> They need to live more active lives.

When I become more active, I also become more hungry due to the extra energy consumption. The net effect is little weight loss and more often than not weight gain. While being physically active is beneficial to health in many ways, it does little for losing or maintaining weight, at least for me.

deficit = tdee - intake

Active life = higher TDEE which means you can eat more food while still maintaining same deficit.

Exercise also stimulates digestion and triggers a hunger response in many people. This is why exercise without diet often fails to result in weight loss.

People overestimate calorie burn from exercise.

For example, a lifting session may burn 200-300kcal and then they'd think they've burned a lot, so they will end up eating 500kcal back.

so as a result there is no deficit there.

Exercise typically doesn’t cause people to eat because they are confused about estimating caloric expenditure, it causes them to eat by inducing hunger.

Even people who track their calories perfectly often eat when hungry because it is the most basic of human instincts and our brains and bodies are wired to respond accordingly.

Higher physical activity does not always boost hunger, it can have hunger suppressing effect too.

>Even people who track their calories perfectly often eat when hungry because it is the most basic of human instincts and our brains and bodies are wired to respond accordingly.

Many people can track calories, hardly any of them are tracking calorie burn and no the ones from your watches or displayed on cardio devices aren't correct.

Many times the eating more issue you are seeing is because average guy may estimate that 1 lifting session burns 800-1000kcal. How do i know? i've asked random people in gym this question.

		Obesity also doesn’t affect everyone. But within that group, we’re typically talking about the people who do tend to have more eating triggers than people who are not obese. It is hard to accurately calculate the calories burned in a lifting session but the ability to count calories has little to do with the causes of obesity. Even if a person could count them perfectly that doesn’t mean they are capable of manipulating the numbers to meet their goals.
