Please don't take offense to this but I'm not even going to follow the link after the previous couple statements. Not only that but because I'm at work I can justify going on IFSQN but not looking at ads for stuff. lol
There is no substitute for exercise and diet. You don't need anything special for your diet regular foods will work just fine.
Do not skip breakfast and do not eat so few calories that your body goes into starvation mode.
I've lost 25 lbs (started at 241 because I couldn't believe I let myself get that heavy). My diet is not normal food.
Typically I eat 1200 to 1300 calories a day in ~6 "meals" of slim fast powder shakes with skim milk and Greek yogurt (I love Yopa). Experts would agree that I eat way too little. I don't listen to them I eat what a 120 to 130 pound person needs in a day (and I weigh nearly 100 pounds more)
Then I typically try to burn off around 600 calories of that food in a day. I do this as much as possible. Some days I don't work out so I take all 1200 to 1300 calories... some days I work out more and net about 150 calories. One day, after lunch, I was at -150 calories... I was so happy.
(Now the dietician is freaking out)
I'm not saying to do what I do. It may or may not work for other people. It may be an unhealthy calorie deficit for some but it works for me.
There are great smartphone apps for counting your calories like Myfitnesspal. It counts what you eat and subtracts what you exercise. I use it along with my Polar Heart Rate Monitor so I have a very close look at what I've eaten vs what I've burned.
