Hi there!
As you will have already heard in other threads, something that sounds that easy - just can't be that good.
From reading all your posts it sounds to me like you are looking for the "Magic Formula" so here it is:
Eat well, Exercise More!.
No matter what we would like to believe, the only way to permanent, healthy weight loss is with a quality eating programme, and regular workouts.
After years of being seriously obese, and trying almost everything, I have finally found the answer to my weight problem. I have now adopted the Body for Life programme as a Permanent Lifestyle and I am loving it. Yes - it is hard work, Yes it takes planning and preparation - but is it worth it - YES!!!
If your brother is seriously looking to make a change in his life, then he needs to find a serious answer. (and it should be noted that there is NO need for him to be on a strict LOW CAL diet - he could eat a lot more and still lose weight)
I personally would recommend Body for life, (
www.bodyforlife.com) as a complete, balanced approach, but you should research and educate yourself to find something that makes sense to you.
I hope you both find a healthy way to achieve your goals
