🧪
Support Your Liver Naturally
Stay well-hydrated, eat cruciferous vegetables (broccoli, kale), limit processed foods, and get 7–8 hours of sleep. The liver is your primary metabolic engine — protect it.
🚶
Boost Your TDEE Daily
Add a 30-minute walk to your routine. This alone can increase your daily calorie burn by 150–200 kcal, equivalent to an extra meal's worth of metabolic activity each week.
🥩
Protein is the Priority
Aim for 1.6–2.2g of protein per kg of body weight to preserve muscle and boost satiety. Higher protein also has a higher thermic effect — your body burns more calories digesting it.
Meal Timing Matters
Front-load calories earlier in the day when metabolism is highest. Avoid large meals within 2–3 hours of bedtime to support quality sleep and circadian rhythm alignment.
