The most succinct summary of an "Eat Right & Lift" fat loss protocol, for men & women:
The two best starter books are "Body For Life" by Bill Phillips and "Wendler 5/3/1 version 2" by Jim Wendler (both available on Amazon). Use www.blackirontbeast.com
for a workout program. Record daily food intake at www.myfitnesspal.com
For calories, eat 10x-12x your target weight, but only in 20-25 lb decrements. So, if you're starting at 240: subtract 25 to get the first weight cut target (215). That indicates an eating plan of 2150-2580 calories/day. Start at the high number and drop 100 calories every 2-4 weeks. Every 15-20 lbs you lose, do the math again. Depending on your goals, give yourself 4-24 months for significant change.
For protein: Eat more protein than fats and carbs.. an easy and reasonable target is half your lean body mass, but in grams (so, your average 6'0" male should have around 150-170 lbs of lean body mass, which means 75-85g of protein/day is a good minimum, and double that is a good maximum -- anything in between is perfectly fine). If you believe in high protein diets, then 3x that minimum is the best target (225g protein/day in this example).
That's the easiest, most comprehensive yet least complicated way to get started. If you are working out hard enough, and eating within those guidelines 90% of the time, you'll see progress.
