Abdominal fat is connected to higher triglycerides and these are connected to higher carb intake and is an indicator for metabolic syndrome, diabetes, and heart disease.
If you want to lower your triglycerides look at your carb intake.
Those triglycerides are also an indicator for inflammation which is believed by a great many people to contribute more to heart attack risk than cholesterol numbers.
Again, look at your carb intake.
Eating meals that are high in carbohydrates cause insulin spikes and blood sugar crashes (the bonk)... our bodies don't like this.
I never bonk.
