Does coffee make you less hungry?

In this text, we will answer the question: “Does coffee make you less hungry?”. In addition, we will talk about the relationship between drinking coffee and being hungry. Furthermore, we will discuss if drinking coffee regularly is healthy.

Does coffee make you less hungry?

Yes, coffee can make you less hungry. In most people, caffeine even decreases appetite. However, there are people in whom caffeine, by causing more anxiety and agitation, can lead to increased hunger, or “desire to eat”.In general, coffee (and caffeine) does not stimulate appetite.

Therefore, scientifically we can say that the amount of caffeine normally consumed per day, through coffee, does not change the appetite in the short term.

Knowing that the appetite control mechanism is quite complex and encompasses several organic systems.

One of the ways described as the action of caffeine in appetite control is the increase in the production of one of the hormones responsible for inhibiting appetite when at high levels in the blood, Peptide YY (PYY). 

However, this increase is more evident in decaf coffee (without caffeine), which suggests that there are more substances capable of interfering with this metabolism.

Caffeine is also a potent stimulant of the central nervous system, which increases the body’s energy expenditure and favors fat burning, justifying its indication in weight reduction diets.

The use of caffeine in capsules with the aim of losing weight should be done under the guidance of a professional as a nutritionist, due to the risks of side effects such as tachycardia, vascular and blood pressure problems.

Does drinking coffee make you lose weight?

Yes, drinking coffee can make you lose weight by modifying the production of hormones that influence appetite and satiety. However, It also can not help you lose weight. The same will happen with humor.

There are three hormones responsible for hunger: ghrelin, leptin and peptide YY. The first is secreted in the stomach, the second is synthesized in fat cells, and the third is present in the intestine.

Have you ever noticed that when we are hungry we can get angry or very irritated and after eating, happy? Remember the popular saying: “full stomach, happy heart”.

Two hypotheses are considered to determine what the relationship between coffee and hunger/satiety is:

First hypothesis: coffee (decaffeinated or caffeine) decreases hunger, leptin and ghrelin and increases satiety and peptide YY.

Second hypothesis: the same effects as in the first hypothesis, but with the condition that they only last 60 minutes after ingestion or during the 120 minutes it takes for the body to digest.

Does caffeine speed up metabolism?

Yes, caffeine speeds up metabolism. Coffee initiates thermogenesis and can help you speed up your metabolism.  However, this effect occurs with natural, pure coffee, without milk or sweeteners. Of course, we shouldn’t drink coffee compulsively because too much caffeine can cause negative effects, such as nervousness or tremors.

Should I eat food after drinking coffee?

You shouldn’t eat food after drinking coffee. Coffee reduces the absorption of iron from some specific foods, such as beans, red meat, vegetables, and dark green leaves. It is precisely at the main meals – lunch and dinner – that these foods are more present.

So, does it mean that we have to abolish coffee after lunch forever? Not necessarily. If the person has a good diet throughout the day, with lots of vegetables, fruits and nutritionally complete, it will not be a cup of coffee that will compromise their health.

The greatest losses in nutrient absorption when consuming coffee after meals are for people who follow a vegetarian or vegan diet without nutritional monitoring and those who lack the vegetable iron present in legumes, vegetables and leafy vegetables.

In this case, the ideal would be to eat just two hours after consuming coffee and not drink it immediately after the meal.

The caution goes not only for coffee, but also for green tea, black tea and cola-based soft drinks, as these also contain a lot of caffeine.

Is drinking coffee healthy?

Drinking coffee is healthy. However, not all people metabolize it in the same way. What you need to know is that this drink modifies neurotransmitters and hormones (especially cortisol and insulin).

That’s why there are people who “wake up” and others who make them “sleep”. This can change depending on how much we drink, the time of day, age or physical build. In any case, we must always take into account the need to have good consumption habits and remember that it is not good to abuse anything.

It is worth noting that coffee has many antioxidants that are beneficial to health, but also some of its components are negative for certain people, especially if consumed in excess. If you’re relying on caffeine to suppress your appetite, you should start considering another strategy.
