Yes, but I didn't say "every day". In any case, it definitely is a LOT easier to take in calories and gain weight than it is to burn calories and lose weight. According to the chart I posted earlier, if one were 164 lbs and walked 5 miles at 2 mph they would burn about 600 calories, about the caloric content of a glazed doughnut. That unfortunate mathematical relationship is the biggest problem.
The key is regular vigorous exercise, when kids got that every day there were very few fat ones. There were very few fat adults either. Watch some movies from the forties and fifties, it is amazing how skinny people were. I don’t think it was because we all were on strict diets.
