But how do our bodies respond?
When you work out to “the point of no return” as I like to call it, ur appetite increases, u become physically & mentally exhausted, u might feel u “deserve” to eat more. U might be too tired to prepare ur own meal from scratch so u order take out or get someone else to cook it
Herman Pontzer, PhD (Hunter College) explained the phenomenon of constrained energy expenditure:
If we push our bodies hard enough, we can increase our energy expenditure, at least in the short term. But our bodies are complex, dynamic machines, shaped over millions of years of evolution in environments where resources were usually limited; our bodies adapt to our daily routines and find ways to keep overall energy expenditure in check.
Non-exercise activity thermogenesis, or NEAT, first described by Dr. James Levine, refers to the calories you burn during physical activities other than sleeping, eating, or structured exercise—things like typing, cooking, gardening, housework, or even just shifting around in your chair.
It may sound trivial, but you’d be surprised at how much NEAT contributes to our daily calorie expenditure. The difference between two people could be as much as 2,000 calories a day. So what you do BETWEEN exercises can affect you more than DURING the exercise.
Diet and exercise are different tools with different strengths. When it comes to losing fat, the food you eat (or don’t eat) is a lot more important than what you do in the gym. But human metabolism is too complex to allow you to manipulate any aspect of it without affecting other aspects.
This is not an excuse for going half-ass or not exercising at all. But focus on increasing strength, endurance, & muscle mass, all of which will contribute to a longer, healthier life, & over time, will get u leaner. Train smarter. Move often.
