Jacket Potato for Weight Loss
A plain medium jacket potato at approximately 215 calories is an excellent weight-loss lunch base — high in resistant starch (which increases with cooling and reheating), naturally filling due to high water content, and genuinely low in fat. The topping is where calories accumulate. Baked beans (162 calories, 10g protein) is one of the best value toppings nutritionally — high protein, high fibre, relatively low calorie. Cheese and butter are the two highest-calorie additions.
🥗 Lower Calorie: Choose baked beans as your topping instead of cheese or tuna mayo. Beans add 162 calories and 10g protein to the potato, compared to 121 calories but only 7.5g protein for cheese (which also adds 10g saturated fat).
💪 Higher Protein: Top your jacket potato with 100g of cottage cheese instead of cheddar. Cottage cheese: ~90 calories, 12g protein vs cheddar: 121 calories, 7.5g protein. A significant protein upgrade at fewer calories.
🔄 Smarter Swap: Swap butter on the skin (102 kcal per tablespoon) for a light spray of olive oil before baking (approximately 10–15 kcal). The skin crisps equally well. Saves 85–90 calories per tablespoon of butter avoided.
