How do I lose belly fat? I have stopped all carbs.

Take high fiber low fat diet followed by detox diet. Drink lot of water everyday. Take small and frequent meals at regular intervals of 2-3 hrs. Avoid outside food completely. Ask me directly for customized diet plan for you 

The ideal weight for a 3 month old baby should be between 5-6kgs.

You can take murmura bhel / roasted chana / fruit chat / sprouts and vegetable sandwich at office as a healthy and low carbs high fiber snack to loose weight .
