I'd be careful with LA weightloss...they were in court for quite a few things up here. Plus they do not have a good rep at all, well up here they don't. You're a lot better off signing up at a local recreation center and just starting to shop for healthy groceries. Remember, eating healthy doesn't have to be a chore or disgusting.
Exercise...and you need to exercise for a minimum of 20minutes before any of "the right fat" gets burned. So if you exercise for 15minutes you're not doing any good. Although it is better than nothing! It's best to always try and make sure it's at least 30minutes that you exercise for. Basically there are three types of exercises you need to do to keep your body healthy and to be fit/lose weight. Strength exercises, flexibility exercises and endurance exercises. Endurance exercises are things such as running, walking, swimming etc and should be done anywhere from 4-7 days a week. Flexibility exercises should also be done 4-7 days a week and they are things like yoga, dance, golf, tai chi, house work, barn work etc. Strength exercises are things like lifting weights or any form of weight training, putting groceries away, climbing stairs, mucking out paddocks etc and they should be done 2-4 days a week. Remember to start out slow and work your way up as it's very hard on your organs to suddenly start working very hard.
Eat 6 small meals throughout the day, do NOT eat big meals. ALWAYS eat breakfast no matter what. Lunch should always be your biggest meal out of them all. You should never eat before going to bed...a bare minimum of three hours before bed although it's best to go with four. So if you go to bed at 11pm then don't eat anything (you can drink water) after 7pm or 8pm at the very latest. Try to cut any and ALL packaged foods out of your diet. Do not drink any juice, if you want juice than have some fruit. Cut all "junk" beverages (any sweetened drink) out of your diet ex coffee, soda, alcohol etc. Don't drink energy drinks or sports drinks. Eat ONLY whole grain breads, pastas etc. Do not eat white breads or white pasta or white rice. Stop chewing gum because it gets your gastric juices "flowing" and sends "I'm hungry" messages to your brain. If you are “really hungry” but it's at a time when you are just bored, or right before bed then drink a big glass of water. Make sure you're having a BARE MINIMUM of eight glasses(8oz) of water per day, although it's recommended you have 12 glasses a day.
Eat things that are low in both sugars, and sodium (salt). You need to read labels, as often if it says "low in salt" it's very high in sugar. Or if it says, "low in sugar" it's often very high in salt.
You should be eating veggies and fruits as snacks and if possible at every meal. Remember that digestion starts in the mouth (well technically it starts when you start cooking but that's a whole other subject) you should be chewing your food a MINIMUM of 22 times prior to swallowing. You need to slow down and chew. This not only helps with digestion and absorption of nutrients but it helps you to eat less as your brain is given time to tell you you're full.
A lot of people find it makes it easier if they keep a food diary. Basically write down everything you eat and when. That way you can go over it, see what things you can work on. Educate yourself on the new Health Canada food guide. The old one was crap and so they've finally redone it.
Don't use fad diets...many of them have major flaws within them and some of them can cause damage to your body. You should only be losing a small amount of weight per month ( a max of approx. 10 pounds/month depending on the person) which is another problem with these fad diets.
Anyway, if you do all of that (or even just part of it) I guarantee you that not only will you lose weight HEALTHILY but you will feel great too! Oh and incase you're wondering the above information is from my many years of speaking with dieticians, naturopaths, nutritionists and doctors. So if this doesn't help you than nothing will. haha!
