Ces habitudes du week-end peuvent faire monter les triglycérides, et beaucoup le font sans réfléchir.

Over the weekend, many people indulge in habits they might otherwise avoid during the workweek, late nights, excessive drinking, snacking, and sleeping in. However, these seemingly harmless activities could actually contribute to elevated levels of triglycerides, a type of fat found in the blood that, when consistently high, can increase the risk of heart disease and stroke. Experts warn that even routine weekend behaviors can have measurable effects on triglyceride levels, often unnoticed by individuals who consider them benign. Triglycerides serve as energy reserves for the body, storing excess calories not immediately used. While some level of triglycerides is necessary, their accumulation can lead to health complications. According to Dr. Brett A. Sealove, a cardiologist, the body uses triglycerides as fuel between meals and stores extra calories as a form of “energy savings account.” When triglyceride levels rise beyond normal ranges, this can signal underlying metabolic issues. The American Heart Association classifies triglyceride levels above 150 mg/dL as elevated, with higher thresholds indicating greater risk. One common weekend habit that contributes to increased triglycerides is alcohol consumption. Even moderate drinking over a few days can affect how the liver processes fats. As Sealove explains, the liver prioritizes breaking down alcohol over other substances, which slows the metabolism of fats and leads to increased production of triglycerides. This effect is compounded when alcohol is consumed alongside sugary drinks, fatty snacks, or late-night meals. The combination can trigger cravings for calorie-dense foods, further raising triglyceride levels. Michelle Routhenstein, a registered dietitian specializing in diabetes education, adds that alcohol can stimulate the liver to produce more very-low-density lipoprotein (VLDL) particles, which carry triglycerides through the bloodstream. At the same time, it may reduce the activity of enzymes responsible for clearing these particles from circulation. This dual impact means that regular weekend drinking, especially in excess, can have long-term consequences for cardiovascular health. Another frequent weekend behavior that affects triglycerides is mindless snacking. Foods high in refined sugars and unhealthy fats, such as chips, candy, and fried items, are often consumed without conscious thought. These choices can cause the body to store excess calories as triglycerides, particularly when physical activity is minimal. Sealove warns that even small amounts of such food can accumulate over time, contributing to higher triglyceride levels. He recommends healthier alternatives, such as unsalted nuts, roasted vegetables, or edamame, which provide nutrients without adding unnecessary fats. Sleeping in late on weekends may seem like a welcome break, but it can disrupt the body’s circadian rhythm. Routhenstein notes that irregular sleep patterns can interfere with the regulation of glucose and fat metabolism. Consistently going to bed later than usual or waking up at different times can throw off internal clocks, leading to metabolic changes that favor fat storage. For those who struggle with insufficient sleep during the week, the temptation to catch up on rest may come at a cost to overall health. Experts advise maintaining consistent sleep schedules throughout the week to support stable metabolic function. Similarly, limiting alcohol intake and making mindful food choices during leisure hours can help prevent unnecessary spikes in triglycerides. By recognizing how everyday habits influence health markers, individuals can take proactive steps toward better wellness.
