Comprehensive bikini fitness diet plan for competition: 12-week nutrition program, macronutrient management, body shaping principles, maintaining hormonal balance and supplements for women.

The bikini fitness category requires a muscular but feminine silhouette — not too muscular, with emphasized shoulders, a narrow waist and toned hips. Nutrition must shape the body while maintaining hormonal balance, which in women is more sensitive to a calorie deficit.
Women react more sensitively to a calorie deficit. Overly aggressive cutting can disrupt the menstrual cycle. Recommended deficit: 200–350 kcal/d.
1.8–2.4 g/kg protein per day. It is believed that women better preserve muscle mass with a higher protein intake during a deficit.
3 low + 1 high carbohydrate day. This helps maintain metabolism and hormonal function during cutting.
Minimum limit: 0.8 g/kg fat. Less — you risk hormonal disorders. Omega-3 are especially important.
