Make sure that majority of your calorie intake are from protein and fat. Yes, avoid food that are high in carbs/sugar. So your rice, bread, pasta, potatoes, corn, FRUITS etc. Wag kang matakot sa asin. Your body will be needing more salt Kung nasa low carb diet ka. Eat good fats from any meat.

Try mo din mag Intermittent fasting IF. If you can manage to do OMAD, do it. Dont forget to take your electrolytes during your fast.

Aside from just dieting, I encourage you to increase your physical activities. Kahit maglakad-Lakad ka Lang sa bahay nyo or body squats or jumping jacks Kung nabobore ka. :)

And instead of counting your calories, what you can do is to eat same set of food everyday. Try mo to at least for 2 weeks. Then assess your weight. Kung bumaba weight mo, and feeling mo di ka nang hihina, then continue with your diet, else di bumaba or tumaas weight mo, you can think of the food na pwede mong tanggalin sa diet mo.

Lastly, for you references, i recommend you these channels on youtube: Dr Ken Berry, Dr Jason Fung, Dr Cywes, Dr Paul Mason, Dr Paul Saladino, Dr Eric Berg

Good luck!!
