As a bodybuilder (who fell pregnant while in full competition) I can debunk some myths that are already popping up here.

Firstly, DO NOT eliminate carbs. Your brain needs carbs to function. You need to make sure that you're taking in enough fat, carbs and protein to fuel your muscles. Otherwise your body will eat muscle first as it's easier to break down than fat. My fitness pal is a good site that can help you track how much of each macro you are taking in.

Do not run yourself silly with cardio. Yes it has it's place, but the more lean muscle you build, the more cals you will burn just sitting there. I went from 30% body fat to under 10% on 3 x 20min HIIT sessions a week. But you need to keep an eye on your diet and lift weights. WEIGHTS WILL NOT MAKE YOU LOOK LIKE A MAN!!! Any girls who start to look manly are on the juice. Trust me on this one. Build your muscle up and you will lose bodyfat. And 1kg of muscle takes up 1/4 the space of 1kg fat. ALSO, it is impossible to replace fat with muscle at a high rate on women, it takes years. You will see your measurements drop as the fat comes off, but ignore the scales. Go off your measurements and how your clothes fit.

So key points, eat well, eat smart, don't drink your calories (smoothies etc are full of hidden sugar and calories) but also don't go into starvation mode, stay above 1500 smart cals a day. Drink lots of water 2.5L + per day. Lift weights and be consistent. Eventually it does move.

If you want to talk about this more, please PM me. I hate seeing people go to starvation diet, high cardio and get nowhere while metabolically damaging themselves.
