What’s the deal with carbs and calories?

One gram of carbohydrates offers 4 calories. The thing is that staple foods such as bread are calorie rich and offer calories since these are dense in carbs. About 100 g of pasta offers 131 calories, white rice offers 130 calories per 100 g, brown rice offers 111 calories per 100 g, etc.

Even healthy foods like oatmeal contain a good amount of calories. Calories are not a bad thing. They are the fuel for your body. Your body cannot function without this fuel. Processes like DNA synthesis, metabolism, waste removal, immunity, etc, require energy and energy means calories. An adult woman must consume 1600 to 2400 calories per day, and an adult man must consume 2000 to 3000 calories per day.

The issue with a high carb diet

High carbs or high sugar levels block the activity of insulin (insulin is a hormone that reduces blood sugar levels). This affects metabolism. The liver gets excessively loaded with these sugars and will convert them into fat. Consumption of high amounts of sugar especially fructose will result in belly fat build up.

This does not mean you exclude calories. Instead, you can restrict them from an excess level of consumption. Refined sugars or “white carbs” like wheat, rice, pasta, bread, soft drinks, etc., are some of the common sources for this condition.

During such cases, your body responds by lowering the blood sugar levels but lands up overdoing it and this results in a sharp dip in the blood sugar or energy levels. Finally, you feel more tired and hungry and this leads you to eat more. When you eat more, you consume more carbs or fat and this surpasses the capacity of the cells and liver to suppress the high blood sugar levels. That is why you tend to put on weight.

Too many carbs mean a surge in the blood sugar. Normally, when you eat any food, during carbohydrate digestion, the absorption of glucose into the bloodstream will result in spiking the blood sugar levels. Now, a hormone called insulin reduces the blood sugar levels by directing the cells to take in the glucose. If the intake of glucose flares up beyond the capacity of the cells,  the insulin directs the liver to convert this excess glucose into a storage form of energy sugar called glycogen.

If the sugar levels go beyond the capacity of what the liver can store, then the insulin will signal the liver to convert the excess glucose into fatty acids. It also directs the fat cells to terminate the fat breakdown. So, on one hand, it is the liver building the fat and on the other, the fat cells stop their function of utilizing fat for energy.

Too much of carbs means digestive problems

low carb foods nutsThere are fiber-based carbohydrates as well. They are very helpful but consuming such sources in excess isn’t good either. Fibers are very useful in bringing down your blood sugar levels. They slow down the digestion and absorption of carbs and thus prevent the sudden spike in the blood sugar levels.

Consuming such fibers will also make you feel full for a long time and beat the incidence of any cravings or tendencies of eating more. These fibers absorb water and form a gel-like substance and this is the underlying base for loosening your stools and ease in your bowel evacuation.

Too much of these carbs based fibers isn’t good either. If you suddenly start taking these fibers in large amounts, you will experience flatulence, bloating and stomach discomfort. It can also make your stool too lose and result in diarrhea. Also, if you don’t consume much water upon a fiber intake, it can dry your stools up and result in constipation. This does not mean you should refrain from eating such fiber based carbs. You can consume them in moderation. You can begin with 5 grams and build on it every 2 weeks. The maximum limit must be 25 – 35 grams/ day.

Chlorogenic acid prevents the oxidative damage of the bad cholesterol and also reduces its levels in the blood. Chlorogenic acid also amplifies the insulin sensitivity and it helps in treating type 2-diabetes (a condition of high blood glucose levels caused due to insulin resistance).
  • The polyphenols in brinjal also have an anti-cancer trait and this helps in preventing the growth and spread of cancer cells.
  • The anthocyanins in eggplant prevent any inflammatory reactions in the brain and prevent any age-related damage. It improves the cognitive abilities of individuals.
