What happens to your blood sugar and hormones when you eat low-carb with more fat vs. more protein?
Effect of low-carbohydrate diets high in either fat or protein on thyroid function, plasma insulin, glucose, and triglycerides in healthy young adults.

When healthy young adults eat a low-carbohydrate diet with mostly polyunsaturated fat for seven days, their fasting T3 hormone levels drop compared to when they eat a low-carbohydrate diet with higher protein content.
When healthy young adults eat a low-carbohydrate diet high in polyunsaturated fats for seven days, their blood triglyceride levels after meals are lower than when they eat a low-carbohydrate diet high in protein.
When healthy young adults eat a low-carbohydrate diet high in protein for seven days, their blood insulin levels rise more after a meal than when they eat a low-carbohydrate diet high in fat.
When healthy young adults eat a low-carbohydrate diet that is higher in protein instead of higher in fat, their blood glucose levels after eating are lower two hours later.
In healthy young adults, eating either a high-fat diet or a high-protein low-carbohydrate diet for 7 days lowers thyroid-stimulating hormone (TSH) levels by a similar amount, suggesting that the type of macronutrient—fat or protein—does not determine the degree of TSH reduction.
