Focus on Fibre
"Eating high-fibre foods will keep you fuller longer on fewer calories," Rachel said, so aim to fill up on at least 25 grams a day. Go for veggies, fruits, whole grains, beans, nuts, and seeds. Soluble fibre, in particular, can help with weight loss and has been shown to help reduce belly fat, Rachel explained. "A research study in over 1,100 adults found that every 10-gram increase in soluble fibre was associated with a 3.6 percent decrease in belly fat," she said. Foods high in soluble fibre include legumes, apples, brussels sprouts, avocados, and flaxseed.
