Question 1

How many calories should I eat a day?

Accepted Answer

It depends on your age, sex, size and activity level. Alberta Health Services publishes ranges for Canadian adults: less active women aged 19 to 50 need 1,800 to 2,100 calories, active women 2,250 to 2,350; less active men need 2,350 to 2,700, and active men 2,900 to 3,000. This calculator estimates your figure with a ±10% accuracy range.

Question 2

How many calories should I eat to lose weight?

Accepted Answer

A moderate deficit of roughly 250 to 500 calories below your maintenance level is generally considered sustainable. Larger deficits are harder to maintain, more likely to cost muscle, and more likely to end in a restriction and rebound pattern. Never go below about 1,200 calories a day for women or 1,500 for men without medical supervision.

Question 3

Does Health Canada recommend a daily calorie amount?

Accepted Answer

Not as everyday guidance. Canada's Food Guide deliberately removed serving sizes and counts in 2019, because caloric needs vary widely between individuals, replacing them with plate proportions and eating behaviours. However, Health Canada does publish Estimated Energy Requirements within its Dietary Reference Intakes tables, which are the authoritative Canadian reference values.

Question 4

What's the difference between BMR and TDEE?

Accepted Answer

BMR is the energy your body uses at complete rest typically 60 to 70% of your daily total. TDEE is BMR multiplied by an activity factor between 1.2 and 1.9, representing everything you burn in a day including movement and digestion. TDEE is the figure relevant to what you eat.

Question 5

How accurate are calorie calculators?

Accepted Answer

Within roughly ±10% for most adults about 87% of the time for non obese adults, 80% for underweight and 75% for people with obesity. On a 2,130 calorie estimate that's about ±213 calories, which is often larger than the deficit someone is planning. Treat it as a starting point and adjust based on several weeks of results.

Question 6

Is 1,200 calories a day enough?

Accepted Answer

For most adults, no 1,200 is roughly the recognised minimum for women, not a target, and Canadian health sources advise not going below it without medical supervision. Below that level it becomes difficult to meet nutrient requirements, and the risks include nutrient deficiency, muscle loss and hormonal disruption.

Question 7

Why did I stop losing weight on the same calories?

Accepted Answer

Metabolic adaptation. As body mass falls, the energy needed to maintain it falls too, so a fixed deficit produces progressively less change and eventually plateaus. The familiar 3,500 calories per pound rule overstates long term results for exactly this reason. Recalculating at your current weight is usually more useful than cutting further.

Question 8

Should I eat back my exercise calories?

Accepted Answer

Only if your activity multiplier doesn't already include them. If you selected an activity level reflecting your training, adding workout calories on top counts them twice the most common practical error with these calculators.

Question 9

Why does my smartwatch give a different number?

Accepted Answer

Wearables estimate expenditure from heart rate, motion and your profile using proprietary algorithms with substantial error margins, and different devices report different things some active calories, some total. Neither figure is precise enough to justify adjusting intake by small amounts.

Question 10

How many calories do very active people need?

Accepted Answer

Considerably more than standard estimates suggest. Alberta Health Services puts active men aged 19 to 50 at 2,900 to 3,000 calories, and people in physically demanding work or heavy training can need more. For this group, under eating is usually the greater risk.

Question 11

Do I have to count calories?

Accepted Answer

No. Canada's Food Guide is deliberately non numeric the Eat Well plate uses proportions rather than amounts and scales naturally to different appetites. Counting helps some people, particularly athletes and those with high energy needs, but it isn't necessary for most people and isn't what Canada's dietary guidance recommends.

Question 12

Is this calculator free?

Accepted Answer

Yes. No account, no email, no limits and we don't sell meal plans, supplements or weight loss programmes.
