Break the hungry cycle

The amount of food we eat is influenced by various things like culture, availability of food, calorie-dense nutritionally poor foods, habit, cost of food, stress and emotion. We also eat when hungry. It is hard to resist the sensation of hunger. Hunger is the signal to our bodies to re-fuel, and it is regulated biochemically. Unfortunately, sometimes the biochemical system can be upset, leading to extra appetite for food even when we have actually eaten enough.

When things are working without a hitch, hormones signal to the brain to either stimulate or supress appetite. But when the system gets disrupted, hunger keeps on nagging. We eat more, the system gets more upset, we get hungrier, we gain weight, and so on.

There are many chemicals including hormones which communicate with the brain to regulate the system. A few of the key hormones involved are ghrelin, insulin, and leptin. Hormones  provide controls and messages for the body’s cells and organs.

Ghrelin is produced in the stomach. An empty stomach produces ghrelin, which signals hunger to the brain. It is time to eat.

After eating, insulin is produced in response to increased level of blood glucose (sugar). It is the hormone that signals the body to store energy from food as fat. Thanks to insulin blood sugar is sent to our fat cells to be stored for later. If we eat foods that dump large amounts of glucose into the bloodstream (foods like added sugar, white bread or pototoes, or drinks like juice or sodas) then we get a much bigger amount of insulin released to send the glucose into our fat cells. Subsequently, there is a crash in blood glucose, which makes us feel hungry again.

When things are working properly, insulin levels go up after eating, and leptin is released from fat cells signalling to the brain that we have eaten enough.

But if we eat foods with added sugar and without fiber on a regular basis our bodies are constantly producing large amounts of insulin in response. This has the damaging effect of making the cells of our body resistant to the effects of insulin, which means we produce more and more insulin to compensate. This may lead to pre-diabetes, then diabetes.

With high levels of insulin comes high levels of leptin. Leptin tells us to stop eating so it should be a good thing. Unfortunately, it seems that with high levels of leptin we also become leptin-resistant, which has the effect of making us feel the need to eat more and expend less energy.

To keep your appetite functioning normally avoid eating anything with added sugar, minimize eating white bread, white rice, white pasta, foods made with white flour, and potatoes. Stick with high fiber, wholegrain foods. You will find that feelings of hunger decrease. If you want a snack between meals eat a few nuts or a piece of fruit.

  1. This has just been confirmed by research at Harvard that analysed the eating habits of over 100000 adults that shows that the average adult gains over 1 lb every year over the 20 years of the study and that starchy foods, refined carbs and processed foods were all most associated with weight gain and vegetables, other than potatoes, were associated with weight loss as were fruit, nuts, whole grains and yoghurt

  2. Calories are the basic unit of energy found in all foods and are necessary to maintain the body’s vital functions or basil metabolic rate. The amount of calories a person needs depends on factors like their age, gender, and lean muscle mass. Eating too few calories for a prolonged period of time causes a person to become underweight (per the BMI) leading to muscle atrophy, weakened immunity, and eventually, organ failure.,
