Is calorie expenditure the main factor in obesity prevention?

Preventing obesity depends on the balance between how many calories you eat and how many you burn. This is called energy balance.

Key Points:

1. Energy Balance: To keep a healthy weight, you need to balance the calories you eat with the calories you use. If you eat more than you burn, you might gain weight.
2. Calorie Expenditure: Being active helps you burn calories. But, just focusing on burning calories isn't enough by itself.
3. Lifestyle Factors: It's important to look at your whole lifestyle, including what you eat and how active you are, to prevent obesity.

So, while burning calories is important, it's just one part of the bigger picture. Making sure you're eating healthy and staying active are both important for keeping a healthy weight.
