Count calories in snacks.
Snacks are counted by multiplying how many you have by their average size, then measured as a share of the whole day. The share is the number that matters: snacking that runs past about 25 percent of intake tends to displace protein and fibre from main meals rather than adding to them. Weekly and monthly rollups exist because snack calories are small individually and substantial in aggregate — three 180 kcal snacks is over 16,000 kcal a month.
Snack energy
Daily snack kcal = snacks per day x average calories per snack
Share
Share of intake = snack calories / total daily intake x 100
These figures are population-average estimates for general planning only and are not medical or dietetic advice. Individual energy and nutrient needs vary widely with body composition, activity, medication and health status. Consult a qualified health professional or registered dietitian before making significant changes to what you eat, and especially if you are pregnant or breastfeeding, are under 18, or have a medical condition or a history of disordered eating.
No — planned snacks help many people hold to a goal by preventing the over-hungry state that drives large evening meals. The problem is unplanned snacking, which is both extra energy and the least well recorded.
If your snack total exceeds the daily intake you entered, one of the two figures is wrong. The share is capped so it stays interpretable, but you should reconcile the numbers before acting on them.
