Hi Robyn and
Well the fact that you have joined this forum shows that you are serious about your weight loss....
Firstly you have to see this as a lifestyle change and not a weight loss program...
Secondly remove that soda from your cupboards, it does absolutely nothing for your body and your thirst. Replace this with water so instead of reaching for that soda, drink a glass of water...
Thirdly keep a food diary for about 3 weeks and write down everything you eat even if it is a piece of chocolate, you will be surprised at exactly how much food you are eating daily... Once you know exactly what you are eating, you can start eliminating the unnecessary junk and replacing with healthier options...
Start walking 30 minutes a day....
And lastly, always come to 3FC for motivation, encouragement and support...
