I never skip breakfast. I mean never in 65 years of life. I enjoy having breakfast, stay full, and lose weight well. My husband doesn't generally eat breakfast till he's awake for several hours. He never loses weight. I don't know if the two are connected or not.

I seldom eat a morning meal. Heck, I'm seldom up and out of bed before 10 - 11 in the morning and typically the only thing I'll have is a cup of coffee and water. On rare occasions I'll make breakfast but it's only once in a blue moon.

I mainly listen to my body and it generally tells me when I need to eat, but the meds I take do mess with my appetite a bit and sometimes I have to remind myself that I haven't eaten all day.

I am still loosing weight but slowed it down after the first of the year via a bump in calories. As for mood and energy I'm probably not the best person to answer those as a chronic pain and fatigue person though I am more clear headed than I've been in a long time so that's something.

I eat breakfast that consists of two eggs cooked however I prefer that day and either sausage, bacon, or ham. This breakfast is filling for me and I normally don even think about food until supper time

The brainwashing of having to eat three balanced meals every day is a myth! Learn the hunger signals it’s giving you! You will find what works for you too!

I have made various changes in the way I eat since starting keto in 2016. Currently I eat a good breakfast and try to get 50 g of protein with it or I get really hungry in the late morning and will get into the cheese that was supposed to be part of lunch just to hold me over. My practice now is to eat some leftover protein from supper the night before when I wake up and have my coffee with HWC. I count this as part of breakfast, which is usually bacon and eggs. This morning I had just shy of 6 oz. of roast turkey breast from last night's supper.

Before I figured out the protein thing for me, I sometimes kept peanuts and would eat an ounce of them at 10:30 or so.

As a data point that is significant to my situation, I am T2D. I am off meds and manage the BG with the keto diet. In general the hunger is well controlled, but I find that unless I keep protein higher than most, I will be hungry at 10:30 and 4. I sometimes have a tin of sardines as a snack at 4. If protein was good at lunch, I am fine until supper.

It's not actually skipping breakfast doing IF because if you break down the word BREAK - fast it implies a break in the fast. With IF the fast is longer than a typical 12 (?) window of not eating which is largely during sleep. Doing IF is eating breakfast later in the day, that's all. It`s just an extended fast rather than a typical fast

In terms of fitness and health, meal timing is mostly irrelevant. Even for olympic level athletes the improvements to performance are statistically insignificant (less than 3%). What you eat, how much you eat, these are key, when you eat, it doesn't matter much.

There have been some studies with T2Diabetics that indicate skipping dinner is quite beneficial for blood glucose control, but that's a specific metabolic condition.

That being said, there are a lot of people who find it easier to control how much they eat by skipping meals - one less meal means you can eat more at the other two and still stay in a calorie deficit.

Some people find that skipping meals makes them more likely to eat whatever they can grab quick and then they make poor food choices, so starting out, you may want to plan to have food that meets your goals readily available.

It really comes down to, what is more sustainable for you, what fits your life, what meets your goals and is not so cumbersome that you will want to quit. Does it make it easier or harder for you?
