i got this off a website and it DOES mention that this plan might help some people lose weight...but im posting it because 1000 cals would be amazing for some of us to get up to! so here are sone reasons y 1000 cals might not be such a bad idea:

The 1000 Challenge

Benefits of raising daily calories to 1000 calories a day:
- your metabolism will be much faster and you'll lose more weight. When you eat too little you burn muscle, and the more muscle you have the faster your metabolism. Also the body slows the metabolism so that it needs less calories to carry out normal functions - breathing, movement, making cells etc.
- you'll be less likely to binge. When restricting or when your weight is lower than it is supposed to, your body sets up cravings for fatty sugary foods.
- you'll burn much less muscle for energy. When restricting or fasting, as much as 90% of weightloss is from muscle. This muscle can include heart muscle (which can cause heart failure) and other important muscles (i was once in contact with a bulimic who was incontinent because the muscle that held in her urine had been burnt for fuel).
- You'll be generally more healthy - less likely to have vitamin deficiencies and so on.
- you'll have way more energy.
- you'll appear more 'normal' to loved ones, and it will prevent them from worrying so much.

The best way to get to 1000cals (or a higher number if you like) is to add 100cals to your daily intake every week. You can go straight to 1000cals, but if you do you might gain a lot of water weight. Remember, it's very unlikely you'll gain any actual weight doing this - any weight-gain will be just water.

Some people struggle to get to 1000cals because they don't know what to eat, as they usually eat such low-cal food, so here's some suggestions:
-carbs (they're not THAT evil - remember that asians use white rice as a staple in their diet, and they remain slim) - wholegrain bread, wholewheat pasta, potatoes, sweet potatoes, brown rice.
-protein - meats, beans, tofu, rolled oats, dairy products, eggs, soy products, nuts and lentils.
-fats - i know they are really REALLY scary, but some are actually good for you! olive oil is okay, as is canola oil.
- some people have the control to eat small quantities of junkfood and therefore could make up their cals with a small amount (bear in mind it's much healthier to eat 1000cals of chocolate a day than it is to eat 400cals of veg!!)

If you gain on the challenge (this is possible if you are small or have severe metabolic damage) and you have been on the challenge and building up calories correctly (adding 100 per week) then try either of these alternative plans:

-do a variation of the 2-4-6-8 which is 6-8-10-12, this will stir the metabolism into action. Any other plan which fluctuates the amount of calories will work too, as long as the average daily calories are around 1000.
-drop your calories to 900 or 800cals. If you do this a higher proportion of your calories has to be from protein and it's a good idea to try and build muscle too, and this will help avoid muscle wastage when you do start to lose weight.
