I'm trying to save more too. I spent the most during lunch even though I eat at coffeeshop. A typical lunch at coffeeshop would be:
Rice + dishes or chicken rice or fish soup - approx $3 to $4
Fruit - 2 slices at $1.20 in total
Hot drink - 90 cents now
Snacks like bun, egg tart etc. - $2
As my family does not cook, I spend about $20 in total per day. Including weekends where I eat better (like tze char, no restaurants for me), I still spend about minimum $500 on food!
Therefore, my monthly expenditure goes like this:
Food - $500
Transport - $100 approx
Insurance - $200 (ILP and health plans)
Household (mom keeps this) - $100
Mom - $100
Dad - $100
HP - $60
Broadband - $33 approx
Miscellenous - $50
Food
Break $1 (eat bread with butter)
Lunch $3 (no drink allowed)
Dinner $3 (no drink allowed)
Total $7 per day.
Total $210 per month (30 X7=210)
Internet ( M1 mobile broadband= $16 per month)
HP ( $30 per month )
Total so far (210+16+30=256)
Transport(120per month + 256 = 376)
Therefore... possible... but... whether u are comfortable.. if u are not use to this kind of spending. Especially $3 per meal... for 30 days...or more...
