Most people will choose to begin their carb-up on Friday night and end it before bed on Saturday. This is usually most convenient as it's when you are off of work and can relax and enjoy the process. If you aren't overly concerned with fat loss and are just using this diet as a way to maintain blood sugar levels, you can likely eat whatever carbohydrate foods you like during this period. If you are worried about fat gain though, then you need the math.
I would just keep to the same scheme as your breakfast, making sure you stay at around 400 calories pr meal with with 85% of those coming from fat. I am sure you will start seeing benefits. **Make sure to drink a lot of water too** and watch that you are having enough salt – get a good mineral salt, or eat something with enough magnesium. My dad started this diet and he is 85. After about 2 weeks he is a different man – more energy, and better sleeps.
The meal plan is designed to ensure you get three balanced, healthy meals a day that address fiber, satiation, and adequate protein intake. The greatest part of a ketogenic diet is the fact that it spares muscle loss, where a carb-based diet doesn’t. Weight lost in a high carb, calorie-restricted diet will often come both from muscle and fat, whereas with keto, you can burn fat without sacrificing muscle. This is referred to often as “body recomposition” and leaves you with a much more preferred physique after weight loss.
When it comes to starting the keto diet (or any diet for that matter), there's one thing all experts agree on. You *must* have a plan. "Never try to wing a keto diet," says Julie Stefanski, R.D.N., C.S.S.D., L.D.N., a dietitian based in York, PA, who specializes in the ketogenic diet. "Set a start date and get prepared by reorganizing your pantry, planning out meal and snack options, and purchasing appropriate foods and dietary supplements," she says. "The biggest reason people have a hard time sticking with keto is that people don't have enough interesting foods to turn to, and high-carb favorites win out over good intention. If you didn't buy foods at the grocery store that fit the guidelines, there won't be an easy option in the fridge when you really need it."
