Question 1

What is a calorie deficit?

Accepted Answer

A calorie deficit means eating fewer calories than your body burns. When you consistently eat in a deficit, your body uses stored fat for energy, which leads to weight loss. For example, if your TDEE is 2,500 calories and you eat 2,000, you have a 500-calorie daily deficit.

Question 2

Is losing 2 pounds per week safe?

Accepted Answer

For most people, 1-2 pounds per week is considered a safe and sustainable rate of weight loss. Faster rates may be appropriate for people with more weight to lose, but should be supervised by a healthcare provider. Very rapid weight loss increases the risk of muscle loss, nutritional deficiencies, and gallstones.

Question 3

Why should I not eat below 1,200 calories?

Accepted Answer

Eating below 1,200 calories per day makes it very difficult to meet your nutritional needs for vitamins, minerals, and essential nutrients. It can also slow your metabolism, cause muscle loss, and lead to fatigue, irritability, and difficulty concentrating. If your calculator result suggests below 1,200 calories, consider a slower rate of loss.

Question 4

What if I hit a weight loss plateau?

Accepted Answer

Plateaus are normal and happen because your TDEE decreases as you lose weight. When progress stalls for 2-3 weeks, recalculate your TDEE at your new weight and adjust your calorie target. Also verify your tracking accuracy, since portion sizes can creep up over time without you noticing.

Question 5

Will I lose muscle in a calorie deficit?

Accepted Answer

Some muscle loss is normal during weight loss, but you can minimize it by eating enough protein (0.7-1g per pound of body weight), doing resistance training 2-3 times per week, and keeping your deficit moderate (no more than 500-750 calories per day). A slower rate of loss generally preserves more muscle.

Question 6

How accurate is the estimated timeline?

Accepted Answer

The timeline is a mathematical estimate based on consistent adherence. In practice, weight loss is rarely linear. You may lose faster some weeks and slower others due to water retention, hormonal fluctuations, and other factors. The overall trend matters more than any individual week.
