Why Zig-Zag Calories?
The human body is an adaptive machine. If you eat a fixed 1500 calories every day for months, your metabolism will eventually down-regulate to match that intake (Homeostasis).
The Cycle Strategy
By having "High" refeed days and "Low" deficit days, you keep your leptin hormones guessing. This can help maintain a higher metabolic rate while strictly adhering to the same weekly calorie deficit for fat loss.
Frequently Asked Questions
Should I choose Sedentary or Light Activity?
Most people with office jobs are Sedentary, even if they walk the dog or clean the house. Choose 'Light Activity' only if you actively elevate your heart rate 1-3 times a week. Overestimating activity burn is the most common reason weight loss stalls.
Accuracy of Mifflin-St Jeor?
The Mifflin-St Jeor equation is considered the "Gold Standard" for modern populations, proving more accurate than the older Harris-Benedict equation, which tends to overestimate calorie needs for today's more sedentary lifestyles.
