Mandy,
There isn't any guaranteed quick way to loose weight, although, the one method which provides the best results is calorie counting. If you count your calories daily and stay within your allotment of calorie intake, then you will loose weight.
What is the right amount of calories for you? The number of calories differs for every person.
The standard diet calls for 2000 calories per day. This is good for maintaining weight for a semi-active individual. This can be difficult with today's current american cuisine.
For loosing weight, I, personally, decrease my calories down to 1800 per day. After a week or two, it is suggested to decrease farther to 1500 calories per day. This diet works well for my husband.
I hope this answers your question, Mandy.
Warmly,
Sass
