If you're trying to lose weight, experts say try intermittent fasting

Intermittent fasting has become a popular health and fitness trend for those trying to drop a couple pounds. The eating plan is all about timing and only eating certain hours of the day.

Maybe it sounds crazy or challenging, but plenty of people say it’s helped them lose weight and improve their health.

Gisela Long started intermittent fasting two years ago.

“I do the 16:8 intermittent fasting, so I start my day eating at 12 p.m., right after my workout," she said. "Then I end around 8 to 9 p.m. at night. I have lost 20 pounds during that process."

The plan focuses more on when to eat rather than what.

Typically, it’s an 8 hour period, or only every other day.

Studies suggest it can improve blood sugar and cholesterol levels, blood pressure, and weight.

“When done in a healthful way, intermittent fasting can help control inflammation and may even lower the risk of heart disease, type 2 diabetes and some cancers,” said Trisha Calvo , expert with Consumer Reports.

This eating plan is not for everyone, and could be too extreme for older adults, people with diabetes and those who take medications at certain times.

Consumer Reports says incorporating just a few strategies can help with weight and metabolism.

“Be sure to include foods that have plenty of fiber and protein such as fruit, oatmeal, cottage cheese and eggs," Calvo said. "Foods like these will help keep you satisfied until your next meal.”

If you find it hard to resist sweets, Consumer Reports suggests having them before 3:00 p.m.
