You should square everything listed below with your physician, or at least get more than a few in LC community to agree.

For your weight, you should have 240 ounces of water a day on average. For your lean mass, you should eat at least 90 grams of protein (and could increase this to near 190 without hazard unless you suffer from gout). You should continue to get no more than 30 to 40 grams of carbohydrates. You should consume about 10 times your goal weight in calories (say 3500 calories), until you get within spitting distance of the goal. So, given these parameters and assuming you do not have gallbladder disease, most of your food will be fat.

3500 Calories
Protein 190g x 4 760 21.7%
Carbos 30g x 4 120 03.4%
Fats 291g x 9 2620 74.9%

A sample of a diet that would not satisfy you for long, but is bound to be towards the inexpensive end is:

grams listed are (carbs)/fats/proteins
1 salad ( 2 cups) a day (4g)/0g/0g
3 oz. cashews (27g)/39g/12g or 6.5 oz macadamias (26g)/143g/13g
26 oz. ground beef (0g)/156g/173g
If cashews are chosen above, must supplement with 1-1/4 cups of whipping cream for (9g)/110g/6g
1 tsp. sweet n low

Even selecting the cheapest LC food around, bad news is that this will cost about $7 a day if you select cashews and whipped cream, and just over $9 a day for the macadamias option. Good news is you can ration down as appetite decreases.

substitute 8 eggs a day for 56g of protein from meat (8g)/40g/56g leaves 8.5 oz ground beef for (0g)/51g/57g, requiring an increase to 2 whole cups of whipping cream (makes a whole bunch of whipped cream (can someone say tijuana brass?)) for (14g)/176g/10g

That saves you about $1 a day.
