I am fat type. I started out fat at 90kg. At 165cm.

Great. And you think you know more than me in my own history from age 0 to now. Sigh.

Was or is?

I was all the way over weight from kid till secondary 3. At secondary 3 onward I don't get to eat much and I have vigorous excercise. I was OK in that 3 years. Weight was 60 or so. In college I balloon up to 70 with approximately 2000kcal (if you ask me to calculate and recall what I normally eat). The last 3 months of college I was in UK. In order to save money I had approximately 800kcal a day, and I walk 3km one way to uni. When I got back, I was 56kg. I loose most probably 14kg in that 3 months. After I got back that weight of 56kg stayed for 3 months. After that it goes up approximately 1kg every 1.5 months. I have no exercise, I have no control over the food that I eat. But hey, I am eating more now than any time before this. I am definitely not ectomorph.

You don’t have to eat clean to get results. You do need to eat quality foods for your body. What I mean by this is that your macronutrients (carbs,protein,fats) each have their own roles to play.

Carbs - main energy source, replenish glycogen stores
Protein - energy source, signals body to put on muscle (Muscle protein synthesis; MPS), ‘building block’ of muscles (Drink more water with increased protein intake.)
Fats - energy source, helps MPS, reduces Muscle breakdown (at least 10-15% of your TDEE)

If you eat junk food, you’ll use up your calories easily but your diet won’t be very functional.

Go google about calories in vs out. Eat between your BMR and TDEE to lose weight, above TDEE to gain weight. The composition of your weight gain/loss depends on your macros.

Exercise helps you to build/preserve muscles. Building muscle while losing weight is possible but not optimal. A traditional cut & bulk works better. Spot reduction doesn’t work. Muscles do not convert to fat; vice versa.

Prioritise compound movements (e.g squats, bench, deadlift) rather than isolations. Form>lifting heavy.

Linear progression programmes works well for beginners; e.g SS,GSLP,SL.

Building strength, muscle and reaching a certain body fat% takes a lot of commitment and consistency. It takes a LOT of time and effort to get HUGE.

Read and digest stickies before further asking questions.
Protip; don’t ask how to get toned...

If you check johnnykidz’s posts. You’d find out that he’s completely new to this. I’m just helping to the best of my ability.

I’m on this forum to learn. If I do make mistakes, I do hope to be corrected.

That's your target? Go vegan. No problem.
