8 Surprising Foods One Should Never Eat When Trying to Lose Weight in 2017

Yes, everyone needs fiber — it keeps your digestive system churning and keeps you feeling full, even when you’re cutting back on calories. What you don’t need: Nearly one day’s worth of fiber (about 25 grams) in one snack bar, with a diet that’s otherwise devoid of it, Harvest says. “Fiber intake has to be consistent throughout the day to stave off hunger, improve digestive health, and not cause stomach upset.”

Eat This Instead: Produce that’s naturally rich in fiber — any fruit or veggie will do. Make produce a part of every snack and meal you eat throughout the day, and you’ll get your daily dose of filling fiber, no problem.
