No it's deception not lying.
There are many methods of deception, lying being the most prominent.
Lying is bad because it's a form of deception.
You can of course deceive someone into thinking the opposite of what's true using entirely truthful statements, that doesn't make it any better.

Sissela Bok spends half a book on this. And her ultimate approach is not to answer the question, but to consider the motive involved. If your motive is to deprive others of power they should have, you are lying, whether explicitly or by omission.

But that consideration opens onto another range of questions: At what point do people deserve to have power? You may not tell your neighbors where you keep your extra keys, because it is perfectly legitimate to limit their power to investigate your home...

Lying is a communication intended to deceive or mislead. Lies of omission, and of misdirection, are lies.

One effort to limit the extent of "lying" is to try to distinguish between overt and implicit deceptive language. The assumption here is that the actual words are what constitute lying, and the effort to mislead through innuendo, skewed facts, or changing emphasis on workds or syllables -- is somehow NOT linguistic communication. But linguistic communication, of course includes both overt words and innuendo, and both syllabic and word emphases.

Communication is also often non-linguistic. Pointing to oneself, if a party is asked to identify themselves -- if one is not the party requested, is deliberate deceptive miscommunication. Whenever one knows that others are reading one's signals, then misleading them by sending out false signals is a deliberate effort to mislead.

It is not just humans who lie. I had a dog, who after being fed by my wife, would often come up to me and look mournful and hungry -- trying by misdirection to get double dinner. Both predator and prey animals will make feints in one direction or another, to mislead their adversary.

The best analysis of lying I have seen was from libertarian thought, and it treated lying as a degradation of the common currency of communication we all need to access the world and society, hence all miscommunication of any kind was harmful to all. This is treating humans as a primarily social animal, who rely upon the marketpalce of ideas to be functional to gain reasonable information -- and subversions of that marketplace serve as a parasitic behavior that degrades its value to all.

The answer depends greatly on who you ask, and whether they benefit from you being labeled as a "liar."

There are some who will call it a "lie of omission." That phrase is indeed popular.

However, there clearly must be some other side to it, because merely labeling "hiding a truth" as "lying" labels a great many things that we typically don't think of lying. For example, if you ask me for my online banking password, and I refuse to tell you, is that lying? If a teacher knows the answer to a question on a test, and a student asks them for that answer, is it lying for the teacher to refuse? Is a soldier entrusted with national secrets lying when they refuse to hand them over?

These cases suggest that if there is indeed something to be called a "lie of omission," it must be nuanced enough to sidestep them.

I'd disagree. In my opinion, a statement must be intentionally false to be a lie. That said, it's not ethical to deceive people by withholding information like this, and I'd consider it dishonest, but not lying. Also consider that you cannot be sued in the US for defamation as long as what you alleged was true. https://www.nolo.com/legal-encyclopedia/libel-vs-slander-different-types-defamation.html states that "Truth is an absolute defense to Libel and Slander". In other words, in the eyes of the law, it's not lying if it's true.

From "The Gulag Archipelago" by Aleksandr Solzhenitsyn, part 1 chapter 3 "The Interrogation" (bracketed clarifications added):

N. Stolyarova recalls an old woman who was her neighbor on the Butyrki bunks [in lockup] in 1937. They kept on interrogating her every night. Two years earlier, a former Metropolitan of the Orthodox Church, [equiv to a bishop or perhaps archbishop] who had escaped from exile, had spent a night at her home on his way through Moscow.

LADY: "But he wasn't the former Metropolitan, he was the Metropolitan! Truly I was worthy of receiving him."

INTERROGATOR: "All right then. To whom did he go when he left Moscow?"

LADY: "I know, but I won't tell you!"

Did the old lady lie to the interrogators? Was she morally obligated to answer their question as it was stated? I believe that the answer to both questions is "no".

"The beginning of wisdom is the definition of terms." In this case, it entirely depends upon your definition of lying. If lying requires an explicit statement to be spoken which one knows to be false, as in Google's "an intentionally false statement" definition, it was not a lie. If lying instead includes the intent to decieve, as in Dcleve's definition, then it was a lie.

Hence, if the concept of 'lying' specifically is important in your ethics, you need to decide upon its definition to then discern how ethical an action is.

What may be more sensible is adjusting your ethics to instead concern itself with 'deception', which may even be your intended meaning and is a more clear-cut term.

It's quite complex philosophically, what constitutes a lie. A person can make a statement to gain personal advantage, believing it to be untrue, and yet still be literally telling the truth, because there is an error in their understanding of the world. Are they lying? Most people would say yes in that context, because they believe they are lying, even if they are giving accurate information.

This means that intention says a lot.

In your case, your intention was to mislead. Many people would argue that you didn't lie, others would say that you did in some fashion. But clearly you intended to mislead. You are manipulating the listener's understanding of the world to suit your agenda. It's clearly (at least) very similar to lying.

In this case the person who was supposed to speak the truth were you. Your wife was not asking what you were doing then. So, what you should do was to inform her the two main activities you did. Here your activities were transformed into spoken form. So, all the words you used and the tone/voice modulation had great importance. But you deliberately hid a part of the truth. There was no chance of filling up of your eating sweets. If there was, and you didn't feel ANY guilty of telling so, you could say that you were speaking the truth. Otherwise you were lying. If you are deliberately leaving some ambiguity in your reply, it can be treated as a partial truth or partial lie. (In your reply you didn't leave any ambiguity. So it cannot be treated as a partial lie.)

You might argue: "In future, scientists might discover that 'consumption of sweets doesn't have any relation to diabetes', would it be a lie then?" Yes. Since your intention was not to speak the truth (you were hiding an important thing of that time), even in such a situation your reply is/would be a lie.

DECEPTION Vs LYING

The meanings given for the word 'Lie' (Noun/verb ) in some dictionaries:

Noun:

1. A lie is something that someone says or writes which they know is untrue.




2. An intentionally false statement.

Verb:

1. to deliberately tell someone something that is not true




2. to say or write something that is not true in order to deceive someone

Meanings of 'Deception':

1. the act of hiding the truth, especially to get an advantage




2. a statement or action that hides the truth, or the act of hiding the truth

Both in deceiving and in lying, hiding of truth happens and the liar (deceiver) gets some advantage also.

When we omit some words in a sentence sometimes they become false statements. (What happens if you omit the word 'not' in this sentence: 'All that glitters is not gold.')

Just remember how a child complains to their teachers or parents after quarreling with another one. Does the liar tell all the things he did? Truth often comes out only after questioning. So the statements that mislead someone are lies. The same thing is done in courts.

Lies mislead the sufferer (or the listener) and most often it becomes a deception if viewed from the sufferer's side. Even if the listener is not there to hear the lie, lie has been told (even in the absence of deception). That was another reason for treating your statement as a lie (rather than a deception).

To make it clear,

Suppose, a third party is listening to your conversation. Then, your lying wouldn't be a deception to your wife if she is not (at the other end) to listen to your reply. Even from the third party's point of view there is no deception in such a situation. In your particular case, you deceived your wife by telling a lie. Lie came out first and it affected her as a deception. You may say that your lying is the cause of deception. But you can never say: "Deception is the cause of your lying."

Please note: Telling a lie may be a part of practicing Dharma. I mean, if you lied and if you were asked ("Were you lying to him?"), without any hesitation you could say that you were lying. So, if no other alternative is available, in order to protect a greater Dharma, you may deviate from the maxim-- 'Speak the truth always, even if it leads to your death.' (You may refer the Mahabharata.). So you need not reveal all the secrets to all.

Since so many viewers are interested in this question, I believe this doubt also is latent in your question.

That depends on how technical you want to get.

If you were at the ATM when you said 'I am withdrawing money', then technically, it was not a lie. But if you were at the shop and said that, then yes it is a lie.

But, as you said, your primary intention was to eat sweets, holistically, your actions fit with Google's definition of lying ("An intentionally false statement").

As said previously, a lie of omission is still a lie.

Lying and hiding a truth are different things, but they may have the same intention.

Lying is saying wrong information when you know it is wrong. The intention is to make a person think and behave in some specific manner.

I can't tell what hiding a truth is. But the intention is the same: to make a person think and behave in some specific manner.

They are different but may be considered to be ethically equivalent because they both cause the same consequences. But I guess lying is usually considered to be more unethical. It's probably because lying is active tactics, and hiding a truth is passive tactics. But anyway it is subjective.

Whether or not that being silent on or not including information constitutes lying (deceitfulness) or not depends upon the expectations of the other party to which information is being given or withheld and also how that party is or can be reasonably expected to interpret the information with which sie is going to be furnished or not furnished.

Deception, after all, means to purposefully communicate to someone something with the intention of causing to arise in them a belief in the truthfulness or reality of that which is not true or not real. In particular, if there is an expectation that the information that is given is to be taken as representing all details (at least to some level of specificity, e.g. typically not "I had 3 buttons on the shirt I was wearing that day") of what occurred in the situation, then to omit details communicates the message that they did not exist. If, in fact, they did, and you know this and omit these details purposefully to create a picture in their mind where they are not present, then you are causing to be communicated to them such a false picture and thus are committing deception.

And that's what I'd think happened in this case - though there seems like there might be a bit of wiggle room given how you've phrased it (which is exactly the kind of thing lawyers love, and why Maths, English and Philosophy all would make great Pre-Law undergrad degrees, I'd think) in that you've said "asked me what I am doing outside", which could be interpreted as "what are you doing outside at this present moment" - in which case actually you communicated the truth acceptably since there is no expectation then to be informed of any other details, or it could be interpreted as "what compelled you to go outside", in which case you are then omitting relevant facts to create a false perception of your motives and thus deception in accord with the previous understanding.
