coffee and lemon for weight lossWhile coffee and lemon for weight loss have been a big hit for a couple of months, not many people know how to use the combo and what exactly to expect.

In this article, I will share the coffee and lemon recipe for weight loss, and some of the side effects the ladies I have spoken with have experienced. I will also answer all your burning questions like when and how many times per day should you take the combo, why you might be having sleepless nights after drinking coffee and lemon, is it safe to drink while breastfeeding, and what you should use instead if you do not like coffee.

How does coffee and lemon for weight loss work?

The big question everybody is asking is does coffee and lemon help you lose weight? Well, the science behind drinking coffee for weight loss is that overweight individuals who drink 4 cups of coffee a day may benefit from weight loss and other health benefits.

This is according to a study carried out by Harvard T.H. Chan School of Public Health researchers. The research concluded that caffeine played a significant role in boosting metabolism, which effectively increases the rate at which you burn calories.

Another study published in The Journal of Nutrition found that those who drink two or three cups of coffee a day have a 2.8% lower total body and abdominal fat than those who drink less (1). Researchers suggested that incorporating coffee into a healthy diet could reduce chronic conditions caused by obesity.

If you look at most fat burners on the market, you will notice that most of them have a very high amount of caffeine per capsule (mostly around 200-270mg of caffeine, sometimes more!).

The side effects of most fat burners should be the reason why you should be brewing your cup of coffee and lemon for weight loss. 

On the other hand, apart from being a great source of vitamin C, drinking lemon water has loads of health benefits. Lemon contains antioxidants that help in boosting the immune system. Other notable benefits of lemon include the prevention of kidney stones and improved digestion.

On the weight loss front, lemon contains micronutrients called polyphenols, which have been proven to suppress body fat accumulation and weight gain (2). In a study carried out in Japan by a team of researchers, it was found that lemon also significantly helps in regulating levels of insulin and glucose and may prevent obesity.

Frequently asked questions about coffee and lemon juice for weight loss

The information shared here was part of research that I carried out in various Facebook groups from real people who have tried this diet. Some were successful with losing weight, while others had their own up and down experiences. All in all, this answers the most frequently asked questions in the dedicated coffee and lemon FB groups. As you jump on the lemon and coffee drink wagon, the answers below will help manage your expectations.

How many times per day should you take the lemon and coffee combo?

Rule number one of anything good in life is that you must do it in moderation because sometimes the line between good and bad tends to be thin. In the case of this weight loss drink, the line becomes very thin pretty fast. Stick to a maximum of 4 cups per day of the lemon and coffee drink for weight loss. Anything over that may result in side effects- I will discuss this further down.

For example, you can have coffee and lemon in the morning but if your body can not handle too much caffeine, your second drink just before bed should only be a cup of lemon and warm water.

Can I drink coffee and lemon for weight loss while breastfeeding?

The simple answer is no! You should NOT drink coffee and lemon for weight loss while breastfeeding because whatever you eat or drink is passed on to the baby. As you may already know, caffeine is bad for the growth and development of the baby plus, the combination of lemon and coffee decreases milk supply. As a nursing mother, your focus should be on ensuring that your baby gets all the nutrients through breast milk.

The best way to lose weight while breastfeeding is through exercising, controlling your meal portions, and eating healthy consistently.

How long should you wait to eat other foods after drinking coffee and lemon?

When you wake up in the morning, prepare and take your coffee and lemon and then wait 30 minutes before you can have breakfast. If you are also taking the combo in the evening, then have the drink 30 minutes after your last meal for the day.

Which brand of coffee is best for weight loss?

Any brand of coffee with a reasonable amount of caffeine will work. Decaf coffee will not work well because you need caffeine to speed up your metabolism and suppress appetite.

Can I add sugar or honey to my lemon and coffee weight loss drink?

No! You cannot add sugar, honey, or artificial sweeteners to your lemon and coffee weight loss drink. Sugar has no nutritional value, apart from the empty calories you will get from it.

Refined sugar falls under simple carbs- which are broken down quickly by the body. Simple carbs will give you the energy that will only last for a while before sending you into an energy slump.

What should I eat when drinking coffee and lemon for weight loss?

I always preach on eating healthy for life and not cutting out food groups. Each food group provides essential nutrients, and eliminating foods like fats, dairy or carbohydrates deprives the body of crucial nutrients.

Yes, you must avoid processed foods such as chocolates, sweets, fizzy drinks, cold meat, pastries, white bread, and cakes but everything else that is healthy, you should eat in moderation.

Your plate should ideally consist of lots of vegetables, some protein, a few complex carbs (sweet potatoes, quinoa, brown rice, beans, etc.), and healthy fats. You should also drink about 10 cups of water daily and be active by walking more.

Coffee and lemon for weight loss side effects

Not everyone experiences side effects when taking the lemon and coffee combo. Some people experience nausea, while others have had tummy cramps, runny stomachs, and heartburn. If you experience anything severe, stop immediately, and always remember social media is not a hospital.

You need to consult a doctor before starting a new diet if you have pre-existing conditions or are overweight.


Some ladies that have tried this combo have reported headaches. Caffeine can cause headaches, and if you are not used to it, you might experience headaches during the first few days. Start with only one cup of coffee a day and see how your body reacts.

If coffee is not your thing, try substituting it with green tea. You could also just drink warm lemon water. Another weight loss drink that has no caffeine but is effective is this lemon, mint, and ginger weight loss drink.

Coffee and lemon for weight loss results

This coffee and lemon for weight loss review is between 15  December 2021 and 16 February 2022, which is about 2 months. I did not change my diet much since we were in the middle of Christmas and New Year festivities. I ate pretty much everything, especially during the week leading to Christmas. 

I also did not do a lot of exercises during this period apart from walking 3 times a week. The starting weight was  242 pounds (110 kg) and was down to 224 pounds (102kg) in February. 

I honestly feel I lost more inches than pounds looking at the side-by-side photos. I did not experience side effects mostly because I am used to drinking coffee.

Final thoughts on coffee and lemon for weight loss

Fad diets have come and gone, and this might or might not be a fad.

What remains the same is the desire to want to lose weight. Weight loss is a long game, and if you are trying to lose weight because you need to look good for an occasion, you will probably lose the weight and gain it all back after the special event. Take your time, make sure you have a plan to maintain your weight loss, and if you have tried everything to lose weight but in vain, then maybe it is time to work with a dietician.

While this combo seems to work wonders for most people, it might not work just as well for you because everyone is different.

  1. Not one article states if the “coffee” is brewed, instant, or coffee powder!
    The more I read I’m more or less heading towards brewed coffee, but I’d like to know for sure.
