I feel that at 68 years of age (I am sure someone made a mistake because I feel 35 max), I can bother your girls and boys with my advice: keep counting your calories.
I did not count my calories for 5 days because I am convalescing following last Friday op, and realise it would be easy to over eat. I am lucky I did not put on weight and actually lost a few hundred grams.
Now I love cheese and have a bit here and there, but I got carried away and kept thinking "i am within my limit" but forgot the bunch of grapes I had before or the extra cheese in the morning, and olives while making a salad. " a few won't hurt". I have been eating healthy and I am sure within my calories limit but it was close! If you have to stay home recovering, it is very hard not to want to eat.
Conclusion: do keep a record of your intake. It is easy for some extra to sneak in.
What I have learn from the 12 weeks is healthy eating. So glad I did, because it changed my life. I learn about food and drinks that I thought were ok but are not, About necessary fibre, cravings and so on. The only thing I have to keep at still, is to stick to those healthy habits so that it comes naturally. In my case I believe another 12 weeks is needed, because I have to think carefully. I have to be 100% sure I got rid of my unhealthy habits.
Conclusion: keep at it a bit longer.
Finally, the way I feel now is so wonderful that I just cannot understand why doesn't everyone do the same. There is so much to life, so little time, let's not waste it. All those enjoyments, even small ones, gives you so much pleasure, it is a crime not to go for it.
Even things like looking at yourself in the mirror and see a waist, a nearly firm bottom instead of a blob. To be able to cross my legs was such an achievement. I feel so normal. (Although I still have a bit more to loose, but getting there anyway) . I am happy and so should you because you are doing something about it. Go for it, Don't let pleasure pass you by.
