How Much Fibre Should I Eat a Day to Lose Weight?

Don't Eat Just Twigs and Berries — a Dietitian Says to Eat This Much Fibre to Lose Weight

While getting in your veggies is a great way to keep calories low if you're trying to lose weight, they're also jam-packed with fibre. But you don't have to just eat veggies all day long in order to lose weight. We asked a dietitian, and here's what she said about how much fibre you need a day to lose weight.

Why is Fibre Good For Weight Loss?

Registered dietitian nutritionist and NASM-certified personal trainer Whitney English Tabaie, MS, said fibre slows digestion and helps you feel fuller longer, which may result in less overeating or snacking between meals, which can lead to weight loss. Fibre also slows the release of glucose into the bloodstream, which helps to maintain energy levels and prevent spikes and crashes.

How Much Fibre Should I Eat to Lose Weight?

The recommended daily amount (RDA) of fibre is 25 grams a day for women and 37 grams for men, Whitney said, but the average American probably only consumes about 15 grams of fibre per day. "I recommend people aim to consume at least the RDA, but really, when the fibre is coming from whole foods versus supplements, the more, the better. Some hunter-gatherer societies consume an upwards of 100 grams a day!" She added to just make sure to consume plenty of water to aid in fibre digestion.

Don't just start eating a ton of fibre if you haven't been! Whitney warns that a drastic increase in fibre, especially coupled with low water intake, could cause digestive distress and constipation. "My recommendation is to increase fibre intake slowly, drink plenty of water, and aim to get your fibre from whole foods versus supplements," Whitney said.

What Are the Best Sources of Fibre?

Great sources of fibre include whole grains, legumes, nuts, seeds, vegetables, and fruit. Here are some ways you can increase your fibre intake:

  • Spread toast with nut butter or avocado instead of butter.
  • Add beans to smoothies, puree into soups, and add to mashed potatoes.
  • Sprinkle hemp seeds on your salad.
  • Use a flax egg instead of a regular egg when baking.
  • Dip carrots or pepper strips in guacamole instead of chips.
  • Add chia seeds to your overnight oats.
  • Bake with whole wheat flour instead of all-purpose.
  • Explore different pasta alternatives such as chickpea pasta.
