Okay, I am only going off of what I know from my own experience, a step-mother that is an extreme health nut and looking at various diets in the past.
A virtual all protein and fat diet is not healthy for a lot of people. Many people who do go on this diet require vitamins, replacing those that you don’t get from the foods that are restricted. Carbs are needed but they must be from whole foods.
A woman on another message board posted today that she has had pancreatic damage from the Atkins diet. Another woman said her mother lost 32 lbs but gained back 48 when she went back to a more “normal” diet. Whatever that is.
Anyhow, I will run around every place I go and tell people the news that I know:
Eat a healthy well balanced diet. Lean meats, oils like olive oil, whole grain breads and whole grain rice.
Take out the white bread, processed food like frozen and most canned (except for veggies) foods, white rice, etc…
Protein and fats are great to help with your hormone balance. Whole grains and such give you good energy without storing it as heavy since your body can process them more completely. Veggies and fruits are good for needed nutrients to sustain all parts of a healthy being.
Overall, from the knowledge I have in my silly brain is very simple, eat healthy foods. Stay away from refined flours, rice, sugars. Limit potatoes and corn (both are high starch with = high sugar.) Limit your intake of processed foods.
It’s okay to indulge in those things once in a while but people wonder why the average US citizen is gaining weight by leaps and bounds, even with all these “miracle diets” it’s because people are simply not eating right. Balance. Moderation. Understanding. And a very important part is to start eating healthy and listening to what your body wants. I find I crave fresh veggies more than I do beef. We had a family gathering and I ate more of the fruits and veggies than the streak that my father cooked and it was damn good steak.
