Hi and welcome back!
Hormones play an important part in how our bodies respond to food and exercise.
Leptin is a circulating signal that reduces appetite, and is believed to increase physical activity and feelings of well being, but in general, obese people have an unusually high circulating concentration of leptin are said to be resistant to the effects of leptin.
A study published recently suggests that the consumption of high amounts of fructose causes leptin resistance and elevated triglycerides in rats. The high fructose diet rats subsequently ate more and gained more weight than controls when fed a high fat, high calorie diet.
Insulin is a hormone that increases appetite, decreases physical activity and feelings of well being by supressing leptin, as well as promoting the chemical dopamine which makes a person want to eat to get the feel good dopamine “rush”. It is the high level of sugar and the low level of fibre that are now in our diets from processed, manufactured foods that promote insulin production.
So by lowering your intake of sugars and increasing your fibre intake over the last few weeks you are likely to have lowered your leptin resistance and your levels of insulin, and in turn are eating less, exercising more and feeling pretty darn good!!

An interesting article here about the war between nutritionalists and industry re sugar. Industry comments that fructose Fructose itself is safe, they say "It's in the fruits and vegetables we eat every day. Mother nature put it there." My comment is yes, its natural to have fructose in the form of fruit and vegetables, with all the added benefits of fibre and vitamins and minerals but how natural is it when we are consuming fructose without the natural fibre, vitimins and minerals from the fruit itself. Also, if we are regularly eating fruit we are getting enough fructose in our diets, do we need more? We have to remember that too much sugar, including fructose, increases our risk of diabetes, cardiovascular disease and gout.
So, more reasons to keep following the Fat-scrap programme by reducing the unnatural sugars in your food choices and eating healthy natural fruit, vegetables and grains. x
Good morning all
Thank you so much to you all for all your really interesting comments over the past weeks - i haven't had the time to reply personally but i have enjoyed reading all about you. I am looking forward to tonight and i know exactly what you mean Jayne when you say you have used this poorly time as thinking time. I do that when i travel - i can physically (or should this be mentally) empty my head of everything apart from holiday (and family) and get to grips with the important things in life. I haven't my diary with me at work to fill in the last couple of days on the blog but will do so tomorrow (without fail). Look forward to seeing you later. xx
Morning Ladies, sorry been a bit lax in my blog writing, actually been really busy hence the reason (I think) in not shifting this cold! Still got a chesty cough, headache and having to take my inhaler, so not good (but can say I think I feel alot better than Jayne...poor you, you really have suffered and yes such a shame when you're on 'fat-scrappers', hope you're getting better each day!).
I've enjoyed reading your blogs, its great to see how everyone is progressing even if we dont see each other.
As I'm the only one at Sue's session today, I've suggested a dog walk instead, as dont think my coughing and spluttering will be much fun for Sue, plus we dont want the trainer unwell!!!
Have a good week Fat Scrappers! x
