Lifting wieghts Doesn't let you loose weight!
If you lift wieghts more like you work-out and do boybuilding eventually through the principle of Overload you will gain more muscle (hypertrophy) and having more muscle than fat actually gives you a heavier weight!
Remember Fat is lighter than muscle
But if you do more Aerobic workout with the involvement of light weights and done for a sustained length of time like perhaps a straight 10-15 minutes for a start can actually burn fat and let you have that toned muscle minus the fat.
If you are Fat (naturally endomorphic) and you want to look slimmer, you start with a good aerobic training or plan, like running, swimming, jogging, cycling, brisk walking and stairclimbing or etc. for a sustained 10-15 minutes with the same speed.You increased the time by 5 minutes until you can have it sustained for 45 minutes long. and do this for a month time daily or 5 times per week you'll surely loose that fat and you will be thin.
But thats not all! Diet plays an important role in this Program of losing that fat. You choose a high fiber diet with a moderate amount of good unprocessed carbs and replace the bad fat with good fat like fish oils or plant based oils like olive and a good amount of lean protein fish will be a healthy intelligent choice for this.
If you will be done with the aerobic phase it will be good to start the building of the muscle phase. The more muscle you build the higher is your metabolism! By the end of the 1st few months of aero enroll yourself in a gym and have a good over-all compound exercise regimen to target major muscles and jump start your building of good muscles.
ANd who said supplements are needed to loose weight or fats? Do not drink any supplement since you can get all the natural vits and minerals out from the fresh fruits and veggies you eat. Unless you can really afford it and you are a movie star and you want that ripped body effect then by all means use it but supplements are for lazy people, those people who wants to have something but do not work for it. Like Raelly Work for it!
