercise at a moderate intensity (a level where your breathing rate is elevated, but you can still carry out a conversation) for at least 250 minutes a week. You also need to eat small meals every three hours. 

Metabolism Explained

Your metabolism is important in determining how much body fat you burn. Every person's metabolic rate is different, but in theory, raising your metabolic rate by 10% can decrease your body weight by up to 7.5 kilograms! Your metabolic rate comprises of three factors, two of which you have the power to change:

1. Resting metabolic rate the amount of energy expended when you are sleeping or sedentary (60 - 70% of the average person's daily energy use)
2. Physical activity (20 - 25% of the average person's daily energy use)
3. Thermogenesis an increase in your resting metabolic rate in response to stimuli such as food digestion (10% of the average person's daily energy use)

The two factors that you have the power to change are the physical activity (engage in regular exercise) and thermogenesis (eat every 2-3 hours).

Don't Slow Your Metabolism

One of the fastest ways to slow your metabolsim is to 'crash diet', or try fast diets and fasting. When you lose weight quickly, your body responds to perceived starvation by slowing your metabolic rate to conserve energy. Hence when you start eating normally again, your body stores fat because its metabolism has slowed!

Yo-yo dieting has a similar effect. The more weight you lose, regain and lose again; the more muscle tissue you will shed. Unlike fat, muscle tissue is metabolically active.

So by maintaining a healthy metabolism with exercise and regular eating, you'll enjoy a healthy metabolism - and a healthy weight.

Meal Timing for Weight Loss

If you are trying to lose weight (or maintain a healthy weight) you need to eat approximately every 3 hours and consume five small meals a day. If you consume less than five small meals a day your metabolism will slow making it difficult for you to lose weight. Recommend eating at the following times:

• Breakfast: 6.00am - 8.00am
• Morning Tea: 10.00am - 11.00am
• Lunch: 12.00pm - 2.00pm
• Afternoon Tea: 3.00pm - 5.00pm
• Dinner: 6.00pm - 8.00pm (try and finish your last meal before 8.00pm).

If you leave more than three hours between your meals you may feel hungry - and it's very difficult to maintain your resolve to lose weight when you feel hungry all the time! Plus when you know when your next meal is, you are less likely to turn to convenience foods. 

Healthy Meals

A healthy meal or snack is small in portion size but fills you up for at least 2-3 hours. So next time you are tempted to grab fast food on the run or reach for the biscuit jar at work, ask yourself, "Is there a better choice I could make to help me get through the day?". Then try the following:

- If your meal or snack won't fill you up for at least two hours, consider more healthy options. Low fat, low GI snacks with protein will help you feel full for longer: try low fat yoghurt, fruit, light cheese and wholegrain crackers.

- If it's less than three hours before your last meal, think about your real motivation for eating. Ask yourself questions such as, "Am I really hungry?" and "How will I feel afterwards?". You may find that you are engaging in non hungry eating.

- If you have a tendency to eat out of habit, i.e. you tend to snack at certain places or times of the day, think of ways to break these habits. For example, don't keep a stash of chocolate in your top drawer at work.

- Don't attach emotions to food. If you eat when you are stressed or bored; think about alternate, non food-related ways to improve your mood such as going for a brief walk.

- Before you eat, sit down and place your food on a plate: that way you are more likely to acknowledge the calories.

Eating the right foods at the right time can make a huge impact on your weight loss efforts. 

SLEEP More, WEIGH Less

Did you know that under-sleeping can lead to poor performance and impaired judgement and has also been linked to depression, obesity, diabetes and hypertension. A new study of 1,200 people showed that the average Australian adult gets less than seven hours sleep a night, below the seven to eight hours recommended by sleep experts.

A study by Columbia University, found people who slept four hours or less per night were 73% more likely to be overweight or obese. Also, people who habitually slept for five hours had 15% more ghrelin, a hormone which increases feelings of hunger, than those who slept for eight hours. Those who slept for less time were also found to have 15% less leptin, a hormone which suppresses appetite. "These differences are likely to increase appetite, and therefore contribute to obesity" Dr Taheri states. The subjects in the study also tended to eat more sweet and starchy foods when sleep was cut short.

While research continues, sleep still remains one of the body's most mysterious processes. We do know that sleep is absolutely necessary for survival and even occasional sleeping problems can make daily life feel more stressful or cause you to be less productive. Sleep loss also affects growth hormone secretion that is linked to obesity and impairs the body's ability to use insulin, which can lead to the onset of diabetes. It is paramount that we discover more about this activity where we spend a third of our lives - sleeping.

There are prescriptions and non-prescription drugs, herbs, remedies, technologies, etc that may help you get a good night's sleep. Some work for some and not for others.

Here are some tips you can try at home tonight. These tips are intended for the average adult, but not necessarily for children or persons experiencing medical problems:

• Imagining - Think of a hammock - you're up off the ground, wrapped in a cocoon of comfort, swaying gently in the open air. The sun is warm on your face and there's a cool breeze blowing you back and forth. This visualisation helps you "see" what the reward for sleeping will be, getting you more in the mood to sleep. Visualisation has proved helpful in developing the appropriate brain wave patterns for sleep.
• Magnesium - Has a calming effect on the nervous system. It is part of bones and cells, especially the smooth cells of arteries, and assists in the absorption of calcium and potassium. Over 300 enzymes in our body need magnesium to function properly. It is so important, that the brain stores a "safety supply" to have in the event of a drop in the magnesium reserves.
• Nutmeg - Grind fresh nutmeg and serve it with warm low fat milk and a touch of honey. Milk is naturally high in calcium and rich in tryptophan; together they can be a powerful tranquilizer (and very delicious).
• Hot foot baths - In the Eastern World, a hot foot bath is a traditional remedy; it draws blood from the brain to calm a racing mind. Try soaking your feet in a hot bath with a cupful of Epsom salts and a few drops of lavender essential oil, which will soothe you. Your feet absorb the magnesium from the Epsom salts and relax you further.
• Stomach rub - Soothes down the digestive system and helps bring about deeper relaxation. Lie on your back and place your hand on your belly button. Begin to make small circles in a clockwise direction as you gently glide your hand over your stomach. Let your circles gradually become bigger and bigger. When your circles reach the outside of your stomach, gradually reduce their size until you are back at your belly button again. Reverse the direction; repeat the whole series with your other hand and do this several times. Doing this with lavender oil can create an even more relaxing experience.
• Listening to an audio book - The brain works like a tape player - with one main auditory loop that processes words. If you fill that loop with an interesting book, there's no room for your own worrisome internal narrative. Especially helpful for those who have continuous thoughts running through their heads.
• Deep breathing - Take a deep breath in then slowly release out - focussing on your breathing causes your mind to get distracted from your worries and focussed on your breathing. Doing this for a few minutes can relax your mind and help you get a more peaceful sleep.
• Turn it off - Sleep experts suggest refraining from doing work, watching television, or being on the computer at least an hour before bed time. This allows your brain to start to 'wind down'.
