Is it normal to be tired by 2pm if you wake up at 5:45am?

My diet is pretty much the same from week to week.

Breakfast: 7am or 7:30am. Cottage cheese with a fruit such as peaches or pineapple. At 6am I always have a glass of chocolate milk before my morning walk/jog. I read that chocolate milk is the best post recovery drink. I exercise longer when I drink it as well. By the time I'm done with my jog/walk around 7am I cook my breakfast. It could be anything from veggies such as carrots with cream cheese (1 serving of each) or it could be a bowl of high fiber cereal or french toast (high in protein due to eggs) or once in a while (once a month) I'll make biscuits and gravy.

Brunch: This is 10am. Fiber 1 brownies the double chocolate or lemon or mint chocolate - doesn't matter since they are all 90 calories and 5 grams of fiber each.

Lunch: Lunch time for me is always 11am or 11:30am most days unless I'm running errands - then I must eat lunch at 10:30am and "eat rushed" which I HATE doing. Or I may have a late lunch (again if running errands) and have it around 3pm. I hate eating lunch at 3pm. I eat at least 2 or 3 BLT's a week for lunch. But I don't use real bacon, I have turkey bacon and I add in healthy fat from avocado (1/2 of avocado is all I eat since 1 full avocado is 5 servings). I add in thousand island dressing and I measure everything (I count calories).

After I'm done with lunch I have consumed around 800 - 1,000 calories.

Dinner is 5pm or 6pm and my dinner is small. Since my breakfast is anywhere from 350 calories (low side) up to 475 (the high side) I make my lunch 350 - 400 calories and my dinner is usually <<<no more than 300 calories>>>>. I like to high a higher calorie intake in the morning so I can burn it off as the day goes on.

<<<I don't eat after 7pm and I got to bed at 10pm sharp>>>>. I also don't get hungry after 7pm. I get about 20-25 grams of fiber each day. I also eat beans, but not every day. I know I'm eating right since I have gas and gas is good. It just makes people wonder what you are eating and what your problem is if you are near people. I get 7 hours of sleep each night and I wake up around 5:40am daily. I'm out of bed in 10 minutes. I have no problem getting out of bed in the mornings. I have a surge of energy in the morning. So I'm thinking due to this - it can't be a thyroid problem such as low thyroid. Usually people with hypothyroidism are very tired in the morning. I'm not. Chronic Fagtigue Syndrome also makes people tired - in the morning.

I'm obese, not overweight. A person that is 50 pounds "overweight" is medically considered obese. I don't take any medication except Singular for my sinus issues. I use Bipap everyday (My AHI is 10 without using any xpap). If you don't know what Bipap or CPAP is, it is for people with sleep apnea. I have mild sleep apnea and since using xpap in 2013 my energy has gone sky high. (I used to take naps daily, now I only take naps for 4 days before my period). I'm a female and before my period (up to 7 days before my period) I get extremely tired tired tired. I fight the urge to nap. I don't nap until 3-4 days before I start. More tired than what I am talking about in this post.

I don't eat a high sugary lunch. My lunch is usually full of protein and good fats (nuts, avocado) and seeds and grains. Sometimes I have fruit and I know fruit has natural sugar in it. I know sugar will make one tired. I take vitamin D and I do notice a slight change in energy when I do NOT forget to take it in the morning.

I just started to take Coq10 again today (after not taking it for 5 months). I read that Coq10 helps with energy. I also added in Green Tea Extract again (after not taking it for 7 months). It seems that my tiredness is random. Some days I'm really tired at 1pm. Some days I'm really tired at 3pm. Somedays it comes at 12pm. Aside from my cycle - most days I'm only tired in the afternoon and I seem to get a burst of energy between 5pm-7pm. Right now it is just after 1pm and I can tell my mental fogginess is coming in, but I don't feel tired yet.

tt is only in the afternoon and I don't understand what is making me so freaking tired in the afternoon. If I had a high sugar diet then I'd tell myself "No wonder you are so tired". I don't crash after lunch. It is more of a mental dullness after lunch and my energy is lower and slower and I don't nap after lunch. I don't know if anyone else notices it, but I notice it. Just as long as the important people in my life don't take notice.
