BOTTOM LINE: The coffee diet highlights coffee alongside whole food while limiting processed foods and calories. Although it may help weight loss, there is a high danger that you will regain weight. In addition, its elevated quantities of caffeine may have side effects.
What is the coffee diet?
Dr. Bob Arnot’s book “The Coffee Lover’s Diet” popularized the coffee diet. Dr. Arnot argues in the book that drinking coffee several times a day can increase your metabolism, burn more fat, block the absorption of calories, and lower your appetite.
He was motivated to write the book after researching the individuals residing on Ikaria, a tiny Greek island with a big population of healthy seniors. He thinks that their health and longevity are the consequence of their elevated consumption of coffee rich in antioxidants.
How it works
The coffee diet plan includes drinking light-roast coffee at least 3 cups (720 ml) per day. Light roasts tend to be richer in polyphenol antioxidants than darker roasts
Dr. Arnot emphasizes the sort of coffee you choose and how it is brewed. He proposes that you grind a lightly roasted, whole-bean coffee at home and prepare it with filtered water.
On the diet, as long as you achieve your 3-cup (720-ml) minimum, you can have as much coffee as you want — caffeinated or decaffeinated. You should, however, avoid using sugar or cream.
He also advises replacing one meal a day with a homemade green smoothie, high-fiber. The book contains suggested smoothie recipes.
Your other meals and snacks of whole grains, fruits and vegetables should be small in calories and fat and rich in fiber. The author also promotes readers to prevent extremely processed foods in favor of whole foods, such as frozen foods and refined snack foods.

In the book, the sample meal plans of Dr. Arnot contain about 1,500 calories per day, which is likely to be much less calories than consumed by a typical person. Tofu and vegetable stir-fry over brown rice, or a grilled chicken salad with a vinaigrette dressing, would be appropriate meals for this diet.
Some individuals reported success in weight loss with this diet, probably owing to the implied calorie restriction. Furthermore, there is some proof that coffee can help weight loss.
SUMMARY: Dr. Bob Arnot, who argues that coffee can help you lose weight, created the coffee diet. You drink at least 3 cups (720 ml) of coffee a day on this scheme, replace one meal with a green smoothie, and concentrate on low-fat, high-fiber meals and snacks.
Potential benefits
Coffee is rich in caffeine and polyphenols called antioxidants, which have several health advantages, including reduced inflammation and free radical damage. Coffee seems to have two potential advantages when it comes to boosting weight loss — reducing appetite and growing metabolism.
Dr. Arnot claims that coffee can suppress your appetite and help you reduce your daily consumption of calories. Some study suggests that to some extent this is true. Before a meal, drinking coffee can reduce how much you eat at that meal.
However, consuming 3–4.5 hours of coffee before eating does not seem to affect how much you eat at the next meal.
A research conducted in 33 individuals who were either overweight or normal weight discovered that drinking coffee reduced calorie consumption in overweight individuals.
Each individual got breakfast over 3 sessions in the research and either water, regular coffee or half caffeine coffee. There was 2.7 mg of caffeine per pound (6 mg / kg) of body weight in the regular coffee.
When those who were overweight drank 6 ounces (200 ml) of coffee afterwards, they consumed much less calories compared to half of the caffeine when they drank water or coffee.
In contrast, one research in 12 individuals discovered that there were no variations in calorie consumption or appetite between those who drank caffeinated coffee, decaffeinated coffee, or placebo before a meal.
Caffeinated coffee may assist to lower some people’s calorie consumption, but more study is required before definitive claims can be made.

May increase metabolism
In specific, coffee may boost the quantity of calories and fat you are burning, making it simpler to lose weight.
Researchers discovered that higher consumption of caffeine was associated with reduced weight, body mass index (BMI), and fat mass in one study involving more than 600 individuals.
When the consumption of caffeine by respondents doubled, their weight, BMI, and fat mass reduced by 17–28%.
A supplement containing caffeine and polyphenols— two significant active parts of coffee— or a placebo was taken by 12 adults in another research. The supplement led respondents to burn substantially more fat and calories than the placebo.
Coffee can also increase the quantity of fat that you burn when you work out.
One research examined the impacts of coffee in seven healthy males who worked 30 minutes, then consumed about 1 cup (250 ml) of either water or coffee. Those who drank the coffee were burning more fat than those who drank water.
Much of the coffee and metabolism studies was performed in the 1980s and 1990s, however. Recent study would assist reinforce these results. In addition, there is little latest proof to support some of the stronger suggestions of Dr. Arnot.
SUMMARY: Research shows that coffee can help weight loss by reducing your appetite and calorie consumption while reducing the amount of calories you are burning. However, to fully comprehend how coffee impacts weight control, more study is required.
Downsides
Coffee includes good antioxidants and by suppressing your appetite and improving your metabolism can help you lose weight. However, there are several downsides to the coffee diet.
Excessive caffeine
While decaffeinated coffee is a coffee diet alternative, most individuals prefer caffeinated coffee. In addition, caffeine is ascribed to many of the metabolic advantages of coffee.
In over 1,100 individuals with high blood pressure, an observational study examined the connection between coffee and blood pressure.
Those who consumed three or more cups of coffee a day had greater measurements of blood pressure than those who did not drink coffee.
Caffeine is also a diuretic, which means that more fluid is excreted through the urine. If you’re drinking a lot of coffee, you might need to use the toilet more often.
In addition, many significant electrolytes, including potassium, can be lost with fluid. Losing too much potassium can lead to a disease called hypokalemia that can influence your heart and muscle control.
Coffee-induced hypokalemia, however, is rare.
Finally, excessive intake of caffeine was associated with heart attacks, headaches, insomnia, and increased risk of bone fractures, osteoporosis, and even depression.
Although it can be dangerous to drink excessive quantities of caffeinated coffee, caffeine intake of up to 400 mg per day or about 4 cups (960 ml) of coffee is usually regarded safe.

According to some research, about 80% of people who lose weight on a low-calorie diet regain some weight in their first month off the diet. Within 5 years of stopping their diet, nearly 100% of individuals regain all their lost weight.
