The Best Time to Drink Coffee for Weight Loss

It's that cool dressing season again, and everyone is thinking about how to look slimmer. Some who are a bit lazy might consider eating less to lose weight, while more diligent individuals will choose to exercise more. The fact that drinking coffee can help with weight loss has long been common knowledge, but did you know that choosing the right time to drink coffee might help you lose weight faster?

Scientific Research on Coffee and Weight Loss

As early as December 2019, a study in the Journal of Functional Foods from the University of Illinois showed that caffeine in yerba mate can weaken fat production and accumulation caused by high-fat, high-sugar diets, limiting weight gain and counteracting some negative effects of obesity.

This January 7th, a study from the Department of Physiology at the University of Granada, published in the Journal of the International Society of Sports Nutrition, showed that caffeine can enhance maximum fat oxidation rates and aerobic exercise capacity.

The World Anti-Doping Agency (WADA) banned high-concentration caffeine use between 1984 and 2004, but later allowed it after it didn't meet standards. Caffeine intake among endurance athletes has become common, but caffeine remains on WADA's 2021 watch list.

Research Methodology and Findings

Researchers recruited 15 adult men with an average age of 32 as subjects. Subjects ingested 3 mg/kg of caffeine or placebo based on body weight 30 minutes before exercise testing. Exercise sessions were conducted at 8 AM and 5 PM, with four exercise tests performed every 7 days.

The results showed that subjects who ingested caffeine had increased maximum fat oxidation rates compared to placebo, with the morning caffeine intake group showing a 10.7% increase in maximum fat oxidation rate, while the afternoon caffeine intake group showed a 29% increase. This finding indicates that ingesting caffeine 30 minutes before exercise can significantly increase fat oxidation rates during exercise, with the enhancement effect being greater in the afternoon than in the morning.

Additional Health Benefits of Coffee

Feeling excited after reading this? More and more studies show that coffee has certain health benefits for the human body. For example, this June, the journal BMC Public Health published an article about caffeine reducing the risk of chronic liver diseases. Not only that, but some studies even suggest that caffeine can help us prevent Alzheimer's disease.

This explains why coffee shops often open next to gyms, and why gyms offer coffee vouchers to members - they're both putting in extra effort to help everyone lose weight a little faster!

Important Considerations

However, I still need to remind everyone that drinking coffee without any additives is the correct choice! Occasionally, you'll see some people holding a Frappuccino with syrup while going to the gym - what's the point? Drinking an overly sweet beverage while sweating on exercise equipment, only to find that your weight hasn't changed but your wallet has become thinner. It's like shouting about wanting to lose weight while rewarding yourself with extra meals for your efforts - it's all for nothing.

Warning about drinking coffee with additives while exercising

Ladies, to be able to wear beautiful dresses outdoors sooner, let's take action! Although research results show that drinking coffee before afternoon exercise has higher fat oxidation rates, if drinking coffee in the afternoon affects your sleep at night, don't force yourself.
