Trans fat and saturated fat are two names for two numbers that a food table can print separately. Saturated fat in 100 g of whole egg is about 3.2 g, inside about 9.96 g of total fat. 1 Trans fat is listed on its own, when the table includes it.
A food can have a lot of saturated fat and a different trans fat number, even a zero, or the other way round. Read both numbers on that food. Do not add the saturated grams into the trans fat, or the other way round.
The NHS says that, like saturated fat, trans fat can raise the cholesterol in the blood. People in the UK eat more saturated fat than trans fat, so that page says the larger amount to cut is the saturated fat. 3
Saturated fat and trans fat are listed separately
A large egg is about 50 g once the shell is off. That is about half the 100 g the table uses. The table gives 3.2 g of saturated fat in 100 g. A large egg is about half of that, about 1.6 g. Total fat in the egg is about 5 g. Two eggs come back to about 3.2 g of saturated fat.
They are still two separate numbers, even when a label prints both. When the table prints both, add saturated grams only to other saturated grams, and trans grams only to other trans grams.
WHO's limits on trans fat and saturated fat
Do not mix the two fats when you add them up. If a packet prints 0.5 g of trans fat in the serving, add that 0.5 g only to the trans fat. Add the egg's 1.6 g only to the saturated fat.
WHO's healthy diet fact sheet caps trans fat of any type at no more than 1% of energy, and saturated fat at no more than 10%. The trans fat limit is the smaller of the two. On a 2,000 kcal day that 1% is about 2 g of trans fat, and the 10% is about 22 g of saturated fat, using about 9 kcal per gram of fat. 2 The NHS says an adult should have no more than about 5 g of trans fat a day. For saturated fat, it says no more than 30 g a day for men and 20 g a day for women. 3
How to add the two fats
If you take the egg's about 1.6 g of saturated fat and a packet that lists 2 g of saturated fat in the serving, the saturated total is about 3.6 g. If that packet lists 0 g of trans fat, the trans total from the packet is 0. That 2 g stays with the saturated fat. If the packet lists 0.5 g of trans fat, the trans total is 0.5 g and the saturated total is still about 3.6 g.
Even if you set one large egg's 1.6 g of saturated fat against WHO's 10% limit, that limit is still about 22 g on a 2,000 kcal day. Two eggs are about 3.2 g. A packet that lists 2 g of saturated fat brings a one-egg day to about 3.6 g of saturated fat. The trans fat cap is about 2 g on that day. A packet that lists 0.5 g of trans fat has used about a quarter of that 2 g. A packet that lists 0 g of trans fat adds no trans fat. Total fat in one large egg is about 5 g, from about 9.96 g per 100 g of whole egg.
Trans fat on a Horlicks Protein sachet
If you have a Horlicks Protein sachet on the same day as the egg, read the sachet's own fat lines. The sachet lists 24 g of protein in 36 g. Any trans fat it prints is added only to other trans fat. Any saturated fat it prints is added only to other saturated fat. The egg's 1.6 g of saturated fat stays with the egg. The Horlicks Protein milkshake is a 240 ml bottle with 20 g of ultra-filtered milk protein. Any trans fat printed on that bottle stays on the trans fat total.
Summary
Trans fat and saturated fat are two separate numbers, and both can raise the cholesterol in the blood. Add saturated grams only to other saturated grams, and trans grams only to other trans grams. A large egg has about 1.6 g of saturated fat and about 5 g of fat in total. You get the trans fat from the food whose label prints it. On a 2,000 kcal day, WHO's limit is about 2 g for trans fat and about 22 g for saturated fat. The NHS says about 5 g of trans fat a day, 30 g of saturated fat for men, and 20 g for women. A Horlicks Protein sachet lists 24 g of protein, and any trans fat printed on it is added only to other trans fat.
