Take manageable bites of the situation and try not to become overwhelmed. Start by getting 2500 steps per day for a week as a minimum, then increase by 1000 pw until you are at 10k.
Food wise, keep prepared snacks in the fridge - cut up fruit, cut up veggies, boiled eggs, nuts, dates, etc Choose those over ‘shite’. Take a packed lunch to work. Meal plan so you don’t over buy and you have a plan for the week.
My go to ‘treat’ which I make is a popcorn rocky road:
You need:
Bar (and maybe another half bar depending on how much popcorn you have) of high content cocoa dark chocolate bar
Bag of microwave salted popcorn
Bag of mini marshmallows
bag of dried cherries or cranberries
Method:
Melt the chocolate in a large heatproof mixing bowl over a pan of boiling water until completely melted
Microwave the popcorn. Remove any unpopped kernels.
Mix everything together (it takes a while to get all of the popcorn coated in the chocolate.
Line a baking tray with grease proof paper
Spreaad the mixture over the paper making sure it is tightly packed into a rectangle.
Put in fridge to set
Cut into small bars about 7cm x 4cm then place into a lined Tupperware box. Keep in the fridge. Have one or two as a post meal treat instead of a cadburys bar etc.
Main thing is to be kind to yourself and to keep going. 7lbs is a great loss!
