  1. I was 301 lbs 1 year and 9 months ago. I went on a LCHF lifestyle, and went from 301 to 193 as of 1/24/17. Happy holidays. My goal is 188 lbs. My Ketones 3.6 mmol, and blood glucose 78 mg/dL 👍🏾, I go to the gym only 3-4 times a week. It really works.

  2. Westman's great, but I don't have much time for the Atkin's corporation. I've been doing a whole-foods based ketogenic diet for over a year now and it's absolutely amazing in all ways (improved biomarkers, skin/nails/hair, energy level, memory, and so much more). I'll eat this way for life.

    However, eating 80% Mazola oil would put one in ketosis, and yet no one would call that healthful. Good food choices are important on a ketogenic diet (organic, grassfed, free range, etc.) but far more important are the choices in good fats. Atkin's bars, although I occasionally keep some around, are basically low-grade food choices. It's shocking to me that people still recommend aspartame for sweeteners rather than stevia.

  3. started keto diet this week. started taking wheatgrass yesterday. Having Rapid heartbeats. Woke up at 3am with Rapid heartbeats. Having them now, sitting up, or when lying down???? Help????

  4. I try to reintroduce carbs after 3 years without them but I keep getting serious depression, anxiety and insomnia everytime I try to get on them. Why on earth do I have problem digesting carbs now?? I'm desperate for a solution. Thanks!

  5. I am in low carb diet, I love the results, loose weight, high level of energy, and I want to pass the message to family and friends. I have family that have gout and i have learned that a high fat diet is a factor for gout. Can they go low carb high fat? Thanks

  6. High carb low fat vegan diet for 5 years left me with a super high cholesterol and extra weight 30 pounds extra and a whole slew of health problems and deficiencies. I even took supplements and ate health food no vegan junk food. Went li carb higher fat, dropped my cholesterol by over a hundred points in two weeks and doing so much better. Losing weight and feeling great. I am a believer in the lo carb. Thank goodness for these doctors willing to speak out and take the mud slinging from those opposed.

  7. in this century low carb is great because our grains are genetically modified and sugar is included everywhere.
    but i also say that you can not compare eskimos to everyone in the world.
    eskimos live in a different environment. you can not apply what eskimos eat to a hot asian or african environment example.  
    it has been studied that if you give eskimos vegetables they will develop health problems.
    so it is a yes and no. and people have to just get back to nature and find what is best for them

  8. All diet extremism is a scam. They are loose weight quick tricks. You are probably exploiting another area of your body to achieve the weight loss and then people just put the weight back of because they feel deprived. People just these magic diets appear better than what they are to sell the diet products and make money.
     Just eat a balanced healthy diet and count calories. If that is hard for you to do, just prepare your meals in advance, spend a day making your food and proportions for the week and put your meals in tupperware and date them. Also, move your body, exercise, get a step and step, dance, jump rope, ride your bike to work or the corner store. Feed your body good energy and use the energy. Some fats are OK, just use a little olive oil in your food, but measure the amount that you use. 
     People are fat, because of these extremist diets. Lose quick and gain it back. 
     Make a habit of eating right.

  9. recent work has shown that a high-fat high-cholesterol (HFHC)
    meal induces oxidative and inflammatory stress in addition to inducing an
    increase in plasma endotoxin (lipopolysaccharide [LPS]) levels and the expression
    of Toll-like receptor (TLR)-4, the specific receptor for LPS (1). In contrast, a
    high-fiber and fruit meal does not induce any of these changes.
    RESEARCH DESIGN AND METHODS— Fasting normal subjects were given 300-
    calorie drinks of either glucose, saturated fat as cream, orange juice, or only water to ingest. Blood samples were obtained at 0, 1, 3, and 5 h for analysis.
    CONCLUSIONS— Although both glucose and cream induce NF-B binding and an increase in the expression of SOCS3, TNF-, and IL-1 in MNCs, only cream caused an increase in LPS concentration and TLR-4 expression. Equicaloric amounts of orange juice or water did not induce a change in any of these indexes. These changes are relevant to the pathogenesis of atherosclerosis and insulin resistance.
