Your body uses carbohydrates as its main fuel source. Complex carbohydrates (starches) are broken down into simple sugars during digestion. They're then absorbed into your bloodstream, where they're known as blood sugar (glucose). In general, natural complex carbohydrates are digested more slowly and they have less effect on blood sugar. Natural complex carbohydrates provide bulk and serve other body functions beyond fuel.
Severely restricting carbohydrates to less than 0.7 ounces (20 grams) a day can result in a process called ketosis. Ketosis occurs when you don't have enough sugar (glucose) for energy, so your body breaks down stored fat, causing ketones to build up in your body. Side effects from ketosis can include nausea, headache, mental and physical fatigue, and bad breath.
In the plainest of terms: These simple sugars fuel our organs. While protein, fat and carbs break down into smaller molecules to provide energy, glucose (the simplest sugar molecule) is the preferred source. Our very smart and energy-saving bodies do everything in their power to provide enough glucose to get stuff done, including using fat and protein when necessary.
Hi Sam, it won’t work. You will be incredibly hungry and you won’t have any energy. The idea of the keto diet is to get your body used to use fat to burn energy not carbs. Since you won’t be eating carbs energy has to come from “something” and it can’t be protein. I can’t recall what happens when you have too much protein when doing Keto but it was something scary. In general, I do not recommend the Keto diet without some sort of supervision by your doctor or nutritionist that can watch your process and progress.
Hi Stacey, I can’t give medical advice and definitely recommend following your doctor’s recommendations. You can ask him/her if low carb would be better suited for you. Also, you may want to double check with him/her if the kidney concern was related to high protein, because that is a common misconception about keto – it is not a high protein diet/lifestyle.
I would agree with many, but not all of your points. “Fat and carbs don’t make us fat. It’s only processed fat (vegetable oil) and processed carbs (white flour and added sugar) in processed foods (foods with more than one ingredient) that inherently lead to overeating and weight gain.” I have also said this throughout my website and one of the biggest myths I try to bust is that we are not NO carb we are LOW carb. By removing processed food from our daily diet, we almost become low carb by default. Nutrient dense, low-carb whole foods are encouraged but not to be overdone. Lower carb diets reduce insulin resistance and inflammation. Lower carb diets, with healthy fats, gives a better blood lipid profile and lower TG which is the best predictor of heart health. There are so many benefits from eating nutrient dense lower carb whole foods.
Now I am having the same problem with my youngest when he turned 1 -_- BUT I have discovered a few months ago both my boys will happily scoff back a vege/chicken curry I make, so I make that once or twice a week (I roast up 2 big chickens and cook extra veges, then use the left overs the next day to make it. Or sometimes make up Cauliflower curry soup from the Wheat Belly book if cauliflower is nice and cheap, and use that.) Unfortunately they will only eat it with rice, but for me personally I would rather them have a decent amount of veges a couple of days a week than cut out the rice completely so it is a compromise I am willing to take 🙂
While some low-carb diets allow for the carbohydrates found in plant-based foods, others restrict them almost entirely — namely, the ultra-trendy ketogenic diet. Since these foods contain the highest amount of water and dietary fiber, it's crucial to consider both the short-term side effects (constipation) and the long-term ones (increased risk of GI cancers and decreased immune function).
Carrie, I highly recommend a support group. I personally know a woman “Amanda Rose” who recently lost half her body weight through the Keto Diet and intermittent fasting. You should totally join her Facebook Group. It’s called “Eat Like a Bear” and you can find it by entering the group’s name in the Facebook search bar. She is so amazing and so supportive for people struggling to lose the weight.
My numbers are all excellent. Take a look at my page on the cholesterol myth where I summarise some fabulous books on the subject. Once you go low carb, your triglycerides drop, HDL goes up and LDL becomes the larger fluffy type instead of the small oxidised destructive type. This is an incredible simplification but have a read and see what you think.
I started seeing a nutritionist, who has started me on a B-12 injection 2 times monthly, and a LCHF diet. He wants me to stay between 20-35 carbs daily for at least 3 months. He says I need to buy ketone strips, to make sure I don’t go into ketoacidosis, however, I am otherwise healthy, and not diabetic. Is this something I need to be overly concerned about? I’m on my 4th day of approx. 25 carbs daily, and other than a slight headache, I feel fine.

Hi. I stumbled on your site via FB. I follow a lot of the advice you offer already. I typically eat scrambled eggs with turkey, a piece of wholebread toast and coffee for breakfast, salad and breast of chicken with vegetables for lunch and something similar (chicken or red meat or salmon) for dinner, with 2 snacks of 3 rice cakes with 150 gr. of turkey and a protein shake if I go to the gym (weights training 3x week). In the first 3 months of eating like this my % fat went down from 17.5 % to 14 % (44 yr old male), while keeping weight constant, but another 4 months later I stay the same. I wanted to ask, if I want to continue to lose fat, should I:
Oh, by the way : We are prematurely killing our beloved pets with carbs. Dogs and especially cats need to eat meat, but commercial pet food is mostly corn & wheat, which was bad enough before being poisoned by weed killer (“Round-Up” which is soaked into all American grain today) …. Huge numbers of cats and dogs now suffer & die from kidney failure, and the only explanation is what we are feeding them. My kitties now get chicken and tuna, which is a lot cheaper than any ‘gourmet’ canned food. Cooking for them is kinda fun, for that matter.
