Risk and Suitability
Risk Level
LowLow. A moderate deficit paired with adequate protein (1g per lb lean mass) keeps muscle loss minimal.
Suitable For
Most active women who want visible progress without feeling deprived. Good for people with moderate fat to lose who can stay consistent for 8-12 weeks.
Not Recommended For
Those with a history of disordered eating, or anyone under medical advice to maintain weight.
Adherence Tips
- •Track your food intake daily. What gets measured gets managed.
- •Eat at least 100g of protein every day to protect lean mass.
- •You have room for flexibility. One higher-calorie day per week will not derail progress at this deficit.
- •Focus on whole foods that keep you full: lean protein, vegetables, and fiber-rich carbs.
- •Weigh yourself at the same time each morning and track the weekly average, not daily fluctuations.
Diet Break Recommendation
Consider a 1-week diet break at maintenance calories after every 8-10 weeks of dieting.
