@FatFemale I was once quite overweight and I can tell you, you don't need sleeves, slimming world or silly crash diets.
Start educating yourself and investing in yourself. Make a lifestyle change that will last for years, not just until next Christmas.
Start making small changes - they will add up to a big one and a change of mindset. Forming healthy habits over the next year will help in the long run.
Start asking yourself these questions :
Do you know/understand much about food/nutrition? Proteins, carbs, good healthy fats?
Do you drink much water? Do you get much sleep at night?
These are the fundamentals you should get down first. Once you understand nutrition and how certain foods are going to make you feel - i.e. - you can eat a 1500 calorie diet but what that 1500 calorie diet looks like can make you feel drastically different depending on what the foods consist of.
Drinking 2-3 litres of water a day is recommended. Start with a smaller amount and build it up. Over time, water will become your go to (I was addicted to Fanta at one point - then I would sometimes opt for a bottle of water, and gradually over time my cravings for sugary drinks faded and water became my new craving).
Lots of sleep will obviously benefit you and how you feel.
I do a lot of strength training now, and fell in love with the gym so I maintain my body that way. But you don't need the gym for weight loss. I started off with a fitbit and slowly increased my steps - 2K, 5K, 10K. I also took my DD swimming once a week. Could you do the same with your kids? - I also recommend a home DVD programme if you want get out for long walks. The 30 day shred is a good one for beginners. It will kick start things for you.
And remember - losing 7 stone will take time. Don't beat yourself up if you have a bad day or whatever - just keep going. Don't rush weight loss - slow and steady wins the race.
Good luck!
