How to increase Fibre on a healthy Low Carb Diet – avoiding constipation

Fibre Foods are essential on a healthy Low Carb Diet

How do I get it right?

Fibre comes from vegetables, fruit, nuts, beans, wholegrains and it can also be supplemented using the likes of psyllium husks or Slippery Elm.

When you change your diet, you might notice a change in your toilet routine. On a low carb food plan you will loose weight and experience little to no sugar cravings but you need to eat fibre levels of 18g to 30g per day to avoid constipation and keep the bowels healthy.

Let’s look at how to reach your fibre levels

25g Oats (16C) -2g80g pepper (2C) – 2g80g broccoli (1C)- 3g40g celery (1C) – 1g
25g Oat bran (13C) – 4g80g lettuce (1C) – 1g80g carrots (6C) – 3g30g Nuts (2C)- 2g
80g Spinach (1C) – 2g80g tomatoes (2C) – 1g80g cauliflower (2C) – 2g11g Linseeds (2C)- 3g
160g mushrooms (1C) – 2g80g raspberries (4C)- 3g
43g Nutty Granola (5C) – 6g85g apple skin (8C) -on – 1g
50g Keto Bread roll (2C)- 6g
5g Psyllium Husk – 4g
4g to 6g4g8g10g

The above day provides 3 breakfast options – a cooked breakfast, porridge or my nutty granola. The whole day provides 26g to 28g fibre and a total carbohydrate intake of 31g to 60g Carbohydrate plus proteins and fats. My Low Carb eating plan includes 5 to 7 servings of low-starch vegetables a day (5 x 80g) per day along with oats, wheat & oat bran and psyllium husk.

You are the best person to know what your bowel needs to stay healthy. If you need porridge, have it, just log it on the APP. The bottom line is, do not get constipated on a low-carb food plan.

Fibre is absolutely essential for 2 reasons

1. Fibre moves food waste products and toxins out of the body.

2. Fibre feeds gut bacteria.

Gut bacteria feed on fibre to produce acids (butyric, propionic and acetic) and these acids reduce cholesterol and insulin spikes.

Warning: For people with diagnosed IBS, SIBO, who are likely to have an imbalanced gut bacteria, fibre can cause excessive bloating, wind and make them feel very unwell. A very low carbohydrate diet and the FODMAP diet are excellent regimes to trial and see if you get relieve and a management tool to help the gut recover.

Top Tip – Know your 7 types of fibre and find out which work best for you by trying recipes and seeing the effect they have on your bowel over a few days.
