Why high cholesterol persists despite low carb intake

I've reduced my carb intake, barely eating rice, but my weight is still increasing, and I even have high cholesterol. Can you explain this? (Hong, 35, Hanoi)

Answer:

Many people experience high cholesterol, and even obesity, despite a low-carb diet, often due to unhealthy eating habits. Obesity is a primary cause of high cholesterol. Being overweight triggers the body to produce more triglycerides and low-density lipoprotein (LDL), or "bad" cholesterol, while decreasing high-density lipoprotein (HDL), the "good" cholesterol. Furthermore, obesity causes insulin resistance, prompting the liver and fat cells to release more fat into the bloodstream, exacerbating the condition.

Many individuals who cut down on carbs also lack physical activity. This prevents their bodies from effectively burning energy, leading to weight gain. Additionally, eliminating carbs without replacing them with essential nutrients can cause nutritional imbalances. For example, consuming excessive amounts of sugary foods, fats, red meat, or organ meats while lacking vitamins and minerals can lead to constant hunger and cravings. As a result, these unnecessary substances are converted into stored fat.

Unscientific carb reduction can also disrupt metabolism, hindering calorie and fat burning. Excessive calorie restriction can even cause hormonal imbalances, leading to cholesterol disorders even in thin individuals.

Instead of eliminating carbs, focus on healthy eating habits to manage weight and cholesterol. Eat regular meals within an 8- to 12-hour window each day. Crucially, maintain a balanced diet incorporating the 4 essential food groups: carbohydrates, protein, fats, vitamins, and minerals. Eat slowly, chew thoroughly, prolong meals beyond 25 minutes, and eat until only 80% full to allow the body to process food efficiently.
