Welcome to the madhouse It's always hard to "diagnose" these problem from a distance, but my thoughts are like this: You are in that difficult phase where your body is totally confused .... it is no longer getting the carb fuel it was used to and has not learned to burn the fat properly - you're in metabolic no-mans land! Noake's book is lekker with good recipes, but if you're eating 3 meals a day from it, that's a hell of a lot of energy dense food and I'm not surprised you're gaining weight. Aslo, I don't agree with Noakes that you can "eat as much as you want and still loose weight". That may be try for some folk, but not everyone (not me!). Conversely, Im not suggesting you go on a low calorie diet ... be sensible about portion control and learn to listen to your hunter signals (NOT an easy thing to do). One of the benefits of a hi fat diet is that the meals are satiating, so there is a natural tendency to eat less ... BUT, until you are fat adapted (another week or so), that benefit may not kick in. For me constipation is almost always caused by two things: 1. too much protein.This one is hard to really measure without counting calories, but a good rule of thumb is 2-3 portions of protein a day each about the size of your palm. 2. too little salad / leafy UNCOOKED greens. Salad is the thing! or steamed veggies (don't boil the buggers, it takes the nutrients right out of them). Add olive oil, parmesan, avo and blue cheese to the salad and you're good to go. If I was you I'd do the following. - throw away the scale (at least for another 2 weeks). that thing measures total weight not fat:muscle percentages or blood sugar or lipid profiles or any of the other meaningful measures. - take your waist measurement, and measure it every week. for us >40's that's the best outward measure of health. - you're 1 week in, so don't give up now .. that just sets you back by a week - cut back on the protein intake to just 2 meals a day. - reduce the amount of coconut oil ... it s a great energy source, but your body can't use it yet. Also stay away from bullet proof coffee style drinks. Eat your calories, don't drink them. - give some thought to this approach. http://www.nutritionj.com/content/7/1/30 Don't be confused by the work "ketogenic", this diet is not ketogenic for everyone, but I now know 9 people who have tried it and they have all benefitted in terms of kick starting weight loss. - keep a food diary. not accurate to the last gram, but make sure you capture everything you eat. This will help you later if you need to tweak the diet or go see a dietician, etc - hang in there. this is the difficult period, I promise it does get easier
