A Doctor Reveals Whether You’ll Lose More Weight Counting Calories Or By Fasting

Will You Lose More Weight Counting Calories Or By Fasting?

When it comes to weight loss, both calorie counting and intermittent fasting are popular methods—but one may have a clear edge.

"When you spread your calories out through the entire day, you’re actually activating spikes of insulin because every time you eat, you increase insulin. Insulin locks up the fat and it prevents you from burning fat," he says. "When you do intermittent fasting, you’re eating less frequently. Yes, you are eating the same amount of calories but you’re not triggering insulin as frequent. Less frequent eating = less insulin = more fat burning."

The bottom line

While intermittent fasting may lead to more efficient fat burning by reducing insulin spikes, it’s important to remember that no single method works for everyone.

Some people thrive on the structure of time-restricted eating, while others may find it difficult to sustain, especially with busy schedules or certain health conditions. Similarly, calorie counting can be effective for those who prefer flexibility and eating more frequently throughout the day.

Even though fasting may offer metabolic benefits, individual preferences, lifestyle, and how the body responds all play a role in determining which approach is most effective—and sustainable—for long-term weight loss.
