Question 1

What does IIFYM mean?

Accepted Answer

IIFYM stands for If It Fits Your Macros. It is a flexible dieting strategy that focuses on tracking macronutrients (protein, carbohydrates, and fats) rather than strictly eating "clean" foods. As long as you hit your daily gram targets for each macro, you can technically eat whatever foods you enjoy.

Question 2

Why is Keto so low in carbohydrates?

Accepted Answer

The Ketogenic (Keto) diet drastically restricts carbohydrates (usually under 5% or 20-50g per day) and replaces them with fat. This reduction in carbs puts your body into a metabolic state called ketosis, where it becomes incredibly efficient at burning fat for energy and producing ketones in the liver to supply energy for the brain.

Question 3

How are the grams calculated from percentages?

Accepted Answer

Macronutrients contain different amounts of energy:

• Protein: 4 calories per gram
• Carbohydrates: 4 calories per gram
• Fats: 9 calories per gram

The calculator takes your total calorie goal, multiplies it by the percentage you choose for each macro, and divides by these respective numbers to give you your target in grams.

Question 4

Can I build muscle on a low-carb diet?

Accepted Answer

Yes, muscle growth is primarily driven by progressive resistance training and adequate protein intake. While carbohydrates are the body's preferred rapid energy source for intense workouts and aid in recovery (via insulin spikes), you can absolutely build muscle on a low-carb or keto diet as long as your protein is high and you are eating enough total calories.
