Self-reported average energy intake of 2,640 calories for men and 1,785 calories per day for women is within current USDA recommendations, yet still higher than our previous generation. Since the majority of men and women in the U.S. are overweight or obese, many are eating more calories than they require. With the more convenient from a modern lifestyle such as car, dishwasher, vacuum robot we are less active (and weaker) than our ancestors.
Normally, a person’s energy expenditure becomes less as they get lighter, it means that you will inevitably plateau.

This will help most of us reach a weight loss plateau.
