The actual basics are unglamorous, free, and fit on a postcard. If you are new to eating with any intention, here are the five things that matter, and the half-dozen things you can safely ignore for at least six months.<\/p>\n<div class=\"takeaways\"><h4>Key Takeaways<\/h4><ul><li>&#8211; Calories, protein, whole foods, water and sleep are the whole game for beginners<\/li><li>&#8211; Macro tracking is useful later, not now<\/li><li>&#8211; Fad diets work short-term because they cut calories, not because they are magic<\/li><li>&#8211; Supplements are rarely worth it before the basics are in place<\/li><li>&#8211; Consistency for eight weeks beats perfection for eight days<\/li><\/ul><\/div>\n<h2>1. Calories: the invisible input<\/h2>\n<p>You do not need to count them on day one, but you do need to respect them. Fat loss requires a deficit; muscle gain requires a small surplus. Everything else is rearranging the furniture.<\/p>\n<p>A rough rule for British adults:<\/p>\n<ul>\n<li><strong>Two meals, a snack, no seconds<\/strong> usually lands in a modest deficit<\/li>\n<li><strong>Three meals and two snacks<\/strong> usually lands at maintenance<\/li>\n<li><strong>Three big meals plus evening picking<\/strong> usually puts you in a surplus<\/li>\n<\/ul>\n<h2>2. Protein: the priority nutrient<\/h2>\n<p>Aim for a palm-sized portion of protein at each main meal. That roughly hits 1.6g per kg of bodyweight without any maths. See our <a href=\"\/blog\/protein-intake-uk-guide\/\">UK protein guide<\/a> for the cheapest sources by supermarket.<\/p>\n<h2>3. Whole foods most of the time<\/h2>\n<p>The 80\/20 rule is genuinely useful: 80 percent of the week comes from whole, mostly unprocessed foods, and 20 percent is whatever you actually enjoy. Not 50\/50. Not 100\/0.<\/p>\n<p>Whole foods that are cheap and boring:<\/p>\n<ul>\n<li>Eggs, chicken, tinned fish, Greek yoghurt<\/li>\n<li>Oats, rice, potatoes, wholemeal bread<\/li>\n<li>Any fruit, any veg, any salad<\/li>\n<li>Nuts, seeds, olive oil<\/li>\n<\/ul>\n<div class=\"tip-box\"><span class=\"label\">Pro Tip<\/span><p>Put the takeaway menus in a drawer, not on the fridge. You will order less simply because it is less visible.<\/p>\n<\/div>\n<h2>4. Hydration: easier than people pretend<\/h2>\n<p>Two litres of water a day for most adults. Tea and coffee count (yes, really). You will know you are short if your urine is dark yellow by mid-afternoon. No special bottles or apps required.<\/p>\n<h2>5. Sleep: the silent partner<\/h2>\n<p>Seven to nine hours. Under-sleeping wrecks appetite regulation, training quality and mood within 48 hours. Our piece on <a href=\"\/blog\/sleep-recovery-muscle-growth\/\">sleep and recovery<\/a> goes into the detail.<\/p>\n<h2>What to ignore for now<\/h2>\n<ol>\n<li><strong>Macro tracking apps:<\/strong> useful at month three, distracting at week one<\/li>\n<li><strong>Intermittent fasting, keto, carnivore:<\/strong> none beat a sensible diet you can stick to<\/li>\n<li><strong>Greens powders, collagen, BCAAs:<\/strong> expensive urine<\/li>\n<li><strong>Clean eating in the moralistic sense:<\/strong> food is not clean or dirty, it is just food<\/li>\n<li><strong>Weighing daily and panicking:<\/strong> use a weekly average instead<\/li>\n<\/ol>\n<h2>Start here, not with a spreadsheet<\/h2>\n<p>Pick three of the five basics and run them for four weeks. That beats overhauling everything on a Monday and collapsing by Friday. When you are ready to progress, the <a href=\"\/blog\/calculate-macros-fat-loss\/\">macro calculator<\/a> and <a href=\"\/blog\/first-month-fitness-plan\/\">first-month fitness plan<\/a> are the natural next steps.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ignore fad diets and supplements.
