Weight loss and Physical ativity tips are dime a dozen. Just need to explore and find out what works for you. But i will say one thing Dieting and Physical activity are hand and hand. You really wont see the best of results unless your dedicated to both. One thing that i like and its free is a program called body rocks. Its a daily 12 minute workout that you can do in your living room. For free.... Oh and did i mention its free? But seriously its a kickass exercise. http://www.bodyrock.tv/
for dieting.. there are millions and millions of different ways to go about it. But you really need to find out what works for you. but one of the many tools that may just help you (helped me alot) Is a phone app called MYfitness pal. (ALSO FREE) It makes you aware of exactly what you are putting down. Its a daily thing in which you record and log everything your eating. Its super easy to log since it has almost any meal you can think of and even has a bar code scanner allowing you update in seconds. It also gives you the abilty to set a daily calorie gaol and a long term weightloss goal to follow. Its may seem like something for women but i was am 6'2'' man and weighed in at 296 now down to 217 in 6 months.
Best advice anyone can give you though is commit yourself to healthy lifestyle and stay commited to it. find what works for you and stay with it.
