Re: Help! I need to lose 50lbs in 4 months for my wedding!
Firstly congrats on the wedding! Great news.
Re weight loss, that's a big target and to achieve it will take a COMPLETE LIFESTYLE CHANGE. That said, if your determined, it is a goal that you can achieve.
As you've rightly said the way to do it is changing your diet and exercise. Remember if, you put less calories in you'll have less to burn. I'm definitely not advocating starving yourself, but I am saying that you will need to change the foods you eat and from now on until the big day- it's healthy, healthy, foods only. Fresh fruit, veggies, wholewheat carbs, protein with no fats (Let me know if you want some healthy, easy, low fat but great tasting meal ideas/meal plans).
Re exercise, when I run, If i go at a 7min mile pace (which is quite fast and probably not achievable for a beginner) for 30/35 mins, I burn about 400 calories.
So, for your exercise I would suggest - running a couple of times a week (starting slowly - this will become so much easier to do so quickly - you will be surprised), walk where ever you can and a group exercise a couple of times a week, aerobics at the local gym - this will burn calories like running but also tone the wobbly bits. Please don't get caught up with having to burn exactly 835 cals. Everybodies body works differently and the main thing is you are burning them.
A GREAT exercise to really drop the pounds in Bikram Hot Yoga, this is also amazing for having some mental time out. A word of warning however, it is tough. It is 1hr - 1.5hr (depending on the class) in a room heated 40 degrees, the first session you will think you are dying! You need to give it at least 3 sessions, then there is the chance that you will become totally addicted to it! They also do intense courses. Could be worth considering.
Does that help at all?
