Fibre is why you are bloated and still hungry

Protein gets all the attention on a vegetarian diet, and it should. But when a client tells me they are following the plan and still hungry all afternoon, or that they feel heavy and bloated every evening, protein is usually fine. Fibre is the thing nobody looked at.

It cuts both ways, which is what makes it confusing. A traditional Indian vegetarian diet built on dal, sabzi and whole grains can be genuinely high in fibre. A modern one built on white rice, refined roti, paneer and protein shakes can be surprisingly low. On a diet, both create problems.

What fibre actually does on a cut

• •It fills you up for very few calories. Fibre adds volume and slows stomach emptying, so the same calories keep you full longer. On a deficit this is the difference between manageable and miserable.
• •It blunts the blood sugar spike from a carb-heavy meal, which flattens the crash and craving that follows two hours later.
• •It keeps digestion regular. Cutting calories usually means eating less food overall, and constipation on a diet is extremely common.
• •It feeds your gut bacteria, which matters for how comfortable you feel day to day.

How much do you need?

The usual target is around 25 to 30 g a day for women and 30 to 38 g for men. A simpler rule that works for most people: 14 g per 1,000 calories you eat. On 1,600 calories that is about 22 g. On 2,200 it is about 31 g.

Notice what that means on a cut. As your calories come down, your fibre target comes down with it, but your hunger goes up. So the goal is not maximum fibre. It is hitting a reasonable number from foods that carry it alongside protein.

Where vegetarians actually get it

These are per typical cooked serving, and they are the ones worth building around because they bring protein too.

• •Rajma, chana, kala chana, one katori cooked: roughly 7 to 9 g fibre, plus 7 to 9 g protein.
• •Moong, masoor, toor dal, one katori cooked: roughly 4 to 6 g fibre, plus 7 to 9 g protein.
• •Sprouts, one katori: roughly 4 g, and they are mostly water so the calories are tiny.
• •Vegetables, two katori of anything green: roughly 4 to 6 g for almost no calories.
• •Oats, 40 g dry: roughly 4 g, and the soluble kind that helps with fullness.
• •Chia or flax, one tablespoon: roughly 4 to 5 g.
• •Whole fruit with the skin, one apple or guava: roughly 3 to 5 g. Juice has essentially none, which is why it never fills you up.

Why you are bloated

Nine times out of ten it is not that fibre is wrong for you. It is that you went from 12 g a day to 35 g in one week because you started a diet on Monday. Your gut bacteria need time to adjust, and the adjustment period is gas, bloating and discomfort.

• •Add it gradually. Roughly 5 g a week, not all at once.
• •Drink more water. Fibre without enough water makes constipation worse, not better. This is the single most common mistake.
• •Soak and cook your legumes properly. Soaking rajma and chana overnight and discarding the water removes a large part of what causes the gas.
• •Spread it across the day rather than eating one enormous dal-and-salad meal at night. Evening bloating usually traces back to an evening fibre dump.
• •Give it two weeks before deciding it does not agree with you. Most people adapt.

If you have genuine IBS, this advice changes and is worth a conversation with a doctor rather than a coach. Certain high-fibre foods are common triggers and the usual "just eat more vegetables" answer can make things worse.

A simple day that gets there

• •Breakfast: oats with a tablespoon of chia and a banana. Around 9 g.
• •Lunch: one katori rajma, one katori sabzi, two rotis. Around 14 g.
• •Snack: a guava or an apple, and a handful of roasted chana. Around 7 g.
• •Dinner: dal, a large salad, small portion of rice. Around 9 g.

That is roughly 39 g without trying, and it is ordinary Indian food. If your day looks nothing like that and you are hungry all the time, you have probably found your problem. Our recipe library is built around exactly these ingredients, so the fibre comes along with the protein rather than being a separate job.
