I can only offer what I (think) I understand:

Fruits and vegetables are almost essential for a 'balanced' diet, but............they are full of carbs in so many cases. Not so much lettuce and cucumber, as examples, but any root 'vegetables' will have lots of sugar (carrots, turnips, beets, spuds...) and about the only 'safe' fruit to eat is blackberries, strawberries, and raspberries. Blueberries are okay, but sparingly because they have more sugar per unit of mass of consumption. Bananas and apples, mangos, most tropical fruits, are high in carbs. So, if you are of the mind that you need to limit carbs in order to minimize your system's genetically engineered way of producing triglycerides, then you should be very careful about both fruits and vegetable consumption. There are scads of websites showing the expected carbohydrate content of any food imaginable. Try to stay below 100 gms per day, and 75 grams is about where it would be ideal to be 'low carb'.
Alcohol is bad, so is any refined sugar and the foods in which they are often found, meaning almost all packaged foods are going to be suspect. Whole foods you must prepare yourself will always be both cheaper and better in terms of triglycerides.
At the bottom of any serious undertaking will be one's motivation. Motivation is key, and it must be watered and fed every day for it to be healthy and to thrive. One way to achieve that is through self-education. Read, read, read.
