Well I wouldn't focus on loosing weight and eating less. Although it maybe necessary, any weight loss should be slow!
You will need to eat more when on insanity or exercise really but your body will change the fat into muscle.
I never, ever weighed myself, I think it is something to get too absorbed in. I just focus on the feeling on happiness and pride and I have completed the workout. Really smile and congratulate yourself and your friend when you have finished, feels amazing.
And yeah bodybuilding.com has some amazing recipes, you can get some really nice recipes and it made me discover food more - which is why I also became vegan. I take care in what I eat but I have also discovered so much that I never knew I liked! I thought being a vegan would be boring haha but things like Asian Style Mushroom and Bean Stir Fries keep you going!
So yeah to get rid of fat just find healthy alternatives for the unhealthy things in your diet. Don't cut anything out, don't do anything physco like eating 50 bananas a day aha. Soon you will see your fat turn into muscle!
If you are going to weigh yourself, I like to weigh myself before and after taking a **** just for the funnies. Once it weighed a quarter of a stone!!!
Good luck! xxxx
