To give you some advice in this area - I hope I don't bore everyone. I have been on Atkins for over 8 years. It is a long term solution, it is not a "diet", it is a lifestyle choice. As Americans, we eat too much, we worry too much & are bombarded with too much. Even with low carb foods you can over eat & alot of them are processed (low carb or regular - processed is processed). Hence, the best advice to give anyone is to eat within moderation, cut back on processed foods & eat more natural foods. That is all that Atkins ever tells anyone. Most people don't get past the Induction Phase of the book and really don't understand what he's trying to say. Eat a more natural diet. That's it!! I have also come across many issues for myself regarding enough carbs & cycling. I have found that eating about 1/3 of a Mojo bar before I go out & cycle my 16 miles a day gives me the boost I need & does not affect my ketosis. I like the Mojo bars because they don't have corn syrup in them. Very bad stuff. Read labels, know what you're putting into your body. You are unique and you have to find your right groove when it comes to what makes you burn fuel the best. You have to go with how you feel. The best diet to follow is the one our grandparents had living in the midwest. Natural foods from a garden, no waffles from the corner market!! Try to look at everything you stick in your mouth - especially hydrogenated oils. Nasty, nasty, nasty. Those folks from the 60's & 70's that we thought were strange because they ate alfalfa sprouts & organic foods knew exactly what they were talking about!!
I had a total hysterectomy 5 years ago (including ovaries - oopherectomy) and have been on natural hormone replacement therapy for the last 3. It has been a rollercoaster ride definitely in trying to get everything balance, but that's another story!!
I have been cycling for a year and a half as my husband introduced me to it. WOW! I love it!! He has been cycling for 20 years and my first day on my LeMond Tourmelet I discovered very quickly two things - I MUST HAVE A WOMAN'S SEAT AND WOMEN'S SHORTS!!! Owee!!! Once I got those things, I have been happy as a clam!
Sorry, I got sidetracked........... as you get older it is much, much harder to lose weight as I have discovered even on low carb & natural hormones. If you feel good & your clothes fit good, you're awesome! And yes, muscle weighs more than fat - there will be a conversion of body fat & sometimes you can actually weigh more as you build muscle. That's just the way it is. You can always go to a fitness facility and have your percentage of body fat tested. That's the only way to know if it's fat or muscle.
Take care!!
