Coffee, as one of the most popular beverages worldwide, attracts hundreds of millions of loyal enthusiasts every day, enjoying its unique charm. Coffee not only invigorates the spirit but also offers numerous pleasures and delights. However, for certain groups of people, coffee may not be a completely healthy beverage choice and requires careful consideration of its effects.
Is the black coffee weight loss method reliable?
The basic concept behind the black coffee weight loss method is to drink unsweetened, non-dairy black coffee to aid in weight loss. Proponents believe that the caffeine in black coffee can boost metabolic rate, enhance fat oxidation, and promote weight loss. Additionally, caffeine has an appetite-suppressing effect, which can reduce calorie intake.
Scientific studies have shown that moderate caffeine can temporarily increase metabolic rate and promote fat burning. However, this effect does not last long and varies widely among individuals. Although caffeine can suppress appetite, this effect varies from person to person. For some, coffee may induce anxiety and discomfort, which can lead to emotional eating and actually increase calorie intake.
Moreover, the antioxidants in coffee are beneficial for health, helping to reduce inflammation and improve cardiovascular health. However, it is important to note that excessive caffeine intake may lead to negative effects such as anxiety, insomnia, and palpitations.
These 5 types of people should stay away from coffee.
1. People sensitive to caffeine
Caffeine is a stimulant that can increase alertness and attention, but not everyone can tolerate it well. For some, caffeine intake may lead to symptoms such as rapid heartbeat, anxiety, and insomnia. If you feel palpitations or nervous after drinking coffee, you may belong to this group. It is advisable to choose decaffeinated beverages or try other milder energizing options, such as green tea or herbal tea.
2. Pregnant and breastfeeding women
Pregnancy and the breastfeeding period are two crucial stages in a woman’s life, accompanied by profound changes in physical and physiological states, placing stricter demands on daily diet and lifestyle habits. Multiple studies have pointed out a significant association between high doses of caffeine intake and adverse pregnancy outcomes, including but not limited to increased risks of miscarriage and preterm birth, as well as potentially leading to low birth weight in newborns, all of which are directly detrimental to fetal growth and development. Additionally, caffeine may penetrate the placental barrier through the maternal circulatory system, subtly and profoundly affecting the neurodevelopment of the fetus.
