Not to sound sarcastic, but..your very OWN words have made the most sense, exercise and eat right. Granted, the phrase, eat right is a vey frustating concept to understand, especially with so many pseudo health gurus out there..but...
eating right...yes, of course you can lose body fat....cut sodas, salts, sugars, artifical carbohydrates, etc, etc, etc....you can find AND must find a reasonable approach to fighting body fat. However, for what it is worth, many women have a difficult time keeping off body fat. It is almost a p owerful physiological respone in females, to keep enough body fat for futuristic protection. No one can be more specific, as you wish, because each body IS different. YOu must boldy go where no woman/man has gone before and do some basic research as to what foods, life behaviors, emotional causes, contribute to you gaining weight, etc.
Or, are you sure you are even FAT? or...are you following some ridiuclous b.s. magazine or pop culture news broadcast...conditioning your brain, telling you that you are fat..when possibly, you are a normal weight. Specifics? Ha..ok...here is one specific: NEVER GET SUCKERED INTO trying the stupid quick fix diets....they are never part of your regular life system, your life behavior, your way of living..
you must find some sort of DIET, EXcerise...mental health, philosophy to live by, over time, to continually MAKE a slim, healthy body a normal everyday part of your KARMA, total being. Without this, sorry sis....it's fat farm city for you.
