Unfortunately I hate most forms of cardio, so I don't get it in regularly at the gym. If your main goal is to lower bodyfat, diet (including drinking a lot of water) is key, followed by lifting.
Keep carbs and fats down, protein high, and eat frequently. No time to eat? That's not acceptable!
Breakfast is my weak spot, so I usually use a protein shake for my first meal. I keep stuff I can just grab and toss into a ziploc baggie or disposable plastic containers since my life is usually on the go. Tuna even comes in dry pouches now...you can rip the top off and eat it with a plastic fork and throw it all out (I keep these at work as a snack meal). I grill up burgers and chicken breasts (4-6 lbs of each in one night) then keep it all in the fridge so it's ready to go. As I'm walkin out the door, I grab a chicken breast and eat it while I'm driving. The supermarket has precut salad mixes so I buy those and I'll grab a few hand fulls, put it in a plastic container, add in a crumbled burger, and my lunch is done.
I think moderate drinking on the weekends hasn't helped me, but it hasn't ruined me either. I usually just keep it to one night (that is my "cheat" night and I eat more carbs that night at dinner than usual too) and I drink either 2 or 3 martini's or mind erasers (vodka, kaluah and club soda). Adding in juices or regular soda's as mixers will just add sugar without the buzz so why bother? LOL My cheat night is just after my Fri. night work out and I make sure I get into the gym on Sat. as well.
I usually lift 5 days a week. I've brought my bf down from about 25% to 18% in about 7 months by eating clean and just lifting. My weight has remained about the same but I went from a size 12/14 to a 6/7 in pants.
I've tried clen and I'm using it for my third time right now. The first time it had no effect on me. The second time (a few weeks ago) it seemed to help slightly. I'm giving it one more shot now and increasing cardio since I hurt myself and can't lift like I normally do. I think it's a very individual thing though. My husband did a 2 week cycle of it and lost a good amount of fat even though he hurt his back and spent 90% of that time laying in bed. LOL Sometimes I hate him!
adpro...get away from the scale as a judge of how she's doing...the scale hasn't moved for me in months but my clothes keep getting bigger! I think it took me about 3 monts to really notice any major changes, but 3 months is a short period of time when you really think about it, so she should keep going. I'm 5'3 and around 145. I wouldn't have her start clen at this point, her body is still getting accustomed to the new diet and lifting...wait for a few months to see how she's doing on her own.
