First thing you need to do is throw the scale away , it will start fucking with your head.
Second things is dont expect to not lose some muscle , especialy if your cutting your calories way back and not taking in enough protein , your body cant burn bodyfat fast enough so it will turn to muscle for added energy , after a while your weightloss will stall due to the low cals and forcing the body to feed off itself it will slow down the metabolism
2500-2700 clean cals a day should keep you in a safe zone with keeping metabolism up and providing enough energy to.
Us a simple , afternoon carb cut off approach
meals 1-4 , 50g pretein , 30-40g carbs , only trace fats (5-8g)
Meals 5-6 , 50g protein , trace carbs from dark green veggies , 15-20g fat from red meat or nut oils
Eating clean doesn't have to be real expensive , look at it like this
if you eat fast food 2x a day thats gonna cost you about $10-$12 min , chicken breast is $2 a pound , lets say your cheap and get a happy meal
for $10 you can get 4 pounds of chicken
that 64 oz , devided by 6 meals is bout 8oz per meal cooked , their about 6.5g protein per ounce of cooked chicken (conservitive) thats 52g protein per meals 6x a day , so their is NO need to cut your protein out cause its to expensive
Rice is retarded cheap 5 pounds will last weeks , theirs your carb source
Omega-3 eggs can be had reasonably cheap as well , 3 whole eggs in the last 2 meals a day will provide your fats , and a dozen eggs will last you 2 days ($2 a day)
Stop by costco , or Sams or whatever and stock up on frozen veggies , you can get bigger bags that will get you 3-4 meals worth for a couple dollars.
Sit back and look at what you waste money on , eating out , snacks , going over on your cell min , driving excessivly fast ofr making uneeded trips burning gas
