Question 1

How many calories do I need daily?

Accepted Answer

Daily calorie needs vary by age, gender, weight, height, and activity level. On average, adult women need 1,800-2,400 calories and adult men need 2,200-3,000 calories per day. Use a TDEE calculator for a personalized estimate.

Question 2

What is the best macro ratio for weight loss?

Accepted Answer

A common ratio for weight loss is 40% protein, 30% carbs, and 30% fat. Higher protein helps preserve muscle mass during calorie restriction. However, the best ratio is one you can sustain long-term.

Question 3

How do I calculate calories from food labels?

Accepted Answer

Food labels list calories per serving. Multiply the number of servings you eat by the calories per serving. Note that labels can be off by up to 20% according to FDA regulations.

Question 4

Should I count calories or macros?

Accepted Answer

Both approaches can work. Calorie counting is simpler and effective for weight management. Macro tracking provides more control over body composition and energy levels. Choose the method that fits your lifestyle.

Question 5

How does protein affect metabolism?

Accepted Answer

Protein has a higher thermic effect than carbs or fat, meaning your body burns more calories digesting protein (20-30% of protein calories vs 5-10% for carbs). Protein also helps preserve muscle mass during weight loss.

Question 6

What is a calorie deficit and how much is safe?

Accepted Answer

A calorie deficit occurs when you consume fewer calories than you burn. A moderate deficit of 300-500 calories per day is generally safe and sustainable, resulting in about 0.5-1 lb weight loss per week.
