@michaellin First, don’t be discouraged. Weight can be influenced by various factors like muscle gained, water retention, etc. Continue putting in the effort in your workout. Research and practice proper form in your exercises, try to push yourself to lift as heavy as you can with good form or increase the repetitions of your exercises if you can.
Second, as many have said, diet plays a very big factor. You already said you’re tracking your calories. That’s a step in the right direction. Weighing your food allows you to make adjustments and researching the calories of the food you consume allows you to make more informed choices.
Try to cook your meals if possible. The reason I’m saying this is if hindi tayo yung nagluluto, possible kasi na maraming na aadd na calorie-dense ingredients na di natin namamalayan. Things like butter, oils, sugar, cream, mayonnaise are just some examples neto.
Continue looking at healthier alternatives as snacks. I read your comment na examples ng snacks na cinoconsume mo is kwek kwek or cheese sticks. These are high calorie foods (fried and battered yung kwek kwek, plus yung cheese na gamit for cheese sticks are also pretty high in sugar and fat plus fried din). Nothing wrong with eating these per se pero you have to understand that they could pack in more calories than the “busog factor” they provide.
Don’t be discouraged and understand na fitness and health is a lifetime of learning. It’s a journey with lots of highs and lows, and tons of trial and error. Keep going lang.
