The honest answer is that there is no quick fix.
If you want to lose weight, and you want to maintain that weight loss, then you have to change the way you eat for good. it?s no good if you take a quick fix diet to lose vast amounts of weight, because as soon as you start to eat the way you?ve been used to, you?ll start to pile the weight back on again.
I personally would recommend that you count the amount of calories you eat. You can do it either via a calory counter, or you could use a programme such as weightwatchers which does work on a similar principle, except it?s done in points not calories.
The average woman needs approx 1900 calories to maintain her body weight, if you lower that to 1100 calories per day, you can expect to lose approx 2 lb per week. This is a safe weight loss, and no more than 2 lb a week is recommended unless you have a very significant amount of weight to lose.
Record everything you eat, including snacks. Where possible, weigh the food you?re eating to ensure that you?re not miscalculating the calories. Try to drink two ltr of water per day, this will ensure that you flush out all the waste products and that will include the fat that you?ll be burning.
Limit the amount of red meat you eat and try where possible to stick to fish and chicken. Also eat less carbs and more protein, but don?t cut out carbs altogether, try to limit your carb intake to one meal a day. Try where possible to cut out bread and instead eat salad etc. Carbs are burned quicker than protein so if you?re eating lots of carbs you will get hungrier quicker.
Avoid things like mayonnaise and full-fat salad dressings as these contain a lot of calories (100 g mayonnaise contains 500 calries) so by cutting these out you are allowing yourself more calories for your meals iyswim.
If frying foods dry fry them instead of using oil. Oils esp olive oil contains a huge amount of calories (100 ml olive oil contains 900 calories so just one tablespoon for frying contains 150 calories). If possible avoid frying altogether and grill/steam foods instead.
If possible then of course it is better to exercise as this will burn more calories which in turn does mean you can up your calory intake for the days you exercise and will also help with toning.
I lost 10 lb in six weeks by dieting this way and also exercising hard, so it can be done.
Good luck
