Lighthearted facts Clear. program
Nearly 300 participants have already joined the Clear. Nutrition program. On average, each participant collected over 1400 data points during the program, including glucose measurements and logged meals and exercises. We gladly give you some insight in our database and, in contrast to all serious news reports over the last weeks, provide you with some lighthearted facts. Food Everyone responds differently to foods. Clear. helps to und
Scientific base for The Clear. Health Program
There is no discussion that a healthy diet is essential for obtaining and maintaining good human health. The WHO provides a definition of ‘a healthy diet’1, and from a scientific point of view, there is ample evidence that dietary factors are recognized contributors to common diseases, like obesity, type 2 diabetes and heart disease2. Despite scientific substantiation of many diets and attributed benefits to general health or prevention of disease, there is no evidence based ‘diet that fits al
Hormones and glucose during women's period / cycle / menstruation
In a recent publication of The International Journal of Eating Disorders, Professor Kelly Klump explored the relationship between the menstrual cycle and hunger. During ovulation, few women experienced binge eating. The period after ovulation until menstruation turned out to be the period when many women lost control of their eating behavior. As menstruation got closer, this feeling became stronger and stronger. This feeling of hunger
Life hacks for a stable blood sugar level
How to stay healthy and fit during this period of targeted lock-down? It starts with keeping your blood sugar levels stable. In this newsletter, we describe various tips, tricks and life hacks. We are now in the fourth week of the targeted lock-down. The motto is still: stay inside as much as possible, only go out for essential groceries and some fresh air. It remains special: a period without restaurants, bars and gyms. How do you stay fit indoors, how do you ensure that you do not gain a
Personal glycemic response
The glycemic index is a ranking of foods based on how they affect blood glucose. It is a standardized tool (based on the average effect of food in a large study population) to understand / predict how food affects blood glucose. However, there are some limitations because this index does not take into account: Interpersonal variability: Different people who eat the exact same meal can have highly variable glucose responses, due in part to their body's unique and complex biological environm
High-carbohydrate versus low-carbohydrate diet?
There are many studies that show that low-carb (and high-fat) food ensures more stable blood sugar and better energy balance, and more control over weight management. So it is definitely worth trying how your body reacts to that. It is important to remember that there are many complex carbohydrates and healthy protein sources that can help our body function optimally and may not generate significant glucose and insulin peaks. So it is not wise to eliminate all carbohydrate-rich food sources in a
Glucose response as a measure of insulin
Glucose values reflect the insulin response. Knowing how much a particular food raises blood glucose provides insight into the body's expected exposure to insulin. This gives an idea of whether the body is likely in a fat storage or fat burning mode.
Will my blood sugar levels differ due to menopause?
During menopause, estrogen and progesterone levels decrease significantly, affecting a number of regular bodily functions. One of the effects that these lower hormonal levels have on the body’s cells is that they change the way cells respond to insulin. In most women, this will result in higher levels of blood sugar. In some women, there will be fluctuating levels of blood sugar.
Why do I get hungry?
Hunger can roughly arise in two ways: 1) when you need nutrition, and 2) when there is a certain condition. Hunger is being regulated by the 'hunger hormone' called ghrelin. This hormone stimulates the appetite. This hormone opposes leptin, the satiety hormone. When we go without food for days, ghrelin will send a signal that food is needed to survive. This happened especially long ago, when we were still hunters / gatherers. At that time we did not have access to food every day. Today we ofte
Insight through glucose measurements
Real-time glucose measurements provide insight into how food affects blood glucose levels, providing indirect and approximate insight into insulin levels. Unlike traditional dietary strategies such as calorie counting - which have been shown time and time again to be ineffective for long-term weight loss - glucose monitoring provides insight into the underlying physiological processes that lead to fat storage.
Welfare Diseases (part 1): Obesity
We are increasingly confronted with conditions such as obesity, diabetes, cardiovascular problems, joint pains and psychological problems even at a younger age. The cause and the increase of these so-called welfare diseases is attributed to societal and technological changes. The development of fast and cheap production processes, unlimited access to (online) facilities, and more sedentary professions. This has led to an increase in factors such as perceived stress, sleep deprivation and polluti
Diets and the effect of leptin (satiety hormone)
In addition to insulin, there are also other hormones that play a major role in weight management. Leptin is one of the appetite suppressant / satiety hormones. It is secreted by fat cells in response to food. As fat mass increases, the level of leptin increases. Probably, leptin signals to the brain that the energy requirement is saturated, and that food intake must be inhibited to prevent over-consumption of nutritional energy. Leptin suppresses insulin production, thereby inhibiting fat stora
The Coronavirus (COVID-19)
The Corona virus is holding us captured. Many of you, just like us at the Clear. team, work from home and others are busier than ever in a position in healthcare or in other vital processes. Everyone is affected by the impact of the measures on daily routines and the concern and uncertainty about the course of this crisis. You may be more than usual aware of your health, your resistance and how to stay in shape, especially now that all sports facilities are closed. Therefore in today's Clea
Obesity as a risk factor in corona
Week 3 of social distancing With each new day of the corona pandemic, the total numbers of infections, hospitalizations, deaths and recoveries increase. And with each increase in numbers, there is more insight. In the infection rate, the ratios of admission and death, the risk factors for serious complaints or IC admission, and the chance of building up immunity without serious complaints. We devour the numbers. We want to know. To understand, to learn, to reassure ourselves or others, and
Insulin sensitivity and insulin resistance
During digestion, carbohydrates are broken down into smaller sugar molecules (glucose), which are absorbed into the blood. When the glucose level in the blood increases, the body will release the hormone insulin. Increased insulin levels lead to fat storage and weight gain. If glucose is constantly increased due to diet or lifestyle factors, insulin production will also be constantly active. This allows our cells to become 'numb' to insulin. This is called insulin resistance. It means that more
