Not to hijack but regarding calorie intake, I'm a 30 yo male, 6' 3", and over the past ~3 years I've gone from 230lbs to 260lbs. I'm fairly muscular even though I haven't lifted for a few years, like a football players body. I have a rowing machine and will use it for maybe 15 mins 3-4x/wk. Anyways, these last few years I have been way under eating (unintentionally). I usually will skip breakfast, then just have a coffee at the office and by 3 or 4 pm, realize I haven't eaten and will have a turkey sandwich. Around 7 or 8 I would eat dinner which usually is chicken or salmon, veggies, and rice or sweet potato. Sometimes in the morning I'd get a breakfast sandwich from Starbucks. On weekends i have a few beers and maybe pizza or some other junk food. So a little over a week ago I calculated my calorie intake on a day I thought I ate a lot and it was only 2000 calories. I believe severely undereating has had me in starvation mode and has caused weight gain over the years. I am always tired. I thought maybe I had a thyroid issue but got checked and I'm all good in that department. So a week ago, right after I realized how little i was eating, I intentionally started eating more with a goal of 3000 calories. Online calculators say my TDEE is 3500. I split it up into 5 x 600 cal low carb meals. I also rowed 3 days and did some bodyweight exercises here and there. At the start of the week I was around 257. Today I am 265. The highest weight of my life. Is this normal? Do you think my body is still on starvation mode and saving everything? Should I keep going with 3000 cal per day? I'm worried this will backfire and I'll balloon to 275, 300, or worse. When will my metabolism reset?
