I was told by a very good physician once, that we should only eat what was available two hundred years ago. A lot of our foods are over-processed today.
White rice-eat brown rice, all the good stuff is processed out of the white leaving only simple carbohydrates.
White bread-eat whole grain bread.
White pasta-eat whole grain pasta.
Soda pop.....WTF are you thinking, drink water, fruit juice (whole), tea, wine, beer, whiskey, anything but soda.
Fast food-nope cook a real meal, or eat fruit, or a salad.
Plus exercise does make a huge difference. All my adult life I weighed 155-165lbs. At 6'1" I ate everything I could, trying to get to the "optimum 180lbs". I worked at a fairly physical job 40-50 hrs/week, plus another 20-30hrs/week in the garage building cars, plus training martial arts 7-8 hrs/week.
After hurting my back, and spending 20-22 hrs a day prone, I hit 200lbs in THREE MONTHS. I was fat as a pre-teen approx 50lbs overweight. Eat less exercise more works. But eat less of better stuff, exercise more works better.
Oh yeah, now I'm at 185lbs.
