Does caffeine affect weight loss? Professors provide scientific evidence to reveal what is the relationship between drinking coffee and obesity

Reader Yu-Shih used the website’s “Contact Me” on April 7, 2024 to inquire:

Want to ask if caffeine will affect the reduction of weight? Cofit has a face-push ad that reads: "I didn't know before that caffeine will affect weight loss" and pointed out that the hormone analysis was caused by caffeine. Is this true? The link above opens the post published by "Cofit My Specialty Nutritionist" on April 3, 2024. I copied its focus as follows (red words):

Enter: Thin SWEET, enjoy the first experience 350 yuan (original price 2,000 yuan)

Before, I was so energetic that I would be extremely poor and want to sleep if I didn’t drink coffee for a day, but the nutritionist said that excessive caffeine would affect hormones and reduce weight. I really wouldn't know about this without hormone quality analysis and nutritionist analysis. Because I adjusted my diet, I didn’t touch coffee for two months. I was very energetic. Not only did my body become healthy, but my skin and my temperament obviously improved. The point is that I dropped from 53 to 46, and I was almost back to my pre-pregnancy figure!

I used coffee and weight loss to search in the public medical library PubMed, and found the following articles:

2016: Caffeine intake is related to successful weight loss maintenance

2019: Caffeine exposure induces browning features in adipose tissue in vitro and in vivo. Brown fat tissue (BAT) can quickly generate heat and support large amounts of nutrients, such as glucose and lipids, …… These results show that caffeine can promote BAT function under hot neutral conditions and may have potential for adult treatment.

2019: Coffee Intake and Obesity: A Meta-Analysis. We conducted a scallion analysis through compiled data from 12 epidemiological studies identified by PubMed and Embase as of February 2019. Our combined analysis shows that higher coffee intake may be related to reducing obesity.

2019: The effects of caffeine intake on weight loss: a systematic review and dos-response meta-analysis of randomized controlled trials. The systematic review and consolidation of this random-control trial was designed to summarize the impact of caffeine extraction on fat loss. As of November 2017, we searched the following databases: MEDLINE, EMBASE, Web of Science, and Cochrane Central Register of Controlled Trials. …13 random control trials were included in the scallion analysis, involving 606 participants. Overall, this saccharide analysis shows that caffeine extraction may contribute to reduced weight, weight index and fat.

2020: The effect of coffee consumption on insulin sensitivity and other biological risk factors for type 2 diabetes: a randomized placebo-controlled trial. We conducted a 24-week random consolation control trial of 126 overweight, non-infarcine-sensitive Chinese, Malaysian and Asian Indian men and women aged 35-69. Participants were randomly assigned to drink 4 cups of instant plain coffee (n = 62) or 4 cups of coffee-like sommelier drinks (n = 64) per day. Conclusion: Drinking 4 cups of caffeine-containing coffee per day for 24 weeks has no significant impact on insulin sensitivity or insulin resistance, but is related to reduced fat mass lightness.

2023: Effect of Coffee and Tea Consumption on Adolescent Weight Control: An Interventional Pilot Study. The final analysis included 48 teenagers (11-14 years old): 18 coffee groups, 17 green tea groups, and 13 comfort agent groups. Conclusion: Coffee intake and tea syringe (to a lesser extent) may be related to weight reduction and obesity in adolescents.

So, don't say it's spending 2,000 yuan, or 350 yuan for the first time experience, but it's definitely a 2,000 yuan. Do you really dare to risk asking the Cofit nutritionist to reduce weight?

Recent notes: Reader Elliot's comment: The hormone analysis mentioned by

, based on the six major obesity types that Song ◯◯ were doing: P type, L type, C type, T type, E type, and A type, using a so-called TG3D human body scanner (applied to fashion industry measurement clothing layout and size) and question papers. It is recommended to use it for sale and use it. Home health food (what to supplement) and formulating the so-called personalized diet plan (what to limit), treating "invisible fat" that cannot be seen in the heat deficit. Such hormone analysis is roughly similar to the astrology of the constellation, fortune-telling, and energy-based energy to tell you what you can eat and what you can’t eat, and what you can’t eat, and different actors. The consultation of 350 yuan and 2,000 yuan is just a gateway that leads customers to the door, and it is still a small amount. After falling into that set of ecstasy soup, the main business is to continue online physical management plans, customized health food subscriptions, and even unintentional advanced testing and door clinics.

Note: Functional non-medical theory is the same template, and caffeine affects cortisol levels and glucose, therefore, blah blah blah……

Reader Kuan left a message: I admire those who can find these 543 fat loss methods and strange terms……. I picked up my exercise habits and started eating control two years ago, and only controlled the principle of the hot deficit, reducing it by nearly 40 kilograms. The point is that I drink 1 liter of black coffee every day.
