I agree 15 to 20 gms of maximum fat intake should be there .. but when we try to bring this in practicle, it becomes difficult. so here are a few tips to keep a track on your fat intake ...
1] while cooking a meal, count the total number of ppl, say for ex if you are cooking for 4 ppl, thn in one preparation add only 2 tsp oil , 1/2 tsp for each member that way you can control the total fat consumption for yourself as well as your family.
2] dont pour oil directly from the container , use a tea spoon, to keep a count.
3] non stick cookware require less oil.
4]use fat bottomed vessels / kadhai / pan , rather than dome bottomed, you ll save a lot of oil.
