Wholemeal Bread (per slice) — calories & nutrition

A medium slice of wholemeal bread (around 40g) contains approximately 88 calories. A thick slice at 50g is about 110 kcal. Two medium slices for a sandwich total around 176 calories before any fillings. These figures apply to standard supermarket wholemeal loaves — speciality breads with seeds, nuts, or added ingredients may be slightly higher. Always check the label for the specific loaf you are using, as slices vary in weight considerably between brands.

Yes — wholemeal bread is a Healthy Extra B (HexB) on Slimming World. Two medium slices from a loaf weighing 400g or less count as one HexB allowance. This is one of the most practical HexB choices as it covers a normal lunchtime sandwich. If your loaf weighs more than 400g — such as an 800g farmhouse loaf — the HexB portion size changes, so check the SW app for current guidance. You receive one HexB per day as part of your Food Optimising plan.

Wholemeal bread has a modest advantage over white bread for weight loss. The higher fibre content (around 2.5g per slice versus 0.6g for white) slows digestion, moderates blood sugar response, and increases satiety. Multiple studies have found that people who eat wholegrains regularly tend to have lower body weight and waist measurements over time. The calorie difference is small — wholemeal at 88 kcal per slice versus white at 95 kcal — but the fibre benefit accumulates meaningfully over weeks and months.

The key is using your HexB bread as part of a filling, satisfying meal rather than eating it as a standalone snack. Build a substantial sandwich with Free Food protein like chicken breast, tuna, or eggs alongside Speed vegetables such as lettuce, cucumber, tomato, and rocket. The combination of protein, fibre from the bread, and volume from the Speed vegetables creates a much more satisfying meal than the bread alone. Toasting the bread also adds texture that makes the eating experience feel more substantial and takes slightly longer to consume.
