Eat carbs, lose weight: How carbohydrates can help you eat less AND burn more calories
For years they’ve been a no-no — but now a diet taking America by storm says bread, pasta and potatoes can help you drop half a stone in a week...
But, as anyone who has tried one can testify, there is something about carbohydrate denial that seems extraordinarily punishing.
Carbs are, after all, so tempting —whether it’s the smell of freshly baked bread or the delicious sight of buttery new potatoes.
But the low-carbohydrate message has become so entrenched in modern diet wisdom that pasta, bread, rice and potatoes have been widely accepted as being intrinsically ‘bad’.
But does it have to be this way? A new diet plan claims not, positively encouraging its followers to eat spaghetti and jacket potatoes with meals yet claiming it’s possible to still lose up to 6lb in a week.
It goes against everything we’ve been told by the likes of the Dukan and Atkins diets, but studies have shown that not all carbs are bad. Some contain a substance called resistant starch which, when consumed in quantity, actively encourages weight loss.
Found in ordinary foods — such as bananas, oats, beans and potatoes — resistant starch is so-called because it appears to resist digestion.
This starch travels through the digestive system nearly intact, producing fatty acids that stimulate fat-melting enzymes (particularly in the abdominal area), encouraging your liver to switch to a fat-burning state, preserving muscle mass (so stoking up your metabolism) as well as boosting satiety hormones, meaning you feel fuller for longer.
Now, the power of resistant starch has been harnessed in a book, The Carb Lover’s Diet, which has taken the U.S. by storm and is now available in the UK. Written by respected health editor Ellen Kunes and dietitian
FOOD FOR THOUGHT
A U.S. study found women who ate a low-carb diet had a poorer memory and attention span than those on a low-calorie diet
Both authors are vehemently against the low-carb message, believing Atkins-style diets are difficult, unnatural and ineffective long-term. They claim our bodies and brains have evolved to eat starchy foods and willpower alone can only hold back on centuries of evolution for so long before we crack and all those good intentions are lost to a carb-rich feeding frenzy.

Research at the University of Surrey found that consuming resistant starch in one meal caused participants to consume 10 per cent fewer calories (roughly 150 to 200 calories for the average woman) during the next day because they felt less hungry.
Another study showed that resistant starch increases the activity of fat-burning enzymes and decreases the activity of fat-storage enzymes, meaning stomach-fat cells were less likely to pick up and store calories as fat.
Results seem to indicate that adding a little resistant starch to your morning meal is enough to shift your body into fat-melting mode, enabling you to burn nearly 25 per cent more calories a day.
Meanwhile, you’ll eat about 10 per cent fewer calories because you don’t feel as hungry. Most of us naturally consume around 4.8g of resistant starch a day, but the authors believe increasing your intake to ten to 15g a day is enough to trigger a swift and simple route to weight loss.
They have devised a quick-start, seven-day diet plan which, they say, guarantees rapid 3lb to 6lb of weight loss, and a separate long-term strategy for incorporating healthy carbohydrates — particularly those containing resistant starch — into your life to ensure weight continues to come off, and stays off.
STAR CARBS
- BANANAS are your richest source of resistant starch. They are also rich in appetite-suppressing fibre (3g each) and contain the amino acid tryptophan, which is converted into the calming brain chemical serotonin to help you relax and improve your mood.
- Nearly half the starch in BEANS is resistant starch, making them a powerful weight-loss ally. They are also an incredibly rich source of fibre. A Canadian study found that people who ate beans regularly tended to weigh less and have a smaller waist than those who didn’t (they were also 23 per cent less likely to become overweight over time).
- In addition to the fibre and resistant starch they contain, POTATOES are a natural source of a proteinase inhibitor — a natural chemical that boosts satiety hormones and curbs appetite.
- POLENTA — this cooked cornmeal is naturally high in resistant starch, but is also rich in fibre and contains a decent amount of protein. It can be cooked into a creamy consistency or baked into crunchy sticks (chop small to make nutritious crutons).
- BROWN RICE digests more slowly than white. One study found that blood sugar levels were 24 per cent lower in people who ate brown rice than those who ate white.
- BARLEY is rich in resistant starch and both soluble and insoluble fibre which reduces appetite and aids digestion.
Stick to the daily plan (below) or mix and match meals, but to lose weight quickly, follow these rules:
- Eat at least 1g of resistant starch with each meal and aim for a minimum daily 10g total.
- At lunch and dinner, ensure resistant starch fills a quarter of your plate and the remaining three quarters is lean meat and low-fat dairy products, fruit and vegetables.
- Write down everything you eat in a food diary, highlighting all foods high in resistant starch (research shows that dieters who jot down what they ate lost weight more quickly than dieters who didn’t, and keeping a food diary helps dieters follow their plans without cheating).
- Ban artificial sweeteners. Studies show they may increase your cravings for sugary foods. Fake sweeteners are up to 600 times sweeter than sugar and numb your taste buds to the natural sweetness of good-for-you carbs such as berries and other fresh fruit.
- Eat one snack a day to prevent between-meal bingeing (the longer you wait to eat your snack, the easier it will be to stick to the diet).
- Don’t skip meals. Sticking to a regular pattern maintains blood sugar levels and keeps hunger at bay.
- Keep trigger foods out of the house. This means you are less likely to lose your self-control and scoff them down.
- Drink eight glasses (240ml) of water each day, so you don’t mistake thirst for hunger. Don’t drink liquid calories. On the seven-day kickstart plan, you can drink water, coffee and tea (black, green or herbal, without sweeteners, but with up to two teaspoons of semi-skimmed milk), but skip fruit juice, alcohol and fizzy drinks (even diet drinks or sparkling water), which make you look and feel bloated.
- Sit down to every meal. Grabbing something and eating it over the sink sets you up for overeating. It doesn’t give you a chance to be mindful about your food, and you’re less likely to pay attention to the serving size. Eat slowly and avoid TV, music and even dinner companions — all of which can cause you to overeat.
- Use smaller plates (try your salad plate instead of your dinner plate) and keep portion sizes small.
- For a quick boost, try this fat-flushing cocktail, which includes metabolism-boosting ingredients that will help speed you to your goal: Take two litres of green tea, juice from one orange, juice from one lemon and juice from one lime. Mix together in one large jug. Serve hot or iced. Keep in the fridge for up to three days.
