Dinner time and its impact on Fasting Blood Sugar

My dinner got delayed by an hour for the last two days. Surprisingly, my FBS has come down by at least 10 to 20 points. These are my readings.

Last Friday Night Dinner(Emmer wheat chapati of 80-90g approx.) at 9.30 PM. Spike at 10.50 PM was at 166 mg/dL. The next day FBS at 8 AM was 89 mg/dL.

Yesterday night at 9.30PM, i had lachcha parathas in an organic restaurant nearby. 1 hour spike was at 146 mg/dL. PPBS was 151 mg/dL. FBS today morning at 07:05 AM was 82 mg/dL.

Last week, i had my usual emmer wheat chapathi at 8.45 PM. 105 minutes later, my BS stood at 124 mg/dL. My FBS on the next day was at 99 mg/dL.

Need your suggestion here. Should i continue to have late dinner or the usual time? Which one will pull my HBA1C down?

what is emmer wheat ?


Otherwise called Long wheat, khapli Gehu, Samba Godumai, Jave Godhi


U r taking medicine or not?


No. I'm not on any medication


Dear Barani

Good to see your readings and this is without any medication - Am I right ?

How much is your current HBa1c?

Everybody's body reacts differently and one has to find out what suits him the best. If late eating is helping you, you must cultivate that and measure your HBa1c.

But suggest to keep a watch on Spike such as 166! On that night did you take something else ! Or the portion was high ?

I think your overall calorie intake must be very much less than your BMR. That is why your overall FBS has come down drastically end of the day !


Dear Namaha,

Yes. I'm not on any medication. My current HbA1c is 6.7. It has come down from 6.9(took 3 months ago).

Yes. I had gone to a restaurant that night and had slightly heavier than usual dinner. Hence the spike.

I just repeated my usual amount of emmer wheat chapati yesterday night at 9PM instead of 9.30PM. My FBS today morning was 99 mg/dL.

Planning to do more research for the next couple of months.


Please keep it up Barani. 6.7 without medication is a welcome event. But next step is you can still bring it down with diet & exercise and bring down to 6 to 6.5, given the wealth of information is posted under this column.

Also keep a watch on your TCG / HDL ratio. This ratio also an indication of insulin sensitivity/ resistance and long term CV risk. Should be less than 2. Ideal is 1.

Best of luck !


Thanks Namaha. I will definitely try to bring it down to less than 6.5.

Thanks for your inputs on TCG HDL ratio. It is 5+. My Lipid profile has not improved much for the last 9 months.


What are your lipid numbers?


Total Cholesterol -> 232mg/dL (desirable < 200)

Triglycerides -> 91 mg/dL (desirable < 150)

HDL Cholesterol -> 47 mg/dL (desirable > 40)

LDL Cholesterol -> 166.80 mg/dL(desirable < 100)

VLDL Cholesterol -> 18.20 mg/dL(desirable < 30)

Non-HDL Cholesterol -> 185 mg/dL (desirable < 130)


It is 5+, what is this ratio?

Triglycerides -> 91 mg/dL (desirable < 150) / HDL Cholesterol -> 47 mg/dL (desirable > 40), is about 2 !!!

Total cholesterol to HDL = 4.94

The Triglyceride/HDL Cholesterol Ratio. What Is Ideal?

The TG/HDL-C ratio can easily be calculated from the standard lipid profile. Just divide your TG by your HDL-C.

However, when looking at the ideal ratio, you have to check if your lipid values are provided in mg/dl like in the US or mmol/L like in Australia, Canada, and most European countries.

If lipid values are expressed as mg/dl (like in the US);

TG/HDL-C ratio less than 2 is ideal

TG/HDL-C ratio above 4 is too high

TG/HDL-C ratio above 6 is much too high

If you are using mmol/L (most countries except the U.S.) you have to multiply this ratio by 0.4366 to attain the correct reference values. You can also multiply your ratio by 2.3 and use the reference values above.

If lipid values are expressed as mmol/L (like in Australia, Canada, and Europe);

TG/HDL-C ratio less than 0.87 is ideal

TG/HDL-C ratio above 1.74 is too high

TG/HDL-C ratio above 2.62 is much too high

In this article, TG/HDL-C ratio is provided as in the US (mg/dl).

Triglyceride/HDL Cholesterol Ratio and LDL Particles?

Recently, analyzing the number of LDL particles (LDL-P) and LDL particle size has become increasingly common. However, this method is not universally available, is expensive, and has not been widely applied in clinical practice.

High numbers of small, dense LDL particles are associated with increased risk for coronary heart disease in prospective epidemiologic studies. Subjects with small, dense particles (phenotype B) are at higher risk than those with larger, more buoyant LDL particles (phenotype A).

Interestingly, it has been found that the TG/HDL-C ratio can predict particle size. One study found that 79% of individuals with a ratio above 3.8 had a preponderance of small dense LDL particles, whereas 81% of those with a ratio below 3.8 had a preponderance of large buoyant particles.

Apparently, people with high TG/HDL-C ratio tend to have higher than average TG. Just like all other lipids, TGs have to be transported in the blood by lipoproteins; most are carried by chylomicrons and VLDL.

Example , Triglyceride / HDL ratio is 100 / 50 = 2. Low ratio values such as this one indicate good insulin sensitivity; which means that insulin is doing a great job helping to move glucose and amino acids from the blood into your cells.


Thanks a lot for the informative post


Please take a look at this link:


I learned a lot from this Phd person.

👍 Interesting read !



I stumbled upon the link, everydayhealth.com/speciali...

It says goal is to keep the ratio less than 5.0.

Could you clarify if you are talking about the same ratio?


It is imperative to offer full English of the terminology when we are talking cholesterol.


Dear Barani

I AM not able to open the link sent by you. If you can resend.

Sandy is right. Your TCG /HDL ratio appears to be within 2, though your HDL seems to be little low.

Many clinics have revised Min HDL required is 60.


Your TG/ HDL is ok, though you could increase your HDL to min 60. Your TG HDL ratio will further come down.

The other ratiio of TC / HDL will also reduce.

But please don't bother about TC and LDL.....Your liver will keep on producing Cholesterol to respond to inflammatory conditions in your body.

High LDL, High TC meaning you need to attack the root cause i.e. if at all you have inflammation in your body. You can measure C-Reactive Protein (CRP) and if it is more than 1, perhaps you need to take measures in terms of diet and exercise to reduce inflammatory conditions or if at all you have inflammation inside body due to some other underlying health conditions which needs to be investigated.

What is TCG?


Triacylglyceride also known as Triglyceride in short form.

The abbreviations form for the above term in medical literature is TG, TAG & TCG.


Please take a look at this link:

Googled, TG,TAG and TCG individually, sorry it is not taking me to triglyceride!!!!

May be you can hepl me here?


A triglyceride (TG, triacylglycerol, TAG, or triacylglyceride)

Your TG:HDL ratio is calculated on a fasting lipid profile.

triacylglycerol, TAG, or triacylglyceride

Triglyceride or Triacylglycerol, often shortened to TAG.

These two TAG and TCG are new to me! Now I understand TAG but,

A collectible card game (CCG), also called a trading card game (TCG), among other names!!!



If you are keen to spot the medical short form TCG for Triacylglycerol , there are a lot of research papers and peer review papers on fats , lipids. Google may not be able to help you much ! Still you can try to google it out if you write TCG Triacylglycerol or TCG Triacylglyceride!

One such article link is given below for your ready reference. Please go to "discussion" and read 4th paragraph onwards !



Thank you.


Is it possible that due to late dinner, Lever has also late released glucose in blood in morning?


It is because when you took late dinner your sugar level slowly got reduced but did not reach a level when you tended to be hypoglycaemic. Liver would release extra glucose only when the body gives a “very low level” signal to the liver so as to prevent hypoglycaemia. So, in the face of “No Release” of glucose from the liver your glucose level is as actual. If you continue to sleep longer fasting so that the sugar level gets further reduced liver would release glucose from its stored glycogen and you would find higher fasting sugar value. Thus liver is really safeguarding one from hypoglycaemia.


Thanks for the information. So, what do you suggest? continue having dinner at 9.30PM?


Let me ask you this question:

What time is yuor breakfast?

What time is you lunch?

What time is your dinner?

What time do you go to bed?

How many hours do you need to give before going to bed after dinner?

In answering these questions you may find an answer!!!!
