Question: how many calories should a 40 year old man eat to lose weight?
Answer: Many meal plans for men use a standard figure for weight loss. Weight loss plans usually provide for about 1,600–1,800 calories per day for a man. This allows most guys to reach a 500–1000 per day calorie deficit and lose at a safe rate of 1–2 pounds per week. Again, however, age and activity level is very important.
