SUMMARY:

 The Coffee Diet emphasizes coffee as well as whole foods while limiting processed foods and calories. Although it can help you lose weight, you are at a higher risk of recovering from it. Also, high doses of caffeine can cause side effects.

What is the coffee diet?

The coffee diet became popular with Dr. Bob Arnott's book "The Coffee Lovers Diet".

In the book, Dr. Arnott says that drinking coffee more than once a day can boost your metabolism, burn more fat, prevent the absorption of calories, and reduce your appetite.

He was inspired to write the book after studying people living on the Greek island of Icarus, which has a number of healthy older people.

He believes that his health and longevity are the result of high levels of coffee rich in antioxidants.

How it works

The Coffee Diet Plan involves drinking at least 3 cups (720 ml) of light roasted coffee per day. Light roasts are higher in polyphenol antioxidants than dark roasts.

Dr. Arnot notes the importance of coffee of your choice and how it is prepared. He recommends light fried coffee beans that are made with clay and filtered water at home.

In the diet, you can have as much coffee, caffeinated or decaf as you can until you reach a minimum of 3 cups (720 ml). However you should avoid using sugar or cream.

He recommends that you replace one meal a day with a high-fiber homemade green smoothie. Suggested smoothie recipes are provided in the book.

Other foods and snacks should be low in calories and fat and high in fiber from whole grains, fruits and vegetables. The author encourages avoiding high-processed foods such as frozen foods and refined snacks in favor of whole foods.

The book contains about 1,500 calories per day in Dr. Arnot's sample meal plan, which is probably fewer calories than the average consumer.

Suitable foods for this diet will include tofu and succulent vegetables, or a grilled chicken salad with vinaigrette dressing rather than brown rice.

Some people report success in weight loss on this diet, probably due to the calorie limitations involved. Also, there is some evidence that coffee can help you lose weight.

SUMMARY:

The coffee diet was developed by Dr. Bob Arnott, who claims that coffee can help you lose weight. In this plan you drink at least 3 cups (720 ml) of coffee per day, replace a meal with a green smoothie and concentrate on low-fat, high-fiber foods and snacks.

Potential Benefits

Coffee is rich in antioxidants called caffeine and polyphenols, which have a number of health benefits, including reducing inflammation and free radical damage.

In terms of weight loss, coffee appears to have two potential benefits: loss of appetite and increased metabolism.

Appetite may be reduced

Dr. Arnott emphatically states that coffee can suppress your appetite, helping to reduce your daily caloric intake.

Some research indicates that this is true to some degree. Drinking coffee shortly before eating can reduce the amount of food you eat.

However, drinking coffee 3-4.5 hours before meals does not seem to affect how much you eat at the next meal.

A study of 33 people who were overweight or normal weight found that those who drank coffee weighed less than those who consumed calories.

In three survey sessions, each person received breakfast and water, regular or medium caffeinated coffee. Regular coffee per pound of body weight (mg mg / kg) 2. Contains milligrams of caffeine.

Those who were overweight drank 6 ounces (200 ml) of coffee and then consumed relatively few calories compared to water or coffee with half the caffeine.

In contrast, a study of 12 people found that those who drank caffeinated coffee, decaf coffee or a placebo drink before meals made no difference in calorie intake or appetite.

Caffeinated coffee can help reduce calorie intake in some people, but more research is needed before making specific claims.

May increase metabolism

Caffeinated coffee, in particular, can increase the number of calories and the amount of fat you burn, making it easier to lose weight.

In a review involving more than 60,000 people, researchers found that high caffeine intake was associated with weight loss, body mass index (BMI), and fat mass.

When the participants' caffeine intake doubled, their weight, BMI, and fat mass decreased by 1-2%.

In another study, 12 adults took a supplement containing caffeine and polyphenols, the two main active ingredients in coffee, or a placebo. The supplement forced the participants to burn significantly more fat and calories than the placebo.

Working with coffee can increase the amount of fat you burn.

One study looked at the effects of coffee in healthy men who exercised for 30 minutes and then drank about 1 cup (250 ml) of caffeinated coffee or water. Those who drank coffee burned more fat than those who drank water.

However, most of the research on coffee and metabolism took place in the 1980s and 1990s. The most recent research will help strengthen these searches. Also, Dr. There is no recent evidence to back up Arnott's strong claims.

SUMMARY:

Research indicates that coffee can help you lose weight by reducing your appetite and calorie intake, while increasing the number of calories you burn. However, more research is needed to fully understand how coffee affects weight management.

Disadvantages

Coffee contains healthy antioxidants and can help you lose weight by suppressing your appetite and stimulating your metabolism. However, there are several downsides to the coffee diet.

Excess caffeine

Although defined coffee is an alternative to the coffee diet, most people prefer caffeinated coffee. Also, caffeine is blamed for many of the metabolic benefits of coffee.

However, excessive caffeine intake can lead to a number of health problems, such as high blood pressure.

An observational study found a link between coffee and blood pressure in more than 11,000 people with high blood pressure.

Those who drank three or more cups of coffee a day had higher blood pressure levels than those who did not.

Caffeine is also a diuretic, which means that it causes you to excrete more fluid through your urine. If you drink a lot of coffee, you should use the bathroom frequently.

Also, fluids with potassium can lose many important electrolytes. Excessive potassium loss can lead to a condition called hypokalemia that can affect muscle control and heart health. However, coffee-induced hypokalemia is rare.

Finally, excess caffeine intake has been linked to the risk of heart attack, headaches, insomnia and bone fractures, osteoporosis and even depression.

Although drinking excessive amounts of caffeinated coffee can be harmful, taking up to 400 mg of caffeine per day or about 4 cups (960 ml) of coffee is generally considered safe.

Weight regain is likely

Diet plans that involve a drastic reduction in calorie intake, such as the recommended 1,500 calories per day in a coffee diet, can often lead to weight gain as a result of a series of changes in your body as you cut calories.

Your body consumes a regular amount of calories. Therefore, when you significantly reduce your calorie intake, your body slows down your metabolism, reducing the amount of calories you burn.

Also, the hormonal changes that occur as a result of calorie restriction can increase your appetite.

The hormone leptin that promotes the feeling of fullness and signals your brain to stop eating. However, leptin levels in your body can be significantly reduced on a low-calorie diet, which can lead to increased appetite and appetite.

For this reason, it is very difficult to lose weight on a diet that requires a significant reduction in calorie intake like the coffee diet. The end result is usually weight gain.

According to some studies, about 80% of people lose weight on a low-calorie diet and regain some weight outside of their diet in the first month. About 100% of people regain all their lost weight within 5 years of completing the diet.

Not safe in the long run

According to testimonials, people usually follow a coffee diet for two to seven weeks.

In fact, it can be dangerous in the long run for a number of reasons.

Drinking large amounts of caffeinated coffee can lead to excess caffeine intake, which can lead to various problems including insomnia and depression.

The coffee diet is also a low calorie food, which can cause problems in losing weight and keeping it away.

Unfortunately, no long-term research has evaluated the safety or effectiveness of the coffee diet.

For this reason, your coffee diet should not be followed in the long run.

SUMMARY:

There are significant reductions in the coffee diet. This can cause excess caffeine intake. Also, this type of regular diet can lead to weight gain. Currently, there is no research on the long-term safety or efficacy of diet.

It's healthy

Unfortunately, the coffee diet is not the ideal weight loss plan.

Excessive intake of caffeine may result in excessive consumption of your coffee. Also, your calorie restriction can help you regain lost weight.

Successful weight loss diets often involve only a small calorie restriction, resulting in slower and more sustainable weight loss and a reduction in the negative metabolic changes associated with calorie restriction.

Increasing your protein and fiber intake, reducing the amount of refined sugars you eat, and exercising regularly can help you lose weight and avoid it.

For most people, they can follow the most successful diet to lose weight.

SUMMARY:

Coffee diet is not the best option for healthy weight loss. Sustainable diet plans are more likely to be successful in the long run.

BOTTOM LINE:

The Coffee Diet encourages you to drink at least 3 cups (720 ml) of coffee per day while restricting your calorie intake.

While it can lead to weight loss in the short term, it is not a healthy diet in the long run.

This can lead to weight recovery and adverse effects as a result of excess caffeine intake.

You can still enjoy the health benefits of coffee but stick to the safe limit of 4 cups (960 ml) per day or less.

To lose weight safely and healthily, you should avoid preventive programs such as the Coffee Diet for a more sustainable plan.
