is it an unrealistic goal

25lbs in 6 weeks is around 4lbs a week. personally, I think it's not healthy to lose weight that fast. I think 10-15lbs is more doable.

If you're incredibly overweight, it could be realistic. But based on your avatar, I'd say it's probably not realistic for you. Pounds aren't everything though... you could possibly lose enough inches between now and then and look like you've lost that much.

Well that my be possible to do, but its very difficult. Also can be very unhealthy if your not losing the weight in a safe way. So I'm going to say it is a bit unrealistic. Good luck just give your self some more time

A word of warning if you crash diet (with or without bingeing): http://www.myfitnesspal.com/topics/show/3047-700-calories-a-day-and-not-losing

what would you eat????

Enough calories (if you eat a lot normally, I'd have at least 1500 a day even if MFP says otherwise. I eat a lot more than they recommend and I am losing 1-2 lb a week). I posted this earlier for someone else:

- Learn to cook new and simple recipes rather than grabbing ready meals or fast food (e.g. no pizza for lunch).
- Buy a recipe book with quick, easy, simple and healthy recipes.
- Make meals with more of the following ingredients:

Vegetables: green veggies every day (broccoli, salad, beans etc), tomato, beetroot etc. For extra calories, add veggies that are starchy or pulses: potatoes, pumpkin, sweet potatoes, carrots, yams, kidney beans, chick peas, white beans, lentils etc.

Fruit: Banana, orange, strawberries etc all make a good snack. A glass of fruit juice in the morning for example (but no more than 1 glass of juice as it's lots of sugar with no fibre).

An example "ideal" day would be:

Breakfast - 400 calories approx.

1 glass of orange juice (100% natural no added sugar)
2 fried eggs cooked with 1 cal spray oil (spice up with a bit of salt and pepper, or tabasco for a kick).
1 piece of toast

Snack - 100 calories approx.
1 banana

Lunch - 500 calories approx. - Chicken and apple salad followed by yogurt with fruit and honey
1 cup of salad leaves with tomato, sweetcorn, cucumber
1 medium chicken breast without skin
1 chopped apple
1 tsp of olive oil and 1 tsp vinegar
1 yogurt with a tsp of honey, strawberries and almonds

Dinner - 500 calories approx. salmon fillet with zesty creme fraiche
1 salmon fillet fried with 1 cal cooking spray
1 portion of green beans or broccoli
1 portion of new potatoes
2 tbsp of low fat creme fraiche mixed with a zest of lemon

Basically for main meals, try to have half of your plate with veggies, 1/4 with carbs (potatoes/rice/pasta etc) and 1/4 with protein (chicken, lean beef etc).

ALSO DO SPORTS if possible. 30 min 3 times a week is enough. Brisk walking to start with is enough.

I think that's a reasonable, long term suggestion. It's not a quick fix like a low carb diet (they do work well though at first but it's hard to move back to normal eating afterwards for many and they're not more successful long term apparently than calorie restriction) or a crash diet.

If you follow a low carb diet it could help. I limit myself to carbs only once a day and that is usually breakfast occasionally lunch and never dinner. Follow the calorie and fat guidelines that MFP has set for you - lots of fruit/veg/salad and low fat protien is the way I am doing it. For example: breakfast would be porridge, lunch would be a huge salad with canned tuna and a low fat dressing, dinner would be a turkey and vegetable stir fry (I use 200grams of turkey breast for mine and LOADS of veg like mushrooms/peppers)
If you want to snack during the day grab some fruit and the biggest piece of advice is to drink LOTS of water.
I hope you have success xx

Its doable with a very strict diet and extreme exercise, especially if you have a lot of weight to lose. Heck, those contestants on the Biggest Loser can lose 20lbs in a week.

too much too soon. 2 lbs a week is probably the most i would recommend. not to mention that if you set your goal too "high" you probably won't reach it and will feel defeated.
