It sounds like you've plateaued... or reached a point where no matter how strict you're maintaining the diet... nothing happens. That "plateau" phase passes; but, it'll take a while... quite a few weeks, which feels like an eternity for a dieter . The temptation is to cut back on food intake or modify the diet... don't! Be patient and the weight will drop as the body is going through a necessary adjustment during this plateau period. I also lost a lot of weight on the Atkins diet. I started 9 years ago (my 2nd try with it)... went off last year (big mistake!) because the man that I was dating during that time didn't like watching me diet. So, I had gained some "dating" weight... but, fortunately, not a whole lot. I'm not dating that man anymore; so I'm now back on track with the diet. By the way, when I started Atkins (in 2000) I weighed 190 lbs. It took me 2 years to get down to 115 lbs. I stayed at 115 until last year, when I put on 8 "dating" lbs. I'm now down to 117 lbs. So, it's a truly effective diet. Congratulations and good luck on your continued weight control efforts.
There have been some other recent posts regarding the Atkins type diet, you might find them interesting reading. It's my understanding that this type of diet does not count calories or anything other than carbs. The general basis for losing weight is "calories in/calories out" - meaning that if you take in more calories than you expend, you will not lose weight. There are instances where medical issues make this more difficult or seemingly impossible - in which case you need to deal with those issues prior to starting a weight loss regimen. I recently learned this from my own experiences.
The problem with a diet of this type, where you are severely limiting any one food group is that as soon as you go off the diet, you gain the weight back again.
To lose weight successfully and KEEP it off, you need to choose a healthy eating style that you will be able to maintain for the rest of your life. That includes ALL of the various food groups in appropriate portion sizes. By limiting certain foods, you most likely aren't getting all the nutrients you need. By choosing a healthy eating style, you should be able to eat most of the things you really like - just not in large portions (ie: one small slice of cake rather than the whole cake)
I agree that you should not eat the "simple" carbs, such as items made with sugar, white flour, rice, etc as they enter the blood stream and are broken down quickly, which causes your blood sugar to spike. These carbs are used up quickly, which then causes your blood sugar to drop, making you extremely hungry, so you eat again and it becomes a vicious cycle.
That said, there are certainly carbs that your body requires and those are the "complex" carbs (fiber), such as those found in fruit, veggies, whole grains, nuts, beans, etc. This type of carbs fill you up faster and take longer for the body to break down so you will feel fuller longer. This type of carbs is also chock full of vitamins and minerals that your body needs in order to be healthy.
You mentioned ketosis - are you diabetic? If so, that's all the more reason for you make sure that you get complex carbs in order to stop the cycle of your blood sugar spiking and crashing. Complex carbs will help stop this cycle. It's also better to eat several small meals throughout the day in order to keep your blood sugar steady.
You also need to get in some "good for you" fats, like olive oil, avocado, etc as fats help you feel "satisfied" and are necessary for over all health. They can even HELP you lose weight.
Fish is a good choice for the omega 3 fatty acids, protein, etc. Other meats will provide protein and of course, red meats provide vitamin B12, which is essential for energy production.
Protein also helps fill you up and takes longer to break down, so you feel fuller longer. I try to include both protein and fiber (complex carbs) in each meal/snack.
Bacon, heavy whipping cream and some cheeses are loaded with saturated fats and calories, while not necessarily providing much in the way of nutrients.
All of the "healthy eating" must of course be joined with an appropriate exercise program in order to be successful. Remember: calories in/calories out = weight loss.
Last, but certainly not least - it was very appropriately pointed out yesterday in another post "Dr Atkins was, himself, overweight". Thank you JoyRenee.
