wow, awesome. i just found this post and i wish i saw it earlier. i think its AWESOME that you are making a lifestyle change. alot of people cant or wont do it because its hard. most dont even attempt. im glad you're doing it for YOU. thats very important. you're getting alot of good info for free so i hope you are taking advantage of it. it seems you are and thats great. stories like this just put a smile on my face. making a decision to change your life because you are sick of the current situation is a powerful thing. you are the only thing that can stop you from suceeding. and you will succeed if you keep it up.
about he cardio, i didnt see anyone mention this but as far as your knee joints go, riding a bike would be better than a treadmill for the fact that you arent pounding your ankles and knees with every step. for heavier people that can lead to alot of problems. if you screw up your ankle or knee your life will CHANGE drastically. most people overlook that but its very important to keep your lower body free from all that stress. im not saying to stop using the treadmill, just giving you other options. so if you think your ankles or knees are starting to hurt or something doesnt feel right, use something other than a treadmill. something that is low impact.
also, as far as diet goes, try this. i eat these all the time all day long. take some raw sweet potatoes which are VERY good for you btw. they burn nice and slow. i think they are the BEST carbohydrate out there personally. anyway, and this is for EVERYONE, this snack is awesome:
take however many RAW sweet potatoes and peel them. then cut them into strips the long way. cut them as skinny as you like. i find the skinnier the better cause they are easier to eat. anyway, cut them the long way in strips and put em in a bowl and snack on em all day long. or put em in a bag and take em with you. if you cant finish em. put em in the fridge and if they dry up sprinkle some water on em. these are GREAT. trust me, try it everyone. its very simple. just cut some raw sweet potatoes in long strips and thatsyour snack. and i think they taste very very good too. so its not like you have to tortute yourself. eat these early in the day to give you energy later on. since you are trying to burn fat, i wouldnt eat them at night or any dry carbs at night for that matter.
about the sauna. saunas are alot like exericse in that you BURN CALORIES. the heat revs up your metabolism and you burn calories just by sitting there. 15 minutes in a sauna is equal to 50 minutes of jogging or burning 500 calories. also, it helps alot with circulation and flexibility and helps loosen your joints. basically makes your whole body feel nice n loose. also, very good for your skin. scratch your arm or some part of your body next time you're in the sauna and youll get alot of gunk. its gross but its good to get that stuff out. there are lots of health benefits to using a sauna. just be careful, too much of anything can hurt you. you dont want to pass out or dehydrate yourself.
i hope you've read this whole post, i know sometimes i dont read posts that are too long. keep us updated on your progress. i for one am VERy intersted and VERY proud of you and im cheering for you man. its awesome that you changed your life. consistency is KEY. results are cumilitive meaning the more results you get the better it is, like stacking something on another. just gets better and better.
anyway, KEEP UP THE GOOD WORK, you're doing AWESOME!!!!!
