The path to lasting weight loss may begin not in the gym or on a meal plan, but in the aisles of your local supermarket, where the choices you make determine what ends up on your plate — and ultimately, what fuels your body.
For many people, shedding pounds comes down to swapping ultra-processed foods for minimally processed alternatives, making every trip to the shop a pivotal moment in their weight loss journey. According to Mike Bohl, a licensed physician and Senior Director of Medical Content & Authority at Hims & Hers, the decisions you make in the supermarket are fundamental. “The decisions you make in the supermarket determine what’s in your fridge and what fuels your body,” he said. Walking into a shop without a plan, he warned, leaves dieters vulnerable to impulse purchases, while shopping hungry can be just as damaging, increasing the temptation to reach for calorie-dense foods.
The shopping list as your first defence
Crafting a strong shopping list is paramount when embarking on a weight loss journey, Dr Bohl stressed. A clear plan before you step through the doors not only prevents aimless browsing but also acts as a buffer against the clever placement of sweets and crisps — aisles that supermarkets typically stock together for maximum impact. But a list alone is not enough; how you shop matters too. Going to the supermarket on an empty stomach can sabotage even the best intentions, making it far harder to resist the brightly packaged treats designed to catch your eye at the checkout.
Protein: the foundation of every basket
When it comes to filling your basket, protein should be the starting point — and for good reason. Dr Bohl, who holds a Master of Public Health from Columbia University, a Master of Liberal Arts in Journalism from Harvard University, and certifications as a Personal Trainer and Nutrition Coach from the National Academy of Sports Medicine, explained that protein plays a dual role in weight management. “Protein helps preserve muscle mass and keeps you fuller for longer,” he said, adding that this satiety effect makes you less likely to reach for snacks between meals. The science backs him up: a clinical trial published in Nature Medicine found that participants on a diet of minimally processed foods lost twice as much weight as those on a nutritionally matched ultra-processed diet, with an estimated daily calorie deficit of 290 kilocalories compared to just 120. Over the course of a year, that gap can translate into substantial weight reduction, and protein is a key driver of that difference because it helps people feel fuller and more in control of their intake.
Dr Bohl recommends aiming for 20 to 30 grams of protein every three to four hours to optimise muscle synthesis and maintain steady energy levels — particularly important when appetite is naturally suppressed during weight loss. Affordable and versatile options are available at virtually every supermarket. Eggs are a cost-effective staple; tinned fish such as sardines, mackerel and tuna provide protein alongside beneficial omega-3 fatty acids; Greek yoghurt offers roughly twice the protein of regular yoghurt and is a good source of casein protein, which can be easier to tolerate for those with reduced appetite; chicken and turkey mince are lean choices; and pulses such as chickpeas, lentils and beans deliver both protein and fibre. Tinned pulses offer convenience, while dried varieties are even cheaper. Tofu and edamame beans are plant-based alternatives that also contribute fibre.
The importance of these protein sources extends beyond their nutritional profile. Because they are widely available and easy to use in different meals throughout the week, they make consistent healthy eating more achievable. Dr Bohl, who has contributed to outlets including Eat This, Not That! and The Dr. Oz Show and recently completed an advanced education certificate in Obesity Medicine, emphasised that protein staples are a practical foundation for any weight loss diet.
Fibre, vegetables and the frozen aisle
Once protein is sorted, vegetables packed with fibre should be the next priority. The NHS recommends aiming for five portions of fruit and vegetables a day, with 80 grams of fresh, canned or frozen produce counting as one portion. Dr Bohl advises shoppers not to dismiss the frozen aisle: frozen vegetables are nutritionally similar to fresh produce, often cost less and do not go off as quickly. Studies confirm that frozen vegetables retain most of their nutrients — sometimes even more than fresh, because they are frozen at peak ripeness — and their longer shelf life helps reduce food waste. “Spinach, broccoli, and mixed peppers are my favourites and worth keeping as regular fixtures,” Dr Bohl said. Other fibre-rich options include carrots, cauliflower, kale, mushrooms, peas and sweet potatoes, especially with the skin on. Budget-conscious shoppers can also look for “wonky” or oddly shaped produce, which is often cheaper and just as nutritious, or rely on root vegetables such as carrots, parsnips and onions, which have a longer shelf life.
Smart swaps: wholegrains, snacks and treats
When it comes to carbohydrates, Dr Bohl is clear: choose wholegrains over refined alternatives wherever possible. Brown rice, wholemeal bread and oats are all budget-friendly choices that help with appetite control. Other options include wholewheat pasta and quinoa. The NHS also advises swapping sugary cereals for wholegrain alternatives as part of a balanced diet.
Snacking, if unplanned, can undo much of the progress made during a supermarket trip. Dr Bohl recommends planning for it. His top snack choice is baby carrots, which are filling and require zero preparation. Other smart options include nuts and seeds (with portion control in mind due to their calorie density), Greek yoghurt with berries, hard-boiled eggs, hummus with vegetable sticks, and popcorn or rice cakes as healthier alternatives to crisps.
That said, Dr Bohl does not believe in cutting out treats entirely. Focusing on portion control, he argues, allows you to satisfy cravings without derailing your progress entirely. The key is to avoid the aisles where sweets and crisps are concentrated — typically placed together by supermarket design — and to be mindful of serving sizes, using smaller plates and eating without distractions such as television or phones to improve satiety awareness.
The bigger picture: strategy, labels and health
Weight loss ultimately comes down to hundreds of small choices, and getting your supermarket shop right is one of the most powerful places to start. Meal planning and a well-prepared shopping list are crucial tools for avoiding impulse buys, while reading food labels — paying attention to the traffic light colour coding for fat, saturated fat, sugar and salt — can help shoppers make informed decisions. Swapping sugary drinks for water is a simple but effective change. Frozen and canned produce, pulses and tinned fish are cost-effective options, and plant-based mince and meatballs are becoming increasingly affordable compared to meat.
The benefits of maintaining a healthy weight extend beyond the scale. The NHS notes that keeping to a healthy weight is an important measure for preventing varicose veins, as excess weight increases pressure on leg veins, which can damage the skin and contribute to venous leg ulcers. The health body advises putting your legs up when possible — for example, lying down with your legs on cushions — and trying not to injure your legs to help prevent bleeding. Regular exercise and a healthy, balanced diet are recommended for weight management, along with avoiding prolonged standing or sitting and elevating the legs when resting.
