A few simple lifestyle changes have helped me lose 26.5kg AND slash my food bill by $35 a week! Over the past six months I have developed my own healthy eating and exercise regime. I began by pushing my one-year-old for an hour a day to the park and around the shops at a brisk pace, using our $20 eBay running pram. I also invested in some second hand hand weights and after extensive research on the Internet, I started my own regime of weight training exercises.

Food-wise, I began buying in bulk and made my own nutritious meals, rather than relying on 'ready to eat' microwave health meals. This way I knew exactly what was in each meal and there was never any waste. I started making my own meal plans and eating smaller portions, going from a 3000 calorie-a-day diet to 1500-1600 calories per day.

Under my new regime I soon began to lose the weight, but the real bonus for me has been in the savings I have made. Changing the way I ate and my portion size has resulted in me saving $35 a week over the past 26 weeks! A win-win situation all round. No personal trainers, fancy diet shakes, pills or supplements - I simply used what I had. I feel fantastic and have the energy levels of a teenager! If I can do it, anyone can!

Three weeks ago we ended up without a cent to spend on groceries and the money situation for the following week was only slightly better. We had to eat, of course, so I raided the pantry and freezer and managed to get by on what we had. We were also running out of laundry powder and toilet paper so I rationed out these things to make sure we made it through until we could afford to stock up. It meant using less laundry powder per wash and a few less squares of toilet paper each visit, but we got through the week without having to buy anything, saving around $300.

The following week we had only $30 for food shopping. I still had things I could use up in the pantry and fridge/freezer, and the rationing of the laundry powder and toilet paper meant we wouldn't need to buy more until the next week. So I spent our $30 surplus for that week on milk, fruit and vegetables.

Last week we were back to normal but my two weeks of poverty made me realise just how much money I can save each week by using less of everything and trying to use up what I already have in the fridge and pantry. Over two weeks I had managed to NOT spend about $570 and I had also cleared out a stack of canned beans, canned tuna and sardines, frozen vegetables, frozen meat and frozen loaves of bread that were taking up space in my pantry and freezer.

I can hardly believe it but we have an extra $2000 sitting in our savings account! I have been a stay at home mum for 18 months. My husband earns a slightly above average salary, which allows me to stay at home with our son. We have a modest home, with modest furnishings and modest tastes. We haven't really had a financial plan since we got married two and a half years ago and have just been cruising along, saving a bit some months and spending it other months.

When I first left work I had full intentions of making a budget, planning our meals, organising our lives and generally being on the ball with our finances. Each month when pay day rolled around, I would say 'this is the month where I get organised!' But it never happened. I am the first to admit that I have been lazy, unmotivated, complacent and ostrich-like. I have been a member of Simple Savings for over a year and always thought we were doing OK and didn't really need to know all these ways to save money. I had heard of the $21 Challenge but wasn't really motivated to try it and we were ticking along as usual - until last month.

With baby number two arriving in three months we needed extra storage space so we extended our garage to make room for all our stuff. This extension made a dent in the savings account which although we knew it would, was quite depressing to see the balance dropping and dropping and not going back up. Lo and behold, motivation began creeping in!

I downloaded all our bank transactions for the month and was horrified to find that I had spent an average of nearly $260 per week on groceries for two adults and one toddler. There were lots of other things I was also horrified to see but I started with the groceries as it seemed easiest. Motivation knocked harder. I decided to take charge!

I read the first two chapters of the $21 Challenge on the website, put a copy of the book on my library request list and did a stocktake of my pantry, fridge and freezer. Imagine my shock when I discovered I had enough ingredients to plan meals for the next 19 days! That's not counting meals like scrambled eggs, pumpkin soup and the emergency baked beans on toast. We had enough food in the house to live on for over three weeks! We just needed fresh fruit and veges and that was about it. I didn't quite make $21 but my first grocery shop after doing the stocktake came to $61, down from $258 per week the previous month.

From then on I watched the bank account like a hawk and knew where every cent went. In previous months when the bank account got low, I would simply pull out the credit card and pay it off on pay day but not this month! This month it stayed in my wallet.

It's pay day again tomorrow and guess what? I have spent an average of $160 per week on groceries, saving us nearly $100 per week. By being aware and thinking to myself 'do I really need that?' and deciding 'no', the savings account has increased by a whopping $2250! That figure makes me weak at the knees! I can’t honestly say where the money has been going before now. We don’t have the latest gadgets, appliances or clothing. I am truly at a loss BUT I have to say I'm pretty proud of myself right now! At the same time, I feel a bit sick that I didn't do this 18 months ago, or even 12 or 6 months ago, but I've done it now. I am motivated to change my ways. I have goals. I have the energy to do this and I have Simple Savings to thank for giving me the tools to continue saving. THANK YOU!

I am 22 years old and on a low income, but am well on the way to saving for my first house! I developed a simple system that keeps my savings goal at the forefront of my mind and encourages the support of those around me.

I've always found it hard to save, but one day I got a big piece of cardboard and wrote 'My House Deposit' at the top. On the right hand side I cut out images of a house, a kitchen and a loungeroom that I would love to own one day. On the left hand side I drew a giant thermometer and on the side wrote the figures $0 to $40 000 ascending, just like on a real thermometer. Whether or not I need $40 000 is irrelevant; I look at this table every day and whenever I save another $500, I colour in with a red crayon up to the amount on the tally. I use hints from Simple Savings, such as making my own lunch every day and not buying clothes if I don't need them and now whenever I make a purchase I think of my house deposit and how much I want it far more than a coffee or new shoes!

An unexpected bonus of having this chart is that I've found my family and boyfriend have become aware of my goals and I get lots of support along the way. This visualisation technique really does wonders, and most importantly you are making a concrete agreement with yourself and you stop losing sight of your goals. I'm already a quarter of the way to reaching mine!

I can make four litres of handwashing gel soap for under $1.00! To make your own liquid gel soap, grate a bar of Sunlight or generic laundry soap into a two litre ice cream container. Pour boiling water to half fill the container and mix to dissolve the soap. Carefully fill to the top with boiling water and mix well. Pour half the mixture into another two litre container and top up both with boiling water again. The gel is very thick once it sets, but a good consistency for its purpose. Store in the two litre containers and refill pump bottles as needed. One pump is all it needs to clean your hands and can even wash dirty dishes if you squirt into the sink!

I add a supermarket gift card to my weekly grocery list and use them all up to shop for Christmas! After doing some calculations I realised that the ready-made Christmas hampers that you pay for weekly cost three times their actual value, not to mention the fact that they can include many products you won't ever use. My new system for buying Christmas groceries lets me buy my own hamper full of items at the current price or on special.

For many people juggling work, family and study, time is the most important saving they can make. I work four days a week, have a three-year-old and studied part-time for a diploma for a year. I got by with these time-saving tips:

1. Lowering my expectations for the house. I don't need a spotless house, but a tidy and lived-in home.

2. Doing my housework little and often, rather than spending huge amounts of time tidying up. I do things like:

- put my little one's daycare bag together for the next day as soon as we get home in the afternoon.
- cook my lunches (pasta and sauce, muffins and so on) once a week and freeze them.
- put my lunch box together from the freezer in the evening.
- clean the toilet by putting a teaspoon of Napisan in it each night. It soaks overnight and the bowl is clean with the next flush.
- do laundry when enough for a load accumulates so we don't have a sudden clothes drought, then an avalanche of laundry to do and put away.

3. Exercising on a stationary bike in front of the TV in the evenings after my little one is in bed.

4. Programming our DVD recorder once a week (Sundays when we get the new TV guide) so I don't miss my favourite shows.

5. Filling cereal bowls with water if I am rushing and have to leave the breakfast things. This makes them easier to clean later and stops ants.

6. Trying not to double handle things. Rubbish goes straight in the bin, meat is put in meal size portions in plastic bags and frozen as soon as it gets home, magazine subscriptions go straight to magazine rack when they arrive in mail.

7. Leaving rooms better than when I arrived, so the need to tidy doesn't build up. It only takes five minutes to put laundry from the floor to the hamper, make the bed, wipe a bench, replenish the toilet paper.

8. Recruiting my little one to help - she's only three but she can put dirty dishes in the sink, put toys away in her room, dirty clothes in the hamper.

9. Shopping for groceries by myself in the evening so hubby can watch his TV shows in peace and I am not tempted to go to other stores as only the supermarket is open. Also many things are marked down at that time.

10. Trying to do three things for myself that make me feel happy each day, like listen to podcasts while I do the housework.

11. Writing the shopping list progressively through the week so I can pick it up and go when it's time to do groceries.

12. Storing the bedding in storage containers under each bed so it's quick to make the bed, especially when changing my little one's wet sheets in the middle of the night.

13. Shopping for presents at sales during the year (online or in stores) so I don't need to go to crowded stores during the Christmas rush.

14. Not beating myself up if I find lifestyle changes tricky at first - I am afterall human!

My husband and I have began saving up to $30 per week on our grocery bill since we invented 'Grandma's Day!' When we go to the supermarket we ask ourselves, 'would Grandma have been able to buy this item in her day 60+ years ago?' If the answer is no, then we decide we don't need to buy it either! This saves us money on a whole range of items such as fancy dips, designer coffees and biscuits. We used to pay over $3 for a pack of 10 biscuits, now I can make 12 biscuits for around $1. Using plain yoghurt as a base we are even making our own dips; there are so many websites with great dip ideas. Now we are saving valuable money and our waistlines too!

At 12 years old, my daughter is already helping our family save money on snacks using her Simple Savings skills! With five children in the house, we do a big shop just once a month and are careful to make our food and treats last until the next shop. Recently we were nearing the end of the month and getting low on food. I arrived home one day to find my daughter baking biscuits. 'They're Doos!' she told me. 'You always said if there was nothing in the cupboard, we had to make do, so I made Doos!'

The name has stuck in our house and now whenever we have 'nothing' in the house for lunch boxes, snacks or afternoon tea, she just makes a batch of 'Doos' using whatever she can find in the pantry to 'make do' with. She is proving to be very inventive with her recipes and is turning out to be a real baker. She'll turn out simple but delicious treats such as honey joys, choc chip biscuits, Anzac biscuits, pikelets and pancakes in no time at all! She really has shown that you can make something from almost anything in the pantry and would be wonderful at the $21 Challenge! Here is the recipe for her latest creation, called 'Sort of Scones!'

1 cup oats
1 cup self raising flour
1/2 cup sugar
125g butter
1 egg
1/4 cup milk

Mix all ingredients together, then roll into balls and place on a greased baking tray. Bake in a moderate oven (around 180C) for 10 minutes.

I couldn't be prouder of my daughter's efforts to help us save money and keep everyone well fed. Whenever we think our parenting has a lot to be desired, it's moments like this which prove we have to be doing something right - good things do rub off too!

I am putting an end to my bad habits for good! I decided to give up one bad habit a month this year - something that costs me money and is not good for me. At the end of each month, I can reward myself have that thing again but I find after not having it for a month I no longer crave them any more!

For January I gave up chocolate. It was hard at first and each time I wanted a chocolate I had to deny my cravings. I also made sure that I did something positive, such as going for a walk until the craving passed. I also made sure that I didn't buy something more expensive to replace what I was giving up. The idea is to save money and look after my health.

When February came I allowed myself chocolate again but found I didn't want it any more! For this month I have given up fruit juice. I am finding that I actually enjoy drinking water and if I need more flavour I just squeeze some fresh juice into it.

In March I plan to stop catching the bus. Instead I am going to walk the 40 minute trip to and from work each day. Although it will take an extra 20 minutes of my time each trip, I will get 40 minutes of exercise for a cost of 20 minutes. Again I hope to continue this indefinitely.

In April I will give up alcohol. When I am out I will order a soft drink or lemon, lime and bitters, which will save me money and be good for me.

Each month I plan to give up something that is small but costly and not so good for my health. By the end of the year I should end up with a lot more money in my pocket and be far healthier too!
