Learn to estimate your total daily energy expenditure and set calories to achieve neutral, negative, or positive balance, using BMR estimates, online calculators, and small daily adjustments.

Design a weight loss diet by creating a negative energy balance, balancing macronutrients, and prioritizing high protein; consider calorie cycling as an optional tool.

Identify protein-rich weight-loss foods like eggs, chicken breast, lean beef, tuna, and beans. Pair them with high-volume vegetables and fiber to boost satiety and support sustainable weight loss.

Take diet breaks to reset physiology and psychology by returning to maintenance calories after a calorie deficit. Reduce cortisol, ease hunger and cravings, and tailor break length by body fat.

Break through fat loss plateaus by understanding weight reflects water and body composition, recalculating calories, and tracking hidden calories and sodium to sustain fat loss.
