Frequently Asked Questions

Do I need to count calories every day to lose weight?

No. Tracking every single calorie may not be necessary for you. Some individuals like tracking their portions and structuring meals instead. Find the method that works best for you to maintain consistency without developing a negative obsession over food.

Am I fat because I eat more on weekends?

Yes, as long as your intake over the week averages out to your target goal. If the additional calories you consume on the weekend cancel out your deficit during the week, then you'll slow down your progress. Build in flexible eating plans.

Does eating after 8 pm cause weight gain?

No, not necessarily. The amount of calories you consume, as well as the foods you eat, are more important than the time you eat them. But late-night snacking can lead to excess calorie intake, as you're eating when you're not hungry.

Should I consume the calories I burn off during a workout?

Devices that track calories burnt from exercise, such as exercise machines or fitness trackers, tend to overestimate the calorie burn and should not be considered precise. If you eat more because you're hungry from exercising, or the time spent exercising is quite significant, then eat to hunger accordingly.

Why am I not losing weight when I am in a calorie deficit?

Factors that influence weight variations include water retention, menstruation, digestion, medications, and miscalculated food intake or energy expenditure. Track patterns over longer periods (weeks) rather than focusing on what your weight is doing during a given day. If you're still not making the progress you want, work with an expert.
