Walking after meals can help you lose weight and fat because it can help increase the number of calories you burn. When you eat a meal, your body's metabolism increases slightly in order to digest the food. This process of digestion requires energy, which can be in the form of calories. By going for a walk after a meal, you can increase the number of calories your body burns during this time, which can help you lose weight and fat over time.
One study found that individuals who went for a walk within 15 minutes of finishing a meal had lower blood sugar levels compared to those who waited longer to walk or didn't walk at all. This is because walking can help increase the rate at which your body absorbs sugar from the bloodstream, which can help prevent blood sugar spikes and ultimately contribute to weight loss.
It's important to note that walking alone may not be enough to cause significant weight loss. In order to lose weight and fat, you'll need to create a calorie deficit by burning more calories than you consume through a combination of diet and physical activity. However, walking after meals can be a simple and effective way to boost your calorie burn and support your weight loss goals.
